  • Page 17 REQUIREMENTS/SPECIFICATIONS MAXIMUM CABLE LENGTH Two cable lengths are defined for the repeaters, Lobe Length and Trunk Length. Lobe Length - The lobe length is the physical length of the cable connecting a station to its TCU port at the repeater. Table 2-3 shows the maximum lobe length, according to ring speed for each repeater.

  • Page 22: Trunk Cable Lengths

    • Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors (the loss for each splice and connector is typically 1 dB or less). • Propagation delay is the amount of time it takes a packet to travel from the sending device to the receiving device.
