MPO fiber optic connector is a multi-core fiber optic connector with certain polarities. Correct polarity is important to ensure proper signal transmission and minimize insertion loss.
The following are ways to identify the polarity of MPO fiber optic connectors:
1. Observe the appearance of the connector: MPO connectors usually have a small raised part and a small recessed part on the end face. This is used to help align the polarity of the connector correctly.
2. Observe the connector identification: MPO connectors are usually marked with a number from 1 to 12, indicating the number of each fiber. If the numbers are orthogonal, then the polarity of the connector is correct. If the numbers are inverted, then the polarity of the connector is reversed.
3. Observe the key position of the connector: The key position of the MPO connector is usually located on the left or right side of the connector. If the key is on the left side, the polarity of the connector is positive. If the key is on the right side, the polarity of the connector is reversed.
4. Use a connector tester: Some MPO connector testers can detect the polarity of the connector. This method allows you to quickly and accurately determine the polarity of the connector.
Before installing MPO fiber optic connectors, be sure to correctly determine the polarity of the connector to ensure the stability and reliability of signal transmission.
