The distance between nodes depends on the transmission medium being used. MACRO supports transmission at the speed of light over glass fiber optic strands, as well as electrical transmission through RJ-45 twisted pair mediums. The chart below shows how the media affects the transmission distance.

Max DBN

Max TTD
|
|
Glass Fiber
|
3000 m (~ 10,000 ft)
|
768 km (~ 485 miles)
|
|
RJ-45 twisted pair
|
30 m (~ 100 ft)
|
7680 m (~ 5 miles
|
|
Max DBN = Maximum Distance between nodes
Max TTD = Maximum Total Transmission Distance (assuming a max of 256
nodes spaced a t Max DBN)
|
The signal is retransmitted to each station down the line on the MACRO ring. This allows the packets to be signal conditioned by each station that it passes through.
