How to Choose the Right Indoor Fiber Optic Cable?

Blog Article

Due to the special environment of indoor applications, indoor fiber optic cable must meet the requirements of international standards for toxicity, corrosiveness and low smoke. While maintaining very good flame retardancy, mechanical properties and optical transmission characteristics. The rise of fiber optic cables between floors in vertical systems, narrow space applications in communication cabinets in horizontal systems, fiber-to-desktop applications, and communication applications that fill space with high-pressure air all put forward different requirements for indoor optical cables. How to choose the right optical cable to meet the needs of different indoor applications?

Tightly Buffered Optical Cable- One Choice for Indoor Fiber Optic Cable

At present, indoor fiber cable use tightly buffered optical fibers or single-core cables as basic units. Which reinforced by aramid yarns, and soft optical fiber cables with flame retardant or non-flammable sheaths.

Tightly buffered optical fibers are combined with optical fibers to provide good mechanical protection. So that the optical fibers show good compression resistance and bending resistance when terminated. Tightly buffered optical fibers are easy to manage and protect, which improves the service life of optical fibers. Tightly buffered fibers have good moisture resistance. And the tight buffer layer can easily stripped to the fiber core. Tightly buffered optical fibers are compatible with all standard connectors. This operation simplifies the termination procedure and reduces the termination cost.

Compared with the loose tube cable design, the loose tube cable uses jell to buffer and moisture-proof the optical fiber. And jell is not fire-resistant. This is far from meeting the indoor fire safety requirements. Moreover, the flame spreads along the optical fiber cable. So that the damage to the optical fiber cable extends to the depth of the wall and deep into the pipe. During the installation process, a large amount of cleaning materials required. And a lot of cleaning time is spent on jell. At the same time, it is necessary to use splicing means, which greatly increases the material cost. The design of the tight buffered optical fiber indoor optical cable and the flame retardant or non-flammable sheath make the indoor fiber optic cable fully meet the requirements of indoor safety applications.

The outer protective materials used for indoor optical cables are PE, PVC, polyurethane, LSZH (low smoke zero halogen) materials, flame retardant LSZH, etc. Indoor optical fiber cables with different external protective materials can used in environments with different requirements. Therefore, indoor high-performance communication transmission applications generally use indoor optical cables with tight buffered optical fiber design.

Vertically rising fiber cable (riser) – One Choice for Indoor Fiber Optic Cable

After the optical cable enters the building, it is necessary to provide the connection between the entrance equipment. The machine room or the machine room and the communication cabinets on different floors. Which called “vertical wiring system”. At this time, the wiring fiber optic cable is mostly located in the riser in the shaft between the floors. Therefore, the optical cable needs to withstand greater tension (maximum deadweight).

Single-core, dual-core interconnection indoor optical cable – One Choice for Indoor Fiber Cable

Tight buffered single core, tight buffered 2 core, tight buffered 2 core to 24 core circular structure indoor optical cable due to the use of tight buffer structure with very good flexibility and high load-bearing aramid yarn around the tight sleeve optical fiber. The optical cable structure is small in size, good in flexibility, can withstand a small bending radius, and has no inventory traces. Indoor fiber optic cables are ideal for applications such as interconnecting fiber optic cables to workstations, plug-in wiring, fiber pigtails, jumpers in communication cabinets, communication cabinets to indoor wall sockets, and sockets for transceiver applications. They directly equipped with standard connectors and used in communication cabinets, optical distribution boxes, protective fiber boxes, and equipment boxes. This kind of fiber optic cable is convenient and easy to install in a limited space, and becomes an ideal network optical cable solution for wiring in a limited space and inserting soft wires in buildings.

Fiber Optic Cable for Plenum Environment (Plenum Room)- An Option for Indoor Fiber Cable

In indoor applications, when the fiber optic cable needs to transmit information through a delivery duct, a high-pressure inflatable space, or an air handling system, the plenum room indoor optical cable is necessary. This special use environment places more stringent requirements on the flame retardancy and corrosion resistance of the optical cable. Therefore, the tight buffer material and outer sheath material of the indoor optical cable used are more stringent. The buffer made of PVC material. And the outer sheath material is a flame retardant PVC material that meets UL certification. The use of PVC design is better than fluoropolymers. Because PVC is soft and easy to bend, there is no trace of inventory, and it can be stored in a ring.

TOEM produces fiber optic indoor/outdoor cables, fiber optic distribution frames, fiber optic cable assemblies, etc. At the same time, it also produces optical transceiver modules, which can provide different packaging types, transmission distances and transmission rates, and also have the characteristics of stable performance and strong compatibility.
