The answer to this question depends on the transmission media which one chooses. 125MBit fiber optic transceiver circuits cost approx. $65.00 today. The RJ45 transceiver cost is significantly less at around $50. (Remember that multiple nodes may exist within a station, which can further reduce the overall cost.)
Costs on fiber optic transceivers and network interface devices have been to dropping as technology improves and competition in the communications industry drives down costs. It is not unrealistic to expect the cost per station on a fiber optic MACRO system to fall another 25% within the next year or so!
An important consideration which should be remembered is the savings in wiring costs, including labor time and troubleshooting time. These costs alone will exceed any additional cost that implementing MACRO hardware may induce.
