Main description:
100GBase QSFP28 LR4 1310nm 20km SMF DOM LC Optical Transceiver

  • High Quality OCLARO Chip
  • DFB+PIN, Built-in digital diagnostic function
  • ≤3.5W Low Power Consumption
  • Compliant to IEEE 802.3ba 100GBASE-LR4
  • Up to 20km reach for G.652 SMF
  • Hot Pluggable QSFP28 MSA Compliant
  • For Data Center and Telecom Applications

This product is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 input channels of 28Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data.
The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The high performance cooled LAN WDM DFB transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 20km links and compliant to optical interface with IEEE802.3ba Clause 88 100GBASE-LR4 requirements.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.


Our products have passed authoritative certification and complied with international quality standard
