10 Gb/s Ethernet Laser Communications Using Optical Space-Time Division Multiple Access

Free registration required

Executive Summary

The use of free-space laser communications for military applications will continue to increase because of its advantages with respect to bandwidth, low probability of detection, interception and jamming, and absence of spectrum restrictions. Multiple access, the ability of a terminal to simultaneously provide network access for multiple users, will become increasingly important as the number of users increases. Decreasing cost, size, weight, and power per user is essential to increasing the number and types of lasercom users. The authors have developed an approach to multiple-access lasercom that accomplishes this using the commercial paradigm of sharing the most expensive terminal resources among all the users.
