THE WORLD'S FIRST S+C+L 3-BAND ULTRA-LOW-INTENSITY MULTI-CHIP CABLE HAS BEEN OPENED IN QINGDAO

News from IT House, 2 June, according to Daily Science and Technology today, recently the first S+C+L three-band (short band + conventional communication band + long band) of the world, designed by China's Mobile Union Industrial Partnership, was extremely low and damaged. The fibre-optic cable is officially operational on Qingdao in Shandong.

IT House Note: The three-band S-band (short-band) + C-band (conventional communication band) + L-band (long-band) is the core upgrading direction of AI, full-light network, 5G-A / 6G.

This new fibre-optic cable was described as breaking the traditional fibre-optic transmission capacity limit, marking a new phase in commercialization of our technology for the integration of space-based and multi-band fibre-optics. The measured data show that the fibre-optic cable is fully superior to the commercial level of the current network, with only 0.189 dB per kilometre of transmission loss; that the inter-chip disturbance is below -40dB/100km, with almost no interference in the route; and that all the indicators of dispersion, macro wear and tear meet commercial standards.

The fibre optic innovation uses a four-chip fibre-optic structure, integrates four-way independent signal channels within a thin, silk-like fibre, and expands ultra-low wear and tear, large active area properties from the C and L bands to the S-bands, achieves a "three-band parallel transmission" with a single-chip bandwidth increase of nearly 50 per cent and a single fibre-optic capacity of more than five times the traditional fibre-optic capacity, which meets the AID, T-bit-class hypervelocity transmission needs.

Based on this line, China ' s mobile completed the S+C+L full-spectral real-time transmission test, achieving a clean code, low-diversity stable transmission, and marking technology completed a critical crossing from the laboratory to the current network pilot.
