Description:40GBASE-SR4 40G Ethernet 850nm QSFP+ Transceiver
Item #:QSFP-40G-SR

The 40Gbps QSFP+ transceiver is well suited for Infiniband and 40GBASE-SR4  /  40GBASE-LR4applications. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules. It is intended for use short reach applications in switches, routers and data center equipment where it provides higher density and lower cost when compared with standard SFP+ modules.


  • QSFP+ MSA, SFF-8436 compatible
  • Four independently addressable transmit and receive channels
  • Highly compact: savings of 60% on edge and board usage compared to four comparable SFP+ modules
  • Electrically hot-pluggable
  • XFP-like latch mechanism for ease-of-insertion
  • Digital Diagnostics Monitoring Interface. allows customer management and monitoring of key modules parameters, analogous to SFP+
  • Optical connectivity via industry standard MTP/MPO terminated fiber ribbon


  • High-speed interconnects within and between switches, routers and transport equipment
  • Server-Server Clusters, Super-computing interconnections
  • Proprietary backplanes
  • Interconnects rack-to-rack, shelf-to-shelf, board-to-board, board-to-optical backplane
  • 40GBASE-LR4 Ethernet links
  • 10GBASE-SR applications
  • 40GBASE-SR4 applications
  • InfiniBand SDR, DDR and QDR applications
