This seems to suggest that error-limited performance is very roughly

bandwidth = (sqrt(mss) * C) / (rtt * sqrt(ber))

where the units are:
:mss = max segment size in bits
:C = dimensionless constant, approx 0.9 (see paper for more details)
:rtt = round trip time in seconds
:ber = bit error rate in per-bit

Note that this is a small-ber approximation, assuming loss is dominated by full-length packets.

Needless to say, the bandwidth does not go to infinity if the ber goes to zero: packet drops will occur when the b/w tries to exceed the physical link b/w.

This model appears to fit reality pretty well, according to the paper.
