100GBASE-ER4 QSFP28 Optical Transceiver Module

Description

ETSC’s MD95ES100 module is designed for 40km optical communication applications. This modulecontains 4-lane optical transmitter, 4-lane optical receiver and module management block including 2 wire serial interface. The optical signals are multiplexed to a single-mode fiber through an industry standard LC connector.

Features

  • QSFP28 MSA compliant
  • Hot pluggable 38 pin electrical interface
  • 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
