R2860D Digital Receiver OC-192/STM-64
Description
The R2860D 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
10 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

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.
