Introduction
Polarization-maintaining couplers are manufactured by Fused Biconical Taper (FBT) technique. The principle is that two fibers are fused by oxyhydrogen flame and pulled to subulate by using the special pulling device. Then the light inputed one length of fiber is splited to the other fiber, so is the light power. The ratio (Coupling Ratio) of the power distribution can be set as required.The entire process of the pulling process is to be monitored by computer,and can stop according to the setting spetral of the device.
Features
High reliability, High stability, High cost performance, Small encapsulation size, Low PDL, Low excess loss, Long-haul telecommunications, Various coupling ratio , Excellent Environment & Mechanical Stability, Epoxy free optical path.
The reliability of the products complies with all kinds of exprimental requirements of BellCore GR-1221-CORE & GR-1209-CORE.
Application
The fiber optical coupler application is widespread, mainly includes: optical amplifer, optical networks. Power monitoring, fiber sensors.
