Abstract
The necessity of tightening requirements for the maximum attenuation created by standard fiber optic connectors in the data center cabling system is justified. The expediency of introducing VSFF group connectors in this area is demonstrated, and an assessment of the maximum attenuation they introduce is performed. The need to expand the component composition of the cabling system by introducing adapter cassettes designed for installation in standard cassette and slot shelves is noted.
