Features
Supply Voltages, laser bias current, transmit optical power, and receive optical power
Applications
Description
E-link LNK-XFP-10G-LR 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 DFB 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 10G systems.
