980/1550(1585)nm WDM/Tap Coupler/
Isolator Hybrid Combination
WTIH1598 Series
Product Description
Oplink’sWTIH 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.

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.
[2] All the parameters are excluding connectors.
[3] The mechanical tolerance should be +/-0.2mm on all package dimensions unless otherwise custom specified.
