Description
A high-speed InGaAs PIN photodiode is integrated with a transimpedance preamplifier and bypass chip capacitors, and is encapsulated in a small TO-46 package. A ball lens cap with AR coating is hermetically sealed to provide an efficient coupling with a single mode fiber. The pigtail type and the LC-ROSA type are available as an option.

Specifications of Pigtail Type and LC ROSA Type
A standard single mode fiber is coupled to a hermetically sealed PD-TIA module. A multimode fiber pigtail is available as an option. The standard LC ROSA provides an efficient coupling with a single mode fiber with a lens.
