Mux/Demux Queues, FIFO Queues, and Their Construction by Fiber Memories

Timeslot interchanging by efficient optical switches

“…Multiple FSBs can be serially connected into a fibre memory for large‐scale optical switching. In the existing literature, FSBs and fibre memories have been adapted for various application devices in the time domain, including TSI [1], multiplexer [2, 3], priority queue [4–6], first‐in‐first‐out queue [7–9], last‐in‐first‐out queue [8], and non‐overtaking/flexible delay line [10].…”

Emulation of multistage interconnection networks by fibre memory

“…A 'fibre-switch block' consists of an n × n optical switch together with n − 1 delay lines, each connecting a pair of I/O. A serial connection of fibre-switch blocks will be called a 'fibre memory', which has been adapted into various application devices including 'timeslot interchanger' (TSI) [1], 'multiplexer' [2,3], 'FIFO queue' [4,5], 'priority queue' [6,7], 'last-in-first-out (LIFO) queue' [8], 'non-overtaking delay line' [9], 'flexible delay line' [9] and so on.…”
