INTEGRATING METHOD BETWEEN CABLE TELEVISION BROADCAST OPTICAL FIBER SYSTEM AND OPTICAL FIBER LAN SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide the integration method between a cable television broadcast optical fiber system and an optical fiber LAN system where a large data communication channel capacity is obtained and security of a data communication channel is assured. SOLUTION: A television broadcast optical fiber 11 and a LAN optical fiber 12 in the same optical fiber cable 10 are used separately. In the process of a system construction, the optical fiber cable 10 is installed to build in simultaneously the cable television broadcast optical fiber system 11 and the optical fiber LAN system 12. However, in the case that a transmission destination of a cable television broadcast signal and that of an optical fiber LAN communication signal are different, the optical fiber cable 10 only at the part where the optical cable installation route is s hared is unified.
