450 Series MDAs

Four versions of gigabit Ethernet MDAs are available:
• Two shortwave gigabit MDAs
— The 450-1SR MDA is a single-MAC MDA with a separate redundant Phy
— The 450-1SX MDA is a single-Phy MDA.
These MDAs use shortwave 850 nm fiber optic connectors to connect devices
over multimode (550 meter) fiber optic cable.
• Two longwave gigabit MDAs
— The 450-1LR MDA is a single-MAC MDA with a separate redundant Phy
— The 450-1LX MDA is a single-Phy MDA.
These MDAs use longwave 1300 nm fiber optic connectors to connect
devices over single-mode (3 kilometer) or multimode (550 meters) fiber optic
cable.
