ICEA S-87-640 Document Information:
Title
Optical Fiber Outside Plant Communications Cable
Insulated Cable Engineers Association Inc.
Publication Date:
Sep 1, 2006
Scope:
Products
This Standard covers optical fiber communications cable intended
for outdoor use and normally installed aerially, directly buried,
or placed in underground ducts. Additional requirements for
"figure-8" aerial self-supporting cables are included in Annex
D, as appropriate. Materials, constructions, and performance
requirements are included in the Standard, together with applicable
test procedures. Refer to other published ICEA (ANSI/TIA) code
product standards for information on fiber optic cable requirements
for other applications:
• S-83-596: Optical fiber premises distribution cable
(ANSI/TIA-472C000-B)
• S-101-696: Indoor-outdoor optical fiber drop cable
(ANSI/TIA-472E000)
• S-110-717: Optical fiber drop cable (ANSI/TIA-472F000)
Applications Space
Products covered by this Standard are intended only for
operation under conditions normally found in communications
systems. These products normally convey communications signals
(voice, video, and data) from point-to-point or
point-to-multi-point, external to buildings. Products covered by
this Standard may be factory terminated with connectors or splicing
modules.
When a composite cable is required, the applicable metallic
conductor requirements shall be as established by agreement between
the end user and the cable manufacturer. The requirements of
ANSI/ICEA S-84-608 should be considered when determining
appropriate requirements.
Temperature Ranges
The normal temperature ranges for cables covered by this
Standard are given in Table 1-1
For the purpose of this standard, very-low temperature
applications, are defined as -50 °C (-58 °F) per 1.4.1.6, and are
addressed in Annex C (Normative), which contains requirements for
lower operating and storage temperatures than listed in Table
1.1.
Tensile Rating
The standard installation tensile rating for cables covered by
this Standard is 2670 N (600 lbf). Higher tensile ratings are also
acceptable for use. For applications where a lower tensile rating
is approprite the standard lower tensile rating is 1330 N (300
lbf). In all cases, the residual load is defined as any load less
than or equal to 30 percent of the installation tensile rating.
For self-supporting aerial applications there are additional
considerations that need to be addressed to ensure that the cable
design is appropriate for the self-supporting distance and
environmental loading conditions. See 7.30 and Annex D for
information on figure-8 self-supporting aerial cable requirements
and considerations.
For aerial applications in which the optical cable is lashed to
a separate messenger wire, the use of a cable designed for a
standard tensile rating for installation by direct burial,
trenching, or pulling into duct may be adequate.
Minimum Bend Diameter
The standard minimum bend diameters for cables covered by this
Standard are:
Residual (Installed): 20 x Cable O.D.
Loaded Condition (During Installation): 40 x Cable O.D.
For very small cables, such as those installed in miniature
ducts, manufacturers may specify a fixed cable minimum bend
diameter (e.g., 300 mm) that is independent of the cable outer
diameter (OD).
For cables not having a circular cross-section, bend diameter
requirements are to be determined using the thickness (minor axis)
as the cable and bending in the direction of the preferential
bend.
