Nokia Bell Labs has announced the first successful demonstration of ultra-low latency 10G passive optical networks (PON) for mobile fronthaul.

In the demonstration, Nokia Bell Labs showed how it is possible to use a commercial next-generation PON to transport ultra-low latency CPRI streams via a standard single fiber running between the Baseband Unit (BBU) and the Remote Radio Head (RRH).

The proof-of-concept demonstration indicates how existing fiber networks can be used to cost-effectively transport mobile traffic, which could accelerate the transition to 5G.

The trial used XGS-PON technology that runs on existing fiber access networks and allows operators to use GPON platforms to deliver high-capacity services.

“This is an important milestone in the industry and in the advancement of 5G, showing for the first time how a PON network can effectively be used to support very high capacity, low latency applications,” Nokia Bell Labs head of access research Peter Vetter said.

“It demonstrates the flexibility of PON to support traditional CPRI and evolving mobile specifications, such as fronthaul over simpler native Ethernets, and validates the readiness of PON for the 5G era."
