Description
Overview
GAOTek WDM filter device OADM integrates thin film coating tech and a proprietary non-flux metal bonding micro-optics design. It assures low insertion loss, high channel isolation, wide pass band, low temp sensitivity, and an epoxy-free optical path. CWDM products vary single CWDM devices in glass or stainless-steel tubes, CWDM Mux Demux modules in ABS boxes. To mitigate insertion loss in WDM networks, a “Skip Component” can be added in CWDM Mux/Demux modules.
