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
options, designed to match the
majority of offerings in the
marketplace. If the specific
arrangement or performance you
require is not listed, please
contact Hewlett-Packard. High
flexible design and manufacturing
processes allow both physical and
electro-optic customization to
suit your needs.

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.
