The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber
100Base-TX TP
100Base-FX Fiber
Round trip Delay: 4096
Round trip Delay: 512
Cat. 5 TP Wire:
11.12/m
Cat. 5 TP Wire:
1.12/m
Fiber Cable:
1.0/m
Fiber Cable :
10.10/m
TP to fiber Converter: 56
Bit Time unit : 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01
μ
s (1sec./100 Mega bit)
Table 2-2
Sum up all elements’ bit-time delay and the overall bit-time delay of
wires/devices must be within Round Trip Delay (bit times) in a half-duplex network
segment (collision domain). For full-duplex operation, this will not be applied. You
may use the TP-Fiber module to extend the TP node distance over fiber optic and
provide the long haul connection.
