2BASE-TL PHYs deliver a minimum of 2 Mbit/s over distances of up to 2.7 kilometres.

The minimum possible link bitrate for a single pair is 192 kbit/s, achieved by using 3 x 64 kbit/s.

The maximum bitrate for a single pair is 5.7 Mbit/s, reached by using 89 x 64 kbit/s.

On a 0.5 mm wire with 3 dB noise margin and no spectral limitations, the maximum bitrate can be achieved over distances of up to 1 kilometre.

At 6 kilometres, the maximum achievable bitrate is about 850 kbit/s.

The throughput of a 2BASE-TL link is lower than the link's bitrate by an average 5%, due to 64/65-octet encoding and PAF overhead.
