The characteristics of the optical fiber ribbon cable 3.1 The number of cores is large, and the connection efficiency is high. When the ribbon fiber optic cable is connected by the ribbon fiber fusion splicer, the optical fibers of one optical fiber ribbon can be spliced ​​once, which greatly improves the connection efficiency.

 

The more cores per ribbon, the more efficient the connection; at the same time, the quality of the connection will be worse. Ordinary fiber optic cables are usually not limited by connection efficiency, and the maximum number of cores usually does not exceed 288 cores. The number of cores in fiber optic ribbon cables is mainly affected by demand. Although the current maximum is 576 cores, fiber optic ribbon cables with more than 576 cores will be widely used in the future.

 

However, when the fiber optic ribbon is connected to discrete fibers or connecting fiber optic ribbons with different core counts, the fiber ribbon needs to be torn into individual fibers for connection, which is more troublesome than connecting. Ordinary fiber optic cable.

Connection loss is high. Since fiber ribbons are connected, there is no guarantee that all fibers within the ribbon can be precisely aligned, so the connection attenuation is greater than that of a single core. Losses related to single core and fiber optic ribbon connections.

 

The outer diameter of the small core cable is larger. When the number of cores of the optical cable is less than 144, the outer diameter of the optical fiber cable is obviously larger than that of the ordinary optical cable. When the core is 144 or larger, the outer diameter of the fiber optic ribbon cable is similar to that of the ordinary fiber optic cable.

 

The investment difference between the project investment optical fiber ribbon cable and ordinary optical cable is mainly reflected in two points:

(1) The price difference of optical cable;

(2) Differences in connection prices. From the production cost point of view, the production process of fiber optic ribbon cable is much more, and the cost will be higher. However, the price of an item often depends on the quantity purchased and the competitive environment.

 

At present, with the increase in the use of fiber optic ribbons, the unit price and unit price of ordinary fiber optic cables are getting closer and closer. For example, you can see the price of certain fiber optic cables from a certain operator. Due to the high connection efficiency of fiber optic ribbon cables, the connection cost per connector is relatively low; the larger the core count of the fiber optic ribbon, the more obvious this advantage is. Fiber optic cable connectors for different types of fiber optic cables in the budget. Overall, the cost of using fiber optic ribbon cable in the project is slightly lower than that of ordinary fiber optic cable.

 

Advantages and Disadvantages Summary The advantages and disadvantages of fiber optic ribbon cables are as follows:

Advantages: high connection efficiency and low cost;

Disadvantages: It needs to be equipped with a fusion splicer, which has the ability of optical fiber ribbon fusion, and the connection loss is large, continuous or different from ordinary optical cables. The number of fiber cores is less efficient when connecting.

 

It is recommended to use optical cables in large and medium-sized metropolitan area networks. The number of optical cable cores (not less than 72 cores) is large, such as the core layer of the metropolitan area optical cable and the backbone section of the access layer. Trunk fiber optic cables, other fiber optic cable segments with a relay distance of more than 70km, the lead-in part of the access layer fiber optic cable (distribution optical crossover distribution box segment) and other segments with a small number of fiber optic cable cores are not suitable for fiber optic cables.

 

Others suggest that the number of cores of the optical fiber ribbon in the optical cable should be uniform, preferably 12 cores and 6 cores. Various core numbers are not recommended. Otherwise, the number of cores of the fiber optic ribbon may not match when connecting the fiber optic cable.
