摘要:
A method and a device for adjusting a laser in an optical network. At least one alive message is transmitted from a first optical component towards a second optical component. A confirmation message is transmitted from the second optical component to the first optical component determining the wavelength of the laser to be used based on the alive message received by the second optical component. Furthermore, an optical communication system is provided with an optical element.
摘要:
An optical network has an optical line termination coupled to a backbone network, in particular to an optical long haul network and a local exchange coupled to an optical access network. The local exchange provides an optical connection between an optical network unit of a tree topology and the optical line termination, which is part of a ring topology. There is also described a method for processing data in such an optical network.
摘要:
Bidirectional data signals are exchanged between a central unit and a plurality of network terminals. The optical carrier frequencies of the downstream and upstream signals are chosen so that reflections do not interfere with the selected signal at the optical network unit and not with the received upstream signals at the central unit. The optical network units select their associated downstream signal and generate an associated upstream signal.

A method and a device are provided for adjusting a tunable laser of an optical network element. A wavelength of the tunable laser is adjusted by varying a current driving the tunable laser. The wavelength of the tunable laser is adjusted by varying a temperature of the tunable laser or at least a portion thereof relative to an environmental temperature.
摘要:
A method and a device for data processing in an optical network element are suggested, wherein the optical network element changes between a low-speed mode and a high-speed mode of data transmission. In this manner, the optical network element has efficient power savings because it can effectively operate in the low-speed mode which requires less power consumption.
