AGERE R2860F023, R2860F040 Datasheet

R2860F Digital Receiver OC-192/STM-64

Description

The R2860F 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
line of high-speed receiver products, please visit the

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.
