There are a number of reasons why operators have favoured the use of GPON (Gigabit Passive Optical Network) technology within their networks and none more so than its fundamental architecture.
Unlike traditional networks which provide direct point-to-point links from customers to providers, GPON replaces the traditional copper ‘cat 5’ and network switching infrastructure and instead, uses passive splitters, allowing for a single fibre connection from the provider to multiple businesses.
Aside from the physical infrastructure that GPON technology offers the provider, it also has a far greater level of features than its rival EPON (Ethernet Passive Optical Network).
EPON (Ethernet passive optical networks) network technology doesn’t have the same level of features.
The level of security that GPON technology offers is a great attraction for operators.
Because GPON uses fibre, it creates a closed circuit meaning it cannot be hijacked or tapped. Not only that but encryption is also used to keep user’s data secure.
GPON can provide users with speeds of 100 Gb/s and beyond.
Some of the features of GPON are more sophisticated than other technologies, such as the ability to employ burst-mode (high-speed) transmission with statistical usage capabilities, allowing dynamic control and sharing of bandwidth, using committed and excess information rate parameters. This means that providers are able to offer users a minimum guaranteed bandwidth at peak times and superior service during less busy times.
Also, by connecting each user to an external communications room, it eliminates the need for mess or cables in an office, freeing up space and tightening security, plus bandwidth is not affected by the distance of the connection from the main comms room.
GPON’s splitter technology provides effective bandwidth management, preventing network congestion, which causes errors and retransmitting. This makes it particularly effective for video and voice, which require a stable network with minimal switches to work well.
Network providers are always looking for technologies that keep costs so the fact that GPON utilises a passive device, i.e. no active electronics are used on site, it eliminates the need for cooling or powering, vastly reducing operating costs and boosting stability.
Optical fibre is also unaffected by earth/ground loops, which can disrupt traditional networks and prove time-consuming and costly to eradicate. Neither is optical fibre affected by electromagnetic compatibility and radio frequency interference, which can disrupt traditional Ethernet networks, particularly at high speeds.
Because of its passive nature and ‘street cabinet deployment’ design, GPON saves thousands of pounds per site by eliminating the need for IT management support.
GPON speed is future proof to 1.6 Tb/s per fibre.
GPON technology has seen a huge rollout across Asia, particularly in China and its popularity continues to increase in the rest of the world. The benefits to both users and operators are plentiful and use of this equipment isn’t showing signs of decrease.
