How to distinguish MTP and MPO optical fiber jumper

What is MPO fiber optic connector?

MPO is the abbreviation of multi fiber push on in English. It is the first generation of multi-core fiber connector designed by NTT company in Japan.

MPO optical fiber cable is composed of multi-core optical cable and corresponding 4 / 8 / 12 / 24 / 48 core high-density MPO. This product can provide male or female MPO models, and can choose various specifications of 4 ~ 48 core single-mode and multi-mode optical cables. At present, 12 core MPO connector is widely used. The compact design of MPO connector makes the number of MPO jumper cores small. MPO jumper is widely used in the environment of high-density integrated optical fiber line in the process of wiring, FTTx, 40 / 100gsfp, SFP + and other transceiver modules or equipment internal and external connection applications, MPO commonly used 8-12-24 core.

What is MTP fiber optic connector?

MTP is the abbreviation of multi fiber termination push on in English. It is the MPO fiber connector brand produced and registered by us conec company in the United States. Its multi-core connector parts and plug-in are specially called MTP connectors. Compared with the general MPO connector, MTP optical fiber connector has been enhanced in both optical and mechanical properties. It is a high-performance MPO connector with multiple innovative designs.

Why is MTP connector described as a high performance MPO connector?

Through the special design of MTP connector, its performance and availability are improved compared with MPO connector. This design feature of MTP is unique and patented. The main features are as follows:

1. The outer frame of MTP optical fiber connector can be easily removed.

The design of MT insert can ensure no loss of performance during rework and regrinding in production. The Yin and Yang properties can be changed flexibly even in the field after assembly, and interference detection can be carried out after the plug assembly.

2. The floating insert of MTP optical fiber connector can improve the transmission performance during mechanical docking. Two connectors can be allowed to keep good physical contact with each other under the influence of external force.

3. The elliptical guide pin (PIN) of MTP optical fiber connector is made of stainless steel. The elliptical guide pin can improve the docking accuracy and reduce the wear of the guide hole, so that the MTP optical fiber connector can maintain high-performance transmission more persistently.

4. The MTP fiber connector has a metal pin clip to hold the push ring.

5. The spring design of MTP optical fiber connector maximizes the band gap between 12 core and multi-core ribbon applications to prevent fiber damage.

6. MTP optical fiber connector has at least four kinds of standard matching parts, which can adapt to different types of optical cables, which is more practical, including circular optical cable with loose sleeve structure, ribbon optical cable with elliptical outer cover and bare ribbon fiber.

Where are MTP connectors optimized

1. The pin pin of MTP connector is stainless steel ellipsoid, which can improve the alignment accuracy and reduce the wear of guide hole. In the traditional MPO connector, although the pin pin is chamfered, the table top of the pin is still sharp. Repeated insertion and extraction will make the end face near the guide hole crack or damage, and then affect the stability of the connector insertion loss.

2. The spring design of MTP fiber connector maximizes the band gap of multi-core ribbon fiber application, so as to prevent fiber damage. In addition, there is a groove on the fixing clip of the guide pin of the MTP connector, which can fix the spring in the groove and center the spring force.

3. MTP connector is designed with guide pin fixing clip to prevent guide pin from losing.

4. The outer frame of MTP connector can be removed. The advantages of this method are: convenient rework and grinding of MT plug in production to ensure no discount of performance; convenient polarity of MTP connector, which can be flexibly changed after production and assembly; interference inspection of plug assembly.

5. The MTP connector allows the MT core to float in the outer frame, which improves the mechanical properties. In this way, when two MT are inserted, a certain external force will not change the physical contact of the two end faces, and the optical performance will not deteriorate as far as possible.

How to distinguish MTP and MPO optical fiber jumper?

Although MTP fiber jumpers can be directly interconnected with MPO fiber-optic jumper based cabling systems, MTP and MPO fiber jumpers differ in connector type, latch clip, floating ferrule, guide pin, removable housing and performance.

Connector type

MPO connector is a connector with at least 8 optical fibers, which is designed to provide multiple fibers in one connector. It conforms to IEC 61754-7 standard and tia-604-5 standard, which is very suitable for high bandwidth and high-density cabling system connection.

MTP connector can be fully compatible with general MPO connector, and can be directly interconnected with the cabling system based on MPO fiber jumper.

Latch clip

The connector of MTP optical fiber jumper is usually equipped with metal pin clip, which can better fasten the pin, so as to minimize the accidental fracture during use. However, MPO fiber jumper connector is equipped with plastic pin clip, which may cause pin breakage during use.

Floating ferrule

The connector of MTP fiber jumper has floating ferrule, which can be used to improve mechanical performance. The floating ring can float internally to maintain a stable connection under load. However, MPO fiber jumper connectors do not have floating ferrule.

Guide pin

MTP and MPO fiber jumper connectors use different guide pins. MTP optical fiber jumper connectors are tightly fixed stainless steel round guide pins to reduce debris on the guide hole and ferrule end face. MPO optical fiber jumper connector adopts cylindrical guide pin, which may produce debris during use.

Removable housing

The MTP optical fiber jumper connector has a detachable case, which enables users to re process and polish the MT sealing gasket, and can easily conduct performance test and change its polarity after assembly and even on site. MTP Pro optical fiber jumper can quickly and effectively configure cables and change polarity in the field, and also can ensure the product performance.

Performance

MPO optical fiber jumper connector has been recognized as the international standard of optical fiber wiring, which is suitable for 40g / 100g data center wiring structure. However, the use of MPO fiber jumper connector may cause some problems, such as return loss, packet loss and so on. MTP optical fiber jumper connector is a kind of high-performance MPO connector, which aims to ensure the polarity of optical fiber jumper and help to reduce the insertion loss and return loss when transmitting data in high-density cabling system.
