How is MTP produced?

Under normal circumstances, a tight-buffered multi-core fiber requires skilled technicians to terminate both ends. The advanced version of the MTP patch cord adopts the pre-termination method, with MTP connectors at both ends, which can accommodate multiple optical fibers. These pre-terminated MTP jumpers are currently the most common with 12 cores and 24 cores, which can meet up to 72 cores. They are divided into two types: male (with pins) and female (without pins). The emergence of MTP technology meets the requirements of large-capacity optical fiber systems and is an ideal choice for data centers to achieve high density and high performance.

The traditional LC wiring system has long been unable to meet the high transmission rate and high density requirements in large data centers, so some IT designers turn to MTP wiring solutions. This wiring scheme is different from LC wiring and can perfectly adapt to the requirements of high-speed, high-density and structural wiring. It has the following advantages:

1. Stable and durable

2. High density and expandable

For example, the LC duplex connection in a 1U chassis can accommodate 144 fibers, while the MTP can accommodate 864 fibers, which is nearly six times the number.

3. Save time and worry, high deployment efficiency

If plug-and-play pre-installed cables are used, the entire installation process will greatly shorten the time, and it will save time and worry, and the subsequent maintenance costs will be lower.

4. Prepare for the network upgrade

MTP cabling can be used for direct connection of 40G-40G, 100G-100G, 200G-200G, 400G-400G, as well as upgrade and uplink connection. It is very common to use MTP cabling system 10G to upgrade to 40G/100G/120G, and it is an economical and reliable choice to upgrade 10G network to higher speed Ethernet. At the same time, the uplink connection between devices of different speeds can also be achieved through MTP cabling systems, such as 25G-100G, 50G-200G/400G, 100G-400G, 200G-400G.

5. Structured rack cabling

MTP structured cabling provides a hierarchical structure for the network, and multiple connection schemes will be provided through the convergence layer, which can reduce the problem of cable clutter. When the data center needs to expand in the future, a long-term solution can be built by installing a structured MTP cabling system.


MTP jumper products: diverse needs, multiple choices

The MTP wiring series have a wide range of products that can meet the needs of different applications, including MTP jumpers, MTP distribution boxes, and MTP-LC branch cables:


1.MTP trunk jumper

The MTP backbone patch cord is composed of an optical cable and connectors at both ends. It can be used to connect optical modules to form a complete link. It can usually accommodate 8, 12, 16, 24, 32, 48 or even 72-core optical fibers, which fully meets Requirements for high-density wiring. There are two main applications: one is for direct connection of optical modules, such as connecting 40GBASE-SR4/PLR4, 100GBASE-SR4/SR10, 200GBASE-SR8 and 400GBASE-SR8, and the other is for wiring boxes and panels. Realizing structured cabling helps to quickly deploy backbone networks in high-density environments.


2.MTP branch jumper

One end of the MTP branch jumper is equipped with an MTP connector, which can be branched into multiple LC connectors. The number ranges from 4, 6, 8 to 12. The connector types can be LC, SC, ST, etc., and multi-core jumpers can be used. The line transfer is a simplex or duplex connector. MTP branch jumpers are divided into single-mode and multi-mode. The transmission distance can be extended from a few meters to a longer distance. It is an ideal choice for 10G-40G, 25G-100G, and 10G-120G network conversion.


3.MTP conversion jumper

The MTP conversion jumper adopts fan-out design like the MTP branch jumper, but both ends are connected to MTP connectors. The number and types of fiber cores of the connectors at both ends are different, providing a variety of connection possibilities for the 24-core wiring system, which can realize 24 cores to 2*12 cores, 24 cores to 3*8 cores, and 3*8 cores to 2* 12 cores and many other applications.


4.MTP adapter and MTP adapter panel

MTP adapter is a supplementary product of MTP fiber optic patch cord. There are two types according to the key direction: key up-key up and key up-key down. Both types of adapters are suitable for the connection between MTP jumpers or between jumpers and equipment, which are very common in backbone wiring and distribution box applications. The MTP adapter panel can accommodate more adapters and is an upgraded structure with a safety board. By pre-installing the adapter, the adapter panel can act as an intermediate medium between the backbone network and the jumper, thereby providing a more stable and compact network solution.


5.MTP optical fiber distribution box

MTP optical fiber distribution box is a closed box structure, generally there are 12 or 24 optical fibers inside, with LC or other types of connectors at the front, and MTP connectors at the rear, which can divide the optical fibers of the backbone cable into duplex jumpers. line. The MTP distribution box is matched with the rack to quickly deploy high-density data center infrastructure, and can perform troubleshooting and reconfiguration during management.


7.MTP-LC rack mount adapter panel

The 96-core pre-terminated MTP-LC rack-mount adapter panel can be installed on a 19-inch wide patch panel, so the 96-core optical fiber can be directly deployed in a 1U rack without additional equipment. When you need to deploy 10G-40G or 25G-100G connections, you can use MTP jumpers to connect the 40G/100G switch port to the rear port of the panel, and then use the duplex LC jumper to connect the 10G/25G device to the front of the panel. The port is fine. The rear of this MTP-LC rack-mount adapter panel has a flexibly removable cable management panel, which greatly simplifies the trunk cable management, helps to improve installation efficiency and optimize cable layout.


Conclusion

Obviously, with the deployment of 40G/100G/200G/400G data center networks, high speed and high density have become a trend, and traditional LC cabling can no longer meet the demand. However, the MTP cabling scheme caters to this trend, paving the way for the construction of high-performance data center networks with its advantages of time-saving, space-saving, and cost-saving, as well as superior stability and high density. There is no doubt that MTP wiring solutions and MTP wiring components are the best choice for data interconnection and high-speed migration.
