Do you know the difference between a fiber optic quick connector and a cold connector?

December 22, 2022

The continuous updating and advancement of optical communication technology has led to the large-scale development of FTTH (Fiber to the Home), which has promoted the expanding market size of optical fiber quick connectors. In the fiber-optic wiring process, the fiber continuation method is generally divided into two types, one is fiber-optic hot-melt. This continuation method is more complicated, and is mostly used for long-distance optical signal transmission in large-scale laying; the other is to use The quick connector is continuously connected, and its small size and easy operation make it easy to connect the fiber link even in a small space. In line with the construction deployment characteristics of FTTH, the fiber-optic fast-connected machine is widely used in FTTH network deployment. In particular, SC fiber optic connectors are widely used in field wiring and FTTH because of their high success rate and stability.

What is the role of the fiber optic quick connector?

The fiber optic quick connector is an effective tool for fast fiber termination. It consists of pre-polished pins and mechanical connectors. It does not require the use of a fiber fusion splicer or a grind during termination. The connection tool can realize the docking of the fiber link. The fiber optic quick connector can adapt to a variety of wiring environments, without other forms of protection, and the loss of optical signals is extremely low, which is an important guarantee for FTTH fiber cabling.

How to install and use the fiber optic quick connector?

Step 1: Remove the connector tail cover and pass the cable through it;

Step 2: peeling the cable sheath with a fiber stripper, the length is about 5CM;

Step 3: The Miller pliers are placed close to the edge of the jig to cut off the exposed coating layer to expose the optical fiber;

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

Step 5: cutting the optical fiber with a clamp;

Step 6: Insert the optical fiber into the main hole slot, and when the optical fiber is initially bent, press the crimp cover down;

Step 7: Screw the tail cap of the string on the cable back to the connector body and fasten the outer casing.

The installation of the fiber optic quick connector is very simple, but it should be noted that the fiber optic quick connector is highly susceptible to contamination and damage, resulting in impaired fiber performance. Keep away from dust and contaminants during installation, and the action should be slow when inserting.

What is the difference between a fiber optic quick connector and a cold connector?

The fiber cold connector has the same structural principle as the pre-embedded fiber connector. It belongs to the sub-product of the fiber optic quick connector. Because its shape is similar to the quick connector, many people are unclear about the two.

The difference between a cold connector and a fiber optic quick connector is that it has no active plug. It is used to directly fix the optical link node when the fiber is connected to the fiber or the fiber and the pigtail. The contact loss is about 0.1dB~0.2. dB. Mainly used for indoor wiring or narrow space wiring, the installation is more convenient and flexible.
