Maximum Trunk Lengths

The maximum trunk cable length between the TRXI and another active device is equal to the Maximum Drive Distance as shown in Table 2-7. When the neighboring token ring device is a passive device, the combined length of twice the longest trunk cable plus the longest lobe cable attached to the passive ring segment cannot exceed the Maximum Drive Distance Trunk Length.

Attenuation

The fiber optic cable must be tested with a fiber optic attenuation test set that is adjusted for a 1300 nm wavelength. This test verifies that the signal loss in a cable is within an acceptable level of 10 dB or less for any given single mode fiber optic link.

Fiber Optic Budget

Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. When determining the maximum fiber optic cable length, the fiber optic budget (total loss of 10.0 dB or less between stations) should be calculated and considered before fiber optic cable runs are incorporated in any network design.
