The fixed network has played an important role in life. With the rapid development of telecommunication, POL (Passive Optical LAN) is releasing its huge potential with a great combination with IoT and has been applied in all kinds of aspects such as VR games, high ultra-high-definition video streaming, telemedicine, etc. Under this condition, F5G is put forward with to support more cloud services requiring high bandwidth and low latency.
Part I. What’s F5G?
F5G is the fifth generation of the fixed network. F5G aims to provide superhigh bandwidth, complete optical fiber devices, high reliability of services and bring in more new services. With F5G, more chances will come and the economy will be stimulated through a better application of optical fiber to all fields such as education, E-health, transportation, finance, smart home, etc.
Seldom do people know that actually there are F1G to F4G prior to F5G. The frame below shows their difference. F1G targeted telephone services at first and now F5G has been empowering in different services.
The key technology of F5G including 10G PON, WiFi 6, 200G/400G, OXC, OXC all-optical crossover networks, and NG OTN is expected to synergize to the maximum.
Features of F5G:
The features of F5G involve Full-Fiber Connection (FFC), Enhanced Fixed Broadband (eFBB), and Guaranteed Reliable Experience (GRE).
The fifth-generation fixed network is characterized by ultra-high bandwidth, integrated all-optical connections, and optimal service experience, which are reflected by newly introduced scenarios, services and applications
Full fiber connection (FFC)
With the better construction of optical infructures and advanced technology like WiFi, many services are allowed to reach everywhere. F5G will offer massive connections by extending the number of scenarios and fiber connected devices. Enterprise/home access or industrial security video applications are beneficial from powerful POL solutions, enjoying high-bandwidth and low-latency transmission channels and saving the overall FTTH/FTTO costs of deployment and maintenance.
Enhanced Fixed Broadband (EFBB)
Using more advanced technology, the network bandwidth capacity can be increased more than 10 times. It enables upstream and downstream symmetric broadband capacity, achieving Gigabit homes, 10Gigabit buildings, and T-class parks.
Using more advanced technology, network bandwidth capacity can be increased more than 10 times, can achieve upstream and downstream symmetric broadband capacity, can achieve gigabit homes, 10 gigabit buildings and T class parks.
Guaranteed Reliable Experience (GRE)
The guaranteed-quality F5G applications are of programmability, autonomy, low latency, interoperability, etc, which meets users’ requirements and improves the customer experience. For example, WiFi will be optimized to reduce the air interface latency, improve the reliability and interaction experience.
Part II. What’s the difference between 5G and F5G?
5G is the fifth generation of mobile telecommunication, which mainly serves for the access of mobile terminal devices like mobile phones. As for F5G, the fixed network telecommunication technology, serves for the optical bandwidth access of fixed networks through wiring. They are two different things but they share some technology and network.
Part III. Towards F5G: V-SOL WiFi 6 ONU HG325AX
Recently, V-SOL released a new xPON ONU with WiFi 6 router HG325AX, which signifies V-SOL’s first step towards to the F5G era.
The dual-band ONU router adopts Realtek Chipset WiFi 6 solution, reaching a maximum speed of up to 1800Mbps, which improves 52% in comparison to its last generation of WiFi 5 ONU. The OFDMA of WiFi 6 is conducive to reducing 75% latency. Each frame of the data structure of the WiFi 5 ONU can only serve one terminal device, but the WiFi 6 ONU is able to transmit data simultaneously to multiple terminals.
Moreover, WiFi 6 ‘s unified scheduling of hibernation and data transmission helps reduce 30% power consumption, which improves the lifetime of the ONU. The built-in signal amplifier FEM powerfully improves the penetration ability of the wall, making the signal cover more corners.
With the excellent WiFi 6 performance, the ONU can also be used in the WiFi Easymesh Solution. It can work as the main router, upward connecting to OLT. The terminal devices like the PC, mobile phone and IPTV can connect to the Internet through slave routers deployed around the house.
The XPON WiFi 6 ONU HG325AX is expected to improve as an F5G product with 10G PON. It’s believed that users can enjoy this in the near future.
Not only does F5G provide people provides ultra-high-speed broadband services with full fiber networks, but also it introduces more new opportunities to grow economically, revitalizes communities and helps build “Gigabit” communities. Additionally, F5G is beneficial to future-proof infrastructure and encourages migration and digital transformation. Let’s look forward to more production of outstanding F5G products.
