Description

The family of microwave photodiode receivers are

ideally suited for use in analog fiber-optic communi-

cations. 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

microwave 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.

Description (continued)

In most cases, the basic photodiode module is inte-

grated into a complete receiver, packaged either as a

flange-mount f or extreme environments, or as a plug-in

for integration with Lucent’s System 10000 rack-mount-

able chassis and power supplies. Electronics within

flange-mount and plug-in receivers provide a reverse

bias for the photodiodes and monitor the dc lev el of the

optical input power, thus providing a fully integrated

microwave 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 external load. (See Lucent’s

System Designer’s

Guide to RF and Microwave Fiber Optic

s.)

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