Optical networking the best choice for horizontal subsystems, report says

IT is becoming more important to the operational efficiency of businesses, making the underlying architectures that make effective technological solutions possible integral to a business' ongoing success. According to a recent Cabling Installation and Maintenance report, the rising prominence of IT is creating an environment in which the cabling infrastructure that enables communication in data center and operational settings is critical.

Because cabling is becoming a primary consideration at all levels of IT deployment, the structured cabling core existing within the horizontal subsystem is especially key to how a business establishes its IT footprint. The report explained that choosing the right setup for the horizontal subsystem can be extremely challenging, as it requires a complex interweaving of solutions that need to not only be compatible within this foundation, but also with with other elements of the network.

According to the news source, fiber-optic cabling infrastructure is the closest thing to a perfect solution for organizations establishing their horizontal subsystem. Fiber stands out, initially, because of its robust performance capabilities and capacity to transmit data over an extended distance. Furthermore, organizations that use fiber in their underlying infrastructure can deploy circuits that reach directly to the access network and end users, making it much easier to deploy other aspects of the cabling setup.

While fiber offers these considerable advantages, the report said it also presents significant challenges because of the relationship between singlemode and multimode solutions. Independently of each other, multimode is ideal for providing a high-performance, but inexpensive foundation for short distance deployments within the horizontal subsystem and similar deployments. Singlemode cables, on the other hand, are best used for extended deployments, such connecting buildings in a distributed campus. Because of the inherent mode differential, deploying the two cables together requires media conversion or similar solutions to ensure compatibility.

While the need for media conversion can be viewed as one of the few drawbacks of using fiber-optic cable infrastructure in horizontal subsystems, it is also one of the key enablers. Through media conversion tools, businesses can streamline network deployment by allowing for the use of whichever cabling systems and network protocols they want throughout the deployment. This is ideal for companies that want to achieve the best price-to-performance ratio, as it lets them use inexpensive copper solutions where possible, without sacrificing the key gains offered by fiber as the primary backhaul infrastructure.

Perle has an extensive range of Managed and Unmanaged Fiber Media Converters to extended copper-based Ethernet equipment over a fiber optic link, multimode to multimode and multimode to single mode fiber up to 160km.
