The growing demand for high speed transmission and high density cabling has led to an increase in the use of MPO|MTP patch cables. The quality of MPO|MTP fiber optic patch cables determines the stability of the entire data center network. Therefore, choosing a high quality MPO|MTP optic patch cable is crucial. Let's take a look at how to choose a high quality patch cord. Here are the key factors to consider:
Insertion loss is the power loss of an optical signal passing through a patch cord, measured in dB. High quality MPO|MTP patch cords should have an insertion loss of ≤0.5dB (multimode) or ≤0.7dB (singlemode), with lower being better. For low-insertion-loss singlemode and multimode MPO|MTP fiber optic patch cords, the insertion loss requirement is typically <0.35dB. Return loss is the loss of light reflected back from the source, reflecting the end-face's reflectivity. Singlemode 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 MPO and MTP fiber optic cables, consider choosing a supplier that provides loss test reports.
There are two main types of endfaces. 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 endface 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 UnitekFiber meet relevant standards before shipment.
The outer jacket of MPO|MTP patch cord 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 MPO|MTP 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 MPO|MTP fiber optic patch cable, you can check the flame retardancy rating directly on the outer jacket. Then, select the appropriate MPO|MTP patch cord based on the jacket and the intended application. Unitekfiber offers outer jackets in various flame retardancy grades, including PVC,OFNP, LSZH and so on, to meet your diverse needs.
Connector's material and durability are key indicators of its quality. High quality MPO|MTP fiber 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 1,000 cycles, fully meeting the stringent connector durability requirements of industrial environments.
In summary, selecting high quality MPO|MTP fiber optic patch cables requires careful attention to core components such as insertion loss, return loss, endface, polish, connectors, and outer jacket material. By focusing on these critical factors, you can confidently select an MPO|MTP patch cable that meets your system needs and will stand the test of time.
