For those of us who are more familiar with networking, especially our engineer friends, it's well known that twisted-pair cable has an “insurmountable” “100 meters” transmission distance. Whether it is 100M transmission rate of Category 5 twisted-pair cable, or 1000M transmission rate of Category 6 twisted-pair cable, the furthest effective transmission distance are 100 meters.

There are two main stacking connection methods: stacking card stacking and service port stacking. Stacking card stacking requires the purchase of dedicated stacking cards and stacking cables. Although this method is more expensive, it provides higher stability and transmission efficiency. Service port stacking, on the other hand, is more flexible, allowing users to use standard Ethernet cables or fiber optics for stacking. This method does not require additional hardware investment and is suitab
