Isolation Recommendations
Publication 1756-TD008A-EN-P - August 2002
The cable installation should conform to all applicable codes.
In order to successfully apply the concepts and
IMPORTANT
techniques contained in this manual, you must have
a fundamental knowledge of electronics and
electrical codes.

Cable Protection

The fiber optic cable must be properly handled prior to and during
installation. Improper handling may result in cable damage and
require cable replacement. Use the following guidelines when
handling the fiber optic cable:
· Keep the cable ends tightly sealed during storage,
transportation, and installation of the cable. Keeping the cable
ends sealed will prevent exposure to moisture or other foreign
matter.
· Do not exceed the minimum bend radius of the cable during
storage or installation. Refer to Appendix B for cable
specifications. Bending the cable sharper than the recommended
minimum bend radius may decrease the reliability of the
SynchLink.
· Prevent the cable from contacting abrasive surfaces such as
concrete.
· Follow the cable pulling recommendations specified in sections
Chemical and Thermal Isolation and Physical Isolation.

Chemical and Thermal Isolation

The fiber optic cable must be protected from damage caused by:
· Oil, grease, acids, caustics, and other harsh and/or hazardous
chemicals that might damage the cable jacket and connectors.
· Water, steam, and other liquids.
· Open flame, steam lines, and any equipment with the
temperature higher than the cable operating temperature.
