XFP transceiver

XFP transceiver is a 10 Gigabit Small Form Factor Pluggable optical transceiver, it is protocol independent,it is usually 850nm, 1310nm or 1550nm.XFP transceiver IS USED FOR for 10G bps of the SONET/SDH, Fiber Channel, gigabit Ethernet, 10 gigabit Ethernet and other applications.

We supply XFP transceiver with different Wavelenth and data rate, and the distance is available up to 80KM.Please contact us for more information.

 Beyond XFP transceiver is compliant with the 10G Small Form-Factor Pluggable (XFP) Multi-Source Agreement (MSA), supporting data-rate of 10.3125Gbps(10GBASE-LR) or 9.953Gbps 10GBASE-LW), and transmission distance up to 10km on SMF.

The transceiver module comprises a transmitter with 1310nm uncooled EML laser and a receiver with a PIN photodiode. Transmitter and receiver are separate within a wide temperature range of 0℃ to +70℃ and offers optimum heat dissipation and excellent electromagnetic shielding thus enabling high port densities for 10 GbE systems.
