High Sensitivity OC-3/STM-1 APD

Receivers

SRX03-APD

Product Description

The SRX03-APD is a high sensitivity receiver module designed to ex-

ceed the SONET/SDH optical interface requirements at OC-3/STM-1

(156Mb/s) data rate. Highly reliable InGaAs/InP avalanche photodiode

(APD) is used to cover the entire long wavelength range from 1100nm

to 1600nm.

The receivers feature a low noise GaAs transimpedance IC with AGC ca-

pability to provide an extremely wide dynamic range and high sensitiv-

ity. The APD bias voltage is temperature compensated to ensure stable

operation over the entire operating temperature range. A signal detect

function which indicates loss of optical input is provided. A differential

optical power monitor output is also available.

The SRX03-APD receivers require only a single +5V supply. The data in-

terfaces are differential PECL. The signal detect outputs can be either

PECL or TTL interface.

The SRX03-APD receivers can operate over an operating case temper-

ature range of 0°C to +70°C or -40°C to +85°C. The module is housed

in a 24-pin dual-in-line metal package with a single mode fiber pigtail,

which is terminated with ST, FC or SC connector.
