Fujikura Europe introduces its new 4Gbps optical transceiver for the fibre channel and GbE markets from Sigma-links, the joint venture between its parent company Fujikura Ltd and OKI Electric Industry Co. Ltd. Totally backward compatible with slower speeds (1 and 2 Gbps) the 4Gbps transceiver can smartly adapt without the need for rate-select functionality. It is fully compliant with the new European legislation affecting the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS). Source: Light Reading
