Hi! I am Shahed Israr. I try to help GPON Technology users with their queries and provide them with relevant and accurate information to the best of my ability. My main goal is to assist and enhance GPON Technology user and help people find the answers they're looking for quickly and easily.
GPON / GPON products / OLT / ONT
Gpon Equipment overview
Gpon Equipment overview: [boxads] Huawei OLT: OLT is one of the major gopn equipment. There are three types of frame. The large frame (SmartAX MA5600T) has 16 service slots while the middle frame (which named MA5603T) has 6 service slots and the small frame (which named MA5608T) has 2 service slots. The hardware and software are all compatible between MA5600T, MA5603T and MA5608T. Huawei PON SFP Module:
GPON Technology Diagram Overview
GPON Technology Diagram: Gigabit Passive Optical Network (GPON) is a high bandwidth shared fiber access technology. GPON is a point-to-multipoint access mechanism. Its main characteristic is the use of passive splitters in the fiber distribution network, enabling one single feeding fiber from the provider’s central office to serve multiple homes and small businesses. [boxads] GPON has a downstream capacity of 2.488 Gbps and upstream capacity of 1.244 Gbps that is shared among users. Encryption is used to keep each user’s data secured and private from other users. Although there are other technologies that could provide fiber to the home, passive …
PON Principles
PON Principles: [bodyads] (Almost) all PON types obey the same basic principles OLT and ONU consist of Layer 2 (Ethernet MAC, ATM adapter, etc.) optical transceiver using different ls for transmit and receive optionally: Wavelength Division Multiplexer Downstream transmission OLT broadcasts data downstream to all ONUs in ODN ONU captures data destined for its address, discards all other data encryption needed to ensure privacy
PON Types APON BPON GPON EPON WDM-PON
PON Types: A passive optical network (PON) is a system, that brings optical fiber cabling and signals all or most of the way to the end user. Depending on where the PON terminates, the system can be described as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB), or fiber-to-the-home (FTTH).[boxads] A PON consists of an Optical Line Termination (OLT) at the communication company’s office and a number of Optical Network Units (ONUs) near end users. Typically, up to 64 ONUs can be connected to an OLT PON port. The passive simply describes the fact that optical transmission has no power requirements or active electronic …
PON Architecture
PON Architecture: Like every other field, PON technology has its own terminology [bodyads] the CO head-end is called an OLT ONUs are the CPE devices (sometimes called ONTs in ITU) the entire fiber tree (incl. feeder, splitters, distribution fibers) is an ODN all trees emanating from the same OLT form an OAN downstream is from OLT to ONU (upstream is the opposite direction) PON Architecture Diagram: OLT (Optical line terminal) OLT is a terminal equipment connected to the fiber backbone. It sends Ethernet data to the ONU, initiates and controls the ranging process, and records the ranging information. OLT allocates …
