Product Description

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.




● 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


● Multiple packages available
