Information technology continues to develop and expand to create the best solutions for growing companies. A PON, or Passive Optic Network, communicates information via optical cables. It can carry ATM, Ethernet, and Gigabyte traffic, but today, the most highly used form of PON is GPON technology.
What Is GPON?
GPON technology began in 1995 with the dawning of fiber optics and PON. After the development of the Asynchronous Transfer Mode (ATM), the broadband PON, or BPON, emerged. However, broadband wasn’t large enough to meet customers’ needs. Hence, GPON technology was born. Gigabyte passive optic networks typically deliver 2.488 Gbits/s on the downstream bandwidth and 155 Mbits/s going upstream. Currently, GPON is more popular globally than APON or EPON.
How It Works
GPONs have several components. It starts with the GPON OLT (optic line terminal), which connects to multiple GPON ONUs (optic network units.) The OLT and ONU are connected by an ODN (optical distribution network) for one group to use. The ODN consists of optical fibers and at least one optical splitter. Inside these parts is a reflective material that turns light signals into electrical ones at the end of the cables. It is entirely passive, so very little energy is used.
When information travels downstream the GPON, it will go to each ONU that has an ID to receive it. The OLT will deliver the same quality of information to each network unit. Meanwhile, signals traveling upstream go through a time division multiple access (TDMA,) which will stagger signals going up from the networks. The messages will separately go through the splitter and then to the OLT.
What GPON Offers
GPON technology supports the IT needs of businesses around the world that need the bandwidth to support vast communication signals. GPON allows groups to communicate at a distance of 60 kilometers, and still be in one secure network. Because of the passive nature of optic networks, a large system can still run at a low cost.
GPON started to be used by traditional telco providers. Nowadays, the technology has become more popular mainly because electronic components, like LASERs and Fiber Optics, are cheaper and better. GPON has found a niche inside the private broadband networks business. GPON can be used to backhaul traffic for Wi-Fi, 4G LTE, and 5G networks. Retirement communities, hotels, and even offices can leverage the power of GPON.
NG-PON2 is a successor of GPON technology. Developed in 2015, it allows a total throughput of 40 Gbits and a symmetric bandwidth of 10 Gbits, a great improvement from the lesser, unequal Gbit capacities of GPON. NG-PON2 fits well into an existing fiber optic structure simply by replacing the OTN and the ONUs. To see which is a better fit for your company, contact Axus Technologies!
