Embodiment Construction

[0018] As a non-limiting example, figure 1 One embodiment of a chassis 100 for use in an ICT system is illustrated. Chassis 100 includes line cards 102 having discrete modules 104 enabled through optical interfaces 106 . Modules 104 may be optically interconnected to establish ultra-high speed data exchange links. The provision of light sources for the optical channels 108 on the line cards 102 is enabled by a laser array 110 included in the chassis 100 . Each laser array 110 operates as a light source and includes a plurality of continuous wave (CW) lasers and a WDM multiplexer operable to multiplex CW beams of different wavelengths generated by the lasers onto a single optical fiber as Multiplexed light sources ( figure 2 step 200). Each line card 102 has an optical frontplane 114 equipped with optical I / O (input / output) ports 116, 118 for aggregated optical channels. Each line card 102 is plugged into the electrical backplane 120 to access the backplane low speed cont...

Abstract

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.

Description

technical field [0001] The present invention relates generally to information and communication technology systems and more particularly to wavelength-based optical power provision for information and communication technology systems. Background technique [0002] A chassis for conventional information and communication technology (ICT) systems includes line cards, usually with discrete modules enabled through optical interfaces. The modules can be optically interconnected to create ultra-high-speed data exchange links. The provision of light sources for the optical channels on the line cards is enabled via the optical front panel by an external laser array. The front panel is equipped with optical I / O (input / output) ports for aggregated optical channels. Each line card is plugged into the electrical backplane to access the backplane low-speed control unit, power management and power supply. High speed data transmission is enabled via the optical front plane. Optical I / O...
