Question

_________ is another kind of fiber optic network with an active star for switching.

(a) S/NET

(b) SW/NET

(c) NET/SW

(d) FS/NET

Answer 1

Correct choice is (a) S/NET

Easy explanation: A 50-MBd active star fiber optical Local area network (LAN) and its optical combiner and mixing rod splitter are presented. The limited power budget and relatively large tapping losses of light wave technology, which limit the use of fiber optics in tapped bus LAN topologies, are examined and proven tolerable in optical star topologies.
