The difference between wires and cables depends on the specifications of the wire. Generally, conductors with a cross-sectional area larger than 6 square millimeters are called large wires and cables, while those smaller than or equal to 6 square millimeters are called small wires. Insulated wires are also known as fabric wires. However, sometimes cables are also classified theoretically as wires.
AWG is another method used in the fabrication of DWDM. It is a grating formed by an array of optical waveguides arranged with specific lengths, capable of wavelength division. It is mainly used in the production of high-density wavelength multiplexers/demultiplexers (DWDM). The principle is as follows: the light source (containing modulated signals of multiple wavelengths) is first divided by a wavelength division element into several to dozens of sub-light sources with roughly equal amplitudes. These sub-light sources are then sequentially guided into an array of waveguides designed with specific lengths, each having a specific output phase. After passing through multiple output coupling elements, constructive interference occurs at specific positions for light sources of particular wavelengths, resulting in output. This allows different wavelength light sources (signals) to be distributed or extracted, achieving the purpose of wavelength multiplexing/demultiplexing.
Global Wire and Cable Industry 2018 Market Status and Trend Analysis
The wire and cable industry has become a fundamental sector in the development of China's industry. From the perspective of segmented application fields, it mainly includes power cables, electrical cables, communication cables, optical cables, submarine cables, and specialty cables. Currently, power cables and communication cables hold a higher market share. However, in terms of gross profit margin in segmented markets, submarine cables have the highest margin due to factors such as high technical barriers. With the impact of industrial structure adjustment and transformation and upgrading in China's wire and cable industry, submarine cables have become the main competitive focus for domestically strong competitive enterprises.

Anhui: 60% of wire and cable qualified
Recently, the Anhui Provincial Administration for Industry and Commerce conducted provincial-level quality monitoring on humidifiers, electric wires and cables, mobile phones, and other products sold in markets of Hefei, Chaohu, Fuyang, and Bozhou. The results showed that the pass rate for spot-checked humidifiers and mobile phones was over 70%, while 40% of electric wires and cables were found to be non-compliant.
