(2) Coaxial cable
The coaxial cable consists of an inner conductor and outer conductor. The outer conductor
functions as a shield. The impedance of the coaxial cable used for Ethernet connections is
50 Ω. Typical coaxial cables are the RG58A/U for 10BASE2 and the so-called yellow cable
for 10BASE5.
The maximum permissible cable length is 185 m for 10BASE2 or 500 m for 10BASE5.
When using a coaxial cable, be sure to establish a ground connection for noise control purposes
(provide Class D single-point grounding).

(3) Coaxial connector
The coaxial connector is commonly known as the N-type connector. It is used for connecting
a coaxial cable to a terminator or connector-type transceiver.
