Products

Cables covered by this Standard include two classes of cables using single-mode fiber. The cables are for use in single or multi-dwelling units (MDU) or other FTTX applications where fiber is delivered to the end customer equipment.

The first class, the rugged drop cable class, may be stapled, routed around corners under tension, and coiled in a tight diameter. Examples include the Rugged Indoor Drop or Indoor/Outdoor Rugged Drop.

The second, less robust compact class of drop cable may consist of an indooronly or indoor/outdoor rated cable. These cables are routed through an aesthetic duct or a similar less rigorous routing path without staples or bends under tension. Examples include Compact Drop or Small Form Factor Compact Drop.

The first class of cable are cables that usually terminate at the customer electronics, or Optical Network Terminal (ONT). The second class includes cables used for distribution and delivery of optical fiber from a demarcation point starting at a conventional optical fiber cable, optical fiber splitter or active optical device. However, either class of cable could be used for any of these applications, depending upon how the cable is installed and protected.

Fiber mechanical reliability requires that a cable classified as rugged shall meet the enhanced mechanical reliability requirements set forth in this document. See Clause 1.4 for a more detailed definition of these cable types.

Cables containing multimode fibers are not covered by this standard. Cables using multimode fibers should follow the intent herein using optical limits given by ICEA 596 as appropriate. Limits for specific tests not defined in ICEA 596 are to be agreed between manufacturer and user.

Application Space

All designs covered by this Standard are intended for operation under normal conditions found in the communications user's premises; the indoor/outdoor designs may also be used in a limited outdoor environment, such as attached to the outside of an Multiple Dwelling Unit (MDU) or other building. These products normally convey communications signals (voice, video, and data) from point to point or point to multipoint. These cables are intended for use from a local distribution point on or within a building to single or multiple units throughout a building. Products covered by this Standard may be factory terminated with connectors or splicing modules.

Tensile Rating

The standard installation tensile ratings for cables covered by this Standard are:

• Small Form Factor Indoor Compact Drop 40 N (9 lb)

• Indoor Compact Drop 220 N (50 lb)

• Indoor Rugged Drop 440 N (100 lb)

• Indoor/Outdoor Rugged Drop 440 N (100 lb)

• Indoor/Outdoor Compact Drop 220 N (50 lb)

The residual load is defined as a load equivalent to 30 percent of the rated tensile installation load.

Minimum Bend Diameter

The Standard minimum bend diameter for cables covered by this standard, unless otherwise specified, is in accordance with ICEA 596 interconnect cable specifications. For cables that are not round, the bend diameters are calculated using the minor dimension.

For rugged drop cables, either a 10 mm or 15 mm bend diameter specification shall be used as agreed between user and manufacturer. Specific test requirements exist in Subclause 7.25. It is understood that the cable may act as a self-bend-limiter to provide mechanical protection for the fiber.

Fire Rating

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