They are reasonably fragile and it's easy to break lots of fibers.

Also, during final chassis / unit assembly, be careful about crunching these cables with tie-wrap guns. ______________________________ Reply Separator _________________________________ Subject: [TECHNET] Fiberoptic device handling Author: Steve Mikell <[log in to unmask]> at 0UTG0ING
