We are regularly reading and experiencing the importance and advantages of a fiber network and the reasons behind the popularity it is gaining by each passing day. GEPON is also a part of this increasingly popular network architecture. Before getting on with GEPON, an introduction would do just fine, as where it came from. EPON (Ethernet Passive Optical Networks) or GEPON (Gigabit Ethernet Passive Optical Networks), also known as Ethernet PON is an IEEE/EFM standard for using Ethernet for packet data, as defined in IEEE 802.3ah. It defines how Ethernet can be transmitted over new media types and in our context point to multipoint fiber. EPON/GEPON is a fast Ethernet over passive optical networks which are point to multipoint fiber to the premises (FTTP)/fiber to the home (FTTH) architecture in which single optical fiber is used to serve multiple premises or users. A ‘PON’ architecture consists of an Optical Line Termination (OLT) on the provider’s side and one or many Optical Network Units (ONU) on the users’ side. This type of architecture is always better than the point to point ones. These are fast replacing existing technologies as DSL or cable modems as EPON/GEPON are capable of providing bandwidths of up to 1 gigabit and beyond and also serve multiple purposes at a time. GEPON or EPON has been deployed widely in Japan and provides for a symmetrical 1.0 Gbps data rate in both directions, upstream and downstream and is fast gaining momentum across the globe for obvious advantages for both providers and users alike. GEPON’s biggest advantage is its use of native Ethernet protocols. Also the economics of scale associated with Ethernet components such as optical interfaces, adds to it. GEPON or EPON provides seamless connectivity for any type of IP-based or other packetized (Ethernet) communications as it employs a single Layer 2 network that uses IP to carry data, voice, and video. Since Ethernet devices are present everywhere from home network to regional, national and worldwide backbone networks, implementation of EPONs has proved to be cost-effective. Also it provides secure communication as encryption is provided in both ends i.e. upstream and downstream, so the chances of eavesdropping fade away. As the transfer rates in Ethernet scale up by the day the scalability of EPON/GEPON is limitless and so is the flexibility of ADNET GEPON devices where we have a variety of products to choose from. Of the many advantages to offer some are worth to notice, With the GEPON/EPON standard, there is no limit on the number of ONUs, remember these are the units on the users’ side. At ADNET we have a range for these ONUs with varying features and competitive prices an example would be AN-ONU-FTTH-02 which are perfect for a building or an apartment setup to access the ip service, with fully integrated triple play solution to deliver TV, internet and phone services at the same platform. This is not the only one that is on offer, there is a wide range to select from depending on your requirement. GEPON/EPON requires a single management system, which means GEPON/EPON results in a significantly lower total cost of ownership. EPON also does not require multi-protocol conversions. Talking about management how can we forget the providers’ advantage using this technology? We have OLTs at the provider’s side, and for these too ADNET has a number of products to offer like AN-OLT-CC65000-4 which is perfect for the provider’s site which offers simplicity of Ethernet with effectiveness of bandwidth utilisation of fiber. It has built in routing/switching capabilities and can be integrated with the operator’s existing infrastructure. It also has triple play full integrated to deliver TV, Internet and phone services at the same platform. In the end, these are just a few advantages that this technology has to offer along with our product line. To really benefit from them you have to experience them and then you will come to know the real deal. Also do check the range of product on offer from us on our website.
