980/1550 NM 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. The WTIH is ideal for fiber optic
amplifier applications.
