michael. i don't have specific customer revenue percentages other than by market for 1997, but i know lucent represents roughly 20%. if you do the math on my 'industry' percentages below, the remaining 4% that i don't indicate (and usually cited as "other"), i believe is military. secure comm, radar, and the like. while this isn't the most current info, it along with the 10-k, doesn't cite ciena as a major. if you find anything more up to date, please post.
