Immersion 100G QSFP28 PSM4 850nm 2km/10km Optical Transceivers

FIBERSTAMP 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 SR4 optical transceiver module and one multi-mode MPO patch cord integrated on both ends
  • The module consists of four channels of 850nm VCSEL 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 IEEE 802.3bm 100GBASE-SR4 Ethernet transmission protocol
  • Compatible with IEEE 802.3by 25GBASE-SR Ethernet and InfiniBand EDR transmission protocols
  • Utilizes 4 pairs of parallel multi-mode fiber for transmission, with a maximum distance of up to 70m (OM3) or 100m (OM4)
  • Module power consumption is less than 2W
  • MPO12/PC 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)
