FREMONT, Calif. -- NEC FiberOptech, Inc., a subsidiary of NEC USA, Inc., and WaveSplitter Technologies, Inc., a worldwide supplier of integrated optical components and modules for advanced optical networks, announced today the introduction of a wide range of new NEC transponder, transmitter and transceiver products which will be displayed at the Optical Fiber Communication (OFC) Conference in Anaheim. These exciting new products include: -- 10G MSA small-form factor (SFF) OC-192 transponders with lowest power consumption
-- 10G Multi-rate SFF transponders (SONET OC-192, 10 Gb/s Ethernet, and G.709 FEC rates)
-- Industry-compatible 16-channel and 4-channel 2.5G transponders
-- 2.5G DWDM transmitters supporting up to 480km
-- 1.25G Single fiber point to point bi-directional transceivers
-- 1.25G transceivers for Passive Optical Networks (PON) "NEC has differentiated its products while fitting within existing Multi Source Agreement (MSA) standards," said Mr. Yoshitaka Morimoto, President and CEO of NEC FiberOptech. "We have reduced the power consumption of the 10G small-form-factor transponders to be the lowest on the market and offer the highest data-rates available for PON transceivers. These new products also leverage the many years of NEC experience with active devices, delivering reliable products in high volume through the use of automated assembly." In a separate release: WaveSplitter Technologies, Inc., a worldwide supplier of integrated optical components and modules for advanced optical networks, announced today a joint development effort with NEC Corporation (Nasdaq: NIPNY; FTSE: 6701q.1; TSE: 6701) to produce dynamic gain flattening filters (DGFF), a key component to balance unequal amplifier gain in DWDM networks. The joint development product is based on a novel design manufactured using planar lightwave circuits, offering the promise of reliability and automated, low-cost manufacturing. This partnership combines NEC's system application design and electronic control circuit expertise with WaveSplitter's optical design and packaging capability to rapidly deliver an innovative product to market. "The dynamic gain flattening filter is a critical element for next-generation networks," said Keiichi Takahashi, General Manager, Fiber Optic Devices Division, NEC Corporation. "Partnering with WaveSplitter allowed us to design an innovative product that not only meet the network design criteria, but will also meet the reliability and volume cost requirements for the DGFF to penetrate the network." The dynamic gain flattening filter is used to optimize DWDM system performance by compensating for the uneven gain in optical amplifiers. The gain of optical amplifiers varies across the wavelength range, and this difference creates signal-to-noise problems in systems with cascaded amplifier chains, potentially limiting the distance a signal can travel without regeneration. Dynamic gain flattening filters compensate for this uneven gain even under varying network conditions, preserving the signal-to-noise performance and allowing transmission of signals over long distances with minimal regeneration.
