CWDM OADM Module
CWDM Optical Add/Drop multiplexer (OADM) is a passive optical device used in WDM networks for adding and dropping one/multiple CWDM channels into one or two fibers, while letting the rest of the wavelengths bypass to the needed destination. Through the use of CWDM technology, individual channels can be optically extracted from a fiber pair while allowing pass-through traffic to continue unobstructed through the bus or ring.
CWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) . Each CWDM OADM uses wavelengths that fall within the ITU-T G.694.2 CWDM grid standard from 1270nm to 1610nm with 20nm spacing.
