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

The continuous update and progress of optical communication technology has driven the large-scale development of FTTH (optical fiber to the home), thereby promoting the continuous expansion of the market size of optical fiber quick connectors. In the process of optical fiber wiring, there are generally two types of fiber splicing methods. One is fiber fusion. This splicing method is more complicated and is often used for large-scale long-distance optical signal transmission.

The other is the use of quick connectors for continued connection. Its small size is easy to operate. Even in a small space, it can easily realize the connection of optical fiber links. It is consistent with the construction and deployment characteristics of FTTH, so the optical fiber fast connection machine is widely used in FTTH network deployment. Especially SC fiber optic connectors are widely used in field wiring and FTTH because of their high termination success rate and strong stability.

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

How to install and use optical fiber quick connector? Step 1: Remove the connector end cover and pass the cable through; Step 2: Use fiber stripping pliers to peel the cable sheath, the length is about 5CM; Step 3: Cut the Miller pliers close to the edge of the fixture The coating layer exposes the fiber; Step 4: Wipe and clean the bare fiber with a dust cloth; Step 5: Cut the fiber with a clamp; Step 6: Align the fiber with the main hole and insert it, when the fiber is initially bent In the state, press down the crimping cap; 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 quick connector is very simple, but it should be noted that the optical fiber quick connector is extremely susceptible to contamination and damage resulting in damage to the performance of the optical fiber. It should be kept away from dust and contaminants during the installation process, and the action should be slow when inserted.

What is the difference between a fiber optic quick connector and a cold connector? 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 quick connector. Because its shape is similar to the quick connector, many people are 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 connect 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 narrow space wiring, installation is more convenient and flexible.
