Is WO-10 a HUB?
No, it is a physical media converter (electrical to optical and vice versa). Our equipment can be classified as passive transducers, which leave the transmitted data format intact.
What is the operating life of your systems?
The recommended operating life of our systems is 5 years. It is a matter of equipment obsolescence, first of all. Maximum lifetime depends on the LED emitters' lifespan, which is no less than 100,000 hours (11 years). As of the 1st of November 2001 the maximum operation life is 5 years. Warranty period is 1 year.
Your WO-10 models are designed for up to 250, 500 and 1,000-meter operational range. It determines the cost of solution. Which solution would be most cost-effective for the distance of 510-530 meters?
Recommended distances are determined with reference to the desired value of signal availability (no less than 99.7% of time per year).
These recommendations take into account the following factors: optics natural clogging, provided that lens cleaning is done once per year; seasonal variations of signal strength due to beam drift caused by building movement (provided that beam alignment rules have been followed); specific climate conditions in the arctic regions of Russia .
In your case an optimal solution should be determined by technical parameters dictated by the location and region you plan to install the equipment in.
The best solution is to consult with our engineers.
However, if you can sacrifice the decimal fraction of signal availability coefficient - it is not important for many tasks - you can make the choice yourself.
If you choose a 500-meter solution for your distances, you will lose 5-15% in signal strength.
Is it possible to install an access unit outdoors, next to the device?
It can be installed outdoors in an insulated thermobox, in case of extreme necessity.
Is laser communication secure enough?
No other wireless transmission technology is as safe as the infrared one. The only way to intercept the data is to place a receiver scanner within the narrow beam between transmitters. Since it is an extremely complex task to do, data interception is hardly possible. Infrared rays cannot be detected with scanners. Specific data transfer protocols provide additional privacy. Infrared systems have been used for a variety of applications that require high data transmission safety, including solutions for financial, medical and military organizations.
What happens if a bird flies through the laser beam?
If a bird (or any other object) should pass through the beam, neither equipment nor bird will be harmed. However, if the infrared beam is completely cut (by a large bird), the data transmission will be momentarily interrupted (for a split second). Depending on the protocol, system will either cache the data or report the error codes.
Can glass interrupt the beam?
Free space optical systems can transmit through glass, however, due to different absorption and reflection parameters of different glass types each case should be treated individually. In any event, transparent glass in the way of optical channel leads to a decreased equipment installation distance.
Are special permits or licenses required?
Because the systems use close to the visible infrared range of electromagnetic spectrum far beyond 400 GHz, the upper limit for radio frequency regulation in Russia , no licenses and special permits are required.
