1G CWDM SFP Transceivers

1.25G SFP optical transceiver modules are designed for Gigabit Ethernet. WDM (Wavelength-division Multiplexing) transceiver modules include CWDM) Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) modules. CWDM transceivers enable connectivity between existing network equipment and CWDM Multiplexers/DeMultiplexers (Mux/DeMux). When used with CWDM Mux/DeMux, CWDM transceivers can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) over the same single fibre. This increases network bandwidth and provides a cost-effective solution in long distance applications. Please refer to SFP Technology Overview for more details.

We supply fully tested compatible transceivers for over 100 vendors. With our compatibility guarantee you can be sure we only sell products that meet or exceed the vendor specification with compliance to all MSA standards and protocols. Each product is uniquely serialised and we proudly offer a lifetime warranty on all our products.
