Definitions

  • the present disclosure relates generally to structures for telecommunications cables, and more particularly, to cable demarcation racks.
  • optical networks there is no flexibility in panel, enclosure, cassette, or module size. Additionally, or alternatively, speed of deployment of optical networks is important for organizations to begin earning revenue from their capital expenditure. As such, some methods of deploying optical networks (e.g., splicing) require skilled labor and can be time consuming. For instance, splicing may take approximately 5 minutes per 12-fiber ribbon splice, which may inhibit deployment of fiber optic systems with thousands of fibers. Current applications utilize external (e.g., outside plant or OSP) enclosures, or internal structures to perform this splicing. An impact of the use of internal structures is that space available for revenue generating telecommunications equipment is utilized to perform the splicing. External enclosures may require a 'pit' and are liable to flooding, which may require remedial work that can be challenging, time consuming, and costly.
