Isolator Hybrid Combination
WTIH1514 Series
Product Description
Oplink’s WTIH is a combination of a wavelength division multiplexer, tap cou-
pler 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 applica-
tions. Also, Oplink offers modular assemblies that integrate other compo-
nents to form a full function module or subsystem.

The maximum IL is under all states of polarization and within the full operating temperature and wavelength
ranges specified. Add 0.3dB on signal port IL for 10% tapping case.
