A 0.5 /spl mu/m SiGe pre-equalizer for 10 Gb/s single-mode fiber optic links

A 10-complex-tap T/2-spaced pre-equalizer, intended to equalize a 10 Gb/s duobinary signal transmitted over 400 km of standard single-mode fiber, is described. Fabricated in 47 GHz f/sub T/ SiGe technology, it operates at clock frequencies up to 13 GHz (limited by test equipment), occupies an area of 3.9/spl times/3.2 mm/sup 2/, and dissipates 3 W from a dual supply of 5 V and 3.3 V.
