CLX-1G-CWDM1290 Calix Compatible 1G SFP Transceiver

The CLX-1G-CWDM1290 is a 1G CWDM SFP tuned to the 1290nm grid wavelength, letting it share a single-mode pair with other CWDM channels through passive muxing. It uses a duplex LC connector, comes up coded for Calix hosts as a recognized module, and links without a configuration step. Carrying 1G on the 1290nm CWDM lane, it slots into an existing CWDM plan as that wavelength's member, and it streams live optical readings over DDM.
