Ns. Moon et K. Kikuchi, N x N optical cross-connect based on tunable fibre Bragg gratings with high channel scalability, ELECTR LETT, 37(23), 2001, pp. 1402-1404
A highly channel-scalable N x N optical cross-connect (OXC) based on tunabl
e fibre Bragg gratings is proposed. The channel scalability of the proposed
OXC is owing to cascadability of individual routing modules which perform
routing only for specified wavelength channels. The routing function of a 3
x 3 routing block of the proposed OXC using four OC-192 channels with a ch
annel spacing of 0.8 nm, is demonstrated, as is the upgradability of the nu
mber of ports and wavelength channels.
