A coaxial DFB laser-diode module with a differential feed for 10-Gb/s Ethernet applications

A TO-"can"-sized coaxial 10-Gb/s 1.3-/spl mu/m DFB laser-diode module with 28% mask margin at 85/spl deg/C was demonstrated. A differential feed provides ease of installation by low return loss (<-7 dB at 10 GHz, lead length 5 mm).
