B andwidth demand continues to skyrocket on multibuilding campuses such as hospitals, corporate centers, government facilities, universities and large apartment complexes. To support high-speed data requirements – for example, transferring radiology image fles, ofering massive online courses or adopting cloud-based services – owners are deploying high-count fber backbones. However, they don't always know what their future needs will be or which functions will be located in each building. Tus, they require systems that are easily accessible and reconfgurable to suit current and future needs. "Tese types of fber installations are becoming very popular because everyone is certain of two things: First, supporting the typical user means accommodating higher bandwidth demands. Second, changes in the network confguration are inevitable," says Dr. Ian Timmins, vice president of engineering for enterprise connectivity products at Optical Cable Corporation (OCC). Timmins explains that in most current situations, campus networks are based on high- count fber optic backbone cabling systems. Architectures with fber counts of 144 and 288 are not uncommon, and installations with even higher numbers are emerging. Unfortunately, high-fber-count cables with large outside diameters are infexible and hard to manage and install. Tis poses the risk of broken fbers and jeopardizes the success of a system. In addition, connectivity devices make use of stacks of splice trays that feed adapter plates with extremely high fber counts – and this can make an infrastructure very challenging to service. Executing moves, adds and changes becomes a complex and difcult task. According to OCC, conventional solutions intended to overcome this challenge may result in too many connectors in the communications channel. Tis increases attenuation (optical loss), leading to decreased bandwidth and degradation in signal integrity. Manipulating stacks of splice trays to access a single fber can disrupt an entire network every time service is performed. Ultimately, this can make a conventional network architecture prone to disruptions, increased maintenance costs and premature system overhauls. A BLADE-LIKE APPROACH OCC's Blade Solution, its newest addition to the Procyon family of high-density connectivity and structured cabling solutions, ofers a diferent approach. Te Blade provides fexible cable subgroups that keep installers from damaging fber during the installation process as well as a connectivity system that provides easy access High-count cables with large diameters tend to be infexible and hard to manage and install.
