The indoor optical cable is reinforced with aramid yarn, and the sheath is a flame-retardant or non-flammable soft optical cable. Its advantage is that the tight sleeve is integrated with the optical fiber to provide good mechanical protection, so that the optical fiber shows good compression and bending resistance when it is terminated; it has good flexibility and small bending radius; good environmental protection improves the use of optical fiber life.
Indoor leather cable
As the transmission medium of integrated wiring system engineering, optical cable has a wider range of applications and continuously meets people's needs for information and communication networks. Due to the special indoor environment, indoor optical cables must meet the toxicity, corrosion and low smoke requirements in the standard, while maintaining very good flame retardancy, mechanical properties and light transmission properties. Let me tell you how optical cables meet the needs of indoor integrated wiring.
In the integrated wiring system, the hoisting of optical cables between floors in the vertical system, the narrow space application of communication cabinets in the horizontal system, the application of optical fiber to the desktop, and the application of communication through overhead. Pressure-filled spaces have different requirements for indoor optical cables. Therefore, extra care must be taken when selecting indoor fiber optic cables.
Indoor optical cable selection skills
At present, most indoor optical cables use tight-buffered optical fibers or single-core optical cables as the basic unit, reinforced with aramid yarn, and the outer sheath is made of flame-retardant or non-flammable flexible optical cables. Its advantage is that the tight sleeve is integrated with the optical fiber to provide good mechanical protection, so that the optical fiber shows good compression and bending resistance when it is terminated; it has good flexibility and small bending radius; good environmental protection improves the use of optical fiber life.
Tight-buffer fiber also has excellent moisture resistance; tight buffer layer is easy to strip to the fiber core; it is compatible with all standard types of connectors; it simplifies the termination procedure and reduces the cost of termination. The tight-buffer fiber design and flame-retardant or non-flammable jacket make the indoor fiber optic cable fully compatible with indoor safety applications. Therefore, in indoor high-performance communication transmission applications, indoor optical cables designed with tight-buffered optical fibers are generally used.
When carrying out integrated wiring, we generally use two kinds of optical cables: vertical lifting optical cables and anti-rat optical cables.
Vertical lifting optical cable: After the optical cable enters the building, it needs to provide the connection between the entrance equipment, the computer room or the computer room and the communication cabinets on different floors, which is called "vertical wiring system". At this time, the optical cables are mostly located in the standpipes of the shafts between floors. For this reason, optical cables need to withstand greater tension.
Anti-rodent optical cable: single-core or multi-core tight-buffered optical cable protected by stainless steel hose, which has the characteristics of strong lateral pressure resistance, bending resistance, high tensile strength, and excellent anti-rat performance. It can be used in situations where footsteps occur, such as under carpet or where space is limited, bending over is common or rodent infestation is a problem.
