COST ASSUMPTIONS QQ <br />The following financial models are based on conservative estimates to reflect a "worst case <br />scenario" in which user take rates and revenue opportunities are low. It also does not consider <br />potential grant and assistance programs that may supplement the cost of the project nor lease <br />savings made possible by using City assets instead of leasing from outside providers. <br />The model assumes that Phase 1 will continue as is, but with a change in business model. <br />Currently, Lit San Leandro is only offering dark fiber services and is missing a large part of the <br />market. Dark fiber is not for all businesses as it requires a large capital expense in terms of <br />equipment, and resources that have knowledge and expertise in managing the appropriate <br />electronics to make the dark fiber useful. Dark fiber dedicates a strand of fiber for each end <br />user, that will in turn do what they want with that fiber. Eventually, many dark fiber suppliers <br />run out of strands to lease. An alternative approach is to offer "lit" services on a wholesale basis <br />to an ISP, that in turn offers services to the end user. Lit services, for purposes of this model, <br />will offer the following solutions: <br />• 1Gbps Dedicated (not oversubscribed, higher priced) $1,250 monthly ($720 wholesale) <br />• 100Mbps Dedicated $500 monthly ($360 wholesale) <br />• 1Gbps Best Effort (oversubscribed, less expensive) $130 monthly ($90 wholesale) <br />• 100Mbps Best Effort $100 monthly ($70 wholesale) <br />Offering these lit services opens the market from just large enterprise customers, to all small <br />medium and enterprise customers. <br />As of this writing, 1Gbps (1,000 Mbps) and 100 Mbps are products and speeds end users are <br />asking for today. However, it should be noted that the proposed network can deliver much <br />higher speeds than those advertised above, and consideration should be given to higher <br />offerings if it encourages a better take rate. Once the fiber is in the ground, the incremental <br />cost to provide 1Gbps service vs 100Mbps service is negligible. If offering a 500Mbps service <br />instead of a 100Mbps service will help in the marketing efforts, than it should be considered. <br />Dedicated vs Best Effort <br />Dedicated bandwidth essentially guarantees a certain level of performance between the <br />customer site and the internet connection point. Generally, no other users "share" the fiber, <br />but it is dedicated to that customer. <br />175 <br />
