Table 131 (page 260) lists supported long-wave transceiver distances and maximum supported
distances under ideal operating conditions. Some long-wave optical transceivers can transmit up
to a distance of 100 km.

You can use EFMS to allocate more buffer credits to ports of an H-series switch to achieve increased distance up to the limit of the
SFP capability.
