DWDM (Dense Wavelength Division Multiplexers)

DESCRIPTION

- DWDM (Dense Wavelength Division Multiplexer) is based on a patented athermal platform for optical devices. This multiplexer features ultra low insertion loss, superb thermal stability, and unparalleled reliability. The technology is a lead-free packaging platform and contains no epoxies in the optical path. KOC DWDM is Telcordia GR-1221 and GR-1209 tested, qualified for uncontrolled environment applications, and is in compliance with industry green initiatives such as RoHS and WEEE.

KOC can provide customized designs to meet specialized feature applications.

KOC also offers modular assemblies that integrate other components to form a full function module or subsystem.
