Description

The PDA range of products includes a variety of compact fiber pigtailed devices designed for wide operating temperature, low cost applications such as fiber in the loop. The planar InGaAs photodiodes are manufactured using MOVPE growth technology and give low leakage and high responsivity performance with excellent reliability.

The construction of the devices includes a hermetically sealed photodiode and an actively aligned fiber pigtail and is designed to be compatible with the environmental requirements of the Bellcore TA-NWT-000983 document.

The product range includes a variety of pinout, fiber type, and package mounting bracket

PDA Pigtailed Photodiode Specifications

Absolute Maximum Ratings

Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided that each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
