OPGW Design & Standards


(Optical Ground Wire) is a dual functioning cable, as it is commonly referred to, serves as a ground wire and a telecommunications link at the same time, as overhead optical fiber cable. We are offering according to SEC/NGSA SDMS/TMSS Standard.

Design & Construction

Stainless steel tube OPGW: stainless steel tube is hermetically sealed by seamless welding. The tube is filled with water resistant gel. This tube provides complete protection to the fibers from longitudinal and lateral water/moisture ingress. The interstices in between the stainless steel tube and the metallic wires are filled with anti-corrosive grease for protection from corrosion.

It has made such many new technical records as large cross-section, big cores, large capacity, long span, ice resistance, sand, lighting resistance and ultra-high voltage.

Reference Standards

The products meet international standards such as IEC60794 and IEEE1138, and can be manufactured according to customers’ requirements / standards like NBR, BS, TMSS, and SDMS & so on.
