| Chapter 9 GUIDELINES FOR FIBER Optic Design AND INSTALLATION eric PEARSON GENERAL GUIDELINES Use these guidelines for evaluating and comparing vendors choosing products and evaluating options and cost impacts of your decisions. 1. Start with a list of specifications. After the cable plant is designed but before you contact any manufacturers copy the information you have generated onto a specification summary sheet so you have all of the specifications for each component conveniently available when talking with potential suppliers. 2. All performance numbers need test specifications. In addition to learning whether the numbers are minimums maximums or typical performances you need to know how the numbers were determined. When comparing products from different vendors be certain that the specifications are the same so that you know that you are comparing apples to apples. 3. Talk to at least four vendors for each component. Remember that the fiber optic industry is highly competitive. You will be able to ask for and 115 116 CHAPTER 9 GUIDELINES FOR FIBER OPTIC DESIGN AND INSTALLATION usually receive the best price possible even though you may be comparing several products that are not identical such as cables or connectors. Remember to ask the question Why should I buy your product instead of another supplier s product The answer to this question may include mention of other suppliers or of equivalent products. 4. Talk with representatives more knowledgeable than yourself avoid the blind leading the blind. By this step in the process of designing your fiber optic system you should be more knowledgeable than many of the individuals selling fiber optic products. Therefore when you need information deal with people who know what they are talking about even if you have to bypass the salesmen or representatives and talk directly with the factory. 5. Expect and resolve conflicting facts opinions. At this step in the process of designing your fiber optic system you have .
