40G QSFP SR4 Fiber Optic Transceiver

The 40G QSFP+ SR4 is a 40Gbps, hot pluggable fiber transceivers for Infiniband QDR and 40G Ethernet data transmission. It provides full duplex, parallel interconnects: 4 transmitting / 4 receiving data lanes and each lane at data rate up to 10.3125Gbps. Distance support could be up to 100 meters using OM3 fiber and 150 meters using OM4 fiber. Each lane could also be configured as independent 10G Ethernet transmission. Therefore facilitate higher port density at 10G Ethernet. sunrisephotonics 40G QSFP+ SR4 is designed to meet the requirements of high speed, high density and low power consumption for applications in today’s data centers.

40G QSFP SR4 Fiber Optic Transceiver Features

  • RoHS-6 compliant
  • High speed / high density: support up to 4X10 Gb/s bi-directional operation
  • Compliant to industrial standard SFF-8436 QSFP+ standard
  • Low power consumption : less than 1.5W
  • Distance up to 100 meters by OM3 fiber and 150M by OM4 fiber
  • Reliable VCSEL and PIN photonic devices
  • I2C standard management interface
  • Excellent high speed signal integrity

40G QSFP SR4 Fiber Optic Transceiver Applications

  • 40G Ethernet (40GBASE-SR4)
  • Proprietary high speed, high density data transmission
  • Switch and router high speed backplane interconnect
  • High performance computing, server and data storage.
