How to select multimode ferrule

On March one of clients complained that part of the multimode ferrules cannot be passed through by multimode bare fibers during the production. After inspection in the production site, it was only found the diameter of the multimode fiber is thicker than the bore diameter of the ferrules.

Usually there are two different sizes for the bore diameter of multimode ferrules: 125.3-126.3 um, 126.5-127.5um. Once the bare fiber is built at the high limit of tolerance, its diameter should be 126.5um, even bigger. In this case, if 125.3-126.3 um ferrule is selected, you can image that they both mismatch. Therefore, when producing the multimode fiber optical connector, JFOPT draw up the rule to choose 126.5-127.5um type to avoid mismatch.

The question at the very beginning of this article, has been solved by replaced by 126.5-127.5um type ferrules.

Fiber optic cables connectors Manufacturer

After the Second World War, in 1946, despite the participation of many British scientists in the Manhattan Project, and formal agreement of a joint technology-exchange program, the United States government passed legislation that closed its nuclear weapons program to all other countries. The British government, not wanting to be left behind as a world power in an emerging arms race, then embarked on a programme to build its own atomic bomb as quickly as possible. The Windscale Piles The reactors were built in a short time near the tiny village of Seascale, Cumberland, and were known as Windscale Pile 1 and Windscale Pile 2, housed in large, concrete buildings a few hundred feet from one another. The reactors were graphite-moderated and air-cooled. Because nuclear fission produces large amounts of heat, it was necessary to cool the reactor cores by blowing cold air through channels in the graphite. Hot air was then exhausted out of the back of the core and up the chimney. Filters were added late into construction at the insistence of Sir John Cockcroft and these were housed in galleries at the very top of the discharge stacks. They were deemed unnecessary, a waste of money and time and presented something of an engineering headache, being added very late in construction in large concrete houses at the top of the 400-ft chimneys.

About fiber optic attenuator technique

Fiber optic attenuator technique data
UPC type return loss 50dB or greater
APC type return loss 60dB or greater
Working wavelength 1310nm or 1550nm

About fiber Optic Attenuator
Sometimes in the fiber optic network, people need to reduce the fiber optic light power level when it is transmitted from one equipment to another; fiber optic attenuator is a device for this function. The unit “dB”, usually from 1dB fiber optic attenuator to 20dB fiber optic attenuators, measures fiber optic attenuation level. This is called a fixed value fiber optic attenuator, each piece of the fiber attenuator the attenuation rate is fixed. There are female to female and female to male type attenuators, the latter is also called a plug type attenuator.

Adustable fiber Optic Attenuator
There are also variable fiber optic attenuator , usually is inline type, with an adjustable unit on the attenuator to change its attenuation level to a certain amount according to its capacity.

Fiber Optic Splitters Introduction

fiber optic splitter is a device that split the fiber optic light into several parts by a certain ratio. For example, when a beam of fiber optic light transmitted from a 1X4 equal ratio splitter, it will be divided into 4-fiber optic light by equal ratio that is each beam is 25% of the original one. fiber optic splitter is different from WDM. WDM can divide the different wavelength fiber optic light into different channels. fiber optic splitter divide the light power and send it to different channels.

Single window Fiber Optic Splitter and dual window Fiber Optic Splitters

Here the window refers to the working wavelength. Single window fiber optic splitter is with one working wavelength, dual window fiber optic splitter is with two working wavelength. For multimode fiber, the term means that the fiber is optimized for 850 nm and 1310 nm operation. For single-mode fibers, the term means that the fiber is optimized for 1310 nm and 1550 nm operation. For single window fiber optic splitter, its working wavelength usually is one of the above said wavelength.

Fiber optic pigtails description
If you cut a piece of fiber optic patch cable into two parts, it becomes two pieces of fiber optic pigtails. fiber optic pigtails is a piece of fiber optic cable with fiber connectors on one side of the cable, the other side is used usually for melting with other fiber optical cables. Usually fiber optic pigtails are 0.9mm cable diameter, because it is smaller size and fit for being put inside the fiber optic patch panel boxes or fiber optic splicing enclosures.

Waterproof fiber optic pigtail
Besides the commonly type fiber optic pigtails, we can also make it fan out structure with fiber optic fan out kit, and there is another waterproof fiber optic pigtails, this type fiber pigtails is with big diameter outdoor cable, with waterproof fiber optic connectors installed on it, usually used in harsh environment. They are made according to IEC standards, the products feature low insertion loss, high return loss, good interchangeability and repeat push-pull performance.

A New Kind Of Microphone Fiber Optic Cable

Fiber optic cables are everywhere, installed along roads and train lines, in buildings and under streets. And U.K. scientists have found a way to turn any length of fiber optic cable into a kind of microphone or remote sensor. They have decided to call it the worlds nervous system.

 OptaSense, a part of Qinetiq, has decided to call this new technology Distributed Acoustic Snesing, or DAS. This DAS enables companies to keep a watch on extremely long stretches of cable like railways, pipelines, and roads, in one area watching over a pipe almost 700 km long. With DAS, you can place a microphone every 30 feet.

 Thieves are often stealing cables or oil and now companies are using DAS as a detection system. Usually, thieves will dig out pipelines and then try to break open the pipeline, leaving gushing oil for them to drain from. The DAS system found evidence of an upcoming theft three weeks before it took place.

 By combining something known as Rayleigh scattering with sonar technology that Qinetiq developed for submarines, OptaSense was able to create what is basically land based sonar with DAS. Magnus McEwen-King, the Managing Director of OptaSense, discusses a trip to Monaco for testing the product in a real-world environment. After connecting the technology, he states that we were able to hear everything driving around Monaco: cars, even helicopters. Mr. McEwen-King states that the DAS monitors everything near the cable and is specific enough to detect tunneling below it, or a low flying airplane above it.

 The DAS is great for reporting heavy vibrations, but just how precise is it? Can it pick up voices and essentially be used as a bug? Mr. McEwen King says that is depends on how long the network cable is on a shorter cable, it is possible, with a longer cable, no. He added that dirt and soil tend to attenuate all frequencies higher than 500 hertz anyway.

 This technology can be used in an astounding number of ways; to track vehicle flow on the freeway, to keep an eye on tracking, to less expensive alternatives to ground radar for tracking taxiing airplanes at airports. DAS was installed at Qinetiqs headquarters to demonstrate its uses. Mr. McEwen-King tracked a car driving along the road. When it began to go faster, the tracking indicator changed color from green to orange, signaling that the car is getting very close to the speed limit. If the car went over the limit, the indicator will change to red. Combine this technology with CCTV and you will know exactly who was speeding. Watch out world, now not only is everyone always watching, now they can always be listening as well.

Armored fiber patch cable VS common fiber patch cable

Armoured fiber optic patch cables are with same types of fiber optic connectors as the commonly used types, the different is the cable itself. These armoured fiber optic cables are typically used for indoor applications, with outer diameter of 2mm or 3mm, just like the common types fiber patch cables .

The difference is armoured fiber optic cables are with stainless steel tape just inside the cable jacket and outside the Kevlar, This stainless steel unit provide extra feature as well as retain all the function that a common type fiber optic patch cable can give. Amored fiber optic cords are anti-rodent, and it can be handled as electric cables, it is not easy to get damaged or cut, and it can resist an adult step on it.

What is a pigtail

 

What is a pigtail
Pigtail known as a pigtail line, only has one end of the connector, while the other end is the
core of the breakage of a fiber optic cable, welding and other fiber optic cable core is
connected, often appear in the fiber optic terminal box, used to connect fiber optic cable and
fiber optic transceiversdevice (also used between the coupler, patch cords, etc.).
Pigtail contains  SM and MM.
Multimode pigtail is orange, a wavelength of 850nm, the transmission distance of 500m, for the
short-range connectivity.
Single-mode pigtail is yellow, there are two wavelengths, 1310nm and 1550nm, transmission distance
of 10km and 40km respectively.
ITU-T (ITU-T for the ITU Telecommunication Standardization Sector), the specification of the three
commonly used fiber: G.652 specification fiber ,G.653 specification fiber, compliant G.655 fiber.

What is the fiber attenuation

 

Optical attenuator as an optical passive devices for debugging which used for optical power in optical communication system performance, debugging fiber-optic instrument calibration correction, optical fiber signal attenuation. The use of the product is mixed metal ion attenuation of optical fiber, and can the  optical adjust power to the level required.
Optical attenuator uses:
Optical fiber communication systems, fiber optic CATV ,measurement of high-power optical devices used for the attenuation of the input optical power, avoiding the distortion due to the super leaving the optical receiver input optical power.
Optical attenuator Category:
According to the type of port can be divided into several categories as follows:
SC fiber optic attenuator: applied to the SC fiber interface with RJ-45 connector, it looks very similar, but the SC interface seems to be more flat some obvious difference between the inside of contacts, if it is 8 thin copper contacts, RJ-45 connector, if it is a Copper Cylinder SC fiber interface.
LC fiber optic attenuator: applied to LC optical interface connected to the SFP module connector, it uses easy to operate modular jack (RJ) latch mechanism made​​. (Commonly used in routers)
FC fiber optic attenuator: applied to FC fiber interface, external strengthen the way the use of metal fastening method for the turnbuckle. Generally used in the ODF side up (patch panel)
ST fiber attenuation: Application to ST fiber interface, commonly used in fiber optic patch panels, shell round in shape, fastening methods for the turnbuckle. (For 10Base-F connections, the connectors are usually ST type commonly used in fiber optic patch panel)

OTDR

OTDR (Optical Time Domain Reflectometer) is the main tool to maintain the test cable barriers,used to test the cable breakpoint location, in order to repair a timely manner to arrive at the scene to repair. It works according to the Rayleigh scattering, by collecting the backscattered signal curve analysis points. Here, the author detailed analysis of the barriers of the fiber optic lines to find and deal.
Part of the system blocking obstacles
If the obstacle is an obstacle to a system, under the premise of rule out equipment failure, precise adjustment of refractive index, pulse width and wavelength of the OTDR instrument, so that the measured core parameters to minimize the test error. Subsequently measured distance information and data matching, to confirm the obstacles point in the joints.
OTDR curve observed with the barriers Fresnel reflection peak (Fresnel reflection is a special case of Rayleigh scattering, which is a special phenomenon that occurs when mutations in the fiber refractive index), and data matching, and a connector distance close, the initial judgment for the box fiber obstacles specular fracture (fiber boxes fracture are large Fresnel reflection peak). Repair personnel to the scene, and engine room personnel to further judgment, and then processed.
If the obstacle point and the connector distance is quite different obstacles compared to cable. Hidden nature of such obstacles, if the positioning is not allowed to blindly find may be an unnecessary waste of manpower and material resources, such as direct burial fiber optic cable a lot of earthwork excavation, overhead cable detaching and attaching a large number of linked, will extend obstacles lasted. These barriers can be used as follows accurately determine the barrier point.
OTDR instrument accurate test with the barriers relative to the adjacent joints point distance (slim), Lengthening of the test are translated into the fiber optic cable length (skin), and then the fiber skin long converted into the size of the growth of the obstacle point to the precise positioning with the barriers location. The specific algorithm is as follows:
(1) slim translated into the skin length of La = (S1-S2) / (1 + P). Where La for the fiber optic cable of long; S1 is the relative distance of the test length; S2 to stay the length of the cable connector box of unilateral disk, generally take 0.6 to 1.0; P of the cable twist shrinkage, due to different cable structure spare fiber optic cable can be used the same model tested provided by the manufacturer of the indicators. P = (Sa-Sb) / Sb, Sa for the single-disk fiber optic cable testing slim; Sb single disk cable marked leather long size length.
(2) the calculation of the cable barrier point leather long size Ly, = Lb ± La. Where Ly is the leather long size of the obstacle point value; Lb box the root of the adjacent joint points of fiber optic cable length leather Size + - the choice of symbols according to the cloth of the fiber optic cable put side do not determine. Determine the value of the Ly, the specific location of the obstacle point can be determined according to the information. The method can reduce measurement errors caused due to the engineering data are not allowed to, instrumentation, and optical fiber refractive index deviation, to avoid long distance accounted for fiber optic cable length, more accurate test results. Practice has proved that this method is simple and effective.
Fiber optic cable the whole resistance obstacles
Optical cable line blocking obstacles, easy to find , usually external impact caused by OTDR measurement of the distance between the obstacle point and the bureau (station), combined with maintenance data, determine the location of the obstacle point command line patrol officers along cable route to see if building construction, aerial optical fiber cable is obvious strain, etc.,.Generally you can find the barrier point. If you can not find the method described above, you have to use the accurate calculation to determine the barrier point.
Optical fiber attenuation caused by obstacles
OTDR test system disorders core, if the obstacle is the attenuation of spatially variable, and can determine the basic obstacle point is located in a junction due to the bending loss. Box remaining fiber plate remain inappropriate or heat-shrinkable tube off to form a small circle, so I fiber radius of curvature is too small. In addition, the connector box water may cause an obstacle to the joints. Open the connector box, you can further determine the normal core around on the finger, its curvature radius is too small, then the OTDR test (1550nm) there will be a large attenuation point, the point of the attenuation and obstacles fiber attenuation is consistent with the barrier point is the point. And then carefully review the barriers to fiber without injury or disk small circle, if there is a small circle ,ampplify it  , otherwise reconnection treatment.
Engine room line terminal obstacles
If the disorder in the terminal room, in the obstacle-side test, OT-DR instrument purification no regular curve in the terminal test can be found in the normal curve of obstacles core test. For precise positioning, plus the period of the pigtail to avoid the instrument blind to the general length of less than 500m, the first accurate measurement of the pigtail length, and barriers to access fiber-optic test.

The above analysis shows that the fiber optic cable and fiber optic jumpers obstacles causes a lot, except the force of outside joints are more barriers. Therefore, we must strictly control construction quality, so in line with operating procedures, to strengthen the maintenance, set up a full, complete, accurate maintenance of information and constantly sum up experience in practice, in order to quickly find and deal with various obstacles.

fiber optic jumper

what's the meaning of MTRJ-fiber optic jumper?

We offer you the different kinds of  MTRJ optical fiber jumpers ,a piece of fiber with a black square connector,e.g.:

MTRJ-FC MM Duplex Fiber Optic Jumper,

MTRJ-LC MM Duplex Fiber Optic Jumper,

MTRJ-SC MM Duplex Fiber Optic Jumper,

MTRJ-ST MM Duplex Fiber Optic Jumper,

MTRJ-MTRJ MM Fiber Optic Jumper.

In general, MTRJ fiber optic jumper is a piece of fiber with two connectors, one of which must be MTRJ but the other can be MTRJ or others like LC FC ST SC. In the process of producing fibers, the essential parts are external box ,internal box, retaining ting, pressure welding ring, tail and the long fiber .Looking from a distance, it seems like a small snake with a square box head.

Considering the fiber optic buyers’ feeling, our products can also be customized in these places like the color of the fiber skin, and the material of the jacket PVC or LSZH or customized. But frequently ,we often list that orange stands for MM and yellow representative to the SM .All these above are the principles of our JFOPT.

The definition of the IL and RL

IL and RL

As we all know,IL and RL are the key parameters in the process of QUALITY checking ,just like water to the fish,indispensibility.

IL and RL are essential parameters in the telecommunication industry, NOW I’ll share something new with you. Most important is the definition:

IL is short for the insertion loss, and definitely Insertion Loss is the ratio (expressed in dB) of the signal voltage transferred from source to load without a filter, to the signal voltage transferred from source to load when the filter is inserted. Insertion loss is not a measure of filter performance in the power line equipment environment.

RL is short for the return loss, In telecommunications, return loss is the loss of signal power resulting from the reflection caused at a discontinuity in a transmission line or optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line.

IL and RL are really important parameters and also play an important role in the place of QUALITY CHECK, furthermore, different company has different standard when it comes to the IL and RL and in general producers will set 3 ranks for the fiber optic jumper buyers.
