On average, Taara Lightbridge links will achieve annual availability of 95% at a range of 5 km and 90% at a range of 10 km. If you would like to see link performance from the field in various environments where we have deployed them, please contact your partner manager with your locations of interest.

Taara Lightbridge links perform similar to millimeter wave or E-band products in rain and snow, but experience significantly higher attenuation in fog. What’s important in the end from the perspective of the operator and end consumer is overall network availability: how often do these weather conditions happen, and when they do, whether there is efficient failover to backup systems across the network. Taara addresses the imperfect availability similar to multiband radio equipment, with failovers at different frequencies.

A single Taara Lightbridge link can transmit 20 Gbps bidirectional throughput over a minimum distance of 400 meters up to 20 km with line of sight. The effective range can be extended further when used as part of a relay system.

Taara Lightbridge links can be operated using +/- 48 V DC or PoE++ (UPoE). A Taara Lightbridge terminal at either end typically consumes 40 W of power (max 60 W), about as much as an incandescent light bulb. The source of the power can be solar, wind, or otherwise, as long as the continuously delivered power is of adequate wattage. We have used solar panels to power terminals deployed in remote locations or for disaster relief.

Taara Lightbridge links are currently manufactured and shipped from the U.S. or Thailand. Our contract manufacturer is responsible for global supply chain management, and final assembly, testing, packaging and shipping.

Yes; the Taara terminal hardware is designed for adaptive rate, and we are currently working to improve various dimensions of rate adaptation so that our system can trade throughput for additional availability.

What we learned from deploying Taara’s wireless optical links around the world over the last few years is that to make the benefits of high-speed internet accessible to more people, we need to reduce the complexity and cost of our technology so that it can become an affordable part of the global connectivity solution.

Our engineering team is currently focused on consolidating the functionality of Taara Lightbridge technology. The smaller, cheaper, more robust, and higher performance links would spur adoption of wireless optical communication closer to the edge of telecommunications networks.

Taara Lightbridge links are designed for a 7-year lifetime.
