  • 4 LAN-WDM lanes MUX/DEMUX design
  • 4x25G electrical interface
  • Transmitter:cooled LAN-WDM EML TOSA
  • Receiver:SOA+PD ROSA
  • Maximum power consumption 5W
  • LC duplex connector
  • Supports 103.125Gb/s aggregate bit rate
  • Up to 40km transmission on single mode fiber without FEC
  • Operating case temperature: 0℃ to 70℃
  • Single 3.3V power supply
  • RoHS 2.0 compliant

Applications

  • 100GE Ethernet
  • Telecom networking
  • Data Center Interconnect
