AFPON－N is the Ethernet communication terminal that is baseding
on passive light network ( PON )。The product takes " provides
overall communication method " as the design philosophy
，possess the characteristicthat the interface is diversified、the
group net is nimble and it is convenient to be managed。
The system is formed by OUT that is located transformer substation
side and IN that is located FTU side，The OUT can connection
many INs by way of the light go along separate routes 。Every
IN provides one road 10BASE-T's interface and two roads RS232's
interfaces for FTU ，among one road can be set up to the interface
of RS422 or RS485。OUT alse provides one road 10BASE-T's interface
and two roads RS232's interfaces。 |
|
| Function and characteristic： |
|
|
|
|
|
|
|
 |
Use the passive light network ( PON ) technology
of first-in |
|
|
|
Function of resisting loses the electricity
and closeing off malfunction，every IN that Electricity or inefficacy
are lost don't influence other communications of network |
|
|
|
The combinational network is nimble ，except
the star mould and the chain mould and self more encircling，support
the contact ring and mix the team net |
|
|
|
The low work loss design，IN's work loss is smaller
than 5W。 |
|
|
|
Not only support the Ethernet , and support
the various asynchronous serials to communicate by letter； |
|
|
|
Overall superfluous surplus backup merit ability |
|
|
|
Has the network management ability , and manage
each net unit of system completely by way of net pipe software

| The optical fiber distributes the net ODN： |
|
|
|
|
| |
ODN is major and forms by optical fiber and
the passive light go along separate routes wares，Being bare merit
rate and the light distribution of road , the light go along separate
routes wares can be laid up any place between bureau end and user
, and network architectures such as ring mould , star mould and
tree mould etc are constructed to the utilization light go along
separate routes wares with can making things convenient for .
|
|
|
|
|
| |
The major characteristic |
|
|
|
|
The group net is nimble , and the expansion
of node ability is strong |
|
The passive light parts capability is
reliable , and can suit the adverse circumstances |
|
|
|
It is low that the passive divides the
light network operating maintenance cost |
|
The optical fiber resources utilization
ratios are very high |
