- Application
- Adjacent racks, cabinet to server
The TP-Link SM5220-3M direct attach cable is the three-meter version: the length is enough to connect equipment in adjacent racks or route through a cable manager inside the cabinet. Carrying 10 Gbit/s without optical modules means fewer points of failure and a lower link cost.
Advantages
- Three meters reach adjacent racks and allow routing through a cable manager
- 10 Gbit/s without optical transceivers
- Fewer points of failure: no connectors to clean and mate
- Cheaper than a bundle of two modules and a patch cord
- A finished product — nothing is assembled on site
Applications
- Links between adjacent racks in a server room
- Connecting storage servers to the network core
- Stacking switches spread across a cabinet
- Video analytics and stream processing nodes
Frequently asked questions
How stiff is such a cable?
Stiffer than an ordinary patch cord, so the bend radius must be observed. It routes into a cable manager without trouble.
Are longer versions available?
Yes, the range includes different lengths. For distances of several meters and more, optics is the more common choice.
Does the switch need configuring?
The port usually detects the connection automatically. If needed, we set speed and mode during commissioning.
