1480/1550nm WDM/Tap/Isolator Hybrid-WTIH

It is a combination of a wavelength division multiplexer, tap coupler and an isolator in a compact package. Its signal operation wavelength is at 1530-1565nm and 1570-1605nm and its pump wavelength channel ranges from 1450 to 1490nm.Its isolation is 31dB more at single-stage and 45dB more at dual-stage.



Wide Operating Wavelength Range

Low Insertion Loss

High Channel Isolation

Ultra Low PDL & PMD

High Stability and Reliability

Epoxy Free Optical Path


Rayscience’ WTIH is a combination of a wavelength division multiplexer, tap coupler and an isolator in a compact package. This product has an extremely low insertion loss, a very stable tap-coupling ratio, high isolation, and high return loss. The WTIH is ideal for fiber optic amplifier applications. All Rayscience’ products are Telcordia qualification tested.
