With multi-fibre plugs to the high-speed network
For parallel optical data transmission, the MTP®/MPO connector currently is one step ahead. This connector should be the first choice for all those who rely on parallel optics and want to remain flexible in the future when migrating higher data rates. However, the major disadvantage of the MTP®/MPO connector is its high sensitivity to dirt. As a consequence, acceptance measurements cannot be done without any difficulty without suitable MTP®/MPO tools, such as video microscopes and measuring instruments, and without the corresponding know-how.
There are various approaches to eliminate the risk factor of contamination and to make this connector system more robust against contamination. In this context Rosenberger OSI relies on the quality features PreCONNECT® PURE and PreCONNECT® LOTUS. PreCONNECT® PURE protects the front surfaces of the FO - connectors by sealed fiber optic connection interfaces on the trunk cables and thus guarantees an absolutely clean delivery and installation. The LOTUS coating, on the other hand, acts like the effect of the same name in nature: The contact points are dirt, moisture and grease-repellent and thus offer the highest possible level of cleanliness.
Lens connector systems - an alternative?
Another approach to minimize the risk caused by dirt is the use of multi-fiber lens connector systems. Examples include the MXC® from USCONEC or the 3M™ EBO (Expanded Beam Optical) Latch Connector. Lens technology offers the great advantage of a particle of dirt causing a significantly lower insertion loss (IL) compared to an MTP®/MPO connector system. The reason for this is obvious: With an expanded beam, the area occupied by the dirt particle is significantly smaller.
