Why Is Plenum Cable Important to High Density Data Centers?

In most terrible building or house fire disasters, combustible plastics (PVC) used in the wiring are always among the very things that contribute to the rapid spread of fire and toxic smoke. And the air conditioning systems even help the toxic smoke given off by the burning cables to spread throughout the building quickly. As for the high density data center with high speed computing equipment and large amount of plastic jacketed cables, it is crucial to take measures to reduce the damage in an unwanted fire. How to make the crucial data center a safer place? The high quality plenum cable (eg. MTP fiber) can be one of the best choices.

Plenum Cable for Data Center Environment

Plenum space is an area used for return of air circulation or air conditioning systems. In a data center, the spaces covered by the precision air conditioning unit are often necessary to deploy plenum products. They include not only plenum containment that separates cold aisle and hot aisle, but also plenum cables that meet the highest fire code requirements. Both electric cables and fiber optic cables are required to be plenum rated (CMP) when they are installed in inner walls and inner ceilings of data center buildings.

MTP Plenum Fiber: Get Safety and High Bandwidth at the Same Time

The integration of plenum jacket and MTP fiber is a perfect solution for high density data center applications. The safety feature of the plenum cable and the high fiber port count of MTP connector endow the data center with two essential components. By using MTP plenum cable, the possible danger that might be caused by cables located at cold aisle and hot aisle can be minimized when a fire incident occurs. In addition, the high bandwidth demands within a limited space in data center can be satisfied.

Use MTP plenum cable to get safety and high bandwidth at the same time.

When buying MTP fibers, be sure to check if it is genuine plenum rated and the MTP connector should meet the physical connection standard for acceptable insertion loss. When burnt, plenum cable will give off little smoke, and the color of the smoke is light instead of dark. FS MTP plenum cables are made of Corning fiber and U.S. Conec MTP connector. They are all tested and guaranteed by 3D interferometry and the insertion loss is no more than 0.35 dB. No matter it is the plenum jacket, the inner fiber, the connector, or the end face geometry, they are all genuine parts and in high quality. They can be checked by any user without a problem.

Things You Should Know About Ribbon Optical Cable

Local area network (LAN) campus and building backbones, as well as data center backbones, are migrating to higher cabled fiber counts to meet increasing system bandwidth needs. Ribbon optical cables are now being deployed to meet this need, as they provide the highest fiber density relative to cable size, maximize utilization of pathway and spaces and facilitate ease of termination. This article may provide some knowledge of ribbon optical cable.

Ribbon Optical Cable Design

Ribbon optical cable is now being widely used in campus, building and data center backbone applications where fiber counts of more than 24 are required. This kind of cable offers robust performance equivalent to the stranded loose tube cable. It provides the maximum fiber density relative to cable diameter when compared to stranded loose tube and tight-buffered cable designs. The cable design characteristically consists of 12 to 216 fibers organized inside a central tube. There are two kinds of jacket material for ribbon optical cable. Non-flame-retardant jacket material is often used in outdoor applications while flame-retardant outer jackets are used for indoor applications. Picture below shows a basic construction of ribbon optical cable.

MTP Connector Makes a Easy Ribbon Optical Cable Termination

For many years, people have been reluctant to use ribbon optical cable in the LAN and data center because 12-fiber ribbon field terminations were limited. With the introduction of field-installable 12-fiber array connectors, 12-fiber ribbons are easily terminated with simplex and duplex connectors such as LC or SC connectors or with the MTP connector. The MTP connector (shown in the picture below) is a 12-fiber push/pull optical connector with a foot-print similar to the SC simplex connector. These high-density connectors are used to significantly accelerate the network cabling process, minimize errors and reduce congestion in patch panels.

MTP connector
Today, the MTP connector is commonly available in preterminated form—as a pigtail to be spliced onto a 12-fiber ribbon, or as a MTP patch cord which is terminated on each end (shown in the picture below). Many end-users are now using preterminated cables where the cable is factory terminated with MTP connectors and/or simplex or duplex connectors to ensure the highest quality connector insertion loss and return loss performance and to expedite the cable installation.

Ribbon Optical Cable Greatly Saves the Pathway and Spaces

Optimal cabled fiber density in data-center pathway and spaces is important to facilitate efficient cooling systems as well as for removal of abandoned cable in accordance, so it’s essential to maximize use of pathway and spaces. Ribbon fiber cables offer up to 45 percent space savings, and three times the fiber-tray capacity over traditional bulkier cable solutions. At the same time, it also minimizes the cable tray weight.

Conclusion

Because the ribbon optical cable offers the highest fiber packing density to maximize pathway and space utilization in ducts and raceways as well as patch panels, it is now being deployed in areas where stranded loose tube and tight-buffered cable have historically been used. Fiberstore provide all kinds of ribbon optical cables (12 to 216 fibers) and MTP connectors, as well as MTP truck patch cables with low price and high quality.
