Drop cables are commonly known as indoor suspended wiring optical cables. In optical fiber access projects, indoor wiring close to users is a complex link. The bending performance and tensile performance of conventional indoor optical cables can no longer meet the requirements of FTTH (fiber to the home) indoor wiring. need. However, as a new type of product, drop cable is not only reasonably priced, but the quality is also very good compared to other products.
The new DROP OPTICAL CABLE has a small outer diameter, is light in weight, and is easy for users to construct, thus solving the problem of casing retraction. The remaining fiber length is controlled stably. After the cable is passed, the additional attenuation of the optical fiber is close to zero, the dispersion value does not change, and the environmental performance is excellent. The applicable temperature range can reach about -40℃~+70℃.
Secondly, the small size of the optical cable is conducive to the final engineering of the wiring. The new sheathed optical cable has a flat structure, mainly composed of two 250MM optical fibers and two parallel high-strength parts. It is easy to peel off, can be installed, and is simple and convenient to operate. .
The drop cable is also called indoor suspended wiring optical cable. The scientific name of the optical cable is: butterfly entrance optical cable for access network. Because of its butterfly shape, it is also called butterfly optical cable or figure-8 optical cable. However, optical cables are mostly 1 core drop cable, 2 core drop cable, 4 core drop cable, The dual-core structure can also be made into a 12 core drop cable. The cross-section is in the shape of an 8. The reinforcement is located at the center of the two circles. It can be a metal or non-metal structure. The optical fiber is located in the 8-shaped shape. the geometric center. In projects such as FTTX, it can be used on a large scale, and its communication quality is very good, which is mainly due to the protection of reinforced parts.
There are generally two types of reinforcements for drop cables: metal reinforcements and non-metal reinforcements. Metal reinforcements are suitable for outdoor use and can bear the weight of drop cables. However, if the quality of the metal reinforcements is too low, it will cause damage to the drop cables and cause waste; non-metallic reinforcements are suitable for indoor use to protect optical fibers. , if the quality of the non-metal reinforcement is not good, the optical cable will suffer losses, and in severe cases, the drop cable needs to be replaced.
In short, no matter which type of reinforcement is used for the drop cable, it can play a role in the installation and application of the drop cable. If you have any technical questions or project quotation inquiries, please feel free to contact our online technical/salesman.
