PD-LD Inc. offers 2 sizes of standard Silicon Avalanche Photodiodes (APDs) in several styles of fiber coupled packages. The semiconductors are available in two standard sizes: 230 micron or 500 micron active areas. Our Silicon APDs cover the optical spectrum from 550 nm to 1050 nm and are optimized for peak performance in the 880nm to 905nm region. These devices are available in fiber pigtailed co-axial packages or in connector style receptacle packages.

  • 230 & 500 micron areas
  • 500-1015nm Optical Spectrum

Devices can be pigtailed with any size optical fiber that is compatible with its active area size. Pigtails may range in core size from 3 micron to 200 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.


Standard ST, FC and SC housings are available in both panel and board mountable versions. These receptacles can be optimized for use with both single mode and multimode optical fibers.
