2-1-3-3. Switch Cascading in Topology
••••
Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch
cascading that you may up-link the switches unlimitedly. In practice, the network
extension (cascading levels & overall diameter) must follow the constraint of the
IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which
the limitations are the timing requirement from physical signals defined by 802.3
series specification of Media Access Control (MAC) and PHY, and timer from some
OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.
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:

TP to fiber Converter: 56
Bit Time unit : 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01
