QSFP28 100G SR4 100m

The QSFP28 100G-SR4-100m module is a highly integrated 4x25G transceiver focused on reach, bandwidth, density and cost for high port-count 100G systems, and client-side 100G interfaces. Each lane can operate at 25Gbps up to 70m using OM3 fiber or 100m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38-contact edge type connector. The optical interface uses a 12-fiber MTP/MPO connector.

  • 4 channels full-duplex transceiver modules

  • Transmission data rate up to 25Gbps per channel

  • 4 channels 850nm VCSEL array

  • 4 channels PIN photo detector array

  • Hot-pluggable QSFP28 form factor

  • Maximum link length of 70m on OM3 Multimode Fiber(MMF) and 100m on OM4 MMF

  • Single 1X12 MPO connector receptacle Hot-pluggable electrical interface

  • 0–70°C operating temp

  • Low power consumption < 2.5W

  • RoHS6 compliant (lead-free)



Applications of QSFP28 100G SR4 100m

  • 100GBASE-SR4 100G Ethernet
