Optical Fiber Composite Low Voltage Electric Cable (OPLC)
Optical fiber composite insulated power cable for low voltages (OPLC) is a new type of photoelectric composite cable for low voltage power lines, and has double functions as ordinary low voltage cable and communication cable. The structure of OPLC integrates the fiber and copper wire of transmission and distribution, it uses fiber composite low voltage cable as well as passive optical network technology to achieve fiber to the home (FTTH), undertake the power information collection service of resident users in information intranet, and satisfy the information extranet, multi- network integration service required by intelligent power grid informatization, automation and interactivity.

Product advantages
◆It integrates the fiber and power transmission and distribution cable, avoids the second wiring, and can effectively reduce the cost of construction and network development.
◆Suitable for various business types; strong adaptability; strong expansibility; wide range of product adaptation.
◆Strong mechanical property, such as impact resistance, good pressure resistance, and strong environmental adaptability.
◆Green and extraordinary safety property.
◆Optical unit is compatible with the long working temperature of the power cable.
◆The cost of OPLC is increased by less than 10% of that of traditional low voltage cable, and the cost of FTTH project of OPLC
would be reduced by around 40% of the composite cost of the traditional power cable plus optical cable line project.
