What is the wavelength allocation for video distribution in broadband PON (BPON) access systems?

The correct choice reflects the specific wavelength allocation for video distribution purposes within broadband Passive Optical Network (BPON) access systems. In these systems, video distribution is crucial for delivering high-quality television services over fiber optics. The allocation in the range of 1,550 to 1,560 nm is particularly suitable for this purpose because it aligns with the transmission properties of optical fiber technology, minimizing signal attenuation and maximizing the distance over which signals can be reliably transmitted without the need for amplification.

This wavelength range is effective for both video and data services simultaneously due to its balance between bandwidth capacity and the ability to avoid interference with other services, such as voice and data, which may operate at different wavelengths. Thus, using this wavelength range ensures reliable delivery of video content, making it the preferred choice for BPON systems. It’s also compatible with the existing equipment and technology used in fiber optic networks, further supporting its selection as the correct allocation for video distribution.
