System aspects of application of optical cables with multichannel fibers in perspective telecommunication networks are considered. The multichannel fibers efficiency with standard and increased diameter of optical sheath is estimated. Numerical values of spatial and spectral efficiency are given. The efficiency and quality of the cable are compared, and calculation of the values of the factors for ensuring the required quality is carried out.
