Description
This family of PIN Photodiodes is designed for Datacom, Telecom
and General purpose applications. Their unique design combines high
bandwidth with high responsivity for single-mode as well as multimode
fibers up to 62.5m core diameter. The MF432 PIN Photodiode is
available in ST, SC, or Pigtail package.
Specially-designed connectors and clips for PC board assembly
are included in deliveries of MF432 in SC and Pigtail configurations.
The MF431 LED is the recommended transmitter for these PIN
photodiodes.
