Detailed Product Description


QSFP DD 400G DR4 PAM4 Fiber Optic Transceiver 500M SMF 1310nm MPO-12



This product is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for 500M optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s (PAM4) electrical output data.



  • QSFP-DD MSA compliant
  • Compliant to 802.3bs
  • 400G DR4 Specification compliant
  • Non-hermetic package design
  • 8x53.125Gb/s PAM4 electrical interface (400GAUI-8)
  • Maximum power consumption 12W
  • MPO connector
  • Supports 425Gb/s aggregate bit rate
  • Up to 500m transmission on single mode fiber with FEC
  • Operating case temperature: 0~+70℃
  • Single 3.3V power supply
  • RoHS-2 compliant

1. Average receive power, each lane (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant;      however, a value above this does not ensure compliance.

2. Receiver sensitivity is informative and is defined for a transmitter with a value of SECQ up to 4.9 dB.

3. Equation 3: RS= Max (-6, SECQ-7.9) (dBm), where

                      RS is the receiver sensitivitySECQ is the SECQ of the transmitter used to measure the receiver sensitivity

4. Measured with conformance test signal at TP3 for the BER of 2.4 E-4
