Purpose
- An economical systems is achievable because power transmission and signal transmission are possible simultaneously, by one transmission line.
Features of TCI’s OPGW
- To give the optical fibers adequate heat resistance for use in OPGW, two types of optical fiber bundles, silicon resin type and UV acrylate type, are provided.
