WTIH1598-S0081 Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – 980/1550(1585)nm WDM/Tap Coupler/Isolator Hybrid Combination
980/1550(1585)nm WDM/Tap Coupler/
Isolator Hybrid Combination
WTIH1598 Series
Product Description
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 inser-
tion 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.
