  • Classification of Optical Fiber Communication Signal Wavelengths

    Classification of Optical Fiber Communication Signal Wavelengths

    Optical communication is mostly conducted in the wavelength region from 1260 to 1625 nm. The region comprises five bands called the O-, E-, S-, C- and L-bandsThis article introduces the concept of optical wavelength bands, explains how they are classified, explores how WDM (Wavelength Division Multiplexing) uses them to increase capacity, and highlights common use cases. The values presented below are approximate and should be considered as such, as standardized values are still evolving. This standardization ensures interoperability between different manufacturers' equipment and facilitates the global deployment of fiber optic networks.

  • Cable and Optical Cable Combustion Performance Classification

    Cable and Optical Cable Combustion Performance Classification

    Since July 2017, all power, control and communication cables permanently installed in buildings must comply with the Construction Products Regulation (CPR). This includes classification under BS EN 13501-6, which assesses cables for their reaction to fire. In recent years, due to the extensive application and inherent fire hazard of cable materials, the combustion characteristics of frequently used cables, including electrical cables, wires, optical fibers, and network cables have been studied based on ISO 5660 cone calorimetry. The following performance must also be met, including Heat Release Rate, HHR below 30, Total Heat Releas s for the higest result. Kordz Group Limited is a limited liabilities company registered in Hong Kong under Company Register Number 68045642 and with its registered office at Unit A10, 8/Floor, Block A, Mai Hing Industrial Building, 16-18 Hing Yip Street, Kwun Tong, Kowloon, HONG KONG.
