Hitachi Unveils, MSA New, High-Integration, Compact 10Gbit/s Optic Transceiver -Delivers Terabit Optic Network Systems and Large-Scale IP Router Network Systems Compatible with Spiraling Data Traffic- |
Hitachi, Ltd.(TSE:6501) today announced its launch of a new 10 Gbit/s optic transceiver, Sample shipments will begin in September 2000 in Japan.. The new product is a compact, energy-efficient 10 G bit/s self-contained optic transceiver module that integrates multiple detached circuits optimized for the Internet age broad-bandwidth optic networks using DWDM (Dense Wavelength Division Multiplexing) systems and network configuration using IP routers. In March 2000 Hitachi concluded a multisourcing agreement (hereafter MSA) with Lucent Technologies and Alcatel Optronics for its 10 Gbit/s optic transceiver. The agreement mandates the development and merchandising of mutually compatible modules for use by all three parties. Hence, Hitachi's new transceiver is compatible with all three companies. Through the merchandising of this new product, Hitachi, Ltd. will contribute to the standardization of 10 Gbit/s optic transmission modules, demand for which is expected to grow rapidly. In 1995, Hitachi, Ltd. led the industry in developing and mass-producing 10 Gbit/s optic transmission modules and has held the lead ever since. To fulfill the needs for further high integration, compactness, and energy efficiency, the Company established direct modulation lasers and silicon germanium IC technology, with which it brought to market this new 10 Gbit/s optic transceiver. The product is a self-contained optic transceiver module based on the parameters stipulated in the MSA. Its optic transmissions are compatible with both 12km and 40km transmissions and comply with the international standards of the ITU (International Telecommunications Union), SONET (Synchronous Optical Network), OC-192, SR-1, and LR-2. A low-priced 2km and a long distance 80km version are also being planned for future release. The 300-pin-connected electric interface is compatible with Lucent Technologies' and Alcatel Optronics' products in terms of pin positioning, signal standards, and function. Moreover, the details of the electric interface are based on the OIF (Optical Internetworking Forum) standards. The new product integrates multiplex transmission circuits, clock generation ciruits, detached reception circuits, and optic transceiver circuits in a compact 89mm x 114mm x 18mm module case. To achieve this, a high-speed, low-power-consumption silicon germanium IC was utilized. Also, in the transmission section, a newly developed 1310nm direct modulation DFB (distributed feedback) laser module is employed for 12km transmissions, and a 1550nm laser module is employed for 40km transmissions. Hence, the product delivers compactness and low-power consumption and is perfectly suited for broad-bandwidth optic and IP router network development.
