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.

Armored fiber jumper

FTTH armored fiber optical jumpers, also called armored fiber optic patch cord, made by covering a series of stainless steel banding on the tight tube of 0.9 PVC ,usually used to link the optical transceiver and the terminal boxes. Besides, its special construction promises its stay directly in different harsh environment without additional protection, which prevents the fiber from damage and improves stability and security of the whole system. Furthermore, the unique stainless steel makes the products more flexible and the maintenance more conveniently.

We supply the Chinese armored fiber optic jumpers, cables and assemblies. Our products especially the armored fiber optic patch cords are totally owning the following characteristics:

high mechanic performance

reliable optical performance

leading anti-ultraviolet radiation function.

Fiber Optic Jumper

Fiber optic jumpers What is fiber optic jumpers? Fiber optic jumpers refers to a optical fiber directly link the equipment and components in the fiber optic networks, to facilitate the connection of equipment and management. Used to do from device to optical fiber wiring link jump wire. Thick layer of protection, which generally used in optical transceiver and the connection between the terminal box. The Structure of the fiber optic jumper: Fiber optic jumpers are similar with the coaxial cable, but there are no mesh shield inside it.The center is light propagation glass core. In the multimode optical fiber, the core diameter is 15 μ m ~ 50 μ m, roughly and quite substantially with the thickness of a human hair. And single-mode fiber core diameter to 8 μ m ~ 10 μ m. Outside the core surrounded by a layer of refractive index than core low glass envelope, in order to make optical fiber to remain in within the core. To the outside is a layer of thin plastic coat to protect the cuff. The classification of fiber optic jumpers: According to the transmission medium ,fiber optic jumpers can be divided into common silicon base fiber single-mode and multimode optical jumpers, and others such as plastic as transmission medium optical fiber jumper; According to the joint structure forms,fiber optic jumpers can be divided into: FC  , SC, ST , LC, MTRJ, MPO , MU, SMA, FDDI and E2000, DIN4, D4 and so on various forms. More common optical fiber jumpers can also be divided into FC - FC, SC, FC - FC - LC, FC - ST, SC - SC, SC, ST, etc. Single-mode Fiber : generally the color is yellow, connector and protective sleeve are blue; longer transmission distance. Multimode Fiber: generally the color is orange, some with gray, joints and protection are beige or black; transmission distance is short .
