Fiber optic terminal box used in FTTH, FTTB and FTTC

OMC takes you to understand fiber optic terminal box

Fiber optic terminal box is used in FTTH and FTTB to protect the connection points where optical cables access the user end, making the optical cable access points stable, dustproof and waterproof, and minimizing the interference of the external environment on optical cable access signals.

Application scenarios of fiber optic terminal box

Fiber optic terminal box is generally used in three scenarios, FTTH, FTTB and FTTC. This is the last mile project of optical fiber communication. The installation methods of fiber optic terminal box is also different in the three scenarios.

FTTH is installed on the floor, FTTB is installed on the wall of building, and FTTC is generally installed on electric poles in rural areas.

Classification of fiber optic terminal box

Fiber optic terminal box can be divided into 4 cores, 6 cores, 8 cores, 12 cores, 16 cores, 24 cores, 36 cores, 48 cores, etc. according to their capacity.

According to the installation method, it can be divided into wall-mounted and pole-mounted.

According to application scenarios, it can be divided into indoor type and outdoor type.

The material of fiber optic terminal box

At present, the mainstream materials of fiber optic terminal box include: SMC, ABS+PC, ABS, and PP. The quality of these four materials ranges from good to poor, and the cost ranges from high to low. The quality difference between different materials is considered in terms of material density, gloss, heat resistance, impact resistance, pressure resistance, wear resistance, flame retardancy, etc. The most cost-effective among the four materials is ABS+PC, which can meet most material requirements and has a moderate cost.

Development Trend of fiber optic terminal box

The product development trends of fiber optic terminal box is developing in two directions based on the current market and supply situation.

The first direction is to make construction faster and simpler, saving customers construction costs.

The fiber optic terminal box closes the box after assembling the PLC splitter. Users do not need to open the fiber optic terminal box and connect the network signal directly through the quick connection on the outside of the fiber optic terminal box. After the installation is completed, they only need to unscrew the connector below to connect to the quick connector on the user side. On the one hand, it reduces labor costs. On the other hand, there is no need to open the fiber optic terminal box again, which also provides better dust protection. ​

The second direction is that functions tend to be diversified. Especially in rural areas with low population density, some of the optical fibers of an optical cable are often idle. Optical cables not only need to be split, but also connected. Therefore, the new fiber optic terminal box will have a connection function to allow unused optical cables to be transferred to other places again through connections.

The general direction of network communication technology is faster transmission speed, wider transmission bandwidth and more accurate data transmission. All optical fiber communication products must take this as the development direction. The fiber optic terminal box is just a protection device, and its main function is to protect the safety and stability of the optical distribution nodes. Its development trend is to continuously reduce costs while ensuring protective performance, making construction faster and saving labor costs.
