The basic overview of the MTP branchable fiber optic jumper It is a single fiber optic assembly containing several jackets, located in the outer jacket. This is different from bundle type cables where the tightly wrapped fibers are bundled together and only the outer cable jacket of the cable protects the fibers. Branchable cables are designed with strengthening devices for added strength, but the cables are larger in size and more expensive than bundled type cables. Branchable optical cables are suitable for short-distance information services and conference applications, as well as pipeline applications, so the laying method is simple and does not require any junction boxes or copper wires for splicing optical fiber connections.
Advantages of branchable fiber optic cable, branchable fiber optic cable is composed of several single optical fibers twisted on a central member and assembled separately in a sheath. This is different from bundle type cables where several tightly packed optical fibers are collected and wrapped in the same jacket. Branchable optical cables are widely used and suitable for flame retardant, non-toxic and smokeless flame retardant but smoke indoor applications. Can be used on framed or horizontal bridges. Each fiber is individually strengthened, so it is also possible to divide the branchable fiber optic cable into individual fiber optic lines. This enables fast connection of terminals and does not require a terminal block. Branchable cables are more economical because they can save a lot of labor when connecting to terminals. You may choose a cable with more fibers than you actually need to allow for breakage when connecting to the terminal or for future expansion.
At present, there are mainly two types of multi-core connectors, MTP and MPO. The differences are as follows:
The integrated branch optical cable is composed of seven sub-cables. It depends on the size of the branch to decide which method to use.
The sub-cables have loose tube and tight tube structures. The number of cores of the loose tube sub-cable is usually not more than 24 cores, and the central tube structure is adopted. The number of cores of the sub-cable with tight sleeve structure is usually not more than 12 cores, and the outer diameter of the sub-cable is generally not more than 6mm, that is, the diameter of the integrated branch cable is not more than 20mm. In 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 color bars can be used on the outside to distinguish different sub-cables. The second form of the sub-cable is plated steel wire, and the loose sleeve is still used inside, and the outside is adjusted according to the user’s requirements for the sub-cable. The middle of the sub-cable with tight-buffered structure is a tight-buffered optical fiber, and the outer yellow one is spun fiber. The sub-cable with tight-buffered structure can be made smaller than the loose-buffered structure, which is more suitable for use in FTTH.
