Paper Abstract

A novel solution for all-optical packets buffering in OPS nodes is proposed. Variable delays are performed by exploiting a low-loss optically controlled fiber-based loop configuration. XGM in SOAs allows polarization and wavelength independent operation in the whole C-band. A packet delay resolution of 5 μs is obtained as well as a storage time of 50 μs with moderate signal degradation. Performances are evaluated in terms of bit error rate measurements for 10 Gb/s NRZ data payload, providing an OSNR penalty lower than 3 dB after 10 circulations. The proposed solution is particularly attractive in slotted OPS nodes architectures where packet contention would be managed entirely in the optical domain.
