Wide report EPON+LAN application plan

At present amount of user of net of Chinese cable television already was achieved more than 100000000, basically exist with one-way network form. Maintain administrative cost to reduce, answer increasingly intense competition, how to make full use of existing HFC base network will extend two-way transmission business (such as: Order programme of TV of broadband, number, video) , what already made trade of wide cable operation is current and two-way transformed main task.

EPON nods dotty network structure and wide cable network very similar, the broadcast mechanism with natural at the same time EPON makes its suit to bear the weight of very much video business. GWD puts forward EPON+EOC in the light of sth resembling a net of wide electrified wire netting two-way transform a solution.

EPON+EoC plan allocates net share and EPON+LAN means just the same in computer room of city land with certain boundaries and light. Fiber-optic the CATV inside the aether net that outputs to the ONU after corridor and corridor passes EOC corridor equipment to mix, perhaps set ONU and EOC facility be in in smooth node, through branch alloter join comes each corridor, transmit on original cable next in reaching each user home, equipment of repass EOC client side is divided into aether net and CATV signal, provide TV and data professional work for the client. EOC equipment EOC uses fundamental frequency to transmit, need not power source is safeguarded simple.

Plan characteristic:

◆ is reduced greatly build and maintain cost - make full use of original cable, need not cable of reticle of new laid aether, reduce earlier investment, suit not to facilitate very much the village of new wiring two-way transform.

The bandwidth ability EPON with tremendous ◆ has the bandwidth capacity of two-way 1G, can upgrade to 10G, make sure user business grows the demand to bandwidth adequately.

The aether net technology with mature ◆ , reduce deploy and maintenance cost, accord with prospective technology trend, protect installation cost

The network layer class with concise ◆ , implementation carries the business configuration of end and management to safeguard, reduce maintain cost

◆ system expansibility is strong - of bandwidth and user amount upgrade the implementation that can go to the lavatory through ONU of farther transfer to a lower level.

The network disposition with quick ◆ - the network structure of EPON and light of shape of wide report tree allocate network network structure natural be identical, can undertake network deploy neatly, look of enlarge of progressively implementation bandwidth and the network that retreat into copper solely develop a tendency.
