1064/980nm Optical Filter WDM

Overview

The FT-1064-20 is a filter WDM that passes 1064 nm through the transmission channel while reflecting 980 nm through the reflection channel. Transmission insertion loss stays within 0.8 dB and reflection within 0.6 dB, with 25 dB of isolation at the reflection wavelength and 15 dB at the transmission wavelength. Channel flatness holds to 0.4 dB, and thermal stability is tight: 0.003 nm per °C for wavelength and 0.005 dB per °C for insertion loss. The device handles 0.3 W to 5 W of continuous power and operates from 0 to +70 °C. It suits CATV distribution, CWDM and DWDM modules, and passive optical networks.
