Fiber enclosures are junction points for structured cabling systems. They are very beneficial as they allow for rapid changes that happen frequently in the data center.
How do fiber enclosures work?
Typically fiber enclosures, also referred to as “patch panels,” are located at the top of a rack. A large bundle of cables will run under the floor or in overhead conveyance, and plug into the back of the fiber enclosure. Within the fiber enclosure are couplers. These couplers allow cable connectors to “mate,” or meet up. This is the critical component of the fiber enclosure. This allows for the rapid change out with use of a short “jumper” or patch cable to run from the equipment up to the fiber enclosure.
Benefits of fiber enclosures in a structured cabling system
Fiber enclosures are particularly helpful when installing new networking equipment that calls for a connector change. For example: say your data center is hooked up network cables that have SC connectors, but a new switch calls for network cables with an LC coupler. Instead of having to remove cables from underfloor or overhead conveyance and install entirely new cables with LC connectors, only the cable connecting the enclosure to the switch needs to be replaced. This not only vastly decreases installation time, but also reduces the risk of network downtime, as you’re not removing and replacing large amounts of cabling.
As a part of a structure cabling system, fiber enclosures play a critical role in effective cable management that reduces installation, creates easier moves, adds and changes, and decreases the chance for network downtime.







Yesterday I wrote a little bit about
When fiber cable assemblies stop working properly, it can lead to downtime. In the next few posts I will explain how and why this actually happens. This will be broken into two parts: How it happens at the end user site, and how it occurs at the manufacturer level.
