Compact Optical Transceivers Have Low Power Dissipation Spec November 2001 Issue Published Date: November 01, 2001
New 2.5- and 10-Gb/s transceivers for the optical networking market are said to provide half the size and power consumption of previous models by using uncooled, directly-modulated lasers and high-speed integrated circuits. With the 4-channel 2.5-Gb/s and 16-channel 10-Gb/s transceivers, network system engineers can use a common design to shorten production time. The 2.5-Gb/s device measures 40.4 mm x 58.42 mm x 13.45 mm and is manufactured with high-speed CMOS LSI technology. The new 10-Gb/s device measures 63.5 mm x 89 mm x 13.5 mm and employs both high speed SiGe and CMOS LSI technologies. It operates at a typical power consumption of 6W, with a maximum of 7.5W. Both transceivers comply with electrical specifications set down in multiple source agreements and both also comply with global ITU, SONET and OIF standards. OPNEXT INC., Eatontown, NJ.
