This talk examines the physical limitations imposed by basic topologies and
access couplers in fiber-optic interconnection of local area networks (LANs).
To that end, a detailed comparison of the basic topologies and node couplers
is provided.  The comparison is in terms of the amount of fiber required,
average propagation delay, fault tolerance, maintainability, number of node
couplers required, and maximum bit rate.  These results lead to simple guide-
lines for the choice of topology and the type of node couplers that may be
used in practical LAN interconnection.  Results indicate that for 100 node LAN
interconnection, the star topology requires 3.8 times as much fiber as a dual
ring, which may be of significant concern if the interconnection network is in
an urban business area.  The average propagation delay of a dual ring for a
100 node interconnection, on the other hand, is 3.33 times that of the star.
This may be a significant disadvantage in LAN interconnection networks where
the distance between nodes is large.  The maximum bit rate, by assuming simple
direct detection, is calculated for a fiber network based on the topology and
type of node coupler.  Our results show that the more fault tolerant a node
coupler is, the lower is the maximum bit rate it can support.
