WHAT IS GPON ?
GPON is one of the technologies developed by ITU-T via G.984 and until now competes with GEPON (Gigabit Ethernet PON), namely the IEEE PON version based on Ethernet technology. What is characteristic of this technology compared to other optical technologies such as SDH is the technique of traffic distribution carried out passively. From the central to the direction of the subscriber will be distributed using passive splitters
WORKING PRINCIPLES OF GPON
GPON is an FTTx technology that can send information to customers using optical cables. The working principle of GPON, when data or signals are sent from OLT, then there is a section called the splitter which functions to allow a single optical fiber to send to various ONUs, for the ONU itself will provide data and signals that the customer wants. In principle, PON is a point to multipoint system, which uses the splitter as a network divider
ADVANTAGE OF GPON
- Supports triple play applications (voice, data and video) on servicesFTTx is done through one fiber optic core.
- Can divide bandwidth up to 32 ONT.
- GPON reduces the use of many cables and equipment at headquarters if compared to point to point architecture. Only one optical port in the center office (replacing multiple ports).
- Bandwidth allocation can be set.
- Maintenance costs are cheap because they use passive components.
DISADVANTAGE OF GPON
- Complex layering model
- More expensive than GEPON
- Upstream bandwidth is limited to 622 Mbps
