Optical Fiber Cable Factory Introduces Cable Performance

The cable is mainly used to transmit audio, 150kHZ and below analog signals, and 2048kbit/s and below digital signals. Under certain conditions, it can also be used to transmit digital signals above 2048kbit/s. It is suitable for overhead or pipeline laying lines in urban, suburban, and local areas, and can also be directly buried. Below, Optical Fiber Cable Factory introduces the performance of the cable:

1. DC resistance: 20℃, 0.4mm copper wire, less than or equal to 148Ω/km, 0.5mm copper wire, less than or equal to 95Ω/km.

2. Dielectric strength: 1min 1kv between conductors without breakdown, conductor and shield 1min 3kv without breakdown.

3. Insulation resistance: each core is grounded with the rest of the cores, the HYA cable is greater than 10000MΩ.km, and the HYAT cable is greater than 3000MΩ.km.

4. Working Capacitance: Average 52±2nF/km.

5. Far-end crosstalk defense: The average power of the specified combination at 150kHZ is greater than 69dB/km.
