The 1319MR high-speed APD receiver consists of a wideband linear preamp followed by a limiting
amplifier buffer stage. It is designed for use in singlemode, high-speed applications at the SONET OC-48
and STM-16 data rate of 2488.32 Mbits/s. The receiver is built with an APD photodetector. At 2.5 Gbits/s, the typical room temperature receiver sensitivity measured at 3 x 10–11 bit-error rate is –34 dBm. The operating case temperature range for the APD receiver is 0 °C to 60 °C. The receiver is manufactured in a 14-pin butterfly lead package with a single-mode optical fiber pigtail. The fiber in the 1319M-Type is internally beveled for low optical return loss.
