980/1550 nm WDM/Tap Coupler/Isolator Hybrid Combination

ACP’s WTIH is a combination of a wavelength division multiplexer, tap coupler and an isolator in a compact package. This product has an extremely low insertion loss, a very stable tap-coupling ratio, high isolation, and hight return loss. The WTIH is ideal for fiber optic amplifier applications.

All AC Photonics' products are Telcordia qualification tested.
