5.4CABLE SPECIFICATIONS

The FDDI Physical Layer Medium Dependent (PMD), Twisted Pair Physical Layer Medium Dependent (TP-PMD), and Single Mode Fiber Physical Layer Medium Dependent (SMF-PMD) ANSI standards deﬁne cable requirements as follows:

Multimode Fiber	62.5 ∝m nominal
Core diameter:	62.5 ∝m nominal
Cladding diameter:	128.0	∝m maximum
	122.0	∝m minimum
Cable attenuation:	≤ 2.5 dB/km typical
Single Mode Fiber	8.7 ∝m +/- 0.5 ∝m
Core diameter:	8.7 ∝m +/- 0.5 ∝m
Cladding diameter:	127.0	∝m maximum
Cable attenuation:	≤ 0.5 dB/km typical

5.4.1Multimode Fiber Optic Cable Length

The PMD FDDI standard speciﬁes the following:

Maximum total cable length:	100 km (62 miles) — dual ring
	200 km (124 miles) — wrapped
Maximum multimode cable length
between adjacent nodes:	2 km (1.2 miles)

5.4.2Single Mode Fiber Optic Cable Length

The SMF-PMD FDDI standard speciﬁes the following:

Maximum total cable length:	100 km (62 miles) — dual ring
	200 km (124 miles) — wrapped
Single mode cable length
between adjacent nodes:	40 km (24 miles) maximum
	25 km (15 miles) typical
