Domain Calculations Rules of thumb while inexact may be helpful in planning network topology As a rule of thumb a Class II Repeater has a PDV of about 90 to 95 BTs and twisted pair or fiber www GarrettCom com 36 Magnum 14E Media Converters Installation and User Guide 10 02 media has a PDV of about 1 BT per meter of length The Magnum 14E has a PDV of 20 BT Therefore in shared Fast Ethernet applications the 14E uses about 80 meters of equivalent cable distance to convert from TX media to fiber FX media i e it consumes almost as much of the available PDV as a Class II repeater Since a 512BT collision domain will almost always include at least one repeater and two media segments the remaining amount of Bit Times left after allowing for a 14E and a length of fiber media indicates that the available fiber length will be much less than the 412 meters that is the known maximum for fiber Therefore in shared environments Magnum 14E Media Converters will be of benefit when they allow the use of fiber media but not to gain distance by facilitating use of fiber media instead of twisted pair As a sample calculation consider the question of what fiber cable distance connected by a pair of Magnum 14Es on each end can be obtained that will interconnect two 100Mb hubs where the twisted pair cables to the user nodes are 10 meters in length www GarrettCom com 37 Magnum 14E Media Converters Installation and User Guide 10 02
