Thus, the EPON and GPON protocols have different characteristics and, of course, each has its advantages and disadvantages. This is what you will see in the next item.
General characteristics of epon
EPON is short for Ethernet PON. Today, it is also call GEPON, because it is capable of delivering gigabit capacity; before, it was not like that.
Its fiber bandwidth capacity is 1.25Gb downstream (OLT-ONU) and 1.25Gb upstream (ONU-OLT), with a 28% overhead rate. It allows up to 64 clients per port. Some experts claim that it would be possible to increase this rate, but that this would increase the cost of the optical module substantially.
In general single-port devices
Available on the market, which is an advantage for those looking to buy a product with a lower capacity. The system is govern by IEEE standards, the body that regulates Ethernet networks.
Due to its characteristics, the management of an EPON network botim data is more limit and does not provide as much information about it. On the other hand, EPON interoperability — that is, the possibility of integrating products from different manufacturers — is high. An OLT can be made to work with most ONUs.
General features of gpon
Meanwhile, gpon is short for Gigabit PON; it is also known as G.984. The standard was creat in 2003 and has undergone several expansions and revisions. Compar to what came before, it is consider a completely new protocol, design to support multiple services in their native formats.
Its fiber bandwidth capacity is 2.5Gb downstream (OLT-ONU) and 1.25Gb upstream (ONU-OLT); it has an 8% overhead rate. It allows up to 128 clients per port. Often, only equipment options with eight or What are the differences more ports are available key attributes to remember for effective customer journey mapping on the market; only recently have equipment with four or more ports start to appear. The maximum distance that a network with the GPON protocol can whatsapp database brazil support is 20km, when there are 16 clients per port.
