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.
