To meet the needs of today’s serial Ethernet applications, MPO-terminated backbone/horizontal cabling is simply installed into pre-terminated modules, panels or harnesses.Ĭabling migration from 10G to 40G to 100G in an MPO-based system is a simple and easy deployment. Using MPO-based connectivity in today’s installations provides the means to migrate to this multifiber parallel-optic interface when needed.Ī plug-and-play system incorporating factory-terminated MPO connectivity, as shown here, may include pre-terminated modules, panels and harnesses to meet the needs of serial Ethernet applications.įactory-terminated MPO solutions allow connectivity to be achieved through a simple plug-and-play system. In addition to the performance requirements discussed, the choice in physical connectivity is also important.īecause parallel-optics technology requires data transmission across multiple fibers simultaneously, a multifiber (or array) connector is required. In addition to being the only multimode fibers included in the 40G and 100G Ethernet standard, OM3 and OM4 fibers provide the highest performance as well as the extended reach often required for structured cabling installations in the data center. Within this architecture, the cabling is installed between the main distribution area and the equipment distribution areas.įor optimized performance in meeting data center requirements, the topology of the cabling infrastructure should not be selected alone infrastructure topology and product solutions must be considered in unison.Ĭabling deployed in the data center today must be selected to support data rate applications of the future, such as 100G Ethernet, Fiber Channel ≥32G and InfiniBand ≥40G. The TIA-942 Telecommunications Infrastructure Standard for Data Centers specifies a topology in which horizontal distribution areas are collapsed into the main distribution area. In this collapsed architecture, the cabling is installed between the MDA and the equipment distribution areas (EDAs). Many data center deployments today use the reduced topology described in TIA-942 where the horizontal distribution areas (HDAs) are collapsed into the main distribution area (MDA). Using a distributed star topology in a structured cabling implementation provides the most flexible and manageable infrastructure. Recommended cabling infrastructure deployments in the data center are based on guidance found in TIA-942 Telecommunications Infrastructure Standard for Data Centers.
