Pigtailed PIN Photodiodes
Technical Data
PDT1X4X
Description
The PDT 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 manufac-
tured using MOVPE growth tech-
nology 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-TSY-000983
document.

PDT 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 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.
