* Minimum cabling distance is 2 meters for -LR4 and -ER4 according to the IEEE 802.3 standard.
** Links longer than 30 km for the same link power budget are considered engineered links as per IEEE 802.3 Table 87–6. Depending upon link architecture, attenuation may be required to guarantee operation.
*** FEC in host is required to be turned on to increase the reliability of transmission.
