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.
