Ceres
The device is intended for users with demand for packet traffic and classic voice connections. The device transports the stream of Ethernet frames and one E1 stream of 2048kbit / s through the optical path with the use of two single-mode or multi-mode fibers. It is also possible to transmit one fiber at a time using the WDM technique.
