The only optical switching components used in these networks are tunable transmitters and/or receivers.... In PAGE 8: ... In multihop B amp;S networks, data is broadcast on all links, but electronic switches (effectively) provide wavelength conversion on the path from the source to the destination because not all nodes receive all wavelengths. Given that these networks are B amp;S, the only optical switching components present are tunable transmitters/receivers (see Table1 ). Since the components can be tuned on a packet-by-packet or call-by-call basis and the electronic switches can be circuit switches or packet switches, multihop B amp;S networks can be operated in all categories of Fig....
