A special grounding terminator (N-Series) is used in some network communications. This device terminates a local area network (LAN) cable to ground, in order to prevent continuous reflections of old traffic across the LAN. Once the traffic is broadcast once, then it reaches its destination computer, while the rest of the signal is sent to the terminator at the end of the LAN cable to be dissipated to ground. Without a terminating resistor, the traffic would reflect back down the LAN cable and interfere with new communications.
Once it serves its purpose, a broadcast becomes interference on a LAN cable that can hinder network reception of new traffic. Without a terminating resistor, any broadcast interference would eventually saturate the network and force network communications to stop.
Resistive terminators for LANs usually must be employed on both ends of a LAN cable with the computers connected along points in the middle. While there must be a terminator on each end of some LANs, special grounding terminators may not need to be installed on both ends; rather, at least one will assist with mitigating electromagnetic interference.
Some LANs employ the use of terminators that prevent the reflection of old network broadcasts from interfering with new ones.
Grounding terminators are equipped with a bonding point intended to be connected on a pathway to ground. Grounding terminators are valued for use in environments where there is electromagnetic interference.
