Immersible 100G QSFP28 PSM4 DML 1310nm 2km/10km Optical Modules

GIGALIGHT 100G QSFP28 PSM4 immersible cooling optical transceiver modules are used for medium to long distance interconnections in data centers and are compliant with the 100G PSM4 MSA specification, as well as compatible with 100G Ethernet and InfiniBand EDR transport protocols. The series uses 4 pairs of parallel single-mode fibers with a central wavelength of 1310nm for transmission over distances of up to 2km (FEC enabled), with MPO12/APC connectors on pigtails and customizable cable lengths.


  • A component with one 100G QSFP28 PSM4 optical transceiver module and one single-mode MPO patch cord integrated on both ends
  • The module consists of four channels of 1310nm DML and PIN
  • Each channel supports a maximum transmission rate of up to 25.78125Gbps
  • Integrated CDR circuitry for both receive and transmit channels, with support for CDR bypass
  • Compliant with QSFP28 MSA and 100G PSM4 MSA specifications
  • Compatible with 100G Ethernet and InfiniBand EDR transmission protocols
  • Utilizes 1 pair of single-mode fiber for transmission, with a maximum distance of up to 2km/10km (FEC on)
  • Module power consumption is less than 3.5W
  • MPO12/APC connectors used for the patch cord, cable length customizable
  • Operating temperature range from 0°C to 60°C
  • Power supply voltage of 3.3V
  • Complies with RoHS environmental standards (lead-free)
