Detailed floor plan for a telecommunications equipment room labeled “UPS KANAL” with dimensions of 339 x 506 meters. The layout shows the arrangement of critical telecommunications infrastructure including existing and new ODF (Optical Distribution Frame) cabinets, DSLAM equipment, metal cable trays, floor cable channels, and fiber optic connections. Key components include HUBER+SUHNER LSFH 96×9/125 fiber optic cables (40m length) identified as 31_10404_1 and 31_10404_2, interconnecting new and existing equipment. The drawing indicates equipment zones for AKTIVA, GRO (main distribution panel), batteries, power supply units, and colocation space. A clear legend differentiates between existing equipment, new ODF cabinets, existing metal shelving/trays, and in-floor cable channels. This technical layout plan was developed for Hrvatski Telekom’s FTTH Zagreb Kanal Sigečica infrastructure project.
