*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.
Table 1-3 describes the specifications for the 1000BASE-SX and 1000BASE-LX interfaces.

ULL UPLEX
The Alpine 3800 series switch provides full-duplex support for all ports. Full-duplex
allows frames to be transmitted and received simultaneously and, in effect, doubles the
bandwidth available on a link. All ports on the Alpine 3800 series switch autonegotiate
for half- or full-duplex operation. Gigabit Ethernet and 100BASE-FX ports operate in
full-duplex mode, only.
