What is the wavelength allocation for video distribution in BPON access systems?

In BPON (Broadband Passive Optical Network) access systems, video distribution typically utilizes the wavelength range of 1550 to 1560 nm. This allocation is specifically designed to accommodate high-capacity video services while minimizing signal loss and supporting the delivery of high-quality video content.

The choice of this wavelength range allows for effective transmission over longer distances, as 1550 nm is known for its lower attenuation in optical fibers. This characteristic is crucial for video distribution because it enables service providers to deliver high-definition video content across extensive networks without the need for signal regeneration or additional amplification over intermediate distances.

Additionally, this wavelength allocation helps segregate video traffic from other types of data traffic, which can occupy different wavelength ranges within the optical spectrum. Such segregation ensures that video services can be delivered consistently and reliably, contributing to an overall better user experience for consumers relying on these services.
