Engineered For Performance
DMD Problem Solver
Offset launch technique on the transmit fiber eliminates differential mode delay (DMD) that causes bit errors when using 1000BASE-LX lasers with multimode fiber.
Legacy Fiber Investment Protection
Enables Gigabit Ethernet deployment over existing multimode fiber infrastructure, avoiding the cost of pulling new single mode fiber.
Dual Fiber Type Construction
Single mode transmit fiber is factory-spliced to multimode fiber with precise offset alignment, providing consistent performance cable after cable.
Typical Applications
1000BASE-LX over Multimode
Deploying Gigabit Ethernet using 1000BASE-LX transceivers over existing OM1/OM2 multimode fiber plants at distances up to 550m.
Network Upgrade Bridging
Temporary solution enabling gigabit speeds on legacy multimode fiber while planning a phased migration to single mode infrastructure.
