I ordered a pair of these, since they looked like generic CAB-OCTAL-ASYNC cables used by Cisco. They work great! They will work with a 2511 series router, or NM-16A/NM-32A line cards in any NM capable router. Also, the RJ-45 ends do have the snag-less boot pictured in the image. Quite a few generic CAB-OCTAL-ASYNC cables dont. Great deal, great price!
The octal cables fit well on both the HD68 and the RJ-45 ends. Cables were of the length I needed for my rack space. The cables are very durable, but flexible enough to be routed easily in the rack. Monoprice has become my go to place for cables because of the great quality, price and customer service.
PROS: The octal cables are well made and function as they should. The prices was great and I got more cable for the same price as shorter ones from other places. Shipping is very quick.
CONS: No cons really, to get a 10 rating they would have had to come with a lot of cable ties/wraps.
