Ningbo Dongda Communication Technology Co., Ltd. FTTH optical cable box
Ningbo Dongda communication is located in Cixi City, Henghe Industrial Park, the brand: blue channel technology; factory specializing in the production of various separation box, optical splitter box, from the core range of 6 to 72; the separation box of FTTH used in the optical scheme of branch cable, when the user policy into the end of melting straight, like an installation in the corridor and electric poles.
If a two stage scheme requires the use of a light splitter, a multi beam fiber splitter can be slotted in the box, and a 2-4 beam splitter is installed for the distribution cable and the home indoor cable connection point, which is suitable for the optical access network. Box wall or pole installation, suitable for indoor and outdoor two scenes used; through the SC brand light fast connector connected to outdoor armored cable and home indoor cable connection and scheduling.
The utility model can be arranged on the outdoor wall and the position of the electric pole to complete the connection, and the distribution function of the cable is convenient, and the arrangement of the light splitter and the light function can be satisfied.
1. Outer wall wall, pole type selection.
2. Box material adopts high quality SMC material, the appearance of spraying, gloss is good. Over 20 years of service life.
Three. It integrates welding, lighting and distribution. It can realize cable connection and direct investment.
4. The utility model has the advantages of convenient operation and reasonable structure.
5. Fixed cable, grounding convenient, enough terminal box space.
6, the use of turning plate structure, high-density configuration of ports and lighting facilities.
7. The double-layer structure is designed, and the upper layer is an optical branching device wiring layer, and the lower layer is an optical fiber welding layer;
8. The light splitting module is designed with a drawer type module, which has strong interchangeability and versatility;
