Switch Cascading in Topology•••• Takes the Delay Time into AccountTheoretically, the switch partitions the collision domain for each port in switchcascading that you may up-link the switches unlimitedly. In practice, the networkextension (cascading levels & overall diameter) must follow the constraint of theIEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in whichthe limitations are the timing requirement from physical signals defined by 802.3series specification of Media Access Control (MAC) and PHY, and timer from someOSI 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 FiberRound trip Delay: 4096 Round trip Delay: 512Cat. 5 TP Wire: 11.12/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/mFiber Cable : 10.10/m TP to fiber Converter: 56Bit Time unit : 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01μs (1sec./100 Mega bit)Table 2-2Sum up all elements’ bit-time delay and the overall bit-time delay ofwires/devices must be within Round Trip Delay (bit times) in a half-duplex networksegment (collision domain). For full-duplex operation, this will not be applied. Youmay use the TP-Fiber module to extend the TP node distance over fiber optic and
