GPON is an evolution of GPON technology. There are also the stages of evolution are as follows:
1. ITU-T G.983
ITU-T G.983 is an ATM-based PON technology, supporting voice and data, efficiency of 70% f has a bandwidth of 622Mbps, adopted from ITU in 1999. Consists of Apon and BPON (ATM Passive Optical Network) is a standard PON (Passive Optical Network ) terutaman first used for business applications and using ATM technology. BPON (Broadband Passive Optical Network) is the development of Apon, this technology supports WDM and large upstream bandwidth allocation.
2. ITU-T G.984
ITU-T G.984 is a standard issued by the ITU-T GPON technology (Gigabit Passive Optical Network). GPON is an evolution of the BPON standard. This technology supports a great pace, the increase in security and a choice of 2-layer protocol (ATM, GEM, Ethernet). But in fact the ATM is not implemented. This technology has a bandwidth of 2.5 Gbps with 93% efficiency GEM (GPON Encapsulate Method) using frames segnmentation for QoS (Quality of Service) is greater. This technology allows several standard speed selection, but for the uniform industry 2.488 1.244 Mbps for downstream and upstream.
3. IEEE 802.3ah
IEEE 802.3ah is an IEEE standard for EPON issued or GEPON (Ethernet PON) is an Ethernet-based PON, IEEE / EFM on the use of Ethernet for data packets. This technology supports both voice and data, efficiency of 49%, 1Gbps bandwidth for upstream and downstream. This standard was made in 2004
4. IEEE 8022.3av
IEEE 8022.3av is a standard issued by the IEEE as the development of GEPON. This technology is commonly known as 10GEPON (10 Gigabit Ethernet PON). This 10GEPON using WDM technology standards.
2.4 Basic Principles of GPON [4]
Working principle of GPON is when the data or signals transmitted from the OLT, then there is a section called splitter that serves to enable a single optical fiber can be sent to a variety of ONT. For the ONT itself will provide the data - the data and the desired signal by the user. In principle, Passive Optical Network is a point-to-multipoint, fiber to the premise network architecture in which unpowered optical splitters (splitter fiber) single optical fiber. GPON system architecture based on TDM (Time Division Multiplexing) that supports T1, E1, and DS3. ONT has the ability to transmit data at three power modes. In mode 1, the ONT will transmit output power in the range of normal. In modes 2 and 3 ONT transmits a 3-6 dB lower than 1 mode which allows the OLT to ONT ordered reduced power when the OLT detects the signal from the ONT is too strong or otherwise, ONT OLT will give the command to increase power if the detected signal from the ONT too weak.
