I would like to make a run of cat 6 ethernet cable between 2 dwellings, underground. It appears I may need just a little over the maximum length for 1 Gbps (100 meters), maybe 110 meters or so. Putting a switch in between is impractical. And actually for the application, 200 to 300 Mbps should be ample. POE is not required.
Is there a formula or graph available which describes the degradation over length, eg maximum speed vs length?
Cat 6 is rated 50 meters for 10 Gbps and 100 meters for 1 Gbps. Perhaps it is something like, for every doubling of cable length, speed is reduced by a factor of 10?
As I already have the cable for the job I'd rather not add the expense of going with fiber.
