The values in front of the AWG (such as 24AWG, 26AWG) indicate the number of holes to be passed before the final diameter of the wire is formed・ The larger the number, the more holes the wire passes through, and the smaller the diameter of the wire. Thick wires have better physical strength and lower resistanee, but the thicker the wire, the more copper it needs to make the cable, which causes cables to become heavier, harder to install, and more expensive・ The challenge of cable design is to use the wires with the smallest possible diameter (cost reduction and installation complexity), while ensuring the maximum capacity of the wire under the necessary voltage and frequency.The diameter, area and weight of the wires with different AWG valuesAWG diameter (inch) diameter (mm) area (MIL) area (mni2) weight(kg / km)220. 0253 0. 643640. 4 0. 3256 2. 895230. 0226 0. 574511.5 0. 2581 2. 295240. 0201 0. 511404 0. 2047 1. 820260.0159 0. 404253 0. 1288 1. 145The size of the upper table was determined more than 100 years ago, and with the development of technology, the performance of the wire continues to improve・ Fot conductors, the more important is their performance, especially the impedance of ohms as a unit・ So the century size of the wire can be slightly larger or smaller than the actual specification (usually a little smaller)・2. AWG arrayed waveguide gratingAWG is another way to make DWDM. The grating formed by a set of optical waveguides of specific length, using the ability to separate waves・ It is mainly used in the fabrication of high density wavelength multiplexer / demultiplexer (DWDM)・ The principle is: first light source (including multiple wavelength light modulated signal) by wave element is divided into several sub light source amplitude is approximately equal, then the array waveguide sub light source in order to import the designed length, which has its own specific output phase, through multiple output the coupling element, for a specific wavelength light source will form constructive interference in a specific location and output・ In this way, the light source (signal) of different wavelengths can be allocated or captured to achieve wavelength multiplexing and multiplexing・AWG was the first to apply planar waveguide Circuit (Planar Lightwave) technology to commercial components・ The practice for depositing a two oxide on silicon wafer of silicon (Si02) film by photolithography (Photolithography) and reactive ion etching (Reactive Ion Etch) defines the array waveguide and optical elements, then in the top covered with a protective layer can be completed・ Due to the use of AWG process with the same general semiconductor, not much difference in the cost of making multi channel number and low number of channels, but it is more suitable for mass production, and integration (integration) is high, so it has a good potential in multi channel components and the later development・AWG (American Wire Gauge) refers to the American wire ga.uge，/AWG specificationAWG specification AWG AWGLine number inch inch mm mm (mm)10. 2893 7. 35 0. 300 7. 6220. 2576 6. 54 0.276 7.0130. 2294 5.83 0. 252 6. 400. 20435. 190. 2325. 890. 18194. 620.2125. 380. 16204. 110. 1924. 880. 1443 3. 670. 1764. 470. 1285 3. 260. 1604. 060. 1144 2.910. 144 3. 6610 0.10192. 590. 1283. 2511 0. 09072. 300. 1162. 9512 0.08082. 050. 1042. 6413 0.07201.830. 0922. 3414 0. 06411.630. 0802. 0315 0. 05711.450.0721.8316 0. 05081.290. 0641.6317 0. 04531. 150. 0561.4218 0. 0403 1.02 0. 048 1.220. 0359 0.912 0. 040 1.020. 0320 0.813 0. 036 0.9140. 0285 0. 724 0. 032 0.8130. 0253 0. 643 0. 028 0. 7110. 0226 0.574 0. 024 0.6100. 0201 0.511 0. 022 0. 5590.0179 0. 455 0. 020 0. 5080.0159 0. 404 0.0180 0. 4570.0142 0. 361 0.0164 0.4170.0126 0. 320 0.0148 0.3760.0113 0. 287 0.0136 0. 3450.0100 0. 254 0.0124 0.3150. 0089 0. 226 0.0118 0. 2950. 0080 0. 203 0.0108 0. 27490. 0071 0. 180 0.0100 0. 2540. 160 0. 0092 0. 2340. 142 0. 0084 0.2130. 127 0. 00760. 114 0. 00680. 1020. 0890.0790.0710. 0044 0. 1120. 064 0. 00400. 056 0. 00360. 051 0. 00320. 046 0. 00280. 00630. 00560. 00500. 00450. 00400. 00350. 00310. 00280. 00250. 0022。
