Optical Fiber Cables for Electric Power System Control

摘要

Results are presented of operational tests on W-type optical fiber cables to be used for electric power system control. The tests were started in May 1976. Transmission loss in operation ranged from 4.6 db/km to 6.2 db/km. Transmission bandwidth ranged from 100 to 400 MHz. Cross-talk attenuation was greater than 60 db. No electromagnetic interference was noted during the course of the test. The mechanical properties of the cable were as good or better than conventional wire cables. Cable splices were made with portable equipment in the field, and the average connection loss was 0.3 db. (ERA citation 04:010176)
