thicknet is the colloquial name for which ethernet standard?
10base5
the first ethernet standard, known as 10base5 (thicknet) in the family of ieee 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10base2 (thinnet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market. the use of coaxial cable for ethernet is still supported by the standard, but rarely used because coaxial cable is more costly to purchase, install, and operate for local area networks.

the broadr-reach automotive ethernet standard realizes simultaneous transmit and receive (i.e., full-duplex) operations on a single-pair cable. in order to better de-correlate the signal, the digital signal processor (dsp) uses a highly optimized scrambler when compared to the scrambler used in 100base-tx. this provides a robust and efficient signaling scheme required by automotive applications. the broadr-reach automotive ethernet standard uses a signaling scheme with higher spectral efficiency than that of 100base-tx. this limits the signal bandwidth of automotive ethernet to 33.3 mhz, which is about half the bandwidth of 100base-tx. a lower signal bandwidth improves return loss, reduces crosstalk, and ensures that broadr-reach automotive ethernet standard passes the stringent automotive electromagnetic emission requirements.
