Systems and methods are described for an optiplex.

Suitable for Optical Orthogonal Frequency Division Multiplecing (OFDM) and Coherent WDM multi-carrier systems.

This architecture can be used as a programmable demultiplexer to implement reconfigurable wavelength-division-multiplexed (WDM) optical systems.

The modulated laser output may then be optically multiplexed to produce an aggregate optical signal including multiple channel wavelengths.

A multiplex means (102) of the optical multiplex device (91) multiplexes data (data E1 and the like), which are outputted from devices, with frame data (FD).

Other fields of application include: optical analogue/digital converters, optical time domain multiplexing (OTDM) and optical systems based on code multiplexing (CDMA).

Well versed with both wavelength division multiplexing (WDM, CWDM, DWDM).

An optical wavelength division multiplexing system, method and branching unit.

The object of the invention is to provide an optical wavelength multiplexing transmission apparatus which can transmit an optical signal from one transmission/reception unit to a plurality of transmission/reception units.

For wavelength division multiplexing, the system has a map strength preferably comprised between 4 and 8.

In one example, the output pulse sequence is used to control an optical switch to provide an OTDM programmable multiplexer using optical signals.

Disclosed is an arrayed waveguide grating optical division multiplexing module capable of obtaining low noise levels even when temperatures change.

The optical multiplexing of the different optical paths in accordance with the present invention enables to cover a large angular field, besides the elementary fields.
