The illustration at right shows a simple 2-node network similar to the one decribed before, except nearly all of the interconnecting UTP cable between the RAVE devices has been replaced by a pair of 100baseTX-to-100baseFX converters and a length of fiber optic cable. This conversion to a fiber optic medium allows the distance between the RAVE units to be increased to up to 2 kilometers.

More complex topologies with more than one fiber optic link are also possible, as shown below. Although any fiber link may be up to 2000 meters long, the maximum network diameter—the total span from one device to the furthest device—is also slightly more than 2000 meters, allowing for the delays inherent in the other cabling

and devices. In the system shown here, Fiber Link A and Fiber Link B can individually be up

to 2000 meters, but the total of their lengths should also be 2000 meters or less; For ex- ample, Fiber Link A could be 1500 meters, while B would be up to 500 meters; the UTP cabling length will also require adjustments

in the maximum lengths.

Likewise, the other network topologies described here earlier can be upgraded with optical fiber. This can be done with media conversion on individual network segments, as shown here, or by using fiber to interconnect hubs (illustrated on the following page), or combinations thereof.

*Although anyone fibersegmentcan beupto2000meters long, and

any single UTP segment can be up to 100 meters long, it may be necessarytoimposeshorter limits,inconsideration of cumulative delays caused by devices and cabling. See text for more information.

NETWORK LIMITATIONS

There are more possible combinations than can be shown in this or any book, and as long as they are compatible with 100baseTX Fast Ethernet standards, they will work with RAVE units. Keep in mind, though, that every hub, length of cabling, media converter, etc., delays the data passing through it by a small amount, and adding these to the system adds to the total delay time. CobraNet has a certain advantage over regular Fast Ethernet, however,
