Details of MTP/MPO Cables
MTP/MPO cables arecomposed of MTP/MPO connectors and fiber optic cables, other connectors such asLC may also be found in some kinds of MTP/MPO cables. The fiber cables used aregenerally OM3 and OM4, which are laser optimized multi-mode optical fibers. Itis important to have an overall understanding of MTP/MPO connectors (known asmulti-fiber push-on and also as multi-path push-on).

MPO connectors are available in a female version (without pins), or a maleversion (with pins) as shown in the following picture. The pins ensure theexact alignment of the fronts of the connectors, and also they ensure the endfaces of the fibers are not offset.
Noses and guidegrooves (key) on the top side are the two other clearly visible features, whichensures the adapter hold the connector with the correct ends aligned with eachother. Based on the placement of the key, two types of MPO adapters areavailable. One is “key-up to key-down”. It means the key is up on one side anddown on the other. The two connectors are connected turned 180° in relation toeach other. The other one is “key-up to key-up”. It means both keys are up. Thetwo connectors are connected while in the same position in relation to eachother.
- Always use one male connector and one female connector plus one MPO adapter when creating a MPO connection (see the following picture).
- Never connect a female to a female or a male to a male. It should be connected with a male and a female as stated above. With a female-to-female connection, the fiber cores of the two connectors will not be at the exact same height because the guide pins are missing. That will lead to losses in performance. A male-to-male connection has even more disastrous results. There the guide pins hit against guide pins so no contact is established. This can also damage the connectors.
- Never dismantle a MPO connector. The pins are difficult to detach from a MPO connector and the fibers might break in the process. In addition, the warranty becomes null and void if you open the connector housing.
MTP/MPO Cable has the advantages of shorter installation times, tested and guaranteed quality and greater reliability. It has several different kinds of types.
Trunk cables serve asa permanent link connecting the MTP/MPO modules to each other. They are available with 12, 24, 48 and 72 fibers. Their ends are terminated with 12-fiber or 24-fiber MTP/MPO connectors according to customer's choice. These trunk cables like 12 fibers MPO trunk cable could help to create a simple,cost- effective 40G networking by installing a structured cabling system. MTP/MPO trunk cable requires greater care in planning but has a number of advantages, such as higher quality, minimal skew, shorter installation time,better protection, smaller volume of cable and lower total costs.
Harness cables provide a transition from multifiber cables to individual fibers or duplex connectors. For instance, 8 fibers 12 strands MTP/MPO harness cable has eight LC high fiber density connectors and a MPO connector, which is convenient for wiring and management system in 40G network with stable performance.
Y cables are generally used in the 2-to-1 version. A typical application is to join two 12-fiber trunk cables to a 24-fiber patch cord as part of a migration to 100 GbE. The rather rare version of 1 to 3 allows three eight-fiber MTP/MPO connectors to be joined to a 24-fiber permanent link, e.g. for migration to 40 GbE.
MTP/MPO Solutions for 40 Gigabit Ethernet Cabling
OM3 and OM4 fiberoptic cables put in a parallel optical connection, terminated with MTP/MPOconnectors. These are the ingredients for 40 GbE technology in a structuredcabling environment. Parallel optical channels with multifiber multimodeoptical fibers of the categories OM3 and OM4 are used for implementing 40 GbE.The small diameter of the optical fibers poses no problems in laying the lines,but the ports suddenly have to accommodate four or even ten times the number ofconnectors. This large number of connectors can no longer be covered withconventional individual connectors. So the 802.3ba standard incorporated theMPO connector for 40GBASE-SR4.
MTP/MPO connectorsand cables are the central components of a 40G parallel optical link. Thisconnection decides whether the insertion loss exceeds the attenuation budgetand whether the return loss is high enough. In the end, the desired bandwidthcan only be reached if all components in a parallel optical link satisfy thehighest requirements.
