Cable TV "distributor" and "branch" difference - Database & Sql Blog Articles

The splitter divides the power of one input signal equally into several outputs, and has one input and several outputs. Generally, dispensers are generally classified by the number of output channels, so-called two-distributor, three-distributor, four-distributor, and six-distributor. There are many other classification methods for dispensers. They can be divided into indoor type and outdoor waterproof type according to different places of use. Feeding type and common type, surface mounted type and concealed type, common plastic case and metal shielding type; It can be divided into centralized parameter type and distributed parameter type. The centralized parameter type can be divided into two types: resistance type and magnetic core coupling transformer type. The distributed parameter type is microstrip line distributor.

The function of the brancher is to take a part of the signal from the transmission line and feed it to the user terminal box. It generally has a main line output and a plurality of branch outputs, and the classification manner is also divided according to the number of branch output ports. In addition, it also has a lumped parameter type and a distribution parameter type.

Since the splitter is completely different from the distributor in the distribution of energy (the output of the splitter has no primary and secondary points, the output of each branch is divided into energy; and the output of the splitter has the primary and secondary points, and the energy of the main road is divided. The branch output is absolutely dominant, so the two are completely different in terms of function, use, circuit structure and technical requirements.
