ABB NTAC-02 fiber optic cable

Core positioning and technical characteristics

The core positioning of NTAC-02 fiber optic cable is "industrial grade high reliability optical signal transmission medium", and its design revolves around the three core requirements of "low loss, strong anti-interference, and high adaptability". Compared with ordinary commercial fiber optic cables, it has the following outstanding technical characteristics:

1. Low loss and high fidelity transmission: High purity quartz fiber core (core diameter 9 μ m, cladding diameter 125 μ m) is used, combined with high-quality coating materials. The attenuation rates in commonly used industrial optical transmission windows such as 850nm and 1310nm are as low as 0.3dB/km and 0.1dB/km, respectively, ensuring that optical signals maintain high fidelity even after long-distance transmission (up to 2km support), without communication errors caused by signal distortion or attenuation.

2. Extremely strong electromagnetic anti-interference ability: Based on the physical characteristics of fiber optic transmission, it is completely unaffected by strong electromagnetic interference (EMI), radio frequency interference (RFI), and common mode voltage in industrial sites. Compared with copper cable transmission, it can effectively avoid the interference of electromagnetic radiation generated by frequency converters, high-power motors, high-voltage equipment, etc. on communication signals, ensuring communication stability in harsh electromagnetic environments.

3. Industrial grade structural protection: Adopting a four layer protection structure of "fiber core buffer layer armor layer outer sheath", the buffer layer is made of low elastic modulus material to absorb vibration and impact, the armor layer is made of galvanized steel wire braided structure (tensile strength ≥ 1500N), and the outer sheath is made of PVC material that is resistant to oil, acid and alkali (in accordance with UL94 V-0 flame retardant standard), which can withstand mechanical wear, chemical corrosion and flame invasion in industrial sites.

4. High adaptability connection design: ABB specific SC/LC fiber optic connectors (subdivided according to model) are standard, and the connectors use ceramic plug cores (plug-in times ≥ 1000 times), with insertion loss ≤ 0.2dB and return loss ≥ 50dB. They can directly adapt to various ABB optical communication modules (such as XVC768AE102 optical expansion interface) and industrial switches, without the need for additional adapters, reducing the risk of connection failures.

5. Wide temperature adaptability: The working temperature range covers -40 ℃~+85 ℃, and the storage temperature range is -60 ℃~+100 ℃. It can maintain structural stability and transmission performance in extreme industrial environments such as high and low temperatures, without performance degradation caused by embrittlement or softening, and is suitable for various harsh working conditions.

Core functions and application value

As the "physical transmission link core" of industrial communication systems, NTAC-02 fiber optic cable focuses on low loss transmission of optical signals, environmental protection, and system adaptation. The specific core functions and application values are as follows:

1. Long distance high bandwidth signal transmission

With low attenuation fiber core design and high bandwidth characteristics (bandwidth ≥ 1000MHz · km), it can support stable transmission of 100Mbps industrial Ethernet signals for 2km, and the transmission distance of 10Mbps signals can reach 10km. Compared with traditional copper cables (such as CAT6 network cables with a transmission distance of only 100m), it greatly improves the transmission coverage range. In large thermal power plants, long-distance communication between the boiler control system and the central control room can be achieved without the need for additional signal relay equipment, reducing system complexity and costs.

2. Communication protection in extreme environments

The four layer protective structure and special material selection enable it to have comprehensive environmental adaptability: the oil and acid alkali resistance of the outer sheath can adapt to the oil and corrosive gas environment in the petrochemical workshop; The high-strength design of the armor layer can resist mechanical collisions and vibrations in metallurgical workshops; The wide temperature characteristic can meet the communication needs of outdoor control cabinets and indoor systems in cold northern regions, ensuring uninterrupted communication links under various extreme working conditions.

3. Electromagnetic interference isolation transmission

In strong electromagnetic environments such as conventional nuclear power islands and electrolytic aluminum workshops, ordinary copper cables are susceptible to electromagnetic interference that can cause communication interruptions or data errors. However, NTAC-02 fiber optic cables completely isolate electromagnetic effects through optical signal transmission, ensuring accurate transmission of high-precision data collected by modules such as XVC768AE102 to the controller, avoiding control accuracy degradation or system misoperation caused by communication interference.

4. System security and redundancy assurance

Supporting the use of redundant communication architecture in conjunction with ABB control systems, it can serve as the core transmission medium for redundant communication links. When the main link fails, the redundant fiber optic link can switch within milliseconds to ensure uninterrupted data transmission. In large-scale hydrogenation units in the petrochemical industry, this function can avoid production shutdowns caused by communication interruptions and enhance system safety redundancy.

5. Convenient installation and long-term stability

Fiber optic cables have good flexibility (bending radius ≥ 20mm), making them easy to wire inside control cabinets and cable trays; The standard dedicated connector adopts a snap on design, which is easy to plug and unplug and firmly connected, effectively avoiding looseness caused by vibration; The high wear resistance of ceramic inserts ensures low insertion loss even after long-term use, reducing maintenance costs and fault risks.
