Packet Engines claims they can > drive 22km of dark fiber with no additional equipment or repeaters Actually, the word is "demonstrates", not "claims". :-) At Networld+Interop we had a 12,000 ft spool of fiber with 6 pairs of fiber. The 6 12,000 ft lengths were patches to provide a total of 72,000 ft of fiber and portions of our booth were run through that entire length. Not only that, but the 5 connections between the 6 lengths were done with normal patch cables and SC connectors (which are more lossy than a fusion splice). I work for Packet Engines as SQA manager and that spool is now in our demo area about 50 ft. away and we're still running voice, video and data through it for our demo's. > Bill > > ------------------------------------------- > Bill St Arnaud > Director Network Projects > CANARIE > [email protected] > http://www.canarie.ca/bstarn [email protected] Packet Engines, Inc.
