MTP and MPO fiber jumpers have connectors at both ends, which are insensitive to bending, carefully polished and low loss. They are very suitable for high-density wiring systems and cable management wiring that need to save space. The main difference between MTP and MPO fiber optic patch cords is their connector
How to distinguish between MTP and MPO fiber optic patch cords?
Although MTP fiber optic patch cords can be directly interconnected with the wiring system based on MPO fiber optic patch cords, MTP and MPO fiber optic patch cords are different in connector types, pin clamps, floating ferrules, guide pins, removable housings and performance. .
Connector type
The MPO (multi-fiber push-in) connector is a connector with at least 8 optical fibers. It is designed to provide multiple optical fibers in a connector. It conforms to the IEC 61754-7 standard and the American TIA-604-5 standard. Suitable for high bandwidth and high density wiring system connection.
The MTP (multi-fiber pull-out) connector is manufactured by US Connector and is an improved version of the MPO connector. Therefore, the MTP connector is fully compatible with the general MPO connector and can be directly connected with the MPO fiber patch cord Wiring system interconnection. However, compared with general MPO fiber optic patch cord connectors, MTP fiber optic patch cord connectors can improve optical and mechanical properties.
Pin clip
Connectors of MTP fiber optic patch cords are usually equipped with metal pin clamps, which can better fasten the pins to minimize accidental breakage during use, while MPO fiber optic patch cord connectors are equipped with plastic pin clamps. In use, the pins may break.
Floating ferrule
The connector of the MTP fiber jumper has a floating ferrule, which can be used to improve the mechanical performance. In other words, the floating ferrule of the MTP fiber jumper connector can float internally to maintain a stable connection under load. However, MPO fiber optic patch cord connectors do not have floating ferrules.
Guide pin
Unlike single-core fiber optic connectors, multi-core fiber optic connector adapters are only used for coarse alignment. Therefore, when using two MT ferrules together, the guide pin is essential for precise alignment. The guide pins used in MTP and MPO fiber optic patch cord connectors are also different. MTP fiber optic patch cord connectors are tightly fixed stainless steel circular guide pins to reduce debris on the guide hole and the end surface of the ferrule. MPO fiber optic patch cord connectors use cylindrical guide pins, which may generate debris during use.
MTP fiber optic patch cord connector has a removable shell
The MTP fiber jumper connector has a detachable shell, allowing users to rework and polish the MT sealing gasket, perform performance testing easily, and easily change its polarity even on-site after assembly. MTP PRO optical fiber jumpers can quickly and effectively configure cables and change polarity on site, while also ensuring product performance. For more information on how to change the polarity of the MTP PRO fiber patch cord, please refer to the MTP PRO fiber patch cord field tool instruction.
The MPO fiber optic patch cord connector has been recognized as an international standard for fiber optic cabling and is suitable for 40G/100G data center cabling structures. However, using MPO fiber optic patch cord connectors may cause some problems, such as return loss, packet loss, etc. The MTP fiber optic patch cord connector is a high-performance MPO connector designed to ensure the polarity of the fiber optic patch cord and help reduce the insertion loss and return loss when transmitting data in high-density cabling systems.
