Jacketed fibres

Structure and characteristics

Structure: usually from inside to outside including the core, cladding, coating and sheath. Core is the core of optical signal transmission; cladding is used to limit the light transmission within the core; coating layer plays a role in protecting the optical fibre; sheath is the outermost protective structure, generally made of plastic, rubber and other materials, with a certain degree of strength and flexibility.

Product features

High mechanical strength: the sheath can withstand a certain amount of tension, pressure and impact, reducing mechanical damage to the optical fibre in the process of laying and use, improving the reliability and service life of the optical fibre. For example, in overhead or direct burial laying, the sheath can protect the optical fibre from wind, sun, rain and soil pressure and other factors.

Waterproof and moisture-proof: With good sealing performance, it can effectively prevent moisture from intruding into the optical fibre, avoiding performance degradation or damage caused by moisture. This is particularly important for the use of optical fibres in humid environments or underwater, such as undersea communication cables need to have a highly waterproof sheath.

Corrosion resistance: the chemical substances have a certain resistance, can maintain stable performance in different chemical environments, not acid and alkali and other corrosive substances erosion. Therefore, sheathed optical fibre can be used in some harsh industrial environments.

Application Scenario

Communication field: widely used in long-distance communication, local network, access network, etc., such as backbone communication network between cities, broadband access network in small areas, etc., which can ensure the stable transmission of optical signals and reduce the influence of external factors on the quality of communication.

Industrial field: In industrial automation control system, electric power system and other scenarios, it is used to connect various devices and sensors and transmit control signals and data. Its high reliability and anti-interference can ensure the stable operation of industrial production process.

Special environment: It is suitable for some special environments, such as mines, tunnels, chemical workshops and so on. In these environments, sheathed optical fibres can resist the erosion of dust, water vapour, chemical gases and other harmful substances to ensure the normal communication and data transmission.
