'BOCK 96 m�i 824 FIBER OPTIC CABLE - Utilization of fiber optic cable is the preferred method of connecting the towers, although funding could not be achieved since no revenue could be projected to offset the original quote of approximately $677,545 for a 24 strand cable infrastructure to connect the two east towers. A second estimate has been received which advises that the fiber optic cable cost will be $500,000. If the Board approves the 800 MHz contract, staff would not immediately file for microwave licenses and engineering in the early part of the contract period in order to further explore the potential revenue sources and cost of cable installation, given the recent reduced quote for fiber optic cable. This would be accomplished before determining the final tower connection method. Fiber optic cable it small strands of glass approximately 50 millionths of an inch thick. It is non-conductive and immune to lightning or other electrical interference. Its high communication capacity is demonstrated by the ability of one 48 strand cable to carry 650,000 'simultaneous. telephone conversations or 1,320 television stations at the same time. It is technology that provides a way of transmitting very large amounts of information at very high speeds for TV/video, computer data, graphics/pictures, remote control/alarm/data, and telephone/sound. The 800 MHz communications system would be a very small user of the fiber optic cable. For illustration purposes, each strand of fiber optic cable has the capability of 650,000 telephone circuits and the entire 800 MHz system would use only 96 of the 650,000 telephone circuits in one strand of a 24 strand cable. Aside from the cost related to the proposed contract, it should be noted that additional recurring costs could be.. anticipated as follows which would have to be funded at an estimated cost of $50,000 annually. ♦ Electrical power at three tower sites ♦ Two telephone lines for each tower site ♦ Six telephone lines.for the Jessica system between the tower sites ♦ Propane gas for tower sites ♦ Generator maintenance at West tower site ♦ Annual tower maintenance for West tower site ♦ Software upgrades starting the sixth year after acceptance of the system (not included in above estimate) ♦ Annual infrastructure maintenance starting one year after acceptance of the system (not included in above estimate) ♦ Annual insurance expense for tower sites ♦ Recurring expense of T-1 circuits to West tower During the negotiations, staff was unwavering in demanding certain enhancements and system features for the communications system. As a result of the negotiating team researching the existing contracts and utilizing information obtained from other counties' experiences during contract development, the following system features and technology are included in the contract with the cost being absorbed by Ericsson. COSTS SAVINGS NEGOTIATED IN FAVOR OF INDIAN RIVER COUNTY ♦ ProSound Software County $ 69,000 ♦ ProSound Software Cities 117,300 ♦ Infinity I - Rx Enhancements 325,000 ♦ 5 Years Software Services/Upgrades 325,000 ♦ Bi -Amp Systems 120,000 Total Savings $956,300 A considerable amount of time was spent on the APCO 25 Project which is a standard setting effort in the telecommunications industry to develop technical standards for the next generation of public safety radios, both voice and data, which will employ digital technologies rather than analog technology. Staff feels that the Ericsson "EDACS" System, which will be utilized by the County, remains at the forefront of technology. An example of this technology is "Prism," which currently meets or exceeds the functional objectives of the APCO 25 Statement of Requirements, Paragraph A, dated August 11, 1995. Provisions are included in the 54 December 19, 1995
