19'' 1U Chassis CWDM OADM 8 Channels -40~85 °C

WAREX CWDM Add/Drop module operates for 8 optical CWDM wavelength from 1470nm to 1610nm, using high quality filters.There are 8 Channels Optical Add/Drop Multiplexers(OADMs) and 8x2 single-wavelength dual channel OADMs. Each module offers low insertion loss, optical monitoring ports tapping 2% of the optical light signals allowing live monitoring and troubleshooting of the CWDM signals, as well as the mixing of 1310 nm CWDM signals on the same fiber infrastructures. The modules fully support ITU G.694.2 and G.695.

The modules are based on a standard 19”1U Chassis building practice and offer a very easy installation and connection process. Two modules can be mounted into a 19” bracket. Industry practice wavelength color coding allows easy set-up and installation resulting in a true Plug and Play experience.
