Product Description

40Gbps QSFP+ eSR4 VCSEL + PIN 850nm Multi-Mode Fiber Transceiver Module 400M MTP/MPO-12 DOM For Date Center and Ethernet



  • High Reliability 850nm VCSEL technology
  • Electrically hot-pluggable
  • Case operating temperature range:0°C to 70°C
  • Power dissipation < 1.5 W
  • 40Gbps 850nm 400m QSFP+ Optical Transceiver
  • High Channel Capacity: 40 Gbps per module up to 10.5Gbps data rate per channel
  • Maximum link length of 300m links on OM3 multimode fiber or 400m links on OM4 multimode fiber
  • Digital diagnostic SFF-8436 compliant




Gigaopto’s GTQ-B08A4-04DC 40G QSFP+ eSR4 optical transceiver modules are designed for use in 40 Gigabit per second links over multimode fiber. They are compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-SR4.

The optical transmitter portion of the transceiver incorporates a 4-channel VCSEL array, a 4-channel input buffer and laser driver, diagnostic monitors, control and bias blocks. For module control, the control interface incorporates a Two Wire Serial interface of clock and data signals.Diagnostic monitors for VCSEL bias, module temperature, transmitted optical power, received optical power and supply voltage are implemented and results are available through the TWS interface.
