Yes,
I agree with Jorge, Valy, Satish & Mr. Yao (SARFT), that a Bridge
makes more sense.
‘Media
Converter’ implies a PHY-layer hub, which will not be optimum for coax.
MACs
are just digital logic, which are fully exposed to Moore’s Law.
Why
preserve the MAC, if it becomes a vanishingly small part of the
solution?
Particularly
when preserving the sub-optimum MAC ruins the economics on coax.
‘Bridge’
is actually the more generic term.
The
advisable approach is to bridge to coax-optimized technology,
with
IEEE focusing on specifying the manageability & provisioning across
that bridge.
