The engineer solved our problem very quick, and the service is very good. Very professional factory.

—— Robert Lichtenstein-Canada

I had no concern, was buying and testing, so equipment is ok. So equipment and logistic is ok, we keep ordering and making business.

—— Anek – Thailand

I'm very satisfied with the media converter received, the OEM order quality is good.

—— Faize Akçaba-Turkey

E-link Sales are very professional, they give me not only product, but also solution. All E-link Fiber Media Converters and PoE Switches works well.

10G XFP Single Mode 1310nm 10km SFP Optical Transceiver Module



  • Supports 9.95Gb/s to 11.1Gb/s bit rates
  • Hot-pluggable XFP footprint
  • Maximum link length of 10km with SMF
  • 1310nm uncooled DFB laser
  • XFP MSA package with duplex LC connector
  • No reference clock required
  • +1.8V,+3.3V Supply Voltage
  • XFI and lineside loopback Mode Supported
  • -5ºC to 70ºC Operating Case Temperature
  • Diagnostic Performance Monitoring of module temperature,Supply Voltages, laser bias current, transmit optical power, and receive optical power
  • RoHS6 compliant (lead free)




  • 10GBASE-LR at 10.3125Gbps
  • Other optical links,up to 11.1Gbps



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.
