Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers disposed in a covering jacket as the transmission medium and may be used individually or in groups as telecommunication cable assemblies. The optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic sheath, and has no metal such as gold, silver, copper and aluminum, and generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers according to a certain mode to form a cable core, is coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission.
With the implementation of a large number of 'home-wide' engineering projects of users in newly-built cells or old cells, the indoor optical cable is widely used due to the fact that the number of cores is small and the weight is light, but due to the fact that the ultraviolet resistance performance of the optical cable sheath of the type is poor, after long-time wind blowing and sun drying, the outer sheath of the optical cable can age and crack, even is in a powder shape, and the transmission performance of the optical cable is seriously influenced; and the requirement of aerial laying with the span of more than 100m is also provided for the indoor optical cable.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a light-duty district drop optical cable that registers one's residence.
The utility model discloses the technical scheme who adopts as follows:
the light residential entrance drop optical cable comprises a polyethylene outer sheath, a metal reinforcing belt, a water blocking belt and a low-smoke halogen-free flame-retardant sheath material sheath, wherein the water blocking belt is arranged inside the polyethylene outer sheath, the metal reinforcing belt is arranged on two sides of the water blocking belt, the low-smoke halogen-free flame-retardant sheath material sheath is arranged inside the water blocking belt, optical fibers are arranged inside the low-smoke halogen-free flame-retardant sheath material sheath, and the metal reinforcing belt is arranged on two sides of each optical fiber.
Preferably: the polyethylene outer sheath is connected to the water-blocking tape through gluing.
With the arrangement, the polyethylene outer sheath plays a role in protection, and the connection strength is ensured through adhesive connection.
Preferably: the metal reinforcing band is embedded in the polyethylene outer sheath.
So set up, metal reinforcement area plays the reinforcing effect, increases the connection compactness.
Preferably: the low-smoke halogen-free flame-retardant sheath material sheath is filled in the water-blocking tape.
By the arrangement, the water-blocking tape plays a role in protection, and the water-blocking tape and the low-smoke halogen-free flame-retardant sheath material sheath are conveniently stripped.
Preferably: the metal reinforcing belt is embedded in the low-smoke halogen-free flame-retardant sheath material sheath.
So set up, the metal strengthening band plays the reinforcing effect, increases the connection compactness.
Preferably: the optical fiber is filled in the low-smoke halogen-free flame-retardant sheath material sheath.
So set up, optic fibre plays the transmission signal effect, has improved the protection effect of low smoke and zero halogen flame retardant sheath material sheath.
Preferably: the polyethylene outer sheath is made of polyethylene, and the low-smoke halogen-free flame-retardant sheath is made of a low-smoke halogen-free material.
By the arrangement, toxic and corrosive gases generated during combustion of the low-smoke halogen-free material are avoided.
The utility model has the advantages that:
1. a layer of water-blocking tape is coated outside the subunit, so that the water-blocking performance of the optical cable is ensured, and the stripping performance between the subunit and the outer sheath is good;
2. the reinforced steel wires are horizontally arranged on two sides of the subunit to ensure the tensile property of the optical cable, so that the span of laying the optical cable meets the requirements of users;
3. the outer sheath is made of HDPE sheath material with good ultraviolet resistance, so that the service life of the optical cable is ensured.
