Description
Tested to Bellocore TA-NWT-000983 this very high speed and low capacitance InGaAs PIN Photodiode is ideal for datacom, telecom and general purpose applications. Its double-lens optical system is designed for single-mode fiber as well as for multimode fiber with core diameter up to 62.5m and when used in the Pigtal-3A package, the optical return loss is very high.
