Features
The optical fiber composite low voltage cable (OPLC) integrates optical cable and power cable and transfers power and information at the time. The optical fiber composite low voltage cable (OPLC) combines communication optical fiber cable and electric power cable and realizes the dual functions of terminal power supply and information transmission. This cable uses transmission medium of photoelectric integration to avoid secondary wiring and save construction cost. This power cable make full use of low voltage cables and resources of cable lines which are laid to the home. The part of power and optical cable remain relatively independent to make the installation easy when the introduction, extraction and connection. The power cable has small outer diameter and light weight, so it can save resources of pipelines space. This product has large range of operating temperature and construction temperature.
