One Solution: Hyperscale Use Case

A Data Center Manager for a well know provider, needs to pull a 3456-f OSP All-dielectric cable through an existing 2” conduit. Time to install and labor costs are an issue but he wants to make sure that savings are not realized at the expense of network integrity. She also knows that the overall infrastructure needs to maximize the floor space available and be as easy to use and flexible as possible, especially the racks and cabinets; if the past is any judge, there will be MAC’s in his future.
