As I understand it, FDDI has a large installed base (but FDDI is "old hat"), and this bridging allows protocol mapping to ATM (and switched Ethernet?) In other words, old networks could connect via the GigaHub to new networks. Obviously of value to the customer as they can use some of the older installed base.
The fiber optic modules are needed literally all over the place! For example, I believe at this very moment I am communicating through several...In Seattle and San Fran something called "Ricochet" service (wireless 38.8 Internet service; ricochet.net ) is deployed via numerous tiny radio transceivers. However, at certain points data is likely picked up through some kind of fiber optic backbone. For each connection to fiber, a fiber optic module is needed. This same basic setup holds for ATM, ISDN, Gig Ether, CATV....in short, no matter who wins , fiber optic modules are needed a-plenty.
Why's fiber optic needed? It carries high bandwidth and is immune to electromagnetic interference, unlike wireless and copper. The kicker here is that as data networks become more and more complex, there is a greater need for fiber optic and fiber optic modules. The fiber cable is far easier to make than the modules; each module has a mini laser, as well as electronic circuits.
