Fixed optical transport is the predominant fronthaul technology for 4G mobile access networks,
carrying the traffic between the central office and subtended antenna sites. With the new …

The increased carrier bandwidth and the number of antenna elements expected in 5G
networks require a redesign of the traditional IP-based backhaul and CPRI-based fronthaul …

With the development of 5G wireless network and beyond, the wireless carrier frequency
will definitely reach millimeter-wave (mm-wave) and even terahertz (THz). As one of the key …

We discuss the necessity of passive WDM technology in the 5G fronthaul application. The
proof-of-concept field trial showed that the proposed system integrated seamlessly with the …

The potential to operate third-party terminals over multi-domain transparent optical networks
attracts operators and customers to implement optical spectrum as a service (OSaaS). …

We report co-propagation experiments of the quantum channel (at 1310 nm) of a Quantum
Key Distribution (QKD) system with Dense Wavelength Division Multiplexing (DWDM) data …

In 5G networks, an optical fronthaul transports massive user data from remote radio heads (RRH)
to the core network (CO) with high throughput and low latency. eCPRI is a new …

We assess the performance of two distinct functional splits based on latency/latency
variation and mapping efficiency, both individually and in unison. By considering hardware-…

Mobile networks towards 5G impose increasingly stringent requirement on high throughput,
low packet jitter and low latency due to emerging time-sensitive applications. Ethernet-…

The common European Information and Communications Technology sector vision for 5G is
that it should leverage on the strengths of both optical and wireless technologies. In the 5G …
