Low Insertion Loss CWDM Optical Add / Drop Multiplexer ( OADM )
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.CWDM OADM modules are available in single-sided (East or West) and dual-sided (East and West) configurations supporting up to four wavelengths.
Features
● Low insertion loss
● Protocol transparent (support 1G, 10G etc.)
● Based on thin film optics with epoxy free optical path
● Fully compliant with Telcordia GR1221, GR1209, RoHS, ISO
● Ideal for WDM ring structures or daisy chain applications
● ADD<==>EXP, DROP<==>COM
● Multiple packages available
