Design of ONU in an EPON system
Gigabit Ethernet passive optical network (EPON) is an optical access network technology with a point to multipoint topology structure. It adopts Passive optical device to connect office end and remote end equipment, to achieve transparent transmission of Ethernet services, and to achieve access to integrated services such as voice and video in the same architecture. The outstanding advantages of EPON as an emerging access network technology lie in its low cost, easy maintenance, and good scalability. The EPON system consists of OLT, ODN (optical distribution network) and ONU. The hardware of the ONU system consists of two parts: a control module and a network switching module. The control module is the control and management core of ONU, providing a hardware platform for the operation of the operating system. Through it, the control and configuration of the network switching module are achieved, achieving the normal operation of the network switching module. The network switching module provides the function of exchanging and forwarding Ethernet frames. The control module communicates with the network switching module through PCI, visits the registers of each chip inside the network switching module, configures each chip, and retrieves the status information of each chip.
Advantages of an EPON ONU
Relying on EPON uplink, providing small and medium-sized multi-service access network methods. For example: ADSL2+, VDSL2+, POTS, LAN, etc ; Convenient and flexible networking applications; Easy and fast installation; High reliability and maintainability.
EPON application scenario – office buildings (FTTB)
The OLT is placed in the office computer room, and the high-rise can consider dividing the light inside the building. Other areas can consider dividing the light in the community. MDU equipment can be placed centrally or separately according to the height of the floor. The construction cost is lower than FTTH, but maintenance is not convenient.; For residential areas with broadband and narrowband needs (Scheme 1) or newly built buildings, built-in AG platforms or stacked IAD methods can be used to solve narrowband voice, while providing broadband access through MDUs. Need to consider IAD power supply issues; For office buildings, residential areas, or existing buildings that only require broadband, broadband access can be directly provided through MDU devices, and voice services can be provided through office equipment.
EPON application scenario – video surveillance
Video surveillance projects have a high demand for uplink bandwidth, a large number of terminals, wide distribution, wide EPON coverage distance, fiber saving, and high bandwidth, making them suitable technologies for achieving video surveillance ; Adopting EPON as the global eye bearer network also has the advantages of high reliability, anti-interference, and easy maintenance; ONU needs to have certain environmental adaptability to meet the requirements of outdoor applications.
EPON Application Scenario – Communication Network between villages
The purpose is characterized by dispersed access points, a small number of single point users, low demand for broadband, low ARPU value, complex environment, and generally no or poor computer room conditions; EPON’s tree based networking method fully adapts to the characteristics of rural terrain, effectively saves optical fibers, and terminals can provide GE or E1 interfaces, fully meeting the needs of rural wide and narrow bands. Combined with outdoor cabinets, it greatly reduces the cost of rural network construction; Passive networking has high reliability, low maintenance costs, and power outage nodes will not affect other nodes.
