December 17, 2002--PANDATEL AG is releasing an 10/100/1000-Mbit/sec Ethernet media converter, which enables the connection of large corporate networks to broadband IP backbones, and the high-speed transmission of data over long distances.
The ET-CG converts electrical into optical signals and also serves as a 10/100/1000BaseT modem. Thus, it can be used with older Ethernet networks and future-generation systems. The media converter can support distances of up to 70 km by using GBIC or SFP modules on the line side. The device's in-built management functions enable integration into existing networks and remote configuration.
The converter receives the electrical data in 10/100 or 1000BaseT standards on the line side via an RJ-45 port, converts it, and then transmits it over the line using a laser. The converter recognizes and processes the various data rates (10/100 and 1000 Mbits/sec) using auto sensing. To transmit the converted optical signal on the line side, there is the option of either a fixed connection or models with a slot for a plug-in GBIC or SFP module. Depending on the strength of the optical signal required, different types of lasers can be used. A range of singlemode and multimode laser types are offered. This allows for different wavelengths and budgets, tailored to the individual customer requirements. A maximum transmission distance of 70 km can be achieved using a distributed-feedback power laser at 1,550 nm with singlemode transmission.
The ET-CG is available with or without management functions as a rack mount card in 3U format for installation in a 19" rack or in a single-slot housing.
"We've designed the ET-CG for companies that want to connect their copper networks to backbones, and for city carriers or Internet service providers that transmit large amounts of data over long distances," explains Marcus Mueller, marketing director at PANDATEL (Hamburg, Germany).
