The difference between MTP and MPO

2022-11-03 16:11:03

Basic overview of MTP branchable fiber optic patch cord It is a single fiber optic assembly with several jackets, located in the outer jacket. This differs from bundled-type cables where the tightly packed fibers are bundled together and only the outer cable jacket of the cable protects the fibers.


Drop-off cables are designed with strength-enhancing devices added, but the cables are larger in size and more expensive than bundled-type cables. The branchable optical cable is suitable for short-range information service and conference applications, as well as pipeline applications, so the laying method is simple, and no connection box or copper wire for splicing optical fiber splicing is required.

The advantage of the branchable optical cable is that the branchable optical cable consists of several single optical fibers stranded on a central member and individually assembled in a sheath. This differs from bundled-type cables where several tightly packed fibers are gathered and wrapped in the same jacket. Branchable cables are widely used and are suitable for flame retardant, non-toxic and smokeless flame retardant but smoky indoor applications.


Can be used on framed or horizontal decks. Each fiber is individually reinforced, so branching cables can also be split into individual fiber lines. This allows for quick terminal connection and eliminates the need for a patch panel. The branchable fiber optic cable is more economical, because it can save a lot of labor when connecting to the terminal. You may choose a fiber optic cable with more fiber than you actually need to allow for breakage when connecting to a termination or for future expansion.


At present, there are mainly two types of multi-core connectors: MTP and MPO. The differences are as follows:

1. MPO (Multi-fiber Push On) is a type of MT series connector. There are two different standards for MPO: the international standard is: IEC-61754-7, and the American standard is TIA-604-5 (FOCIS5).

2. MTP is a brand of MPO optical fiber connector produced and registered by US Conec Company in the United States. The multi-core connector parts and ferrules it produces are specially called MTP connectors.

3. There are many manufacturers of MPO fiber optic connectors with different brands.


The integrated branch optical cable is composed of seven sub-cables, and it depends on the size of the branch to decide which method to use.


The sub-cable has the form of loose sleeve and tight sleeve structure. The number of cores of the loose sub-cable is usually not more than 24 cores, and the central tube structure is adopted. The number of sub-cable cores in the tight-sleeve structure is usually no more than 12 cores, and the outer diameter of the sub-cable is generally no more than 6 mm, that is, the diameter of the integrated branch optical cable is no more than 20 mm.


The middle of the sub-cable is a loose-tube optical fiber, which can be reinforced with spun fiber or glass fiber on the outside, and different sub-cables can be distinguished by color bars on the outside. The second form of the sub-cable is plated with steel wire, and the inside is still loose, and the outside is adjusted according to the different requirements of the user for the sub-cable. The sub-cable of the tight-sleeve structure is a tight-sleeve optical fiber in the middle, and the outer one is a yellow fiber. The sub-cable of the tight-sleeve structure can be made smaller than the loose-sleeve structure, and is more suitable for use in FTTH.
