Apparatus and methodology providing, a portable enclosed space in an outdoors setting, the space being free from environmentally-induced distractions. A technician can perform a mechanical or fusion splice on an optical fiber inside the space. Splicing or fusing miniscule optical fibers is challenging out of doors, particularly when distracted b wind, rain, snow, sun-glare, bugs, animals, etc. A tent is supported by a “spine” support structure modularly constructed by the technician in the outdoors location where an optical fiber operation shall take place. A splice-tray is affixed to the spine, the tray height being adjustable to accommodate that technician and provide an approximately horizontal work surface. The tent can be used on soft ground, hard pavement, leaning against utility poles or further supported by attachment to overhead cables. The technician can perform delicate operations on optical cables inside the tent with outside distractions mitigated.

A system includes an optical line terminal (OLT) that includes an OLT transmitter. The OLT transmitter includes one or more fixed wavelength optical sources that generate an optical signal at a first wavelength, and an optical waveguide that transmits the optical signal at the first wavelength in an optical network.

A method is provided for distributing quantum cryptographic keys. The method includes receiving a first quantum signal from an initial quantum key generating transmitter. Following correspondence with the initial quantum key generating transmitter, a first quantum key is generated. A second quantum signal is transmitted to a recipient quantum key generating transmitter. Following correspondence with the recipient quantum key generating receiver, a second quantum key is generated. The first quantum key is encoded using the second quantum key. The encoded first quantum key is transmitted to the recipient quantum key generating receiver using the second quantum key.

One embodiment provides an apparatus for material deposition. The apparatus includes a reaction chamber, and a pair of susceptors. Each susceptor has a front side mounting substrates and a back side. The front sides of the vertically positioned susceptors face each other, and the vertical edges of the susceptors are in contact with each other. The apparatus also includes a number of gas nozzles for injecting reaction gases. The gas flow directions inside the chamber can be alternated by controlling the gas nozzles. The gas nozzles are configured to inject a small amount of purge gas including at least one of: HCl, SiCl4, and H2 when the gas nozzles are not injecting reaction gas. The apparatus includes a number of heating units situated outside the reaction chamber. The heating units are arranged in such a way that they radiate heat energy directly to the back sides of the susceptors.

Apparatus and methodology for discharging static electricity from a vehicle which uses a discharge mechanism that does not contact the roadway (Earth) when the vehicle is in forward motion to reduce, or completely avoid, frictional wear on the discharge mechanism. In one embodiment, the displacement between the discharge mechanism and the roadway is obtained by way of wind force generated by the motion of the vehicle itself. A properly oriented and hinged windscreen attached to the conductive path discharge mechanism can be used for this purpose. Other embodiments including magnetically controlled lifting and holding devices can be used.

An optical device may include first and second male connectors and a patch panel that includes through holes for interconnecting the first male connectors and the second male connectors. The optical device may also include a patch panel cleaner to automatically clean the through holes of the patch panel, and a connector cleaner to automatically clean the first male connectors or the second male connectors.
摘要:
A device determines a bandwidth demand for traffic provided between a line terminal (LT) and multiple optical network terminals (ONTs), and dynamically tunes, based on the determined bandwidth demand, one or more tunable filters provided in the LT and the multiple ONTs to one of balance the traffic, protect the traffic, or increase available bandwidth for the traffic.
摘要:
A method for implementing a truly hitless tunable filter for use in adding and/or dropping channels in a wavelength division multiplexed (WDM) network is disclosed. An exemplary method for filtering an optical signal may include providing a composite optical signal having several wavelengths including a first wavelength, a second wavelength and other wavelengths. The method may include passing the first wavelength through a filter and reflecting the second wavelength and the other wavelengths with the filter. The method may include making the first wavelength available to a drop port, and making the second wavelength and the other wavelengths available to an output port.
