For distance of 3000ft, we have to use UTP active transceiver baluns at both 2 ends. However, spool of Cat5 or cat6 come in with 1,000ft/spool. How do we connect those spools together to make 3,000ft?

You can connect the cabling spools using simple B Wire crimp connectors if you have access to the joints. You can purchase these which come with a sealant as well for protection. Once all connections are made, use electrical tape to secure the joints and connectors so they don't get damaged during installation.

I prefer soldering the connections as well to ensure you have a good electrical connection. You can cover the soldered ends using these B wire crimp connectors (you may have to widen the hole in the B connectors so the wires fit in). :wink:

Do you think "RJ45 8-PIN MODULAR INLINE COUPLER STRAIGHT-THRU" will be more appropriate? I find it in "Cablestogo"

we use the same butt splice connectors made by 3m, but we prefer putting all connections inside gasketed j-boxes. the seal tape looks like an easy solution but in practice it doesn't last and usually turns into a gooey, sticky mess..
