INDOOR-OUTDOOR OPTICAL FIBER CABLE
|Publication Date:||4 June 2019|
Indoor-outdoor cables covered by this Standard are generally derived from outdoor cable designs having the thermal and mechanical robustness that makes them suitable for use in the Outside Plant. Material changes are made, as required, to allow the designs to meet their intended fire rating. These cables are expected to comply with all specification requirements stipulated in this Standard.
In cases where outside exposure is limited (less than 10 meters), a weatherized cable may be derived from an indoor cable design (backbone or interconnect). As required in Annex B, the indoor cable weatherized for outdoor complies with the requirements found in ICEA S-83-596. The requirements specified in Part 1 through 8 do not apply, except as invoked by Annex B.
Cable that is compliant with S-104-696 is considered compliant to S-83-596.
All designs covered by this Standard are intended for operation under normal conditions found in the outside plant environment and in the communications user's premises. These products normally convey communications signals (voice, video, and data) from point to point or point to multi-point, within and outside buildings. Products covered by this Standard may be factory or field terminated with connectors or splicing modules.
Indoor-outdoor cables are generally used to make interconnections within and between adjacent buildings or to the first outdoor splice point. These cables are fully compatible in the typical outside plant environment, but their attenuation characteristics are not necessarily the same as Outside Plant Communications cables addressed in S-87-640. See Part 8 of this specification.
When a hybrid cable (a cable with both optical fibers and metallic conductors) is required, the applicable metallic conductor requirements shall be as established by agreement between the customer and the cable manufacturer. The requirements of ANSI/ICEA S-84-608 should be considered when determining appropriate requirements.
For 1625 nm fiber performance, see Annex C.
Use S-87-640 for general guidance in other special cases.
The normal temperature ranges for cables covered by this Standard are listed in Table 1-1:
The standard installation tensile rating for cables covered by this Standard is:
• ≤ 12 fibers 1335 N (300 lbs)
• > 12 fibers 2670 N (600 lbs)
The residual load is defined as a load equivalent to 30 percent of the rated installation load.
Minimum Bend Diameter
The standard minimum bend diameters for cables covered by this Standard are:
Loaded (During Installation):
20 x Cable OD
30 x Cable OD for ribbon cables greater than or equal to 216 fibers.
40 x Cable OD
Smaller cable bend diameters are permissible as agreed upon between the user and manufacturer.
Products covered by this Standard shall comply with the pertinent Fire Resistance Code(s) described in Clause 1.9.
1) Other limits may be applied by manufacturers to limit the long-term strain on composite strength members.
