This may sound strange, but could I connect two DB528 over just
ONE pair of SMF?
Or will this trigger off some sort of alarm right away?
Note, there is nothing else on the FDDI ring, only the two bridges.

Yes. Think of it this way: connect the two bridges in the usual way, via two pair of fiber. You have a normal dual ring. Now disconnect one pair. You have a broken connection in the dual ring. The dual ring offers (single) fault tolerance: it wraps. So the single connection works. You have to connect A to B. Network management stations may give you a warning about this, because you have a wrapped ring, which is normally caused by a fault. But it is legal and will give you perfectly normal operation. It has no fault tolerance, obviously... To save a little money, you might use one 524 and one 526; that way you only pay for two single mode transceivers rather than four. paul | |||||
