CHAPTER 2

INSTALLATION REQUIREMENTS

Before installing the FOT-F3 Fiber Optic Transceiver, all conditions, guidelines, specifications, and requirements included in this chapter and Appendix A must be met to ensure satisfactory performance from the FOT-F3. Failure to follow these guidelines may result in unsatisfactory network performance.

2.1NETWORK DESIGN GUIDELINES

The following design guidelines must be met when connecting devices using the FOT-F3.

2.1.1 Fiber Optic Requirements

•The fiber optic link segments should consist of single mode 8/125 - 12/125 ∝m fiber optic cabling. You can also use multimode 62.5/125 ∝m fiber optic cabling, but signal distance will be much shorter (about 2 km).

•The link segment must be tested with a fiber optic attenuation test set that is adjusted for a 1300 nm wavelength. This test verifies if the signal loss in a cable is within an acceptable level of 9.0 dB or less for any given single mode fiber optic link.
