R2860A Digital Receiver OC-192/STM-64
Description
The R2860A receiver module incorporates a highspeed planar PIN diode and a GaAs PHEMT preamplifier to provide exceptionally high performance. The
unit provides high bandwidth and sensitivity to operate with long, dispersive fibers, plus wide dynamic
range for operation over a variety of loss budgets.
High transimpedance coupled with a nonquantizing
limiting buffer output provides high gain while limiting
the maximum output signal swing, thereby simplifying
the interface to subsequent stages.

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

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.
