TIA's Fiber Optics LAN Section's (FOLS) premises cost model was the topic of a pre-conference half-day seminar at the Fall BICSI Conference. Designed to help network designers compare the installed first costs of different architectures, the cost model is a fully-interactive tool that can be downloaded for free from FOLS’ Web site. More than 100 people, mostly network designers, attended the seminar, which was presented by FOLS Chair Andrew Oliviero of OFS Optics, FOLS Vice Chair Rodney Casteel of CommScope and Robert Reid of Panduit.
The speakers gave an overview of two standards-compliant fiber-based architectures, Centralized Cabling and Fiber-to-the-Telecom Enclosure, showed how these architectures compare to a traditional Hierarchical Star approach, discussed how to use the cost model, and presented case histories to show real-life examples of how the cost model can help users identify the best solution for their needs.
Rodney Casteel described the three architectures used in the model, explaining the pros and cons inherent in each. He emphasized that although fiber-based networks are not the solution for every network, they offer important alternatives for network designers to consider. He pointed out that while the FOLS cost model addresses only installed first costs, fiber-based networks typically show significant savings over copper networks when life cycle costs are considered.
Robert Reid, who supervised the programming of the model at Panduit, focused on the specifics of using the model. In the sample scenarios, the cost model uses aggregate pricing derived from the PEPPM Technology Bidding and Purchasing Program, an on-line for government and educational institutions in California and Pennsylvania with secondary listings for most other states.
“The opportunity to teach this seminar at the BICSI conference is excellent for FOLS, because this is our target audience for tools like the cost model” said Oliviero. “We learned a tremendous amount from the session attendees. In addition to the lively discussion that developed as part of the Q&As, we also collected valuable market data through a survey we distributed. We plan to use this data to help us build the next version of the model.”
