Oplink Communications, Inc.
1480/1550nm WDM/Tap Coupler/Isolator Hybrid Combination
Oplink’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,
and a very stable tap-coupling ratio. Fiber optic amplification is the ideal application
for this product.
Oplink can provide customized designs to meet specialized feature applications. Also,
Oplink offers modular assemblies that integrate other components to form a full
function module or subsystem.
