Routing rules/examples
All break-out cables must be led through chambers 1 and 2, the 1.6 mm fibers through
chambers 3 and 4. The figures below show recommended cable routings depending on
the number of used subracks and ports.
NOTE:
The figures are valid for fiber top access (overhead structure). For fiber bottom
access (raised floor), the cabling has to be done similiarly (mirror-inverted only).
