MPO (Multi-fiber Push-On) optical fiber jumpers are commonly used in data centers and telecommunications networks due to their high-density, high-bandwidth capabilities. However, the use of MPO jumpers requires careful attention to detail to ensure proper performance and reliability. In this article, we will discuss some of the precautions that should be taken when using MPO optical fiber jumpers.
Connector Types
MPO connectors are available in two types: MPO Male and MPO Female. MPO Male connectors have pins that mate with the holes in the MPO Female connector, while MPO Female connectors have holes that mate with the pins in the MPO Male connector. It is essential to ensure that the correct type of MPO connector is used when connecting MPO jumpers.
Connector Polarity
MPO connectors have three polarity options: Type A, Type B, and Type C. Each type of polarity specifies the arrangement of the fibers within the connector, and it is essential to ensure that the correct polarity is used when connecting MPO jumpers. Mismatched polarity can result in signal loss or signal distortion.
Cable Preparation
Proper cable preparation is critical for ensuring that the optical fibers are not damaged during installation. The cable should be stripped and cleaned using a specialized fiber optic cleaning kit to remove any contaminants. The stripped fibers should be inspected for any nicks or scratches that can cause signal loss. The fibers should also be properly cleaved to ensure a clean and flat end face.
Connector Termination
Connector termination is the process of attaching a connector to the stripped fiber end. MPO connectors are typically field-terminated using a specialized tool. Proper termination is critical for minimizing insertion loss and ensuring signal integrity.
Connector Inspection
After connector termination, the connector should be carefully inspected for any defects. The connector end face should be examined for any scratches, chips, or other damage that can cause signal loss. The connector should also be checked for cleanliness and flatness. Any defects should be addressed promptly before the connection is completed.
Cable Management
Proper cable management is crucial for ensuring that MPO jumpers are not subjected to excessive bending, pulling, or twisting, which can cause signal loss or damage to the fibers. Cable management should include proper routing, strain relief, and protection from environmental factors such as temperature and humidity.
Testing
Once the optical fiber channel connection is complete, it is important to perform testing to ensure that the connection is functioning correctly. Testing should include measuring insertion loss, return loss, and attenuation. Any issues should be addressed promptly to prevent downtime or data corruption.
Conclusion
MPO optical fiber jumpers require careful attention to detail to ensure proper performance and reliability. Connector types, connector polarity, cable preparation, connector termination, connector inspection, cable management, and testing are all critical aspects of a successful MPO optical fiber jumper installation. Following these precautions can prevent signal loss, data corruption, and network downtime, and ensure that MPO optical fiber jumpers provide reliable and efficient performance.
