OSFP-400G-FR4 Compatible 400G OSFP FR4 PAM4 CWDM4 2km LC SMF FEC Optical Transceiver Module

OSFP 400G FR4 4x100G Optical transceiver module is designed for use in 400 Gigabit links over 2km singlemode LC duplex fiber. The module has 8 independent electrical input/output channels operating at 53.125Gbps per channel. The integrated GearBox in module converts the 8 channels of 53.125Gbps (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 106.25Gbps (PAM4) operation for an aggregate data rate of 400Gbp/s. The optical side of transceiver consists of 4 channels on CWDM4 1270/1290/1310/1330nm center wavelength. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and compliant with OSFP MSA.


  • Hot-pluggable OSFP form factor with non-hermetic package
  • Utilizes 56GB uncooled EML and 16nm DSP
  • Supports 2km transmission over SM fiber with host KP4 FEC
  • Operates at 106.25Gb/s (PAM4) per channel
  • Compliant with 400GAUI-8 electrical interface
  • Compliant with IEEE 802.3bs and QSFP-DD MSA
  • Supports receiver signal strength indicator (RSSI) and transmitter output power monitoring (TOPM)
  • LC connector integrated with optical Mux and De-Mux
