An optical packet Switch uses electric circuits to implement input and output Sections of an
optical Switch that performs packet Switching. Retiming of packet data in the output Section …

Caccuro (57) ABSTRACT An optical packet switch which receives data packets and
switches those data packets in the optical domain without using recirculation devices is …

An optical switching device the size and costs of which are reduced by decreasing the
number of switching elements and which can flexibly accommodate the expansion of the …

(57) ABSTRACT A synchronous packet Switch comprises output modules, input modules,
optical connections and a Switch control unit. The output modules comprise optical receivers …

An optical demultiplexer comprises a clock regenerating circuit for regenerating a clock
signal for each optical signal channel from an optical multiplexed signal. An optical switch …

An optical data stream is converted to electrical signals which are applied to a time-slot
interchanger. The time-slot interchanger recorders the packets or cells of the data stream to …

An apparatus and method for routing optical Signals between a pair of input ports and a pair
of output ports is provided. An optical Switching arrangement adapted to Shift among at least …

BACKGROUND OF THE INVENTION The advent of gigabit-per-second packet networks has
focussed the attention of optical network system designers on the need to provide selected …

An optical switch with a waveguide used as a detector is disclosed. The switch can be used
for circuit or packet switching. The waveguide is used to tap off a fraction of the input signal …

An optical asynchronous transfer mode ATM Switch for recovering the limitation of
processing capacity and per forming large capacity of Switching is disclosed. The ATM …
