Performance of single-mode fiber links using electronic feed-forward and decision feedback equalizers

The performance limits of optically amplified links using electronic feed-forward equalizers and decision feedback equalizers are experimentally and numerically investigated. A 10-Gb/s transmission over 140 km of standard single-mode fiber with 22.7-dB optical signal-to-noise ratio sensitivity at 10/sup -9/ bit-error rate is demonstrated, allowing single-span operation with 4-dB margin.

Automated opto-electronic packaging for 10 Gb/s transponders

Integrated transponders are quickly displacing discrete module implementation in many 10 Gb/s line card designs. The emergence of the 10 Gigabit Ethernet (10 GbE) standard had placed higher demands on manufacturing scalability to meet the volume requirements of this application. To meet these challenges, we have developed a novel automated manufacturing implementation of small form factor, high performance, and highly integrated uncooled optics. We describe the design and automated manufacturing of such modules, present their performance, and show how they enable the implementation of new miniature, low cost 10 Gb/s transponders.

Automated opto-electronic packaging for 10 Gb/s applications

We demonstrate a new ceramic-based quasi-planar optoelectronic packaging technology specifically designed for high-speed performance and automated manufacturing. Its application to the development of miniature, low cost 10 Gb/s transponders is reviewed.
