DCE/2178SMEE Super Mini Ethernet Extender


Data Connect 2178SMEE Super Mini Ethernet Extender is an excellent choice for Ethernet Extender applications where space and size are an issue. The DCE/2178SMEE offers new performance standards for the growing demand for high speed transmission of full bandwidth Ethernet and high-power PoE over extended distances on Twisted Pair or Coax. The 2178SMEE is designed to be integrated into existing products or to easily fit in standard 4 x 4 and J-Boxes, providing weatherproofing and compliance with fire and other environmental requirements. The symmetrical bandwidth assures full bandwidth transmission to be maintained over the entire operational distance for both uploads and downloads with virtually no packet loss.

The Data Connect 2178SMEE utilizes pass through PoE that eliminates the need for additional remote site power while allowing a single PoE source, such as a PoE network switch, to provide power to both transceivers and the camera. The 2178SMEE can pass through PoE power, up to 60W. Type tested under NEMA-TS2 environmental standards for extended temperature operation between -40°C to +75°C. The 2178SMEE is the perfect solution for extended distance data and power transmission for warehouses, parking lots, campuses, casinos, and many more.

The Data Connect 2178SMEE is Low Voltage and can easily fit inside most cameras housing and junction boxes. Best of all, it is type tested to network packet performance standards, and major camera brand compatibility tested to assure you error free and reliable. Installation cost savings, proven performance, and major camera brand compatibility all go into making the 2178SMEE’s the best choice for extended distance data and power transmission.
