Efficient fiber management has become a critical consideration with respect to data center architecture given the widespread adoption of fiber optic connectivity across hyperscale, co-location and telecommunication markets. Proper implementation of fiber management presents numerous benefits to data center operators with cost reduction being one of the more significant and sought-after.
Put simply, a Meet-Me Room (MMR), otherwise known as ENI (External Network Interface) or MDA (Main Distribution Area), is a relatively small but very important space inside a data center where internet service providers, telecommunications carriers, cable companies, etc. converge to interconnect or cross-connect with one another and exchange data before distribution of services to other areas of the building.
Single Mode (SM) and Multimode (MM) are the names given to two competing designs of optical fiber based on how many paths of light are transmitted along the fiber core – single mode, meaning “one path”, or multimode, meaning “more than one path.” A mode can be described as a “path” or “ray” of light in the core of the optical fiber.
Today’s business requirements are changing daily, and the infrastructure that supports those businesses needs to be equally dynamic. That means providing highly scalable connectivity infrastructure to enable the rapid integration and migration to next generation, higher speed, active equipment in your IT deployment.
This is a short and easy to read explanation of the CPR and how it applies to fiber optic cables and copper balanced cables. The Construction Product Regulation (CPR) (EU No.305/2011) provides regulatory rules by using a harmonized standard (EN 50575:2014/ A1:2016) for the “reaction to fire” of cables permanently incorporated into buildings and construction works.
Since the dawn of time, or at least since fiber optic cables were first produced in 1975, they have always been bundled in multiples of twelve fibers / tubes. Cable fiber counts were commonly 12, 24, 48, 96, 144, and recently all the way up to 6,912 (576 individual 12-fiber units).
All data centers are essentially buildings that provides space, power and cooling for network infrastructure. They centralize a business’s IT operations or equipment, as well as store, share and manage data. Businesses depend on the reliability of a data center to ensure that their daily IT operations are always functioning. As a result, security and reliability are often a data centers top priority.
When designing your network and physical data center infrastructure, basic concepts such as port densities, fiber volume, over vs under routing paths, and internal cabling specifications need to be carefully considered.
