Filed:

Apr 22, 2021

Appl. No.:

17/237966

Inventors:

- Meiningen OT Dreissigacker, DE

Sorin Tibuleac - Johns Creek GA, US

International Classification:

H04J 14/02
H04B 10/079

Abstract:

A method for providing a maximum channel capacity per optical channel in an optical wavelength division multiplexing, WDM, transmission system is described. The WDM transmission system includes transceivers using multiple optical channels in a WDM channel grid to transport optical signals modulated with a modulation format with a signal symbol rate, SR, via an optical transmission link, OTL, along an optical path from a transmitting transceiver to a receiving transceiver. A channel capacity of the optical channel is maximized while a calculated channel margin, CM, is maintained above a preset minimal channel margin value.

Abstract:

A method for determining a maximum transmission capacity, TCAP-OL, of an optical link, OL, within an optical network includes loading an optical transmission spectrum of the optical link, OL, being partially occupied by at least one data traffic carrying channel, CH, with amplified spontaneous emission, ASE, noise spectrally shaped such that the transmission performance of the optical transmission spectrum fully occupied with data traffic carrying channels, CHs, is matched. The method further includes determining the maximum transmission capacity, TCAP-OL, of the optical link, OL, on the basis of measured link data transported through the optical link, OL, via the at least one data traffic carrying channel, CH.

Abstract:

A method for establishing bidirectional communication links includes: supplying, to at least two optical transceiver modules at each side of at least two optical paths, a multiplexed optical CW signal comprising at least two optical CW signals having the same differing wavelengths, and modulating the multiplexed optical CW signal according to modulation signals; creating, at each side of the optical paths, at least two first and second optical transmit signals by optically filtering the modulated optical signals so that only a single wavelength remains, and routing pairs of a first and second optical transmit signal to the optical paths, wherein the optical transmit signals of each pair have differing wavelengths and wherein the optical transmit signals transmitted in the same direction over the same optical paths have differing wavelengths; receiving each optical transmit signals at a dedicated optical transceiver module by mixing it with the multiplexed optical CW signal.
