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.
2.1 NETWORK 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
µ
m fiber optic cabling. You can also use
multimode 62.5/125
µ
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.
