- Tx stands for transmission, and Rx stands for receiving.
- The R and T tags on BNC coaxial cables indicate the signal directions on a router. The R and T BNC coaxial cables must be connected to the Tx and Rx interfaces on the remote device.
Trunk Extension Cable
If the default length is not enough for cable connection, you can use a 75-ohm trunk extension cable as an extension cable.
When using a 75-ohm trunk extension cable to prolong a 75-ohm RJ45-to-BNC cable, connect one BNC connector of the trunk cable to a coaxial connector and the other BNC connector to the remote device, as shown in Figure 8-23.
Connection
A 75-ohm RJ45-to-BNC cable is connected as follows:
- The RJ45 connector is connected to a router.
- The BNC connectors at the other end are connected to a network device.
Ordering Information
If 75-ohm RJ45-to-BNC cables need to be prolonged, configure two RF coaxial connectors and two 75-ohm trunk extension cables for each 75-ohm RJ45-to-BNC cable.
Table 8-36 provides the 75-ohm RJ45-to-BNC cable ordering information.
