<p>An apparatus (10) is provided for deployment in an outdoor environment for managing and distributing Ethernet-type data communication signals. The apparatus (10) includes electrical isolation elements (28, 29, 30 and 31) for various electromagnetic effects and a high speed pulse reshaper and repeater (12A-12D). The isolation elements (28-31) includes low capacitance electric pulse suppression devices (38, 40) so that maximum signal distance can be achieved without loss of usable pulse shape and isolation transformers (28-31) on differential signal pairs that retain magnetization at elevated temperature so that signals are not blocked. As a further feature, a management protocol is included whereby the type of signals can be autonomously distinguished, managed, secured and directed, thus allowing the apparatus (10) to be operated with compatible devices in daisy-chained and star switch fabric (14).</p> |
