R2860G Digital Receiver OC-192/STM-64
Description
The R2860G receiver module incorporates a highspeed planar PIN diode and an HBT preamplifier to provide exceptionally high linearity. The receiver is designed to provide very clean pulse response at 12.5 Gbits/s that results in high-quality eye patterns (see Figure 1). Agere Systems Inc. offers several 1R and 2R highspeed receiver components for 10 Gbits/s and 12.5 Gbits/s applications. APD and PIN versions are available in a 6-pin hermetic package with coaxial output. In addition, Agere Systems also offers a PIN receiver with coplanar waveguide in a multisource agreement form-factor or a smaller, space sensitive package. For more information about the complete line of high-speed receiver products, please visit the Agere Systems' website at www.agere.com/opto.

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.
