Description
Technical field
The present invention relates to the digital network transmission technology, be specifically related to the cable TV synthesized gateway.
Background technology
Current network is registered one's residence in the cable, and is the most general with twisted pair telephone, power line and CATV coaxial cable.And this becomes a kind of desirable broadband network access medium when standard coaxial cable is big by means of its bandwidth, shielding good, rate into family is high, service resources is abundant.But existing C ATV hfc plant is the One-to-All Broadcast formula, in today of technology and demand develop rapidly, along with professional continuous appearance and popularization such as Digital Television, digital speech, online game, IPTV, the user is climbed up and up to the demand of bandwidth, the network of One-to-All Broadcast formula can not adapt to the requirement of new business, to the transformation and upgrade of network with imperative.
At present domestic use MOCA technology insert the user of means as cable TV, all be that MOCA equipment is connected across in the cable TV network as a plug-in unit, the ONU of EPON part is arranged separately in the networking as a plug-in device simultaneously, couple together with equipment such as category-5 cable cable and MOCA again, construction is complicated like this, safeguards also inconvenient.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a cable TV comprehensive access gate that is applicable to the digital broadband user access network of CHINA RFTCOM Co Ltd system is provided on existing hfc plant basis, the high-performance of cable TV comprehensive access gate, low cost, easily installation, band webmaster, the good maintenance, the present situation that had both kept cable tv coax to register one's residence is again the basis of " integration of three networks ".
It adopts MoCA(MultiMedia over Coax Alliance) technical standard, under the prerequisite that does not influence existing CATV operate as normal, existing network is not done under the prerequisite of extensive change, modulation-demodulation technique with the advanced person, the signal of 800～1500MHz synthesized in coaxial cable transmit, be used to carry business such as IP-based data, voice and video with original CATV signal.
The technical scheme that realizes the object of the invention is: the cable TV synthesized gateway comprises the CATV Optical Receivers, ONU module, MoCA module, network management device and the power module that are provided with in shell and the shell; Wherein:
The CATV Optical Receivers is used to receive the light signal from front end, and bandwidth is 1GMHz, and output level is 105dBuv, and the automatic gain performance is-input of 5dBm-0dBm light that output voltage gradient is selectable 6dB or 8 dB or 10 dB;
The ONU module is used to connect front end OLT, finishes data communication, meets the IEEE802.3ah standard, and operating temperature range is wide, possesses 2 road or 4 road 100Mbps data-interfaces;
The MoCA module, the signal of the 100Mbps data signal modulation of ONU to coaxial online transmission, bandwidth 50MHz frequency is any one channel on the 860-1500MHz; Be single channel or 2 passages, each passage can be served 31 user sides;
Be provided with management devices, the management of CATV Optical Receivers and control device and the housing temperature checkout gear of management devices, MoCA or the HPNA of ONU or single fiber transceiver in the described network management device.
Described ONU module adopts modular organization, and is replaceable, when the user is unwilling to adopt the EPON mode to insert, can directly substitute the ONU module with single fiber ethernet optical fiber transceiver module.
Described MoCA module can be replaced with HPNA or PLC access module.
Described CATV Optical Receivers management and control device are used for luminous power detection, AGC control, output level control and slope control.
The present invention is based on EPON, the two-way net integral body of cable TV and last 100 meters accesses are unified to handle, the comprehensive arrangement inserted.Front end, primary transmission, distribution network with register one's residence at last under the management of united net management system, realize that quick for installation, with low cost, the convenient management of " comprehensive access gate ", maintenance are simple, register one's residence in the broadband.
The present invention is not changing under cable TV subscriber's cable connection situation, realizes inserting at a high speed up to 100Mbps.Make full use of the coaxial cable that cable TV is registered one's residence, not only reduced cost, laid good basis for " integration of three networks " simultaneously.
