Different wavelengths of light can use the same fiber without interfering with one another much like different channels on the radio spectrum can operate without interference. Inneos’ WaveStacker technology uses 6 different wavelengths of light to stack 4 data channels and a bi-directional backchannel onto a single fiber.
Other “pure” optical video solutions use multiple lasers, but they their lasers all use the same wavelength of light. This means the signals will interfere with one another if the signals were bounced onto a single fiber. Consequently, they require a bundle of fibers to transmit the same signal. This disadvantage of a bundle of fibers is that they can not be terminated in the field like a single fiber.
The telecom industry developed Coarse Wave Division Multiplexing to increase the distance of optical solutions by breaking high speed signals into lower speed channels which can travel further of fiber. Operating as Blaze Network Products, Inneos engineers first developed WaveStacker technology in the early 2000s for use in potential use data center applications. In 2003, the company was approached to help a customer move a high definition signal from NFL football fields to production vans in the parking lots of stadiums. For the last 15 years, the company has developed a variety of optical solutions specifically designed for video. The advent of 4K video and the optical revolution in AV has highlighted the usefulness of high speed video transfer over a single fiber.
