Typically, OPGW cables contain single-mode optical fibers with low transmission loss, allowing long-distance transmission at high speeds. The outer appearance of OPGW is similar to aluminium-conductor steel-reinforced cable (ACSR), usually used for shield wires. Prysmian has a built-in multi-step quality assurance programme, which covers the entire production process from cable design and raw materials purchasing, to final inspecti tion for any single project. Prysmian never has a pre-determined answer to a challenge – instead. Single-mode fibre (SMF) provides optimum performance in both the 1310nm and 1550nm wavelength operation ranges (including the 1565 – 1625 nm L-band), with a low dispersion in the 1310nm window. It can be used in all cable constructions and supports long haul, metropolitan, access and premises. Fiberon OPGW is one of the most reliable fiber optic mediums for the telecom service providers, ISPs, Cable TVs, or other organizations who are involved in the transmission of one or more form of voice, data, video, text, messages, conferencing and telemetering kind of things. Installation became. OPGW cable, short for Optical Ground Wire or Optical Fiber Composite Overhead Ground Wire, represents a sophisticated engineering solution that integrates two critical functions into a single overhead cable. At its core, an OPGW cable serves as a traditional ground wire (also known as shield wire. OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current.
