Description
The RA2860D 10 Gbits/s receiver module incorpo-
rates a high-gain bandwidth APD and a preamplifier
to provide exceptional dynamic range, including very
high sensitivity and excellent overload.
Agere Systems Inc. offers several 1R and 2R high-
speed 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 abso-
lute 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
* At high optical power; current must be limited.
Electrical/Optical Characteristics
* External dc block required on RF output.
