High Sensitivity OC-12/STM-4 APD

Receivers

SRX12-APD

The SRX12-APD is a high sensitivity receiver module designed to ex-

ceed the SONET/SDH optical interface requirements at OC-12/STM-4

(622Mb/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 SRX12-APD receivers require only a single +5V supply. The data in-

terface signals are differential PECL. The signal detect outputs can have

either PECL or TTL interface.

The SRX12-APD receivers can operate over an operating case tempera-

ture range of 0°C to +70°C (“H”option) or -40°C to +85°C (“I”option). 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.
