Telecommunications multipair cable |
摘要 |
A multipair telephone cable (50) has been specifically developed for voice frequency and T1 carrier frequency transmission between cities. The copper wire gauge, dielectric diameter, and insulation expansion are uniquely designed so that this single cable design can be used for either air core or waterproof versions of the cable. Advantageously, both cable versions are compatible with existing carrier and voice frequency electronics. Also, the load coil spacing for voice frequency transmission and the regenerative repeater spacing for carrier transmission coincide in both versions.
