In order to meet the needs of high-density interconnection wiring in high-speed and large-capacity data centers, traditional single-core SC fiber connectors and dual-core LC fiber connectors are gradually replaced by high-density multi-core fiber connectors. At present, the multi-core optical fiber connector in the industry usually adopts MPO or MTP.
MPO is the abbreviation of Multifiber Push-On/Pull-Off in English, which means multi-core push-pull self-locking optical fiber connector, which was invented by USconec. MTP is the brand of MPO connectors registered by USconec, specifically referring to the high-performance MPO connectors it produces.
Compared with ordinary optical cables, the main features of MPO/MTP optical cables are high density and pre-connection, which are ultimately reflected in MTP/MPO multi-core connectors. Throughout the development of the industry, optical fiber connectors have two obvious development stages: the first stage is to save space and develop towards miniaturization. Optical fiber connectors have developed from traditional FC, ST, SC to LC, MTRJ.
In the second stage, not only to save space, but also to meet the requirements of multi-core use, the optical fiber connector has evolved from LC, MTRJ to MU, MTP/MPO. At present, one MTP/MPO multi-core connector can meet the high density requirements of 12-core, 24-core, 72-core, etc. More importantly, the MTP/MPO optical cable realizes the multi-core pre-connection of a single optical fiber through the equipment and assembly line in the factory, replacing the complex operation of on-site termination, which not only greatly reduces the on-site installation time, but also greatly reduces wiring. System installation space, while also reducing the impact of on-site construction and installation on performance and the probability of performance uncertainty.
MPO/MTP cable
To sum up, the advantages of applying MPO/MTP cables in data centers mainly include the following aspects
(1) To protect the effectiveness and safety of investment, although the application of MPO/MTP optical cable puts forward higher requirements for the integrators' early-stage and actual on-site investigation capabilities, it can also fully protect the investor's control over the project and the knowledge of the products used. right to avoid material waste and project investment risks;
(2) Economical and applicable, on the whole, the MPO/MTP pre-connection method does not add extra cost;
(3) It is easy to operate, easy to install, save installation time, and can be plug and play. We can make a simple comparison, such as laying 1 288-core optical cable, 3 construction workers, 2 sets of equipment, using the traditional fusion fiber method, it takes about 2 hours to lay, and the fusion fiber plus installation time takes about 8 hours, a total of about 10 hours, and if MPO/MTP pre-connected optical cables are used, the laying time is still 2 hours, but the installation time is greatly reduced, about 45 minutes, which undoubtedly has a huge advantage in time cost;
(4) The MPO/MTP pre-connected optical cable is fully tested in the factory, and no other products are attached during the installation process, and the field test operation is simple;
(5) The optical fiber link is fully protected, there is no splicing point and bare optical fiber is exposed to the air, and there will be no problems such as aging and joint breakage; (6) Maintenance is convenient and safe, and the mechanical properties of the MPO/MTP pre-connected optical cable splitter are very good. Excellent, the maintenance or operation process will not affect the normal use of the fiber;
(7) It can be re-installed and moved, the MPO/MTP pre-connected optical cable branch can be quickly plugged and moved, and re-installed as needed.
Although MPO/MTP optical cable brings many benefits in engineering implementation through end-to-end high-density integration and plug-and-play implementation, it is still necessary to measure whether it has the ability to support smooth network upgrades. We know that the cabling system of a data center cannot be used for only 5-10 years. Compared with network equipment, the life of the cabling system is much longer. Therefore, when planning the cabling system of the data center, it is necessary to consider future network upgrades and ability to expand. As the data center migrates from 10G to 100G, the traditional LC-type port connection method will not be able to adapt to demand, but MPO/MTP is more than capable.
Under the IEEE 802.3ba standard, MPO/MTP can realize 100G in two ways, namely: (1) In a 24-core MPO optical cable and connector, 10 cores are used for sending signals, and the other 10 cores are used for receiving signals, so that , 10 10G parallel optical links form a 100G optical link; (2) Among the two 12-core MPO optical cables and connectors, 10 cores of one MPO optical cable are used for sending signals, and 10 cores of the other MPO optical cable are used for sending signals. The core is used to receive signals. Similarly, 10 10G parallel optical links form a 100G optical link. Under the IEEE 802.3bm standard, an 8-core MPO optical cable and its connector can also be used to realize the parallel transmission of four 25G optical channels. In conclusion, MPO/MTP has good adaptability for network upgrade and expansion.
When choosing MPO/MTP optical cable, in addition to meeting the design requirements, the most important thing is to pay attention to whether the MPO/MTP optical cable manufacturer's factory complies with a series of quality management system certifications such as ISO 9000, and whether its production process and product performance meet The current industry standard certification for the production of fiber optic connection components. 100g.shop's MPO/MTP Cable, which meets the above purchase requirements, will be one of the first-choice cabling products for you to build a green and efficient data center.
