How to Check the Quality of Fiber Optic Adapter?

Publish Time:2021,11,03

The fiber optic adapter is the centering connection part of the optical fiber movable connector. The optical fiber adapter can precisely connect the two end faces of the optical fiber, so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the same or different optical fiber movable connectors can be connected to make it under little loss. The light path is unblocked.

With the wide application of fiber optic adapters in fiber optic connections, there are various fiber optic adapters with different interfaces to choose from to meet the installation requirements of different environments. Common types of fiber optic adapters are: LC adapter, FC adapter, SC adapter, ST adapter, E2000 adapter, MTP / MPO adapter, etc.

Faced with so many types of fiber optic adapters, how to choose a suitable and high-quality adapter is particularly important. Generally speaking, when considering fiber optic adapters, the following points should be considered.

Ⅰ. Key performances that affect the fiber optic adapter

1. The flame retardant level of the fiber optic adapter

The flammability UL94 rating is the most widely used plastic material flammability performance standard. It is used to evaluate the ability of a material to extinguish after being ignited. According to the burning speed, burning time, anti-drip ability and whether the drops are burning, there are many ways to judge. HB, V0, V1, V2 are different flame retardant grades, their grades are different, the test methods for flame resistance are also different, and the standards for test judgment are also different. The flame retardant grades are gradually changed from HB, V-2, V-1 to V-0. The level increases.

2. Insertion loss of fiber optic adapter

The insertion loss is generally required to be less than 0.2dB. If the insertion loss is too high, it will affect the optical transmission.

3. Repeatability of fiber optic adapter

Fiber optic adapters need to be plugged and unplugged frequently during use. Therefore, the durability of fiber optic adapters is high. Normal standards need to ensure that the insertion loss does not change, and the number of plugging and unplugging can reach more than 500 times without affecting performance.

4. Working temperature of fiber optic adapter

-40℃~75℃ is a normal working range of fiber optic adapter.

5. The material of the fiber optic adapter aligned with the sleeve

The alignment sleeve is the most important part of the optical fiber adapter. Generally, metal or ceramic materials are used. The use effect of ceramic fiber adapters will be relatively good. Because the crystal structure of ceramics is hard and not easy to deform, it can achieve rapid alignment and high height. Precision optical fiber end-to-face connection.

When choosing a fiber optic adapter, you can filter out relatively high-quality and stable fiber optic adapters through the above several important properties. Of course, you need to consider other factors that affect quality, such as tensile strength and compliance standards.

Ⅱ. The wide applications of fiber optic adapter

Used in communication room, FTTH fiber to the home, local area network, fiber optic communication system, fiber optic connection transmission equipment, national defense combat readiness, etc. Although the fiber optic adapter product is small, its quality directly affects the entire optical fiber link. The quality of the product should be rigorous and comprehensive.
