TriQuint unveils improved components for metro DWDM transmission

September 2, 2004 Breinigsville, PA -- TriQuint Semiconductor Inc. recently announced the availability of two new components designed to reduce the cost of line side metro DWDM transmission at both 2.5 Gbits/sec and 10 Gbits/sec. TriQuint's new components will debut at the European Conference & Exhibition on Optical Communication (ECOC) in Stockholm, Sweden, September 6-8, 2004.

September 2, 2004 Breinigsville, PA -- TriQuint Semiconductor Inc. recently announced the availability of two new components designed to reduce the cost of line side metro DWDM transmission at both 2.5 Gbits/sec and 10 Gbits/sec. TriQuint's new components will debut at the European Conference & Exhibition on Optical Communication (ECOC) in Stockholm, Sweden, September 6-8, 2004.

At 2.5 Gbits/sec, the new D2575 extends the reach and output power of TriQuint's directly modulated laser (DML) portfolio in a standard butterfly package. The D2575 offers a reach up to 200 km over standard fiber with a modulated output power of +7 dBm. This higher performance allows an economical DML solution to be used for spans up to 200 km and is a lower power consumption alternative to electro-absorption modulated lasers (EMLs), say TriQuint representatives. The D2575 is currently sampling in C-band wavelengths, with C-band production and L-band sampling scheduled for the first quarter of 2005.

At 10 Gbits/sec, TriQuint offers the new E4560 and E4561 EML products that feature more than 0.5-dBm output power for both 800-ps/nm (40-km, E4560) and 1600-ps/nm (80-km, E4561) reaches. In addition to SONET/SDH versions, the E4560 and E4561 are also now available for sampling across C-band wavelengths for DWDM applications, with production ramping through the first quarter of 2005. The E456x series is available in an industry-standard 7-pin half-butterfly configuration.

"TriQuint Optoelectronics continues to bring additional value to our customers by offering high performance components targeted for both line card and module applications," contends Erin Byrne, product marketing manager, TriQuint Optoelectronics. "The D2575 and E456x products will be offered at a minimal premium over their lower-performance counterparts."

Both the D2575 and E456x products are suitable for SDH/SONET or DWDM applications. The DWDM versions support wavelength stability of +/- 100-pm drift over life, consistent with 100-GHz spacing.Th 156853
