*Extreme Networks proprietary. Connections between two Extreme Networks 1000BASE-LX interfaces can
use a maximum distance of 10,000 Meters. However, it interoperates with standard 1000BASE-LX ports and supports a
maximum distance of 5,000 Meters.
Table 1-3 describes the specifications for the 1000BASE-LX70 interface.
*The transmitter output power level for the 1000BASE-LX70 is +5dBm. The maximum allowable receiver input power level is
-3dBm. Therefore, there is a minimum of 8dB loss required for the link to operate without errors. This minimum required loss
can be achieved using a fiber length of 32km (0.25dB/km provides 8dB loss), or by adding 10dB of fixed optical attenuator at
the receiver end.
