A Q&A with Frank Effenberger, vice president of the Fixed Access Network Laboratory at Futurewei Technologies, the US subsidiary of Huawei. Effenberger is also rapporteur of the ITU-T Q2/15 group that standardises optical access.
Q. What are the various ways the industry is considering implementing 100 Gigabit?
FE: The work happening now is to do a 25 gigabit-per-second wavelength, and then multiple wavelengths will be combined in some way to create 50-gigabit or 100-gigabit speed offerings.
