Values are referenced without connector loss

[1]

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.

Isolator Hybrid Combination

WTIH1514 Series

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.
