Functional Block Diagram

OSFP 400G DR4

General Description

The 400G OSFP DR4 are high performance, cost effective transceivers designed for utilization in 400 Gigabit Ethernet links over 500 meters of singe mode fiber. On transmitter side, the module converts four channels of 53.125 GBaud (PAM4) electrical data to four channels of parallel optical signals with data rate of 53.125 GBaud (PAM4). At receiver side, the module converts four channels of parallel optical signals with data rate of 53.125 GBaud (PAM4) into four channels of 53.125 GBaud (PAM4) electrical output data.

The product is designed according to the OSFP MSA. It is designed to meet the harshest external operating conditions including temperature, humidity, and EMI interference.
