Description
Reliable planar InGaAs photodiodes are packaged in hermetically sealed cans. KPDE020 is designed to provide high sensitive and low dark current features for DWDM applications. Its high speed response in spite of the large detection area of 200µm dia. can suitably applicable to OC-3 and OC-12 receivers. The coupling with a multi-mode fiber can be easily obtainable.
