MTP® Connector

What Is the MTP® Connector?

MTP® is the acronym for Multi-fiber Termination Push-on, which is a registered trademark of US Conec. The MTP® connector, also known as the MPO (Multi-fiber Push-On) connector, is a type of fiber optic connector widely used for high-density and high-speed data transmission applications. It is designed to accommodate multiple optical fibers within a single connector, allowing for efficient connectivity in data center and telecommunications environments.

Both MTP® and MPO fiber optic connectors comply with the international standard "IEC-61754-5" and the American standard "TIA-604-5 (FOCIS5)", which shows that the two are compatible to some extent. Although MTP®/MPO fiber optic connectors' dimensions are similar to ordinary SC connectors‘, the density of MTP®/MPO fiber cable connectors has increased several times compared with ordinary SC connectors, which can save a lot of space and resources for optical fiber wiring. The deconstruction of the MTP® cable connector is illustrated below.

MTP®：Technical Improvements of MPO Connector Components

MTP® (Multi-Fiber pull-out) is an improved version of the MPO connector, so the MTP® connector can be fully compatible with the general-purpose MPO connector and can be directly interlinked with the cabling system based on the MPO fiber jumper. However, compared to the generic MPO fiber jumper connector, the connector of the MTP® fiber jumper improves the optical and mechanical properties in the following covers.

• Spring Push: MTP® fiber jumper connectors are usually equipped with metal spring push to better hold the pin in place to greatly reduce accidental breakage during use, while MPO fiber jumper connectors are equipped with plastic spring push that may cause the pin to break when in use.

• Ferrule: MTP® fiber jumper connectors have ferrules that can be used to improve mechanical properties. In other words, the ferrules of the MTP® fiber jumper connector can float internally to maintain a stable connection even when a load is applied. However, the MPO fiber jumper connector has no floating ferrule.

• Pin Clamp: Unlike single-core fiber optic connectors, adapters for multi-core fiber optic connectors are only used for coarse alignment. Therefore, when using two MT rings together, the guide pin is essential for accurate alignment. MTP® and MPO fiber jumper connectors also use different guide pins, MTP® fiber jumper connectors are tightly fixed stainless steel circular guide pins to reduce debris on the guide hole and ferrule end face. The MPO fiber jumper connector uses a cylindrical guide pin, which may generate debris when used.

How to Clean MTP® Connectors?

To clean MTP® connectors, you can follow these steps

1. 1. Gather the Necessary Cleaning Supplies: You will need lint-free wipes specifically designed for fiber optic cleaning and a fiber optic cleaning solution. Make sure the cleaning solution is recommended for use with MTP® connectors.

2. 2. Inspect the Connector: Before cleaning, visually inspect the MTP® connector to check for any visible dirt, dust, or debris. If you notice any contaminants, they should be removed before proceeding with cleaning.

3. 3. Prepare the Cleaning Solution: Follow the manufacturer's instructions to prepare the fiber optic cleaning solution. It is important to use the recommended solution and avoid using alcohol-based cleaners as they may damage the connector.

4. 4. Wet the Cleaning Swab or Wipe: Moisten a lint-free wipe or cleaning swab with the cleaning solution. Be careful not to oversaturate the wipe.

5. 5. Clean the Connector End-face: Gently hold the connector and use the moistened wipe or swab to clean the end-face of the MTP® connector. Make sure to apply light pressure and avoid touching the fiber end-face directly.

6. 6. Wipe in a Straight Motion: Clean the connector end-face by wiping in a straight motion across the surface. Avoid circular or swirling motions, as they may cause additional contamination.

7. 7. Inspect the Connector After Cleaning: After cleaning, inspect the connector again to ensure that it is free from dirt or residue. Use a fiber inspection microscope or an end-face inspection tool to check for any remaining contaminants.

8. 8. Repeat If Necessary: If the connector is still not clean, repeat the cleaning process using a fresh cleaning wipe or swab. It is important to use a new, clean wipe for each cleaning to avoid cross-contamination.

Remember to handle the MTP® connector with care and avoid touching the exposed fiber end-face. Regular cleaning and inspection of MTP® connectors are essential to maintain optimal performance and prevent signal loss or disruptions.
