CTP Cabling Recommendations
We suggest that you comply with the following recommendations:
- 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
device.
- Attach laser fiber connectors only to Class 1 laser devices
in accordance with IEC 60825-1, Safety of Laser Products - Part 1.
- Route cables so that they do not restrict ventilation
or airflow.
- Route cables so that modules and field-replaceable units
are easily accessible.
- Route cables in a logical direction to prevent loss of
connectivity to other equipment in the rack, associated equipment
in adjacent racks, or to the backbone network.
- Consider using cable-management brackets to keep network
cables untangled and orderly and to prevent cables from hindering
access to other slots.
