450 Series MDAs

Four versions of gigabit Ethernet MDAs are available:

•Two shortwave gigabit MDAs (Figure C-1):

—The 450-1SR MDA is a single-MAC MDA with a separate redundant Phy (backup Phy port).

—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 (Figure C-2):

—The 450-1LR MDA is a single-MAC MDA with a separate redundant Phy (backup Phy port).

—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.
