DT-55

Is the performance of the beam affected by weather? As a general rule, Canobeam DT55 will perform well if the units are visible to one another, even in bad weather conditions. However, the effects of weather on optical beams should be considered. Rain, fog, and snow reduce, scatter light, and lessen the amount of light that passes between the units. Since this can result in errors, a backup line is recommended. The constant footprint and auto tracking functions give the Canobeam DT55 a strong advantage over other comparable products without these features.   Are the lasers safe? The Canobeam DT55 uses class 1B lasers. The laser light output by these units is safe even if viewed with the naked eye at the point of output for up to seven minutes. The use of magnifying optics is not recommended, as the effect to the eye through these devices will be stronger.   What happens if a bird flies across the path of the laser? If the laser beam is partly obstructed by a bird flying across its path, the amount of light passing between the units will be briefly reduced but there will still be adequate light for data transmission. If a bird obstructs the beam completely, the data will be momentarily interrupted but the problem will be resolved by a retransmission of the data since TCP/IP is used.   Is a relay setup possible? For network connections between buildings that are more than 1 kilometer apart, or that do not have a clear line of sight, pairs of CANOBEAM units can be connected to relay the signal. Because the waveform is normalized by the 3R function at each relay point, the data is not damaged by the relay process.
