The 450-1LR MDA is a single MAC MDA with a 
separate redundant Phy (backup Phy port). Only one 
Phy port can be active at any time. If the active Phy 
port fails, the redundant Phy port automatically 
becomes the active port.

•

The 450-1LX MDA is a single Phy MDA.

Both models conform to the IEEE 802.3z 1000BASE-LX 
standard and use longwave 1300 nm fiber optic connectors 
to connect devices over single mode
(3 kilometer) or multimode (550 meters) fiber optic cable.

Table 6 describes the 1000BASE-LX MDA components 
and LEDs.

For installation instructions, see “Installing an MDA” on 
page 22.

Note: 

The optical performance of this transceiver 

cannot be guaranteed when connected to a multimode 
fiber plant without the use of the special offset 
SMF/MMF mode conditioning patch cord (see 
“1000BASE-LX Multimode Applications” on 
page 25).
