With the demand for high-speed transmission and data capacity of 40G/100G network cabling in data centers, the application of high-density MPO/MTP fiber optic connectors and jumpers is becoming more and more common. MPO/MTP fiber optic connectors are multi-core connectors that provide multi-fiber connections in one connector, thus supporting higher bandwidth and higher density applications. So what is the difference between MPO and MTP?
MPO is "Multi-fiber Push On", which is the first-generation shrapnel-type multi-core connector developed by Japan's NTT Communication Company in the 1980s. MPO connectors are about the same size as normal SC connectors, but have several times the density. Usually, 12-core fibers can be arranged in one column, and one or more columns of fibers are supported in the same MPO connector. According to the number of cores arranged in the connector, they can be divided into one column (12 cores), multiple columns (24 cores or more), 400Gb can also be used in the arrangement of 16/32 cores. In this way, one MPO connector can realize the simultaneous transmission of 12-core or more optical fiber signals, which saves a great deal of space and resources for optical fiber cabling.
MPO Fiber Optic Connectors
MTP is a registered trademark of US Conec, which produces multi-core connector parts and ferrules, specifically called MTP connectors. Both MTP and MPO fiber optic connectors comply with the international standard "IEC-61754-7" and the American standard "TIA-604-5 (FOCIS5)", which to a certain extent shows that the two are compatible. The MTP fiber patch cord is a high-performance MPO connector with more optimized optical and mechanical properties. The appearance design is slightly different, but the two are interchangeable and interconnected.
MTP connectors are specially designed to improve performance and usability over MPO connectors. The main differences between the two are as follows:
1. The outer frame sleeve of the MTP connector is designed to be removable, which is convenient for users to reprocess and polish the MT ferrule and flexibly change the male and female.
2. The floating ferrule of the MTP fiber optic connector can improve the transmission performance during mechanical docking.
3. There is a metal pin clip inside the MTP fiber optic connector to fix the push ring, minimizing accidental breakage when mating with the connector
4. The oval guide pin (PIN) of the MTP fiber optic connector is made of metal material and oval design, which can maintain high-performance transmission for a longer time.
MTP connector features
MPO/MTP fiber optic connectors are small in size and high in density. They can support multi-core optical fiber connections, greatly save the space occupied by line ports and cables, so that higher-density wiring can be achieved in a certain space. The great flexibility and scalability also make cabling deployment simpler and more adaptable to the needs of future network upgrades, expansions and changes.
