Data Sheet June 2001 Wideband Photodiode Receivers Features ■ Wide-band analog signal reception ■ Single-mode fiber pigtail ■ High optical return loss ■ Up to 20 GHz bandwidth ■ 1310 nm and 1550 nm sensitivity Applications ■ Antenna remoting ■ Cellular and PCS networks ■ Military triband communications ■ TT and C Description The family of wideband photodiode receivers are ideally suited for use in analog fiber-optic communications. With their wide bandwidth and flat response, these devices are used in a wide array of applications, including antenna remoting, timing and reference signal distribution, measurement, delay lines, and two-way communications. Several packaging styles are available for these wideband photodiodes. The most basic package, the photodiode module, contains the photodiode chip, optical fiber pigtail, and impedance-matched electrical connections in a hermetically sealed unit. Of particular note is the high optical return loss, which enables high-quality noise performance for sensitive optical links. Data Sheet June 2001 Wideband Photodiode Receivers Description (continued) for integration with Agere Systems Inc.’s System 10000 rack-mountable chassis and power supplies. Electronics within flange-mount and plug-in receivers provide a reverse bias for the photodiodes and monitor the dc level of the optical input power, thus providing a fully integrated wideband product. In most cases, the basic photodiode module is integrated into a complete receiver, packaged either as a flange-mount for extreme environments, or as a plug-in 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.
