Abstract
A chassis includes a plurality of continuous wave lasers each operable to emit a continuous wave optical beam at the same power as the other lasers, and a plurality of optical couplers operable to input the continuous wave optical beams of the same power and output a plurality of continuous wave optical beams at different powers. The chassis further includes a plurality of optical assemblies operable to modulate the continuous wave optical beams of different powers into a plurality of modulated optical signals at different powers and couple the modulated optical signals onto different length optical mediums so that lower power ones of the modulated optical signals are coupled to shorter ones of the optical mediums and higher power ones of the modulated optical signals are coupled to longer ones of the optical mediums.
