| PT-12B * PIN/TIA receiver * 62.5 m multimode fiber input with SC or FC Product Bulletin (Preliminary) * April 2004 * High data rate, up to 12.5 Gb/s * Broad wavelength range, 750-1650 nm * High sensitivity, -15 dBm @ 850 nm * SMA or GPO output connector The PT-12B is a single-output receiver module for 12.5 Gb/s short wavelength applications. It couples a high responsivity (0.95 A/W), front-illuminated PIN photodiode, usable from 750 nm to 1650 nm, with an internal transimpedance gain stage of 475 V/A. This combination produces a receiver with a 9.5 GHz bandwidth and a conversion gain of 450 V/W at 1310 nm. The single-coaxial output module is available with either an SMA or GPO output connector in a compact, 8-pin butterfly package with multimode fiber input.
