FINISAR CWDM SFP Modules are used with Gigabit Ethernet and they comply with SONET OC-48 LR-2 (SDH STM L-16.2) standards, Gigabit Ethernet as specified in IEEE Std 802.3 and Fibre Channel FC-PI 13.0. They are compatible with SONET OC-12 SR and SONET OC-3 standards too. The FINISAR CWDM SFP Modules are designed to deliver data rate of 1.25Gbps, 2.67 Gbps, and 4.25 Gbps extending up to a length of 50km, 80km and 100km. Thus, these modules support inter-locations network, metro access networks and point-to-point networks. FINISAR CWDM SFP Modules are hot swappable interconnects with SFP footprint and come with in-built digital diagnostic function. Cozlink FINISAR CWDM SFP Modules accept 8 possible CWDM wavelengths and operate at temperature range of 0°C to 70°C. Cozlink CWDM compatible modules comply with RoHS and IEEE and are fully compatible with other CWDM SFP brands such as Juniper, Brocade, and Prolabs etc.
