JANUARY/FEBRUARY 2014 | www.broadbandcommunities.com | BROADBAND COMMUNITIES | 47b localities may face from pole owners in attempting to enforce them – but we can afrm from experience that the technical benefts of such policies would be signifcant. 6 For example, Smyrna, Ga., requires users of its rights-of-way to share access to their poles, conduit, and related facilities. Smyrna, Ga., Code of Ordinances § 90-45. Superior, WI reserves the right to require joint use of poles or conduit. Superior, Wis., Code of Ordinances § 2-165(b). See Fiber to the Home Council Americas, www.ftthcouncil. org/p/cm/ld/fd=47&tid=79&sid=1249. 7 Tis is because there is currently a diversity of service approaches (e.g., non-fber technologies to the unit) and installing fber to every unit in a particular manner may lead to a signifcant stranded investment if no fber provider serves the building or if the service provider insists on using another type of cabling to the unit. 8 "Te Loma Linda Connected Community Standard," www.lomalinda-ca.gov/ asp/Site/LLCCP/AboutLLCCP/ TeLLCCPStandard/index.asp 9 City Council Member Jeremy Pietzold notes that his only regret about the new conduit ordinance is that Sandy did not have the forethought to pass it 10 years ago – which would have better positioned the city and its private partner to build the FTTP network they currently plan. (CTC interview with Council Member Jeremy Pietzold, February, 2013.) 10 Tis hypothetical is based on our own experience and data at CTC. 11 Our hypothetical assumes the following: the network is built to all or almost all of the 250,000 homes and businesses in the community. Approximately 3,300 miles of cable need to be built. Half of the cable is built aerially on utility poles and half underground, in conduit. A total of 300 miles of the cable construction is backbone cable, interconnecting approximately 40 hub facilities. Tere is a central network operations center and headend facility. Each of the hubs is connected over dedicated fber optic cable strand to approximately 6,000 homes. Te hubs house active Ethernet electronics and are located in facilities with backup generators and diverse connectivity to the network backbone. Te hubs require 300 square feet for fber terminations and electronics, plus HVAC. Te cost to build a hub facility is $100,000. Tere are approximately 35 poles per mile of aerial cable plant. Poles are on average 20 years old and there are cable and telephone incumbents on the poles. Make-ready cost (both make-ready and engineering) is $500 per pole on average. Aerial construction in this scenario is $25,000 per mile for attachment of new strand and overlash to strand; with make-ready included, the total average cost per mile of aerial outside plant construction is $42,600. Underground construction is primarily done through directional boring, with hand digging where necessary in sensitive areas, such as in the vicinity of other utilities. Where it is the most cost-efective approach for reaching premises, underground construction is done on both sides of the street; otherwise it is on one side with boring across streets. Te average cost of underground outside-plant construction is $100,000 per mile. If a street is cut, typically as part of a test pit for directional boring, the entire street is repaved 10 feet from the pit. Tere are 500 multi-dwelling-unit and multi-tenant ofce buildings in this scenario, with 50,000 residences and businesses in the buildings. Te average cost of installing services to individual units is $500, assuming the installation of services to the majority of units in the buildings. Te average cost of connecting a building to the cable plant in the rights-of-way is $5,000. Half the utility poles are owned by the investor-owned power utility and half by the incumbent telephone company. 12 In the event that fber count is insufcient to meet the needs of both the locality and the private partner who seeks use of the locality's fber, the existing fber can be cost- efectively augmented through electronics (such as DWDM) or through placement of additional fber (either in existing conduit or overlash of aerial plant). All of these strategies are signifcantly less costly than placing new fber without the benefts of existing conduit or aerial fber. 13 Inclusive of cable plant inside multi- dwelling-unit residences and multitenant ofce buildings. Localities can require developers to accommodate next-generation broadband in their building plans. Installing fber is much less expensive in a building that was designed for it from the outset.
