1.3-$\mu$ m VCSEL Transmission Performance up to 12.5 Gb/s for Metro Access Networks

We experimentally demonstrate 1.33-mum vertical-cavity surface-emitting laser characterization (linewidth and chirp measurements) and very good propagation performances at multi-Gb/s in single-mode-fiber transmission. Error-free measurements are presented both for 10.3 Gb/s over 40 km and for 12.5 Gb/s over 20 km at different operating temperatures.
