Description

A kind of ASON terminal and optical network system

Technical field

The utility model relates to optical communication field, particularly relates to a kind of ASON terminal and optical network system.

Background technology

EPON (Passive Optical Network, GPON), refer between OLT and ONU it is Optical Distribution Network (ODN), without any active electronic devices, be a kind of prefect dielectric network, avoid electromagnetic interference and the effects of lightning of external equipment, decrease the failure rate of circuit and external equipment, improve the reliability of system, save maintenance cost simultaneously.EPON mainly comprises OLT (Optical LineTerminal), Optical Network Terminal ONU (Optical Network Unit) and optical branching device ODN (OpticalDistribution Network).Current EPON is IP-based GGPON mainly, and it supports highest downlink 2.488Gbit/s, the asymmetric transmission rate of up 1.244Gbit/s, greatest physical distance 20km, supports that light is along separate routes than between 16-128.

PoE (Power over Ethernet) refer to when existing Ethernet Cat.5 connect up architecture without any changes, while for some IP-based terminals (as IP telephone machine, wireless local network connecting point AP, web camera etc.) transmission data, the technology of direct current supply can also be provided for this kind equipment.

A complete POE system comprises power supply unit (PSE, Power Sourcing Equipment) and power receiving equipment (PD, Powered Device) two parts.PSE device is the equipment of powering for ethernet client equipment, is also the manager in whole POE Power over Ethernet process simultaneously.And PD equipment is the PSE load accepting power supply, i.e. the client device of POE system, as IP phone, network security video camera, AP and many ethernet devices such as palmtop PC (PDA) or charger for mobile phone.Current POE system has two standard 802.3f (POE) and 802.3t (POE+), and the power output of these two standards is all not more than 30W, thus a lot of high-power PD equipment all can not use;

Optical Network Terminal in the past and need local power supply to power, local once have a power failure, data message just will be lost.In addition because the POE system of Optical Network Terminal in the past all adopts 802.3af or 802.3at standard, PSE power output is no more than 30W (power that PD equipment receives only has 25.4W), just can not use so power receiving equipment power is greater than 25.4W;

And Optical Network Terminal is in the past all adopt conventional design, volume ratio is comparatively large, needs to be placed on desktop or other place, adopts the networking mode of RJ45 panel on Ethernet switch, netting twine and wall, need by electric signal transmission information between office, such information is very easily stolen.
