25G PON Broadband Meets The Needs of Mobile Fronthaul
Nokia has recently conducted a trial in collaboration with Chunghwa Telecom Laboratories (CHT-TL) to validate the capability of 25G PON (Passive Optical Network) technology for small cell fronthaul in 5G networks.
In 5G deployments, transport networks are typically divided into fronthaul and backhaul segments to carry mobile traffic from small cell sites to the core network. While fiber broadband networks are already utilized for backhaul traffic, this trial marks an industry-first demonstration of how these networks, leveraging 25G PON technology, can effectively support the demanding requirements of fronthaul, including high capacity and low latency.
As operators transition to 5G, the higher frequencies used in the technology present challenges in terms of signal propagation. To ensure optimal capacity and coverage, operators need to deploy more antennas, and fronthaul transmission becomes crucial in connecting these new small cell antennas to the core network.
Fortunately, small cells and fiber broadband networks often have compatible footprints, enabling the use of existing fiber networks for 5G transport. The successful trial conducted by CHT-TL signifies that 25G PON broadband technology meets the specific needs of mobile fronthaul, offering a promising opportunity for substantial cost savings and improved total cost of ownership (TCO) by converging networks instead of building new and costly transport routes.
What is Fronthaul?
Small cell fronthaul refers to the transport of data and control signals between small cell base stations and centralized processing units or baseband units. Small cells are low-power, short-range wireless communication devices deployed in dense urban or indoor environments to enhance network capacity and coverage. Fronthaul, specifically, is the connection between the radio heads of small cells and the centralized processing units that handle the signal processing and management functions.
In small cell deployments, fronthaul ensures seamless connectivity and efficient operation. It enables the transmission of high-capacity data, voice, and video traffic between the small cells and the core network and achieves connectivity using various technologies, including fiber optic cables, Ethernet, or wireless links.
The purpose of small cell fronthaul is to offload traffic from the macro network and provide localized coverage and capacity. By deploying small cells, operators can improve network performance, alleviate congestion, and deliver better service quality in areas with high user density. At the same time, fronthaul connections help to ensure that the small cells are effectively integrated into the overall network infrastructure, enabling centralized management and coordination.
Although it has a number of advantages, small cell fronthaul also presents some challenges, including reliable and high-bandwidth connectivity, synchronization, and latency requirements. However, with advancements in technology and robust fronthaul solutions, operators can effectively address these challenges and unlock the full potential of small cell deployments.
Overall, small cell fronthaul enables efficient communication between small cell base stations and centralized processing units. It empowers operators to enhance network capacity, coverage, and performance, delivering improved connectivity and quality of service in densely populated areas.
What is 25G PON?
25 Gigabit Passive Optical Network – or 25G PON – is a broadband access technology that builds on traditional PON technology – such as GPON (Gigabit PON) and XG-PON (10-Gigabit PON) – and provides high-speed data transmission over fiber optic networks and offering even higher data rates than its predecessors. With 25G PON, the transmission of data can occur at speeds of up to 25 Gbps (Gigabits per second) in both the downstream (from the service provider to the user) and upstream (from the user to the service provider) directions.
25G PON is designed to meet the increasing demand for bandwidth-intensive applications, such as ultra-high-definition video streaming, cloud services, and Internet of Things (IoT) connectivity. It provides faster and more reliable connectivity, enabling service providers to deliver enhanced user experiences and support the growing data requirements of modern networks.
25G PON’s ability to support multiple services simultaneously, including high-speed internet, voice, and video, is highlighted by its capacity for improved latency, which is critical for real-time applications and services. Additionally, 25G PON is compatible with existing PON infrastructure, making it easier for service providers to upgrade their networks without significant investments in new infrastructure.
The deployment of 25G PON enables service providers to offer higher bandwidth, increased network capacity, and improved performance to meet the evolving needs of residential, business, and mobile users. In addition, it’s a future-proof solution that accommodates the ever-growing demand for faster and more reliable broadband connectivity.
