SCALANCE X accessories, media module MM992-2LH+, 2x 1000 Mbit/s SC ports, optical, single-mode glass up to max. 70 km. SCALANCEMM992-2LH+ (SC)With the 2-port media modules, partially and fully modular Layer 2 switches can be flexibly equipped. The use of media modules enables: Expansion of networks by later plugging additional media modules into unused media module slots on the switch Change of cabling technology (e.g. switching from copper to fiber optic or from multimode to single-mode fiber optic), bridging longer cable lengths or using existing 2-wire cables (variable distance). Unlimited flexibility for network expansions (e.g. more end devices) or conversions (e.g. switching from copper to fiber optic) through modular design with media modules. Reduction of storage costs and maintenance effort by focusing on a few basic device variants.
