The AT-2.5SFB/17LP/AC/MM/FC is a -33 dBm sensitivity, differential-output receiver module for transmission system receive applications up to 3.2 Gb/s. It couples a high responsivity (0.7 A/W @ M=1), front-illuminated APD photodiode, usable from 1250 nm to 1650 nm, with a transimpedance gain stage of 4400 V/A differential. This combination produces a receiver with a 2.5 GHz bandwidth and AC conversion gain of over 14,000 V/W differential. The differential-output module is offered in a 17-pin MSA package with single-mode fiber input and the output is available either AC- or DC-coupled. The receiver meets Telcordia GR-468 qualification standards.
