Sumitomo Electric to Demonstrate New Range of 10G Transceivers

ExceLight Communications, a U.S.-based unit of Sumitomo Electric, is showing a 40-km XFP transceiver for SONET OC-192 IR-2 applications at this week's OFC in Los Angeles. A companion transceiver for 10GBASE-ER is also available. The XFP models can operate up to 70 degrees C using Sumitomo's temperature-controlled 1550-nm EML TOSA and PIN-TIA ROSA. They also feature a newly developed mini thermoelectric cooler (TEC), which requires only 60% of the power used by a conventional TEC. Sumitomo is already shipping samples of these 40-km products, as well as 10-km versions. http://www.excelight.com
