摘要:
There is provided a reconfigurable optical modulator comprising a light source and a splitter operative to receive an input signal from the light source and to split the input signal into a plurality of split signals. The optical modulator comprises a plurality of optical amplifiers, each being operative to receive one of the plurality of split signals as an input and to act as a switch having a first state where the split signal is blocked and a second state where the split signal is amplified. The optical modulator comprises a plurality of modulators, each being operative to receive an amplified split signal from one of the plurality of optical amplifiers and to modulate the amplified split signal into a modulated signal. The optical modulator comprises an optical combiner operative to combine a plurality of modulated signals produced by the plurality of modulators to thereby produce a modulated output signal.

A headphone includes a pair of right and left headphone units, a resilient band formed substantially into a U shape to be mounted on a human head, and a pair of arm members. Each of the arm members is rotatably coupled via a pivot joint to an end part of the band and supporting one the headphone units. Each of the pivot joints includes a detent hinge for locking into a plurality of rotational positions an arm member relatively to the corresponding end part of the band.

Presented is a system and method for distributing a network application across a plurality of geographically dispersed network sites. The system comprises a plurality of network sites connected by a shared network and interconnected by a dedicated non-blocking communication network. The system can use different interconnecting network topologies based on the number of sites to be interconnected. The method balances the network application load and resources across the interconnected network sites based on a distribution policy implemented without burdening the shared network. The method provides redundancy capabilities by detecting the loss of a network site and redistributing the network application load to the remaining network sites.

An optical patch unit is adapted for mounting in or on an optical equipment rack and facilitates a migration from one optical shuffle box or topology to another. The optical patch unit simplifies the replacement of an optical shuffle box, in some cases allowing a phased migration that minimizes system down-time. The optical patch units described herein include passive optical patch panels. Chassis card and optical shuffle connections are terminated at the passive optical patch panel, making it possible to simplify the cabling between the chassis cards and the optical shuffle box. Once installed, chassis card cables do not need to be manipulated at all during subsequent optical shuffle maintenance procedures. Other optical patch units described herein include active optical patch units, which make the migration process less dependent on human intervention and can further reduce system down-time.

Wavelength-based optical power provisioning is provided by multiplexing a plurality of continuous wave light beams at different wavelengths onto a single optical fiber as a multiplexed light source and demultiplexing the multiplexed light source based on wavelength at a photonic unit coupled to the optical fiber to recover the continuous wave light beams. The recovered continuous wave light beams are split into a plurality of light beams by the photonic unit, each light beam having the same wavelength and the same or lower power as one of the recovered continuous wave light beams so that at least one of the light beams generated by the photonic unit has a higher power than the other light beams generated by the photonic unit.

摘要:
Systems and methods according to these exemplary embodiments provide for optical interconnection using a combination of an arrayed waveguide grating router (AWGr) and optical crossbar. Optical wavelengths can be flexibly routed from an input port to one or more output ports. Scaling of the system is easily accommodated.
