摘要

The applicability of single-mode fibers from the viewpoint of transmitted optical power limitation due to scattering and noise processes is studied. To deal with this applicability of fibers and consequently with lightwave systems performance, several parameters should be taken into consideration. The most important parameters affecting the performance of amplified optical networks are: channel frequency separation, total channel numbers, the maximum allowable signal power, the maximum transmission length, and the receiver sensitivity degradation. The effects of amplified spontaneous emission (ASE) noise, avalanche photodiode (APD) noise, thermal noise, and interference (crosstalk) for optical code division multiple access direct detection (OCDMA/DD) are examined. One such scheme is an optical orthogonal code division multiple access (OOCDMA) system.
