| Preliminary Data Sheet October 2001 RA2860D 10 Gbits/s APD Receiver Description The RA2860D 10 Gbits/s receiver module incorporates 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 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.
