1. Active Connection

Active connection utilizes various fiber optic connectors (plugs and sockets) to connect site-to-site or site-to-cable.

This method is flexible, simple, convenient, and reliable, commonly used in building computer network cabling. The typical attenuation is 1dB per connection.

It allows connections to be plugged into connectors and fiber sockets. While connectors can lose 10% to 20% of light, they make system reconfiguration easy.

2. Emergency Connection (Cold Splicing)

Emergency connection, also known as cold splicing, uses mechanical and chemical methods to fix and bond two fibers together.

This method is quick and reliable, with typical attenuation ranging from 0.1 to 0.3dB per point.

However, the connection can become unstable over time, so it is only suitable for short-term use.

Mechanical methods involve placing the carefully cut fiber ends in a sleeve and clamping them. This can be done by trained personnel in about 5 minutes, with light loss around 10%.

3. Permanent Fiber Connection (Fusion Splicing)

Permanent fiber connection, also known as fusion splicing, involves melting and fusing the fiber ends together using an electric arc.

This method fits long-distance, permanent, or semi-permanent fixed connections. It has the lowest connection attenuation among all methods, with typical values ranging from 0.01 to 0.03dB per point.

Fusion splicing requires specialized equipment (fusion splicer) and professional operation.

The connection points also need to be protected in special containers. The resulting connection is nearly as strong as a single fiber, though it does introduce some attenuation.

4. Non-Splicing Physical Connection

Fibconet offers the latest physical connection solution.

Through a special V-groove design and iterative matching liquid, it achieves nearly 100% fusion success rate and permanent physical connection.

This method is suitable for FTTR solutions.

Understanding Fiber Loss

To better use fiber optics and understand fiber loss, you can use OTDR products to detect fiber connections.
