Solutions for future mobile fronthaul and access-network convergence

Journal of Lightwave Technology, 2016
The trend in broadband access services is shifting from the fixed to the mobile. Accordingly, the role of the optical access network systems is changing from the fiber-to-the-home/fiber-to-the-building infrastructure to a common access platform that supports both the fixed and mobile broadband services.

Solutions for future mobile fronthaul access-network convergence

Optical Fiber Communication Conference, 2016
• Solutions for future mobile fronthaul □ In the short to mid term, how to carry CPRI/OBSAI/ORI is the key. The solutions include IQ-data compression, and fronthaul with WDM. □ In the mid to long term, a new function split is under study. It realizes a packet-based fronthaul, which allows the use of the cost-effective TDM PON technology. □ DSP-assisted

Bidirectional mobile fronthaul based on wavelength reused MDM

2016 15th International Conference on Optical Communications and Networks (ICOCN), 2016
In this paper, we propose a cost effective wavelength reused mode-division-multiplexing (MDM) system for high speed symmetrical bidirectional mobile fronthaul application. At the base band unit (BBU) pool, one of the spatial modes is used to transmit signal carrier while the others are used for downstream signal channels. At the remote radio unit (RRU)

Digital-Analog Mobile Fronthaul with Efficient SNR Scaling

Advanced Photonics Congress 2024
We overview the principle of hybrid digital-analog radio-over-fiber technique for high-fidelity and high spectral efficiency mobile fronthaul. The SNR scaling law is theoretically derived and compared with the existing radio-over-fiber techniques.
