Cabling Recommendations
Use only shielded cables.
Ensure that cable distance and rate limits meet IEEE-recommended maximum
speeds and distances for signaling purposes. For information about attenuation
and power loss in optical fiber cables see:
ANSI T1.646a-1997 Telecommunications – Broadband ISDN - Physical Layer
Specification for User-Network Interfaces Including DS1/ATM (1997)
ANSI T1.646-1995 Telecommunications – Broadband ISDN - Physical Layer
Specification for User-Network Interfaces Including DS1/ATM (1995)
Ensure that power cables deliver sufficient power to the system.
Attach laser fiber connectors only to Class 1 laser devices in accordance with
IEC 825-1, Safety of Laser Products - Part 1.
Route cables so that they do not restrict ventilation or airflow.
