MPO/MTP system solutions are steadi-ly gaining in significance. Data centers in particular have a great need for compact and flexible plug-and-play systems that are pre-measured and preterminated at the factory. MPO/MTP system solutions allow users to achieve complete end-to-end cabling in keeping with the new standard for data centers. In the IEEE 802.3 standard, 40 Gb/s and 100Gb/s were defined with MPO connector technology. The crucial factor is the insertion loss and return loss of the components. Controlled production processes and ultra-precise end-face geometry are needed to satisfy these tough requirements. With the MPO/MTP multi-fiber system, a data center is well-equipped for future transmission rates of 40 and 100Gb/s.

Benefits of deploying modular, high-density optical solutions, such as MPO-based connectivity (including MPO trunk assemblies, breakout modules and breakout harnesses) in a structured wiring architecture include 50% cable-tray space savings, 80% improvement in deployment time, and 70% bulk-cable reduction in cabinets and racks. A modular, high-density solution deployed in a structured wiring topology can easily scale to hundreds of thousands of ports and significantly reduce the time to conduct MACs in the data center, thus reducing operational costs.

So now, we have the means to cope with future growth and churn in the data center. Now, let’s address the issue of keeping this modular high-density structured cabling system in place to handle future higher-data-rate applications.

In addition to manageability and scalability, a benefit to deploying a modular, high-density MPO-based cabling system is the available migration path to increased data rates. With some consideration of performance specifications, the infrastructure can easily migrate to future higher-data-rate technologies, such as parallel optics, which will be used in 32-, 64-, and 128-Gigabit Fibre Channel; and 40- and 100-Gigabit Ethernet. In fact, by deploying an optical cabling system that meets InfiniBand 12X-QDR (120-Gbit) cable skew performance requirements of = 0.75 ns and distance specifications, the same infrastructure that is carrying serial transmission today can be easily migrated to transmit parallel-optic InfiniBand signals.

To mitigate this issue and increase the lifecycle of an optical-cabling infrastructure, deploy high-quality low-loss optical components. Low-loss MPO trunks, breakout harnesses, modules and jumpers minimize channel insertion loss and enable the cabling infrastructure to easily migrate to future higher data rates.

For example, 8-Gbit Fibre Channel will support a distance of 100 meters using OM3 fiber and a connector budget no greater than 2.4 dB. If an MPO mated pair has a maximum insertion loss of 0.5 dB, and each MTP-to-LC breakout module wasspecified at a maximum insertion loss of 0.75 dB, then theresulting maximum connector loss in the channel will be 2.75 dB.

This exceeds the recommended maximum 2.4 dB connector loss budget of 8-Gbit Fibre Channel at 100 meters, thereby reducing the supportable distance at 8-Gbit Fibre Channel; however, if low-loss components were specified into the same cable plant at 0.5-dB maximum insertion loss per MTP-to-LC breakout module and 0.35-dB maximum per MTP mated pair, then the resulting maximum connector loss in the channel will be 1.85 dB, providing support of 8-Gbit Fibre Channel beyond 100 meters.

As previously discussed, TIA-942 addresses the use of ZDAs as part of the recommended topology for datacenters. Implementing a distributed zone solution reduces pathway congestion and facilitates the implementationof MACs common in the data center environment. Implementing a zone topology can increase the number of connection points in a given channel. Using components with low-loss performance enables zone connectivity without sacrificing distance capabilities due to channel insertion loss.

Additional methods to implement zone distribution with reduced channel insertion loss include using components that are optimized for the architecture. Solutions that offer a combined MPO-based trunk assembly and breakout module can eliminate connector pairs while still offering the flexibility of zone cabling, thereby reducing total channel insertion loss. Now we introduce some MTP/MPO assemblies when you are solving MTP/MPO system.

MTP high density cabling solutions utilizes MPO (multi fiber push on) ferrule providing connection of 12 or 24 fibers. MTP provides superior physical and optical characteristics than standard MPO for precision alignment with spring loaded mechanism and guide pins. They have a removable adaptor that mates female connectors to a male connector with specially designed guide pins for orientation and maintaining polarity along the channel. The Micro-core cables used in factory terminated MTP fiber cable assemblies give 65% reduction in cable size from traditional fiber cables. Pre-connected MTP solution with 24 core LC duplex adapters offers 72 LC terminations in 1U rack space and 288 LC terminations in 4U rack space using modular patch panels.

MTP Patch Panels are scalable modular which are designed for high density Gigabit Ethernet Applications.They are used for terminating backbone cables at the Main Distribution Area (MDA) and Horizontal Distribution Area (HDA). MTP Patch Panels are available with 1U and 4U, suitable for standard 19” racks. 1U MTP Patch Panel can accommodate up to three MTP Cassettes, giving a high connectivity of 72 LC fiber terminations in it. 4U MTP Patch Panel can accommodate up to 12 MTP Cassettes, resulting in a maximum of 288 LC terminations per panel.
