980/1550 WDM/Isolator Hybrid-WDIH

It is a combination of a 980/1550 nm Filter and a 1550 nm polarization insensitive optical isolator. Its signal operation wavelength ranges 1528~1564nm and 1570 to 1605nm. And its pump channel wavelength ranges at 965nm to 1000nm. 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’WDIH is a combination of a 980/1550 nm Filter and a 1550 nm polarization insensitive optical isolator. The WDIH is a low cost model with excellent performance including low insertion loss, high isolation, high return loss, low polarization dependent loss (PDL), and low polarization mode dispersion (PMD). This product offers integrated solution to EDFA application by combining more functions into a very compact package. All Rayscience’ products are Telcordia qualification tested.
