Description
Technical Field
The present invention relates to the field of optical communications, and in particular, to an intelligent optical network terminal and an optical network system.
Background
A Passive Optical Network (GPON) refers to an Optical Distribution Network (ODN) between an OLT and an ONU, has no active electronic device, is a pure medium Network, avoids electromagnetic interference and lightning influence of external devices, reduces the failure rate of lines and external devices, improves the reliability of the system, and saves the maintenance cost. The passive optical Network mainly includes an olt (optical line terminal), an optical Network terminal onu (optical Network unit), and an optical splitter odn (optical distribution Network). At present, the passive optical network is mainly an IP-based GGPON, supports the highest asymmetric transmission rate of 2.488Gbit/s at the downstream and 1.244Gbit/s at the upstream, has the maximum physical distance of 20km, and supports the optical branching ratio between 16 and 128.
Poe (power over ethernet) refers to a technology that, without any modification to the existing ethernet cat.5 wiring infrastructure, can provide dc power for some IP-based terminals (such as IP phones, wireless lan access points AP, network cameras, etc.) while transmitting data for these devices.
A complete POE system comprises two parts, namely a Power Sourcing Equipment (PSE) and a Powered Device (PD). The PSE device is a device for supplying power to the ethernet client device, and is also a manager in the whole POE ethernet power supply process. The PD device is a PSE load receiving power supply, i.e. a client device of the POE system, such as many ethernet devices, e.g. an IP phone, a network security camera, an AP, a Personal Digital Assistant (PDA), or a mobile phone charger. At present, a POE system has two standards of 802.3f (POE) and 802.3t (POE +), and the output power of the two standards is not more than 30W, so that many high-power PD devices cannot be used;
the conventional optical network terminal needs a local power supply to supply power, and data information is lost once power is cut locally. In addition, the POE system of the prior optical network terminal adopts the 802.3af or 802.3at standard, and the output power of the PSE does not exceed 30W (the power received by the PD equipment is only 25.4W), so that the power of the powered equipment is larger than 25.4W and the powered equipment cannot be used;
the conventional optical network terminals are designed conventionally, have large volume and need to be placed on a desktop or other places, and adopt networking modes of an Ethernet switch, a network cable and an RJ45 panel on a wall, so that information needs to be transmitted among offices through electric signals, and the information is easy to steal.
