      Working principle of the coupler Shi Huabeng

      Release date:2015-06-15 15:33 Source:http://www.biricikmaket.com Views:

      Petrochemical pump coupler is from the main channel of wireless signal extract a small portion of the signal of RF devices, as shown in Figure 2, and power divider are the same as belonging to the power distribution device, different is coupler is the unequal power distribution device. Coupler and power splitter collocation is used, mainly in order to achieve a goal - so that the transmission power of the signal source can be as much as the average allocation to the indoor distribution system of each antenna port, transmit power of each antenna port is basically the same.

      Or for the extension of the fiber optic link components, belonging to the field of optical passive components, in the telecommunications network, cable television networks, subscriber loop systems, regional networks will be applied to. Optical fiber coupler can be divided into standard coupler (belonging to the waveguide type, double branch, unit 1 x 2 will light signal into two power), direct coupler (two same or different types of optical fiber interface optical connections, to extend the fiber link), stellate / tree coupler, and wavelength multiplexer (WDM, if the wavelength is the separation of high density, namely wavelength spacing narrow, belonging to the DWDM), making way for a sintering (fuse), low light level learning (micro optics), optical waveguide (wave guide) three, and to burn the resultant method production accounted for the majority (about 90%). The breakthrough of high degree of polymerization and sintering process, the two optical fibers together to melt tension, the nuclear core together, to reach the light coupling effect, and one of the most important production equipment is the optical fiber fusion splicer, is one of the important steps, although an important step in part by machine OEM, but sintering, should detect package, so labor costs account for about 10 to 15%. Moreover, the artificial detection package shall be guaranteed quality consistency, which is the production that must be overcome, but technical difficulties not if DWDM module and optical active components, so early to enter the optical fiber industry manufacturers, most from the optical coupler, the gross profit in 20 ~ 30%.

      According to the number of working cavities, the hydraulic coupler is divided into single working chamber hydrodynamic coupler, dual working chamber hydrodynamic coupler and multi working chamber hydrodynamic coupler. According to the different blade, the hydrodynamic coupler is divided into radial blade hydrodynamic coupler, inclined blade hydrodynamic coupler and rotary vane coupler. Shi Huabeng
