Kyoto Semiconductor develops high-speed photodiode with 400Gbps transmission speed

2020-06-30 00:30

Kyoto Semiconductor has developed a high-speed photodiode KP-H KPDEH12L-CC1C to support 400Gbps transmission systems that use PAM4 inside and between data centers.

Currently, we have achieved transmission speeds of mainly 100Gbps by bundling 4 lanes of 25Gbps.

There are growing demands in the market for 400Gps to 800Gbps transmission speeds.

The transmission speed per PD reaches 50Gps (= 400Gps/4 lanes/2 (PAM4.

The transmission bandwidth required for the PD to achieve this speed will be 35~40GHz.
