The continuous update and progress of optical communication technology has driven the large-scale development of FTTH (Fiber to the Home), thereby promoting the continuous expansion of the market scale of Optical Fiber Joint Boxs. In the process of optical fiber wiring, there are generally two ways to connect optical fibers. One is optical fiber thermal fusion, which is more complicated in operation, and is mostly used for large-scale long-distance optical signal transmission; the other is to use The quick connector is used for continuous connection, and its small size is easy to operate, and the optical fiber link can be easily connected even in a small space. It is consistent with the construction and deployment characteristics of FTTH, so the fiber optic fast connection machine is widely used in FTTH network deployment. Especially the SC fiber optic connector is widely used in field wiring and FTTH because of its high termination success rate and strong stability.
What is the function of the Optical Fiber Joint Box?
The Optical Fiber Joint Box is an effective tool for fast optical fiber termination. Its interior is composed of pre-polished pins and mechanical connectors. It does not need to use an optical fiber fusion splicer, nor does it need to be polished, through a simple The connection tool can realize the docking of the optical fiber link. The Optical Fiber Joint Box can adapt to a variety of wiring environments without other forms of protection, and has extremely low loss of optical signals. It is an important guarantee for the realization of FTTH optical fiber wiring.

How to install and use the Optical Fiber Joint Box?
Step 1: Remove the connector tail cap and pass the cable through it;
Step 2: Use an optical fiber stripper to peel off the cable sheath, the length is about 5CM;
Step 3: Put the Miller clamp close to the edge of the fixture and cut off the exposed coating to expose the optical fiber;
Step 4: Wipe and clean the bare fiber with a dust-proof cloth;
Step 5: Use a clamp to cut the fiber;
Step 6: Align the optical fiber with the main body hole and insert it. When the optical fiber is initially bent, press down the crimping cover;
Step 7: Screw the tail cap stringed on the cable back to the connector body and buckle the shell.

The installation of the Optical Fiber Joint Box is very simple, but it should be noted that the Optical Fiber Joint Box is easily contaminated and damaged, resulting in damage to the performance of the optical fiber. The installation process should be kept away from dust and pollutants, and the action should be slow when inserting.
What is the difference between Optical Fiber Joint Box and cold splice?
The optical fiber cold splice has the same structural principle as the embedded optical fiber connector. It is a sub-product of the Optical Fiber Joint Box. Because its shape is similar to the quick connector, many people are stupid and unclear about the two.
The difference between the cold splice and the Optical Fiber Joint Box is that it has no movable plug. It is used to directly fix the optical link node when the optical fiber is connected to the optical fiber or the optical fiber and the pigtail. The contact loss is about 0.1dB~0.2 dB. Mainly used for indoor wiring or wiring in narrow spaces, making installation more convenient and flexible.
