IBM 8265: Planning and Site Preparation Guide
There are four basic types of optical fiber cables recommended for use in the IBM
Cabling System:
The specifications for Type 5 and Type 5 J cables are sufficiently detailed so that
ordering can be done without the need for additional information. The number of
fibers in Type 5 R and Type 5 OD cable is not fixed by specifications, nor is the
presence or absence of armor for Type 5 OD cable. This is due to the wide range of
fiber counts, environments, and installation requirements covered by these cables.
Since the tensile strength and the minimum bend radius are dependent on the size of
the cable, these specifications are also left open.
