Fiber optical feeder cable is used to pull the digital baseband IQ signal far away, and the RF conversion is completed on the tower. The radio frequency remote module pulls the radio frequency part of the base station away through the optical fiber to realize the separation of the radio frequency part of the base station and the baseband part, so that the large-capacity base station can be centrally placed in the accessible central equipment room, and the baseband part is centrally processed. Using this technology, can save a large number of computer rooms required in the conventional network construction mode, save the investment of baseband unit, reduce the loss of feeders, and reduce the problem caused by the large number of feeders in the traditional radio frequency remote mode. Due to the use of digital signal transmission, the pulling distance has also been greatly improved, up to 40km.

Product introduction
The cable is also known as the base station cable, which is suitable for ordinary outdoor environments, and is often used for waterproof docking of the equipment port of the tower top and the communication base station. The skin is made of low smoke, no halogen, fire, water, and rat-proof. There are ten groups of imported tensile aramid in the core wire. Good line flexibility, little influence by wiring space, easy to retract.

Product characteristics

The use of high-strength fatigue-resistant fiber ensures the reliability and life of the cable in a variety of harsh service conditions.
The special coating layer and the composite structure of the secondary coating can absorb mechanical and environmental stress, and the additional loss of the cable is small.
The fiber SZ stranding and the single helix stranding of reinforced fiber ensure that the cable has a large tensile strain window.
High strength light weight, high strength-to-weight ratio; Circular sheath compact structure, especially suitable for repeated retracting occasions.
Flame retardant high strength, high toughness polyurethane (PU) elastomer sheath, high oxygen index, good flame retardant, oil and chemical corrosion resistance, tear resistance, low-temperature flexibility, strong elasticity, good stress cushioning, wear resistance, and pressure resistance sheath.
Tight cover color according to TIA-598-A standard color spectrum, easy to route and end the cable.
The cable jacket is printed with product information and length indication.
If the user needs it, both ends of the base station cable can be pre-installed with fast mobile connectors.

Pull-far cable advantages:
1. Reduce construction costs: reduce feeder losses and reduce the power of the power amplifier
2. Reduce operating costs: rational utilization of base station resources and centralized placement of base station baseband parts
3. To achieve rapid network construction: baseband and radio frequency are placed separately so that the project construction has a strong flexibility
4. Easy to optimize and adjust the network: according to the characteristics of the surrounding environment of the base station, the standard cellular structure is built, which reduces the difficulty of network optimization.
5. Rational use of optical network resources: the new optical cable network can also be used for data access, video surveillance, and so on.
6. Indoor coverage: effective use of network resources, reduce costs, and improve the quality of network coverage.

Application:
For outdoor wiring;
For base station wiring;
For the top of the tower wiring;
It is used for temporary wiring and may be used frequently.
