Description
The family of wideband photodiode receivers are ideally suited for use in analog fiber-optic communications. With their wide bandwidth and flat response,
these devices are used in a wide array of applications, including antenna remoting, timing and reference signal distribution, measurement, delay lines,
and two-way communications.
Several packaging styles are available for these
wideband photodiodes. The most basic package, the
photodiode module, contains the photodiode chip,
optical fiber pigtail, and impedance-matched electrical connections in a hermetically sealed unit. Of particular note is the high optical return loss, which
enables high-quality noise performance for sensitive
optical links.

Wideband Photodiode Receivers
Description (continued)
for integration with Agere Systems Inc.’s System 10000
rack-mountable chassis and power supplies. Electronics within flange-mount and plug-in receivers provide a
reverse bias for the photodiodes and monitor the dc
level of the optical input power, thus providing a fully
integrated wideband product.
In most cases, the basic photodiode module is integrated into a complete receiver, packaged either as a
flange-mount for extreme environments, or as a plug-in
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
