The "8-port fiber-optic switch" has been developed primarily for use in the patented "Mobile Server Mission System" together with the laptop Lizard RW11, but can also be easily used as a stand-alone or 19" version. The switch is based on the Cisco Small Business 300 Series and supports up to eight fiber-optic and one RJ45 port as well as Layer 2 and Layer 3 switching. The fiber-optic switch can be configured very versatile via the SFP modules. It enables full duplex, half duplex, symmetric and asymmetric transmission modes and allows VLAN, DHCP, port grouping and much more. The octuple Gigabit switch is simply coupled via retaining bolts to the RW11 or the RJ45 Switch and / or power module - vibration-proofed! The design according to MIL-STD810G, MIL-STD461F and the certification according to Tempest NATO 27 SDIP Level B (ER) (also in the system) allows almost no limits of use.
