What is the difference between GPON and PON?

GPON (Gigabit Passive Optical Networking) and EPON (Ethernet Passive Optical Networking) are variations of PON (Passive Optical Networking) technology, or Fiber to the Home (FTTH) networks being deployed by Internet Service Providers (ISPs).

What is the GPON standard?

984, commonly known as GPON (gigabit-capable passive optical network), is a standard for passive optical networks (PON) published by the ITU-T. It is commonly used to implement the outermost link to the customer (last kilometre or last mile) of fibre-to-the-premises (FTTP) services.

What is gem in GPON?

The GPON Encapsulation Method (GEM) frames are transmitted between the OLT and the ONU/ONT. The GEM port is the virtual connection used to identify the service traffic. Each GEM port beans one kind of service traffic. Each GEM port is identified by the port-ID uniquely. The ALLLOC_ID ranges from 0-4095.

Is GPON shared bandwidth?

For example, GPON allows 2,300 Mbits/sec (i.e. 2.5-Gbits/sec line rate x efficiency) of bandwidth to be shared by 64 customers, or about 35 Mbits/sec per customer.

Is GPON single mode or multimode?

singlemode fibers
Typically GPONs are built based on singlemode fibers and only this medium is allowed in the ITU-T recommendations and is supported by active GPON devices.

What is difference between GPON and FTTH?

GPON is a telecommunications access technology that uses fiber-optic cabling to reach the user. This fiber optic technology provides faster data transmission and reception through a single fiber, with a point-to-multipoint architecture, which allows home optical fiber (FTTH), or a building (FTTB).

What is GPON fibre?

GPON stands for Gigabit-Capable Passive Optical Network, which is a point-to-multipoint infrastructure. The signal is sent through a splitter that fans out the data and shares it between several end users. Pooling fibre bandwidth amongst your neighbours makes it more affordable, but it also has limitations.

How many times can you split GPON?

GPON offers maximum flexibility because its 2.5-Gbits/sec bandwidth can be split up to 64 times to keep costs down. If needed, GPON also can use lower split ratios (i.e. 32, 16) to deliver more bandwidth.
