The PL-1700-IGA-AR0050 -FSA is a 50um InGaAs APD housed in a hermetic 3 pin coaxial package. The APD is coupled to a singlemodefiber pigtail. The low noise, overload tolerant LAPD 3050 coax APD makes the devices ideal for OTDRs, line receivers and any other light level detection/ signal transmission application.Devices can be pigtailed with any size optical fiber that is compatible with its active area size. Pigtails range in core size from 3um to 100 micron. One meter is the standard length, but any length or connector termination may be specified. Pigtails may be terminated with ST, FC, SC and LC connectors with either PC or APC polish.

Safety and Operating Considerations
This device operates under reverse bias voltage, and the polarity of the device can’t be reversed.
Operating the Photodiode outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with this component cannot exceed maximum peak optical power.
ESD PROTECTION—Electrostatic discharge (ESD) is the primary cause of unexpected laser diode failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling Photodiodes.
