The linked document (which you trimmed) specifically says that an attenuator is required for an ER link <20km (underscoring your point), but doesn't mention that requirement for the OP's LR link. I guess you didn't find the link to information regarding minimum cable lengths, and attenuator requirement relevant to the discusstion? I hope that the OP, and the commenter running 1m LR links, and the commenter who suggested running short ER links without an attenuator find it useful. <shrug> /chris _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
