The MC1008 series Ethernet media converters are designed to extend the distance of your network by interconnecting LAN devices that are physically separated by large distances. These media converters have the functionality to connect any managed/unmanaged 1000 Mbps switch or hub using standard 1000T RJ-45 connections & convert the signal to 1000 Base optical via the SFP. The pluggable optics feature allows for flexible network configurations of reach whilst reducing the number of products for sparing & inventory. The AT-MC1008/SP media converter features a 1000T twisted pair port & an SFP port. The twisted pair port has an RJ45 connector & a maximum operating distance of 100 meters (328 feet). The fiber optic port has an SFP slot & a maximum operating distance dependent on the SFP. Although the provisioning of Gigabit Ethernet connections is becoming relatively inexpensive, thanks in part to the availability of lower-cost copper Gigabit network adapters, the distance limitations of copper cabling make fiber segments a necessity in most networks. Small, comparatively inexpensive copper to fiber Gigabit Ethernet media converters present a simple & very cost-effective way of connecting Gigabit Ethernet LANs over extended distances. Each small media converter is powered by an external power supply unit for use in standalone applications. Where multiple media converters are used, up to 12 standalone devices can be inserted into a low-cost AT-MCR12 rackmount chassis, allowing all the converters to be powered by a single internal power supply. In critical applications, a second load sharing internal power supply can be installed into the rackmount chassis.
