Green 1550(1585)nm Tap Coupler/
Isolator Hybrid Combination
TCIHG Series
Product Description
Oplink’s Tap Coupler/Isolator Hybrid Combination (TCIH) is based on pat-
ented athermal platform for optical device.This product is a combination of a
partial reflection filter and a polarization insensitive optical isolator that fea-
tures ultra low insertion loss, super thermal stability, and unparallel reliability.
The technology is a lead-free packaging platform and no epoxy in the optical
path.

Note:
[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 speci-
fied.
