How to use the fiber coupler?

Carrier grade couplers are optical devices that enable the distribution or combination of optical signal power between different fibers. It is composed of the mutual exchange of the guided wave energy in the core region of the fiber by using different fiber faces. According to the type of fiber used, it can be divided into multimode fiber, single mode fiber and polarization-maintaining coupler.
Generally, a detachable connection between the optical fiber and the optical fiber is used. The two end faces of the optical fiber are precisely butted together, so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the light is intervened. The link thus has a minimal impact on the system. The operating temperature of the fiber coupler that is produced for production is between -25 ° C and 70 ° C, the insertion loss is ≤ 0.2 dB, and the number of repeated insertion and removal is ≥ 10,000 times or more. Therefore, the fiber coupler seems to be small, but it plays a big role in the extended transmission of the optical signal. The choice is better than the fiber jumper, which will not let you regret it.
