TIA TIA-758-A Document Information:
Title
Customer-owned Outside Plant Telecommunications Infrastructure Standard
Telecommunications Industry Association
Publication Date:
May 5, 2004
Scope:
Applicability
This Standard specifies minimum requirements for customer-owned OSP
telecommunications facilities
in a campus environment. This standard specifies the cabling, pathways
and spaces to support the
cabling.
Customer-owned OSP cabling extends between separated structures
including the terminating
connecting hardware at or within the structures. The OSP pathway
includes the pathway through the
point of entry into the building space. Customer-owned OSP pathways
may include aerial,
direct-buried, underground (e.g., duct), and tunnel distribution
techniques. Customer-owned OSP
pathways and spaces specified by this Standard are intended to have a
useful life in excess of
forty (40) years.
The OSP cabling specified by this Standard is intended to support a
wide range of applications
(e.g., voice, data, video, alarms, environmental control, security,
audio, etc.) on commercial,
industrial, institutional and residential sites. The customer-owned
OSP cabling specified by this
Standard is intended to have a useful life in excess of thirty (30)
years.
This standard applies to all campuses, regardless of the size or
population.
Customer-owned OSP cabling infrastructure
Pathways and spaces
Many types of pathways and spaces may be required to route cabling
between campus buildings,
structures, or outdoor telecommunications pedestal or cabinets. Figure
1 illustrates a variety of
customer-owned OSP pathways and spaces. There are two basic types of
cable pathway systems:
underground and aerial (with exceptions for surface, above ground,
conduit following the route of
another above ground utility).
Underground pathways and spaces may be dedicated for cable placement
(e.g., direct-buried cable;
buried duct/conduit; maintenance holes; handholes; shared spaces such
as a utility tunnel providing
other services).
Aerial pathways and spaces may consist of poles; messenger wire;
anchoring guy wires; splice
closures and terminals. Self-supporting cables, which include a
messenger wire, may also be used.
Customer-owned OSP cabling
Customer-owned OSP cabling consists of recognized cable terminated
with conforming connecting
hardware and protective devices, as required. Customer-owned OSP
connecting hardware may be located
on the exterior or interior of a building, or in an outdoor
telecommunications pedestal or cabinet.
Figure 2 illustrates a typical OSP cabling layout.
NOTES
1 - The customer-owned OSP link can have intermediate splices (e.g.,
reducing a copper twisted-pair
feeder cable to distribution cables).
2 - Optical fiber cables may pass through a building entrance facility
as a part of the cable
route. For example figure 2 shows a cable from building "C" passing
through the building "A"
entrance splice point location to the destination at the outdoor
telecommunications pedestal "D".
