Applied Optoelectronics Inc., a provider of fiber-optic access network products for the internet datacenter, cable broadband, fiber-to-the-home and telecom markets, announced 100 Gigabits per second (Gbps) PIN photodiode (PD) arrays for high-speed optical receivers.

The high performance InGaAs PIN PD is a front illuminated photodiode with a large modulation bandwidth, high responsivity, and low dark current. The product is a 4×25 Gbps PD array, and is designed specifically for 100 Gbps transceiver modules for datacenter and 100G EPON transceivers for FTTH applications.

The PIN PD can also be used for PAM4 receivers used in our 200G and 400G data center transceivers. Besides the 1×4 array, the 25 Gbps singlet PD can also be used in 25G SFP28 transceivers for 5G wireless and 25G EPON applications.
