Tips:
When the public address distance is very long, it may be considered to use an Ethernet relay or to transmit via
optical fiber. If optical fiber transmission is selected, an Ethernet switch with optical fiber interface may be used,
or otherwise, a RJ45 to optical fiber port adapter may be used to convert electric signals into optical signals for
transmission. For details, please consult your network equipment supplier.
