How to Choose a Correct MPO MTP Patch Cord?

MPO (Multi-Fiber Push-On) and MTP (Multi-fiber Termination Push-on) patch cords are essential components in high-density fiber optic networks. They are widely used in data centers, telecommunications, and other high-speed communication infrastructures. Selecting the correct MPO/MTP patch cord is crucial to ensuring optimal performance and reliability in your network. This guide will help you choose the right MPO/MTP patch cord based on your specific requirements.

1. Understand the Difference Between MPO and MTP

Before you start selecting an MPO/MTP patch cord, it’s important to understand the difference between the two terms. While both refer to the same type of connector and cable system, there are subtle differences:

• MPO: MPO is the generic term for multi-fiber push-on connectors. MPO connectors can have various configurations, typically offering 12 or 24 fibers in a single connector.

• MTP: MTP is a specific brand of MPO connectors, manufactured by US Conec. MTP connectors offer enhanced features like better performance and improved durability compared to generic MPO connectors. They are often preferred for high-performance, high-density networks.

While both MPO and MTP connectors are used interchangeably, if you're looking for higher-quality and more durable connectors, MTP is often the better choice.

2. Determine the Fiber Count

The fiber count is one of the first factors to consider when choosing an MPO/MTP patch cord. These patch cords typically come with configurations like 8, 12, 24, 48, and even 72 fibers in a single cable. The choice of fiber count will depend on the number of fibers you need to transmit data within your network.

For instance, if your network requires 12 fibers for connection, you should select a 12-fiber MPO/MTP patch cord. A higher fiber count will support greater bandwidth and higher data transfer speeds, but it also comes with increased cost and size. Consider the future scalability of your network, as higher fiber counts allow for easier expansion.

3. Select the Right Fiber Type: Single-Mode or Multi-Mode

Another important consideration is whether to use single-mode or multi-mode fiber. The difference lies in the type of light transmission:

• Single-Mode Fiber: Designed for long-distance transmission, single-mode fiber uses a single light path, resulting in low signal loss over long distances. It is typically used in long-range connections, such as between buildings or across campuses. Single-mode MPO/MTP patch cords usually have a yellow-colored jacket.

• Multi-Mode Fiber: Used for shorter distances, multi-mode fiber has a larger core size, allowing multiple light paths for faster data transmission over short to medium distances. Multi-mode MPO/MTP patch cords are typically used in data centers and local networks and are marked with an orange or aqua-colored jacket, depending on the type of multi-mode fiber (OM1, OM2, OM3, OM4).

When choosing your MPO/MTP patch cord, make sure you select the correct fiber type (single-mode or multi-mode) that matches your network's needs.

4. Consider the Connector Type: Male or Female

MPO/MTP patch cords come in both male and female connectors. The primary difference between male and female connectors is the presence of pins inside the connector. Male connectors have pins, while female connectors have sockets. When selecting the correct patch cord, you need to match the type of connector required for your equipment or network components.

For instance, if your switch or equipment has a female MPO connector, you will need a male MPO patch cord, and vice versa. Ensure that your patch cords are compatible with the equipment you're connecting to avoid mismatches.

5. Check for Polarity: A, B, or C

Polarity is crucial in multi-fiber networks, as it ensures that the correct fiber connections are made. There are three main types of polarity configurations used in MPO/MTP systems:

• Polarity A (Straight-through): In this configuration, fibers in the MPO/MTP patch cord correspond directly from one end to the other, with no crossover.

• Polarity B (Crossed-over): This configuration swaps the fiber pairs at each end of the patch cord to ensure that fibers connect correctly for bi-directional communication.

• Polarity C (Harnessed): This method is typically used for high-density systems and involves the use of a harness that provides correct fiber-to-fiber mapping between ends.

It's important to choose a patch cord that is pre-configured with the appropriate polarity for your network setup. Some networks may require specific polarity configurations, so confirm with your installer or network engineer which configuration is required.

6. Check the Cable Length

The length of the MPO/MTP patch cord is another key factor. Patch cords come in various lengths, typically ranging from 1 meter to 30 meters. When selecting the length, make sure it is long enough to reach between network components without creating unnecessary slack or tension in the cables. However, avoid excessive lengths as they can lead to signal degradation and signal loss.

Measure the distance between the equipment where the patch cord will be connected and select the appropriate length. Always consider future flexibility when selecting cable lengths for your system.

7. Look for High-Quality Materials

For reliable performance, it’s important to choose MPO/MTP patch cords made from high-quality materials. Look for cords that are constructed with low-loss fibers and connectors made of durable materials like high-quality plastic or metal. Low-loss materials ensure better signal transmission, while durable connectors help ensure longevity and prevent damage from bending or wear over time.

Additionally, check for UL-rated cables to ensure safety standards are met. The build quality of the cable directly impacts the overall performance and lifespan of your network.

8. Consider Future Scalability

As your network grows, you may need to upgrade or expand your fiber infrastructure. When choosing MPO/MTP patch cords, consider future scalability. Opting for high-fiber count patch cords or higher-quality components now may save you time and money in the future when you need to expand your network. Planning for future upgrades allows you to avoid having to replace or add new components later on.

9. Assess Brand Reputation and Warranty

Choose MPO/MTP patch cords from reputable manufacturers who are known for their quality and reliability. Leading brands often offer solid warranties, excellent customer service, and technical support. Selecting a reliable brand can help ensure you get high-performance products that are backed by long-term warranty coverage. This way, you can feel confident that your investment is secure and that the patch cords will perform well over time.

10. Frequently Asked Questions (FAQs)

1. What is the difference between MPO and MTP connectors?

MPO (Multi-Fiber Push-On) is a generic term, while MTP is a specific, higher-performance brand of MPO connectors. MTP connectors offer improved features, such as higher pin precision and better durability, making them suitable for demanding applications.
