In the integrated wiring system, the rise of optical cables between floors in vertical systems, narrow space applications of communication cabinets in horizontal systems, fiber-to-desktop applications, and communication applications passing through high-pressure inflatable spaces all put forward different requirements for indoor optical cables.
At present, most indoor optical fiber cables use tight-buffered fibers or single-core cables as basic units, reinforced by aramid yarns, and soft optical cables with flame-retardant or non-flammable sheaths. Its advantage is that the tight sleeve is integrated with the optical fiber to provide good mechanical protection, so that the optical fiber exhibits good compression and bending resistance when it is terminated; good flexibility and toughness, and small bending radius; very Good environmental protection improves the service life of the optical fiber.
The tight buffer fiber also has excellent moisture resistance; the tight buffer layer is easily stripped to the fiber core; it is compatible with all standard connectors; it simplifies the termination procedure and reduces the cost of termination. The tight-buffered optical fiber design and flame-retardant or non-flammable sheath make the indoor optical cable fully meet the requirements of indoor safety applications. Therefore, indoor high-performance communication transmission applications generally adopt indoor optical cables with tight-buffered optical fibers.
When conducting integrated wiring, we generally choose two types of optical cables: vertical lifting optical cables and rat-proof optical cables. The vertical lifting optical cable is to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinets on different floors after the optical cable enters the building, which is called "vertical wiring system". At this time, the optical cables are mostly located in the vertical pipes of the vertical shafts between floors.
For this reason, the optical cable needs to withstand greater tensile force; mouse-proof optical cable: single-core or multi-core tight-buffered optical fiber type optical cable protected by stainless steel hose, which has strong resistance to lateral pressure, bending resistance, and tensile strength High and excellent anti-rodent performance. It can be used in occasions where stepping occurs, such as laying under carpets or occasions where limited space requires frequent bending or rodent damage.
