GLOBALfiber 1-Channel CWDM OADM Module
The 1CH CWDM Optical Add/Drop Multiplexer (OADM) module enables a single CWDM channel to be added or dropped from a fiber pair while passing all other channels. Ideal for use in metro and access networks, this passive device features low insertion loss, high isolation, and compact steel housing.
