Media module MM992-4LD, 4x 1000 Mbps SC, SM glass, max. 10 km

SCALANCE X accessory; Media module MM992-4LD; 4x 1000 Mbit/s SC-ports, optical; single-mode optical up to max. 10 km. ng from SFP plug-in transceiver (1000 Mbps) to SFP+ plug-in transceiver (10 Gbps).Unlimited flexibility during network expansions (e.g. more terminal devices), conversion (e.g. switching from copper to fiber-optic cables), or performance enhancement (e.g. from Gigabit to 10 Gigabit) through modular construction using media modules and SFP+ or SFP plug-in transceivers. Reduction of storage and maintenance costs by focusing on only a few basic unit variants
