Id. Phillips et al., 100Gbit/s optical clock recovery using electrical phaselocked loop consisting of commercially available components, ELECTR LETT, 36(7), 2000, pp. 650-652
Polarisation and wavelength insensitive 100Gbit/s optical clock recovery us
ing an electrical phaselocked loop consisting entirely of commercially avai
lable components is demonstrated. The system exhibits excellent long-term s
tability, with a timing jitter of similar to 250fs.
