What is fronthaul in 5g

Sintai 5G WDM System offers semi-active WDM system and passive WDM system which is mainly used to solve the problem of lack of optical cable resources for optical fiber remote transmission between DU-AAU in C-RAN architecture, our fully self-developed system is the first to be launched in China, which has facilitated the rapid layout of 5G base stations at the remote and local ends.

SINTAI develops fronthaul in 5g WDM Sytem including:5G Fronthaul Semi-Active WDM Sytem, 5G Fronthaul Passive WDM Sytem.

5G Fronthaul Overview

Fronthaul is defined as the fiber-based connection in RAN infrastructure between the Baseband Unit (BBU) and Remote Radio Unit (RRU). Fronthaul originated with LTE networks when operators first moved their radios closer to the antennas. This new link was established to supplement to the backhaul connection between the BBU and central network core.
