With high speed data transmission demand in data centers, traditional fibre patch cords cannot meet the connection requirements, now we should need high density and better store more data in a limited space. However, the normal connector SC FC LC ST can not meet such request, so there were MTRJ, E2000 or MU connectors, and during these 10 years, MPO/MTP connectors are more popular.
MTP cable can support 8, 12, 16, 24, 48, 72or even 96 cores of fiber optic connections, which can definitely meet the high-density transmission requirements of 40G, 100G, and 400G fiber optic networks in data centers.
MTP MPO Fiber Patch Cable Structure
MTP to MTP fiber cable are multi core fiber optic cable with MTP connectors at both ends. MTP fiber connectors are composed of optical fibers, cable sheaths, coupling components, metal rings, pins, dust caps, etc., guide pins are divided into male and female types, both are different from the MT ferrule. There are 2 guide pins with diameter 0.7mm at top of the MT ferrule for MPO male connector, white 2 guile holes for the MPO female connector. And MTP optical fiber connectors is mating precisely and aligned through the two pins, one side is MPO male connector, the other side is MTP female connector.
Fiber polarity of MPO/MTP® Patch cable
- Type A (straight-through): the alignment key of the MTP connectors are opposite – key up to key down.MTP patch cable fiber at both ends are in the same sequence, fiber 1 at one end to fiber 1 at the other end, and fiber 12 at one end to fiber 12 at the other end.
- Type B (Crossed) : the alignment key of the MTP connectors are the same- key up to key up or key down to key down.The cable MTP fiber sequence at both ends are arranged in the opposite position, fiber 1 at one end to fiber 12 at the other end, and fiber 12 at one end to fiber 1 at the other end.
- Type C (crossed in pair): the alignment key of the MTP connectors are the same position- key up to key up or key down to key down, but adjacent fiber sequence are crossed in pair. That means the fiber 1 at one end to the fiber 2 at the other end, fiber 2 at one end to fiber 1 at the other end; and 11 to the fiber 12 at the other end, and fiber 12 to the fiber 11 at the other end.
MTP Cable Types
MTP patch cord
MTP Trunk cable, generally longer and used between cabinets.
MTP breakout able
usually shorter, with splitter, used for connector conversion
MTP conversion cable
usually 0.3 meter, use in MTP cassette module or cabinets
MPO/MTP Cable Adavantages
- MTP connectors docking through adapter by the guide pins and guide holes which can eliminate docking errors and save installation time than single fiber connectors, excellent optical and mechanical properties, low insertion loss for high-speed network.
- MTP truck cable and MTP cassette module is easy to plug and unplug, adjusting the fiber capacity, saving labor cost and instruction time.
- MTP patch cord are multi-cores patch cords, so it can largely increase the density of optical fiber wiring through patch panels, cassette modules and special mounting plates, minimizing the space occupied by wiring.
- MTP cables can be ribbon or bundle micro cable, large capacity, small volume, high density with best bending radius.
- MTP fiber optic cable, fiber type, patch cord length can be customized, which is the preferred medium for 40G 100G 400G transmission network.
- According to different configuration requirements, you can find the suitable MTP fiber termination, such as MTP to MTP patch cable, MTP to LC breakout cable, MTP patch panel, MTP truck cable, MTP cassette, etc.
MPO MTP Cable Application
At present, MTP to MTP fiber cable are mainly used for data center room wiring. With the release of the new Ethernet 40G/100G standard of IEEE 802.3ba in June 2010, the high-speed transmission of 40G and 100G will not only rely on the extremely expensive WDM transmission of single-mode, but also adopt the multi-channel parallel transmission of OM3 and OM4 multi-mode fibers. Compared with the single mode WDM transmission, the overall cost of this multi-mode parallel transmission method in 40G/100G is only 1/3 and 1/10 of the single-mode system, which shows that the cost advantage of multi-mode is very obvious.
Precautions for using MTP patch cord
1. Ensure that the MPO patch cords are not knotted, bent, entangled, stretched or squeezed.
2. Regularly check whether the fiber patch cords have creases and connector damage.
3. Accurate labeling is required on the wiring infrastructure, no matter it is patch cord, cassette or the wiring panel.
4. Since optical fiber is very fragile, the outer sheath of the optical cable and Kevlar are used as the reinforcing core and protective layer. If the wrapping of the MTP fiber patch cords is too tight, the optical cable will be deformed or even press the optical fiber inside. The deformation of the optical fiber will increase the attenuation.
