Fiber Connector Classification

When it comes to fiber optics, people naturally understand. But what if you are referring to fiber optic connectors? What are fiber optic connectors and how are fiber optic connectors classified?

What is a fiber optic connector? How is a fiber optic connector classified?

The optical fiber connector is a component that carries out a detachable (theme activity) connection between the optical fiber and the optical fiber. It connects the two inner holes of the optical fiber with high precision, so that the optical kinetic energy output by the optical fiber at the launch point is coupled with a lower limit. It is the basic requirement of optical fiber connectors to combine into the receiving optical fiber and minimize the impact of the system due to its interference with the optical outer chain. At a necessary level, fiber optic connectors affect the reliability and various characteristics of the optical delivery system software.

How to classify fiber optic connectors

1. FC fiber optic connector

This type of connector is simple in structure, convenient in actual operation, and very easy to manufacture, but the fiber end is relatively sensitive to floating dust, and it is very easy to cause Fresnel reflection, and it is difficult to improve the return loss characteristics.

2. SC fiber optic connector

The casing is in the shape of a rectangular frame, and the structural specifications of the pin insert and coupling sleeve are the same as those of the FC type. The inner hole of the pin insert is mostly made of PC or APC type grinding method; the tightening method is to use the pin latch. type without turning. This type of connector is of high quality and low price, easy to insert and insert, small fluctuation of interference loss, high tensile strength, and high installation density.

3. ST-type fiber optic connector

ST-type optical fiber jumper: common in optical fiber distribution frame, the casing is round, and the tightening method is turnbuckle.

4. LC fiber optic connector

The size of the pin insert and sleeve specification selected is more than half of the commonly used specifications such as SC and FC, which is 1.25mm. This can improve the relative density of optical fiber connectors in the optical distribution frame.

5. Biconic Connector

It consists of 2 barrel power plugs with frusto-conical edges formed by high-precision compression molding and a coupling part with a double-cone plastic sleeve specification inside.

6. DIN4 fiber optic connector

The structure and specifications of the pin insert and coupling sleeve used for this type of connector are the same as those of the FC type, and the PC grinding method is used for the inner hole solution.

Seven, MT-RJ connector

MT-RJ started from the MT connector developed and designed by NTT. It contains the same latch structure as the RJ-45 type LAN electrical connector. According to the guide pins installed on both sides of the small and medium waterproof casing, it points to the optical fiber. The transceivers are connected, and the inner hole fiber of the connector is a dual-core (0.75mm pitch) ordering design concept, which is the next-generation compact optical connector suitable for data transmission.

Eight, MU type connector

The MU connector should be based on the SC-type connector that is the most widely used at this stage. The connector uses a 1.25mm diameter waterproof sleeve and a self-sustaining structure. Its advantages depend on maintaining a dense installation.

Fiber optic connectors are unique. Fiber optic cables send pulses of light, not electrical signals, so termination must be more precise. Rather than just allowing pins to make metal-to-metal contact, the fiber optic connector must be perfectly aligned with the microscope glass in order to allow communication. Although there are many types of fiber optic connectors, they share similar design features.
