MAR 2 8 1989 <br />BOOK '76 DU 448 <br />Budget Amendment #068 - Fiber Optic Replacement of Twinaxial <br />Cables from Administration Building to Courthouse & Annex <br />The Board reviewed the following memo dated 3/22/89: <br />TO: The Honorable Board of DATE: March 22, 1989 FILE: <br />County Commissioners <br />THROUGH: Jeffrey K. Barton <br />Clerk of the Circuit <br />Court <br />SUBJECT: Fiber Optic Replacement <br />of Twinaxial Cable <br />FROM: Edwin M. Fry, Jr. REFERENCES: <br />Finance Director <br />I am requesting $28,336.00 to purchase a fiber optic cable to <br />replace the twinaxial cables that go from the IBM System 38 <br />in the administration building to the computer devices in the <br />courthouse and the courthouse annex. <br />Presently, we have ten twinaxial cables that go from the <br />administration building to the courthouse and the courthouse <br />annex. These cables are strung along on the power poles <br />between the two locations. The twinaxial cables have not been <br />as reliable as we would like. They are subject to lightning <br />strikes, power surges, the squirrels like to chew on them, and they <br />have an estimated useful life of seven years. Two cables were <br />installed eight years ago and two cables were installed six <br />years ago. Replacement of each cable will cost approximately <br />$4,000.00. We also need another cable installed to provide us <br />with the ability to add additional computer devices in the <br />courthouse and the courthouse annex; however, the City does not <br />want us to add another cable because of the weight of the <br />existing ten cables. <br />For the last two years, we have been searching for an alternative <br />communication link between the two sites. We talked to a number <br />of different vendors and finally came up with what is the best <br />solution at the lowest cost. HB Communications will install a <br />fiber optic cable between the administration building and the <br />courthouse for $28,336.00 <br />The advantages of the fiber optic cable are it is not subject to <br />lightning strikes or power surges, will not be chewed on by <br />rodents, and has an estimated useful life of twenty years. The <br />one cable will replace the existing ten cables and provide us <br />with the ability to add more computer devices in the courthouse <br />and the courthouse annex. <br />8 <br />
