To me the problem is that the little clips are "standard". I would be very
surprised if a vendor will have enough courage to promote something more
effective. To alleviate your problem you could try using a lighter weight
transceiver cable. For us most transceivers are within 5 meters of the host.
For short runs you don't need these really big fat cables. I think several
vendors build these short lightweight transceiver cables ( yes even HP does).
