2.1.1 Fiber Optic Requirements

The fiber optic link segments should consist of single mode 8/125 - 12/125 μm fiber optic cabling. You can also use multi mode 62.5/125 μm fiber optic cabling, but signal distance will be much shorter (about 2 km).

The link segment 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 -10.0 dB or less for any given single mode fiber optic link.

When determining the maximum fiber optic cable length, the fiber optic budget and total network propagation delay should be calculated and taken into consideration before fiber runs are incorporated in any network design. Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Propagation delay is the amount of time it takes a packet to travel from the sending device to the receiving device. If the total propagation delay

between any two nodes anywhere on the network exceeds 25.6 μs, then you should use bridges.
