Twisted Pair Cable Length
The TP-PMD FDDI standard specifies the following:
Maximum total
cable length:
100 km (62 miles) — dual ring
200 km (124 miles) — wrapped
Maximum twisted
pair cable length between
adjacent nodes:
100 m (328.1 feet)
Single 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
Power Requirements
The high bandwidth of FDDI means that FDDI MIMs consume more
power than Ethernet or Token Ring MIMs. Power requirements vary
from one FDCMIM-04 or FDCMIM-08 to another, depending on the
motherboard you have.
To determine your FDCMIM-04 or FDCMIM-08 power requirements:
•
Locate the serial number on the front panel of the FDCMIM.
•
Match the beginning of the serial number on the FDCMIM
with one of the following numbers.
Note: Depending on your FDCMIM version, you may have to preface
serial numbers with number 940. In other words, a serial number
beginning with 0568 is the same as one starting with 9400568.
