Sumitomo Electric Industries will begin volume shipments of its XFP and X2 10Gbit/s pluggable optical transceivers in spring 2004. The transceivers use SEI's high-performance, uncooled 1310nm DFB lasers in a compact TOSA to combine low cost and high performance. With an optimum thermal design of devices and circuitry, they also achieve low power consumption.

"We have been sampling units to strategic customers", said Kevin Green, Chief Operating Officer at ExceLight, SEI's North American sales and marketing unit.

"They rate our clean optical output waveform as being better than our competitors' devices.

The combination of low power and clean waveforms provide a cost-effective, high-performance solution for 10Gbit/s applications".

The X2 transceiver supports 10-Gigabit Ethernet standards and transmission at distances of up to 10km.

Using a four-lane 3.125Gbit/s XAUI parallel interface, the transceiver complies with the X2 multisource agreement (MSA).

The XFP transceiver provides multiprotocol support for 10-Gigabit Ethernet, 10-Gigabit Fibre Channel and Sonet/SDH to distances of up to 10km.

It has a serial electrical interface and is based on the XFP MSA.

SEI will expand the line throughout 2004 to offer pluggable transceivers to satisfy a wide range of application needs.
