LAN WDM Module

LAN WDM Module

Regular price $34.99

KOC’s LAN (Local Area Network) WDM is designed to meet industrial stringent size and loss requirement. Based on Thin-Film-Filter (TFF) and Micro-optics, this low loss LWDM features small form factor, ultra low insertion loss, high channel isolation, and unparalleled reliability. The technology is a lead-free packaging platform and no epoxy in the optical path. The LAN-WDM is Telcordia GR-1221 and GR-1209 qualified, and RoHS compliant.
