Abstract :
The feasibility of transmitting 1 55-Mb/s SONET/ATM signals over 131 m of unshielded 24 AWG single twisted pair copper cable and 213 m of shielded 22 AWG twisted pair cable with bit error ratios of less than 10 -13 is shown. The transmission performance of the single-pair unshielded cable is compared to that of category 3 and 5 four-pair unshielded twisted pair cables and category 1 two-pair shielded twisted pair cables. The merits of two-level encoding and three-level encoding are examined. The three-level encoding has a noise margin that is 6 dB greater than the two-level encoding. The results indicate that it may be feasible to employ copper drops for distribution of SONET/ATM asynchronous optical network/asynchronous transfer mode) signals to businesses and residences and for a local area network within an office complex
