This high-quality and robust switch has 12 SFP-ports and is thus highly suitable as a central switch for smaller and medium network. With 12 connections the switch enables the construction of one or more fault-tolerant optical-fibre rings. In case of an interruption the rings close automatically in less than 50ms, which improves the availability of the system. There are eight SFP slots for the backbone for 100/1000BaseSX/LX/ZX and four SFP slots for 1000BaseSX/LX/ZX which can be implemented for multimode or singlemode. The switches can also be used as single devices, for point-to-point connections or as connection modules. The extended possibilities of the management software enable the use of the switch in high demanding network systems. Easy top hat rail mounting. Normed plugs (RJ45 resp. LC) ensure all electrical and optical connections.
