I also had to work the 50 meter LC to lc multimode Duplex Patch Cable they bought for another site and have the logistics set up for that. I'm confident that I could get that to work if they had the right firmware but the one I sent them previously seem to have bounced the initial electronic mail address they gave me. The secondary one went through so we had the manageable switches updated then POOF! We have network and Internet connection working smoothly. I have not checked the status of that since I'm in a different department now, but I'm glad that worked in spite of using other brands in the network. I was afraid it would not be able to do it since the design on the GBIC connectors is proprietary with ours.
I wonder if I could take a peek at that case number I have in my notepad with the help of some of my peers who still are in that account. I fervently hope he did not have problems anymore because that was really a hard one to resolve. Lucky me they bought TCA Fiber Optic, CAT5 and CAT6 Network Cables. The mileage would definitely tell us what its worth.
