1. General

This specification covers the design requirements and performance standards for the supply of optical fiber cables as described below.  The features described in this document are intended to provide information on the performance of 4SProducts optical cable and aid in handling and installation.

1.1    Cable Description

The Indoor Intrabulding cables contain 2 to 48 optical fibers; designed for premises applications where small size, excellent transmission properties and flame retardancy are required.

1.2    Quality

To meet ISO 9000 standards.

1.3    Reliability

Both initial and periodic qualification testing are performed to assure the cable's performance and durability in the field environment.

To meet and/or exceed industry standards organizations such as Telecommunications Industry Association (TIA),  International Telecommunications Union (ITU), International Electrotechnical Commission (IEC).

2. Cable Design

2.1 General

The design consists of tight-buffered fibers (900 µm) within a flame retardant PVC jacket.

 

2.1.1 Construction

For 2 to 12 fiber cables, individually color coded fibers and aramid yarn are bundled within the flexible jacket. Cables with more than 12 fibers are assemble in sub-groups and these are then put together to form the final cable.

BUFFER TUBE COLORS TUBE No. COLOR 01 Blue 02 Orange 03 Green 04 Brown 05 Slate 06 White

2.4 Sub-Group Tubes

Cables with more than 12 fibers are assembled in sub-groups and these are then put together to form the final cable.

2.5 Central Strength Member

Epoxy/Glass Rod for cable with more than 12 fibers.

2.6 Overall Strength Member 

Aramid fiber yarns.

2.7 Cable Sheath

Flame-retardant Polyvinyl Chloride (PVC):

• Yellow Jacket – Single-Mode fibers

• Orange Jacket – Multi-mode fibers
