For the 10GBASE-ER, you need to avoid the overload of the optical receiver when the
transmission distance is short: As long as the optical power at the reception end of the
fiber is greater than or equal to -1 dBm, you should add an appropriate optical attenuator
between the fiber at both ends of the link and the reception port of the 10GBASE-ER, so
Note
that the optical power at the reception end falls under -1 dBm.
