The 400GBASE-DR4 OSFP Finned Top optical transceiver is a high-performance module designed for short to medium-reach 400GbE applications over single-mode fiber (SMF).

It supports four parallel lanes of 106.25Gb/s PAM4 for an aggregate bandwidth of 400Gb/s.

Operating at 1310nm, the module uses integrated EML transmitters and PIN photodiodes to achieve up to 500m transmission with FEC.

It features an MPO-12/APC connector, compliant with IEEE802.3bs 400GBASE-DR4, OSFP MSA, and CMIS4.0 standards.

The Finned Top housing enhances thermal performance for data center and AI cluster environments, supporting breakout to 4×100G-DR channels for flexible network deployment.
