Advances in data centre-related infrastructure are largely driven by increased network demand for higher bandwidth, faster service and ubiquitous access. Because of these trends, very high fibre-count cables (more than 3,000 optical fibres) become essential for connecting hyperscale data centres within a campus over distances of less than 10km. Another application space that is currently a topic of active interest in the industry is metro data centre interconnect (DCI).

Corning has announced its newest singlemode optical fibre, Corning SMF-28 Ultra 200 fibre, which it claims is the industry’s first 200-micron fibre with a 9.2 micron nominal mode-field diameter (MFD). SMF-28 Ultra 200 fibre enables the design of smaller, lighter, fully backwards-compatible, high-fibre, high-density cables.
Network owners have much to consider when designing access networks. The network has to be able to support high-data rates and to maximise coverage area from the central office. Ideally, it should take advantage of low cost installation techniques and hardware miniaturisation. Once deployed, the network may have a lifespan of 15 to 20 years so upgrades to higher data rates must be supported. Finally, but not least, backwards compatibility is essential to ensure that new installations can be connected to equipment that has been already installed.
