3.18.1 Hybrid Wire/Fiber Networks
Figure 3.61 shows an electrooptic module used to replace a trouble-
some section of coaxial cable subject to noise, grounding problems,
lightning, or hazardous environments. When fiber is used in this mode,
the electrooptic module should be placed as close to the input/output
drop as possible in order to minimize the effect of potential electrical
noise problems over the section of coax cable connecting them.
