Corning, JDS Uniphase and TriQuint Semiconductor are among exhibitors who introduced and announced plans for new products today at OFC/NFOEC 2005, being held this week in Anaheim.
   Corning Inc. launched it Polarcor Wideband, a solid glass polarizer for both the 1310- and 1550-nm wavelengths, a keystone component in polarization-dependent optical isolators. The polarizer compliments Corning's standard Polarcor and Polarcor UltraThin polarizing glass products. Corning's entire photonic portfolio, including polarizing glass, specialty fibers, GRIN lenses, lensed fibers, miniature collimators and other specialty materials, is on exhibit at booth 2201.
   JDS Uniphase (booth 1201) announced plans for 30 new product line extensions, including high-performance components for transmission and amplification applications, highly reliable datacom modules for storage and enterprise systems, components and modules for fiber-to-the-home, wavelength management modules for long haul, metro and enterprise networks and integrated optical subsystems for high-power amplification and cable television broadband networks.
   For the fiber-to-the-home and cable television markets, JDS Uniphase introduced the Series 4800 uncooled multimode pump module and the single- mode/multi-mode wavelength division multiplex (WDM) combiner for multimode erbium-doped amplifiers (EDFAs). The company is also previewing an expanded family of EDFA optical subsystems, including the 14-27 dBm EDFA PONA 2000 Series and 30-35 dBm EDFA PONA 3000 Series.
   JDS Uniphase's waveguide reconfigurable optical add/drop multiplexer (ROADM), already available in a C-band model, is now available in L-band for system developers building dense wavelength division multiplexing (DWDM) networks for telecommunications, CATV/MSO, and enterprise applications. The company said waveguide ROADM complements its wavelength blocker. It is also previewing future members of its wavelength management portfolio, including a multiport wavelength switch that provides colorless add/drop functionality for both 50 and 100 GHz, for both long-haul and metro markets, as well as new TOSA (transmission optical subassembly) products, including a 2.5-Gb/s uncooled Fabry-Perot 1310 nanometer TOSA, a multisource agreement (MSA) 2.5 Gb/s cooled 1550 nanometer TOSA with a directly modulated laser and a 10-Gb/s cooled 1550-nanometer TOSA with externally modulated laser (EML). New ROSAs include a 2.5-Gb/s avalanche photodiode (APD), 10-Gb/s positive-intrinsic-negative (PIN) and a 10-Gb/s APD. It will also preview 10 Gb/s X2 850 nm and 10 Gb/s X2 CX4 transceivers, along with RoHS-compliant 4 Gb/s models that provide multirate services.

   For the telecommunications market, JDS Uniphase is previewing a 2.5-Gb/s SFP DWDM, 10-Gb/s multirate SR1 XFP and 10-Gb/s DWDM full-band tunable transponder modules.
   TriQuint Semiconductor Inc. (booth 1463) introduced three low-cost ultrawideband (microwave monolithic integrated circuit) MMIC amplifiers (DC-40 GHz) and four packaged MMICs offering multiband performance, designed for the bandwidth needs of optical networks, point-to-point radio, military communications, instrumentation and homeland security applications.
