Home » 10G PON: More Bandwidth for Sure, But There is More, Much More

After learning more about next generation PON standards, the benefits of each are clear. XGS-PON, with its fixed wavelengths, provides simplicity.

It is essentially GPON on steroids, providing common capabilities at higher bandwidths.

However, the additional wavelengths of NG-PON2 bring service providers some very unique operational capabilities such as:

10G PON Applications With these service provider benefits in mind, what are the subscriber applications driving 10G PON?

Residents of multi-dwelling units (MDUs) around the world are demanding higher bandwidth services and are not often receiving them. By delivering gigabit services to subscribers in an MDU, a GPON connection to that building can rapidly become oversubscribed. Therefore, 10G PON can clearly provide a benefit by delivering additional bandwidth to MDUs.

Beyond bandwidth, business services can take advantage of some of the additional benefits that NG-PON2 brings to the table. For instance, mission critical services at a medical clinic. A remote doctor consulting on a procedure would need high-quality video, as well as a highly reliable connection to that video to ensure the procedure is a success. In this case, the built-in redundancy of NG-PON2, which permits an ONU to transition to another wavelength or OLT if the service is lost, becomes critical.

Another application driving NG-PON2 would be 5G cell tower backhaul. Service providers are announcing their deployment plans for 5G, and given cellular data rates could be as high as 10 gigabits per second (Gbps) for 5G, bandwidth is critical. To backhaul traffic from the tower, connections faster than 10G are going to be required. This is where NG-PON2’s ability to deliver channel bonding will prove invaluable.

As the demand for bandwidth increases to a cell tower, it’s simply a matter of utilizing another wavelength over the existing fiber to the tower. Channel bonding enables the endpoint to see all the traffic (up to 80G using eight wavelengths) as a single stream of traffic. Channel bonding also means that if one of the wavelengths has an issue, traffic is still flowing to the end destination over the remaining wavelengths.

With XGS-PON and NG-PON2, service providers now have technology options that provide enough bandwidth for single-family units, MDUs, and businesses, enabling them to collapse all services onto a common infrastructure.
