Typical costs: 1  A cable modem costs $40-$90. For example, Circuit City, an online-only retailer, sells the standalone Motorola SURFboard SB5105 cable modem for $60. 2  Some cable modems are combination devices with routers, which create a wireless network. These devices cost $80-$200. The more expensive units allow for faster rates of transfer. Amazon, for example, sells the Motorola SURFboard SBG900 DOCSIS 2.0 cable modem and router combo for $120.
Vertical fiber cable cost is calculated as 98.4 feet at $0.35/fiber/meter for two fibers. In this scenario, the all-fiber system is more expensive than UTP, due to the high cost of 100Base-FX NICs and the high cost of the Cisco 4000 series equipment.ertical fiber cable cost is 98.4 feet at $0.50/fiber/meter for two fibers. Again, the costs used for the model represent a starting point. The scenario shows at list price, running fiber in the horizontal is more expensive than running UTP.
