Average level of each length of cable: L=[(S1+S2)/2]+L1+L2 l: average length of cable; L1: MDF cable allowance; L2: other allowances S1: minimum horizontal cable length; S2: maximum horizontal length of cable; Office building of information: a minimum of 26 meters, the longest was 92 meters, L=[(28+92)/2]+2.5+1=62.5 m; Total length of 62.5 m x792 = 49500-meter in each box (KFT) by 300 meters per carton; The twisted-pair cable box you want = 49500 ? 300=165 (KFT); losses not included, each about 15 meters.
