FTTH: Design Your Network Architecture
The rapid expansion of Fiber-to-the-Home (FTTH) technology has revolutionized the way we experience internet connectivity, offering unparalleled speed, reliability, and performance. At the heart of this advanced infrastructure lies the HGU ONU (Home Gateway Unit Optical Network Unit), a pivotal device that serves as the gateway between the optical fiber network and the end user’s home environment.
No matter what type of broadband network you ultimately deploy, the first step for network operators is choosing an architecture for the physical infrastructure. There are many factors to consider, including cost of materials and labor, time to deploy, future adaptability, and the degree of fiber richness required to serve the needs of your community.
What is HGU ONU
As the terminal of PON network, HGU ONU is an all-in-one device that serves as both an ONU and a home gateway designed for single-family units. It connects to the OLT via a PON uplink interface and a PLC Splitter, converting the optical signals from the PON network into electrical signals at the user end.
Additionally, it includes built-in routing, Wi-Fi access, and Ethernet switching capabilities. This allows it to effectively manage and allocate home network traffic, providing end-users with reliable and efficient network access.
For FTTH scenarios, the integrated features of HGU ONU make setup and management much easier:
- Fewer devices: Users don’t need to buy and manage multiple devices like routers, switches, and Wi-Fi access points. One HGU ONU can handle all the network needs.
- Easy installation and setup: HGU ONU devices are compact and easy to install. The entire home network can be set up with just a few simple steps.
- Unified management: HGU ONU provides a single management interface, allowing users to manage the home network, including device connections, bandwidth allocation, and security settings, all from one platform.
FTTH Network Solutions: Let’s Get Started
The simplest way to begin designing a fiber-to-the-home network architecture is to consider where you’ll be building it. These four options are the most common types.
Medium & Large Cities: Home Run Network
A Home Run network offers the highest bandwidth capability and the easiest upgrade path for densely populated areas.
- Connects each subscriber with a dedicated fiber to the signal source at the central office.
- Offers a high level of flexibility and port efficiency.
- Requires large cross-connect cabinets with dedicated pads or pole spaces.
- This is the most expensive network to build.
Large Towns & Small Cities: Centralized Split Network
The most common U.S. architecture, a Centralized Split network is best for a concentrated area of homes and businesses.
- Connects each subscriber with a dedicated fiber to a local convergence cabinet.
- Lower-fiber-count feeder cables connect the cabinet to the central office.
- Easy to change split ratios and transport technologies.
- Requires large, centralized cabinets with dedicated pads or pole spaces.
- High-fiber-count cables exiting the cabinets can be costly due to the length of the distribution.
Small Towns & Villages: Distributed Split Network
A Distributed Split network provides a leaner fiber solution for the central housing and business district of small communities.
- Connects each subscriber with a fiber drop cable to the closest splitter terminal access point rather than a dedicated fiber to a central location, which can limit future flexibility.
- Reduces the number of fibers required.
- Provides flexible split ratios with combinations of 2, 4, and 8 splitters.
- Troubleshooting occurs at several split locations, not one interconnection point.
Wide-Open Spaces: Optical Tap Network
An Optical Tap network is the best option for sparsely populated areas with limited future growth.
- Connects each subscriber with a dedicated fiber to the splitter terminal using extremely low-fiber-count cables.
- Requires careful planning to ensure sufficient signal reaches the last subscriber in the sequence.
- Any disruption at the terminal impacts all downstream subscribers.
- Limited bandwidth flexibility for subscribers sharing a single optical line terminal.
