The difference between optical fiber quick connector and cold connector

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 quick connectors. 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 to operate and is mostly used in long-distance optical signal transmission for large-scale laying; the other is to use The quick connector is used for connection, its small size is easy to operate, and the optical fiber link can be easily connected even in a small space.

Consistent with the construction and deployment characteristics of FTTH, optical fiber fast connection machines are 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 does a fiber optic quick connector do?

The optical fiber quick connector is an effective tool to realize the quick termination of optical fiber. Its interior is composed of pre-polished pins and mechanical connectors. It does not require a fiber fusion splicer or grinding during termination. The connection tool can realize the docking of the optical fiber link. The optical fiber quick connector can adapt to various wiring environments without other forms of protection, and the loss to the optical signal is extremely low, which is an important guarantee for the realization of FTTH optical fiber wiring.

How to install and use optical fiber quick connectors?

Step 1: Remove the connector end cap and pass the cable through it;

Step 2: Use optical fiber strippers to strip the cable sheath, the length is about 5CM;

Step 3: Cut the exposed coating layer with the Miller clamp close to the edge of the clamp to expose the fiber;

Step 4: Wipe and clean the bare fiber with a dust-proof cloth;

Step 5: Cleave the fiber with a fixture;

Step 6: Align the optical fiber with the main body slot and insert it. When the optical fiber is initially bent, press the crimping cover down;

Step 7: Screw the end cap on the cable back to the main body of the connector and then fasten the shell.

The installation of the optical fiber quick connector is very simple, but it should be noted that the optical fiber quick connector is extremely susceptible to contamination and damage, which will lead to the loss of optical fiber performance. During the installation process, it should be kept away from dust and contaminants, and the action should be slow when inserting.

What is the difference between fiber optic quick connectors and cold splices?

The optical fiber cold splicer has the same structure principle as the pre-buried optical fiber connector. It is a sub-product of the optical fiber quick connector. Because its shape is similar to the quick connector, many people are stupid and unclear about the two.

The difference between the cold connector and the optical fiber quick connector 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 joint loss is about 0.1dB~0.2 dB. It is mainly used for indoor wiring or wiring in a small space, and the installation is more convenient and flexible.
