Description

The family of wideband photodiode receivers are ide-

ally suited for use in analog fiber-optic communica-

tions. With their wide bandwidth and flat response,

these devices are used in a wide array of applica-

tions, including antenna remoting, timing and refer-

ence 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 electri-

cal connections in a hermetically sealed unit. Of par-

ticular note is the high optical return loss, which

enables high-quality noise performance for sensitive

optical links.

Description (continued)

In most cases, the basic photodiode module is inte-

grated into a complete receiver, packaged either as a

flange-mount for e xtreme environments, or as a plug-in

f or integration with Agere Systems Inc.’s System 10000

rack -mountable chassis and power supplies. Electron-

ics within flange-mount and plug-in receivers provide a

rev erse bias for the photodiodes and monitor the dc

level of the optical input power, thus providing a fully

integrated wideband product.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute 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.

Characteristics

1. Specified for <2 mW optical power, <50% modulation depth.

2. The photodiode RF current splits evenly between the internal matching resistor and the ex ternal load. (See Agere Systems’

System

Designer’s Guide to RF and Wideband Fiber Optic

s.)

3. Optical return loss specified for FC-APC connectors or fusion splices only. Other connection methods can degrade optical return loss.
