Product Description

1550nm 1x2 2x2  Fiber Optical PM Fused Coupler

Product Description

Lightwit Photonics' Fused PM Coupler exhibit a broad operating wavelength range of up to ±20 nm for 1550 nm region devices. For operation within the standard bandwidth of a splitter, it is best to order a standard center wavelength for lowest price and quickest delivery.

We have the capability to connectorize the fibers of fused splitters with all standard connectors such as FC, SC, ST, LC etc. and finishes (Super PC, CZPT PC, CZPT led PC [APC] etc.). As a component integrator, We can construct additional components directly onto the coupler fibers. Examples include tunable filters, variable attenuators, or collimators. By building these devices directly onto the coupler fibers,

* IL is 0.3dB(1310~1550) or 0.5dB(980~1060) or 0.8dB(780~850) higher for devices with connectors.

** RL is 5 dB lower, ER is 2 dB lower for each connector added. Connector key is aligned to slow axis.
