Differences Between MPO and MTP Fiber Optic Connection Standards

The Differences Between MPO and MTP Fiber Optic Connection Standards

With the rapid development of data centers and the gradual penetration of cloud computing and cloud storage applications into various industries, the bandwidth requirements for network communications have increased significantly. High-speed, high-capacity, and high-bandwidth solutions often require larger spaces and higher costs, presenting a long-term contradiction. The MTP/MPO fiber optic cabling standard has become the best solution for high-density and high-bandwidth needs. Currently, there are two fiber optic connection systems on the market: MTP and MPO. They are very similar and can be compatible to some extent. So, what are the differences between them?

What is an MPO Connector?

MPO (Multi-fiber Pull Off) is the first-generation spring-loaded multi-fiber connector designed by NTT Communications in Japan. Now, it is a name for multi-fiber connectors produced by several companies.

MPO stands for "multi-fiber pull off". This type of connector has more than one fiber core, which is mechanically latched into place.

Different manufacturers have various designs for MPO, leading to significant differences in performance and cost. Some products feature improved performance, and certain MPO connectors can match products from various brands, while others cannot. This compatibility depends on how close these connectors are to the standard design.

The complete definition of MPO connectors can be found in IEC-61754-7 and EIA/TIA-604-5 (FOCIS 5).

What is an MT Ferrule?

MT stands for mechanical transmission, with the ferrule usually having 12 fibers. The connector's performance depends on the precision of fiber alignment and whether this precision remains stable after connection. This alignment precision is ultimately determined by the fiber's eccentricity and spacing, as well as the matching accuracy of the guide pin and fiber. Improving the precision of guide pins and molding processes during manufacturing can enhance any MPO connector's performance.

What is an MTP Connector?

MTP is a high-performance MPO connector with multiple innovative designs, offering enhanced optical and mechanical performance compared to typical MPO connectors.

MTP connectors meet all professional standards for MPO connectors, including EIA/TIA-604-5 FOCIS 5 and IEC-61754-7.

Why is the MTP Connector Described as a High-Performance MPO Connector?

The specially designed MTP connectors improve performance and usability over standard MPO connectors. These unique design features are patented. Key features include:

1. Removable Housing:The outer housing of MTP connectors can be easily removed. This feature ensures performance stability during manufacturing rework and re-polishing. The gender can be flexibly changed even after assembly, and the ferrule can pass interference testing after assembly.

2. Floating Ferrule:The floating ferrule design improves transmission performance during mechanical connection. This allows the ferrules of two connectors to maintain good physical contact under external forces.

3. Elliptical Guide Pin:MTP connectors use elliptical stainless steel guide pins, enhancing alignment precision and reducing wear on guide holes, thus maintaining high-performance transmission over time.

4. Metal Pin Clip:MTP connectors have a metal pin clip that secures the push ring. This design prevents the loss of guide pins, centralizes the pressure from the spring, and prevents the spring from contacting and damaging the fiber during mechanical compression.

5. Spring Design:The spring design of MTP connectors maximizes the ribbon gap for 12-fiber and multi-fiber applications, preventing fiber damage.

6. Multiple Adapter Kits:MTP connectors come with at least four standard matching adapter kits, making them suitable for various types of optical cables. These include:

• Loose tube round cable

• Oval jacketed ribbon cable

• Bare fiber ribbon

• Ultra-short tail adapter kit, suitable for narrow spaces, reducing volume by 45%.

Practical Applications

The MTP/MPO fiber optic connection standard is widely used in data centers, high-speed networks, and other environments where high-density and high-bandwidth connections are required.

Summary:The differences between MPO and MTP fiber optic connection standards are crucial for understanding their applications in modern high-density, high-bandwidth networks. While MPO connectors provide a versatile and standardized solution, MTP connectors offer enhanced performance and usability due to their unique patented design features. These improvements make MTP connectors an ideal choice for demanding environments requiring reliable and high-performance optical connections.
