scope:

This Standard covers performance requirements for limited power hybrid copper and fiber communications cables intended for use in the buildings, or for short distances external to the building of communications users. The optical fiber is intended for communications use while the copper conductors are intended for limited power applications in accordance with Articles 725 and 805 of the National Electric Code (NEC) ANSI/NFPA 70. Typically, these cables utilize conductor sizes that range from 10 AWG to 24 AWG. Generally, these cables are limited to a maximum of 100 VA. However, refer to NEC document for detailed requirements. Materials, constructions, and performance requirements are included in the Standard, together with applicable test procedures.

Products covered by this standard are intended only for operation under conditions normally found in communication systems. Typically, these products are installed both in exposed areas (surface mounted to walls or building baseboards or in non-stationary configurations) and in concealed areas (within walls, attics, etc.), with or without external protection (such as conduit), depending upon product type and specific use. These products normally convey communications signals (voice, video, data, etc.) from place to place within a building. Products covered by this Standard may be factory terminated with connectors or splicing modules.

This standard is intended to serve as a reference to the most recent appropriate standards: ICEA S-83-596 for optical fiber communications cables intended for indoor use, ICEA S-104-696 for optical fiber communications cables intended for indoor-outdoor use and UL13 for Power Limited Circuit Cables with the addition of any additional requirements to ensure a functional cable design.

This standard is written from the application perspective of a Distributed Antenna System (DAS); however, other use cases that involve hybrid fiber/copper in a Limited Power application as defined by the National Electric Code, are considered to apply.

Standard Minimum Bend Diameter

Unloaded Condition (Installed):

20 x Cable OD

Loaded Condition (During Installation):

40 x Cable OD

For very small cables, 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 diameter and bending in the direction of the preferential bend.

Products covered by this Standard shall comply with the pertinent Fire Resistance Code(s) described in 1.9.
