Abstract
A fully-engineered 128 channel optical frequency-division-multiplexing distribution system is tested for over 80 days. 128 optical senders, a cold-start automatic multichannel frequency controller, a 144 × 144 waveguide-type star coupler and intra-office interfaces are installed in an NTT standard Hi-PAS cabinet. The error free operation at 622 Mbit/s is successfully achieved with a bit error rate of less than 2.2 × 10-16 for an 85 day period.Keywords
