SHIELDED COMBINED Symmetric four pair category with 7 shielded optical modules OPEN TYPE

摘要

Shielded combined symmetrical four pair 7 categories with shielded optically open type modules containing core in the polymeric insulation of the outer polymer sheath, characterized in that each pair placed in metal band metal outward with overlapping edges throughout the length of the cable, and between the shielded pairs are placed shielded open optical modules with overlapping edges along the entire length of the cable metal outwardly from the placement in their design cruciform strength member, providing rigidity open the module and having in each window of the module optical fiber, the symmetric shielded pairs and open modules one by coils twisted around a shielded central optical module gated metal outwardly also amplified cross force element with optical fibers in each of the module window, wherein all the screens symmetric pairs and optical modules open and closed formed of a metal-metal belt outward, providing contact with drain conductor and imposed on top of helix shielded symmetric pairs and open the optical module bimetallic strip, the metal braid and an outer polymer sheath.
