How to distinguish between fiber optic jumper MTP and MPO

In order to meet the network requirements of high-density integrated cabling, fiber optic jumpers are divided into two categories: MTP and MPO. However, many people do not understand how to distinguish between the two. Below, the editor will discuss this topic.
MTP and MPO have connectors at both ends, which are insensitive to bending, carefully polished, and have low loss characteristics, making them very suitable for high-density cabling systems and cable management cabling that require space saving. The main difference between MTP and MPO fiber jumpers lies in their connectors.
How to distinguish between fiber optic jumper MTP and MPO?
Although MTP fiber patch cords can be directly interconnected with MPO fiber patch cord based cabling systems, MTP and MPO fiber patch cords differ in connector types, pin clamps, floating grommets, guide pins, detachable enclosures, and performance.
Connector type
MPO (Multi Fiber Push in) connector is a connector with at least 8 fibers designed to provide multiple fibers in one connector, compliant with IEC 61754-7 and TIA-604-5 standards, making it ideal for connecting high bandwidth and high-density cabling systems.
MTP (Multi Fiber Pull out) connectors are manufactured by US Connector and are an improved version of MPO connectors. Therefore, MTP connectors are fully compatible with general-purpose MPO connectors and can be directly interconnected with MPO fiber patch cord based cabling systems. However, compared to conventional MPO fiber optic jumper connectors, MTP fiber optic jumper connectors can improve optical and mechanical performance.
Pin clip
MTP fiber optic jumper connectors are typically equipped with metal pin clips to better secure the pins and minimize accidental breakage during use, while MPO fiber optic jumper connectors are equipped with plastic pin clips that may cause pin breakage during use.
Floating ring
The connector of MTP fiber optic jumper has a floating collar, which can be used to improve mechanical performance. In other words, the floating collar of the MTP fiber optic jumper connector can float internally to maintain a stable connection even under applied loads. However, MPO fiber optic jumper connectors do not have floating grommets.
Guided sales
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 crucial for precise alignment. The guide pins used in MTP and MPO fiber optic jumper connectors are also different. MTP fiber optic jumper connectors are tightly fixed stainless steel circular guide pins to reduce debris on the guide holes and collar end faces. MPO fiber optic jumper connectors use cylindrical guide pins, which may generate debris during use.
The MTP fiber optic jumper connector has a detachable housing
The MTP fiber jumper connector is equipped with a detachable housing, allowing users to reprocess and polish the MT sealing gasket for easy performance testing, and even change its polarity on site after assembly. MTP PRO fiber optic 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 MTP PRO fiber jumpers, please refer to the MTP PRO fiber jumper field tool instructions.
performance
MPO fiber optic jumper connectors have been recognized as the international standard for fiber optic cabling, suitable for 40G/100G data center cabling structures. However, using MPO fiber optic jumper connectors may cause some issues such as return loss, packet loss, etc. The MTP fiber optic jumper connector is a high-performance MPO connector designed to ensure the polarity of fiber optic jumpers, helping to reduce insertion and return losses when transmitting data in high-density cabling systems.
