In a discussion I had with a colleauge earlier today I recounted our earlier experiences with PONs going back to the mid-Eighties when we designed several trading floor applications around them. These were essentially passive "splitters" that were mainly 10-way networks comprised of fibers that had been annealed to each other (actually a tree of splitters within a single enclosure) allowing any port to talk with any other port. In one case we outfitted Goldman Sachs' then-provisional OTC desk and in several other situations we designed these passives into thousands of equity desks for Ethernet. Try picturing a hundreds of these all being brought back to a central closet: http://www.dbasinc.com/misc/config01.html During our 1989-1991 migration of several securities firms into the WTC we proposed using PONs for several high-density dealing applications but lost out to analog "video switches" (kludges of electromechanical relay-driven coaxial cabling farms), instead, but only because many of the market data services they needed to attach to were not yet re-engineered to support Ethernet. Most of these PON provisions came from a pioneering outfit working out of Yonkers, NY called Codenoll Corp. http://www.dbasinc.com/info/index.html , headed up by founder Mike Coden. Another outfit (with whom I think there was some OEM activity with the former) was Canadian company CanStar, a maker of optical splitters. A search of Codenoll earlier today revealed that the company had been acquired by DBAS systems back in 1999. I went to the site and found that some of the old literature from Codenoll was still being used, as evidenced by material relating to 386 and 486 platforms. Interestingly, the site shows one application that eerily resembles the kind of topology one might expect in a makeshift first-square-mile (FSM) or FTTx arrangement, using " CodeStar" couplers and active Ethernet switches: http://www.dbasinc.com/misc/config05ftth.html Frank Your comment concerning PONs moving into the enterprise caught my attention.
