FDDI MEDIA SPECIFICATIONS

A.1

MULTIMODE FIBER OPTICS

•

Cable - The Multimode fiber optic link segments should consist
of either 50/125

µ

m, 62.5

µ

m, or 100/140

µ

m fiber optic

cabling.

•

Attenuation - Cable must be tested with a fiber optic
attenuation test set adjusted for an 850 nm wave length. This
test verifies that the signal loss in the cable is acceptable.

Attenuation limits for various Multimode cable types are listed
below:

-

3.0 dB or less for a 50/125

µ

m fiber cable segment.

-

16.0 dB or less for a 62.5/125

µ

m fiber cable segment.

-

19.0 dB or less for a 100/140

µ

m fiber cable segment.

•

Fiber Optic Budget -The fiber optic budget and total network
propagation delay should be calculated before fiber runs are
incorporated in any network design. Fiber optic budget is the
combination of optical loss of the fiber optic cable, in-line
splices, and fiber optic connectors. Propagation delay is the
time it takes a packet to travel from the sending device to the
receiving device.

•

Length - The maximum Multimode fiber optic cable length is
2 km (6558 feet), if system budgets are met. However, IEEE
802.3 FOIRL (Fiber Optic Inter-Repeater Link) specifications
specify a maximum of 1 km (3279 feet).
