Introduction Despite the slowdown in the communication industry, Internet traffic continues to grow rapidly, fueled by the explosion in data communications, mobile Internet, e-commerce, content rich applications, and multi-media services. Internet traffic has increased by approximately 80% yearly in each of the last three years, and will continue to grow at 60 - 80% annually … [Read more...]
Opto-electronic Transceiver Modules, a System Design Perspective
Introduction Small Form Factor (SFF) optical transceiver packages for use at 1-2 Gbits/s data rates have been described by several authors [1-5]. These rely on dual miniature optical connectors such as the MT-RJ or the LC to provide optical-component case widths as small as one centimeter. Passive alignment of the optical fibers with the active optical devices is achieved with … [Read more...]
