QSFP28 100G CWDM4 10km

The QSFP28 100G-CWDM4-10km module is a highly integrated 4x28G transceiver focused on reach, bandwidth, density and cost for high port-count 100G systems, and client-side 100G interfaces. It is compliant with the 100G 4WDM-10 MSA, which is based on the CWDM4 MSA version 1.1 but alters some of the specifications to extend the link reach from 2 km to 10 km. It is interoperable with CWDM4 transceivers over a 2 km reach.


Features of QSFP28 100G CWDM4 10km

  • Reach: 10 km via SMF

  • Optical link budget: Supports 6.5 dB of link budget

  • Link budget assumes the use of KR4 FEC by the host

  • Uncooled CWDM DFB lasers, directly modulated

  • Electrical interface: retimed CAUI-4 per 100G Ethernet IEEE 802.3bm Annex 83E

  • User controllable Transmit Input Equalization and Receiver Output Amplitude

  • MSA-compliant performance monitoring via I2C interface

  • Fiber connector: SMF LC duplex connector

  • Hot-pluggable

  • 0–70°C operating temp

  • Power dissipation < 3.5W

  • RoHS6 compliant (lead-free)



Applications of QSFP28 100G CWDM4 10km

  • 100G CWDM4 Ethernet

  • InfiniBand 4x EDR
