Fiberoptisk transmissionssystem med forbedret samlet optisk indgangseffekt |
摘要 |
The invention refers to an optical fiber transmission system, comprising a transmitter terminal (10) launching an optical signal into a fiber line, whuch is guiding the signal to a receiver terminal on the far end of the fiber line. The signal composed of a multitude of bit-patterns at different wavelength channels within a given total bandwidth of wavelengths. In order to increase the optical power budget of the system, the fiber line consists, in its first section, of at least two branches (12a, 12b). The transmitter (10) launches a separate part of the optical signal into each one of the branches (12a, 12b). Each part of the signal is composed of a sub-multitude of the bit-patterns at neighbouring wavelength channels within non-overlapping bandwidth domains. The parts of the signal are multiplexed together into one unique fiber (14) by means of a multiplexer station (13) not closer to said transmitter terminal (10), than the sum of the total optical powers guided by each of the branches (12a, 12b) plus the losses due to the multiplexing has decreased below the total optical power, that is associated with a maximum optical power budget in said unique fiber (14) guiding the full bandwidth of wavelengths. <IMAGE> |
