Product Bulletin (Preliminary) 鈥?April 2004
鈥?High data rate, up to 12.5 Gb/s
鈥?Broad wavelength range, 750鈥?650 nm
鈥?High sensitivity, -15 dBm @ 850 nm
鈥?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 photo-
diode, 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.
