Media module MM992-2LH+, 2x 1000 Mbps SC, SM glass, max. 70 km

•SCALANCE X accessory, Media module MM992-2LH+, 2x 1000 Mbit/s SC-ports, optical; single-mode optical up to max. 70 km.
•Semi-modular and fully modular Layer 2 switches can be flexibly fitted with 2-port media modules.
•Using media modules enables: Extending the network by plugging additional media modules into unused media module slots at the switch at a later time Changing cabling technology, e.g. conversion from copper to fiber-optic cables or from multi-mode to single-mode FOC, bridging longer cable lengths or using existing 2-wire cables (variable distance).
•Unlimited flexibility during network expansions (e.g. more terminal devices) or conversion (e.g. switching from copper to fiber-optic cables) through modular construction using media modules.
•Reduction of storage and maintenance costs by focusing on only a few basic unit variants.
