1480/1550(1585)nmWDM/TapCouper/
Isolator Hybrid Combination
WTIH1514 Series
Product Description
Oplink’sWTIH 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.

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.
