Product Description

2x2 1550nm 10/90 50/50 PM Fused Fiber 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, Ultra PC, Angled 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,
