The following WLAN components are commonly used:
Splitter: divides a signal into two or more signals.
Coupler: divides a signal on a port into uneven signals on multiple output port.
Attenuator/Load: reduces the amplitude or power of a signal without appreciably distorting its waveform. The load is a special attenuator with unlimited attenuation. The load connects to the unused output radio port, preventing radio interference.
Combiner: combines radio signals of multiple systems over one channel and distributes receive signals over one channel to ports of each system without interference. Combiners are classified into single-band combiners and multiple-channel combiners.
Type N connector
Surge protection device
Other protection components: optical fiber tube, ground cable, and waterproof tape
