How to Choose High Quality MTP MPO Fiber Optic Patch Cords?

The growing demand for high-speed transmission and high-density cabling has led to an increase in the use of MTP MPO fiber optic patch cords. The quality of MTP MPO fiber optic patch cords determine the stability of the entire data center network. Therefore, choosing a high quality MTP MPO fiber optic patch cords is crucial. Let’s take a look at how to choose a high-quality patch cord.

And here are some the key factors to consider:

1- Insertion Loss and Return Loss

- Insertion loss (IL) is the power loss of an optical signal passing through a patch cord, measured in dB. High quality MTP MPO fiber optic patch cords should have an insertion loss of ≤0.5dB (multimode) or ≤0.7dB (single mode) for standard Insertion loss grade, with lower being better. For Ultra low insertion loss (Ultra Low Loss) single mode and multimode MTP MPO fiber optic patch cords, the insertion loss requirement is typically <0.35dB.

- Return loss (RL) is the loss of light reflected back from the source, reflecting the end-face’s reflectivity. Single mode fiber optic patch cords are typically required to have a return loss of ≥50dB (APC end-face) or ≥30dB (UPC end-face), with higher being better.

Only products that pass 100% of the required insertion loss and return loss tests with an insertion loss and return loss tester are released. When selecting MTP MPO fiber optic patch cords, consider choosing a supplier that provides loss test reports.

2- End-face Quality and Polishing Process

There are two main types of end-faces: UPC and APC.

- UPC (blue) uses a curved polish, resulting in lower return loss.

- APC (green) is polished at an 8° angle, resulting in higher return loss and suitable for high-speed networks.

During inspection, ensure the end-face is free of scratches, dents, and contamination. In order to ensure that the fiber optic connector has qualified or higher performance, the International Electrotechnical Commission (IEC) has developed the IEC 61300-3-35 standard to define whether the connector end face is qualified. All connectors manufactured by KCO Fiber meet relevant standards before shipment.

3- Cable Outer Jacket

The cable outer jacket of MTP MPO fiber optic patch cords can be made from a variety of materials with varying fire resistance, including PVC and LSZH. Most of these materials offer excellent flame retardancy. For installations requiring more stringent requirements, such as suspended ceilings and raised floors, it’s best to choose an MTP MPO fiber optic patch cord with a higher flame retardancy rating, as it’s less likely to burn or emit smoke in the event of a fire. When purchasing an MTP MPO fiber optic patch cord, you can check the flame retardancy rating directly on the outer jacket. Then, select the appropriate MTP MPO fiber optic patch cords based on the jacket and the intended application. KCO Fiber offers outer jackets in various flame retardancy grades, including PVC, LSZH and so on, to meet your diverse needs.

4- MTP MPO Fiber Optic Connectors

Connector’s material and durability are key indicators of its quality. High quality MPO|MTP fiber optic connectors are often constructed from metal or high strength engineering plastics. These materials offer excellent plug in/plug out resistance, maintaining structural stability during frequent plugging and unplugging operations. They are also resistant to deformation due to external forces, ensuring a good connection over time. Industrial grade patch cords excel in plug in/plug out cycles, typically enduring at least 500 plug-in/plug-out cycles, with some high-quality products exceeding 1000 cycles, fully meeting the stringent connector durability requirements of industrial environments.

Conclusion

In summary, selecting high quality MTP MPO fiber optic patch cords require careful attention to core components such as insertion loss, return loss, end-face, polish type, connectors type, and cable outer jacket material.

By focusing on these critical factors, you can confidently select an MTP MPO fiber optic patch cord that meets your system needs and will stand the test of time.
