Background technology
Ethernet cable extender is for transmitting ethernet signal by cables such as coaxial cable, telephone wire, a pair of twisted-pair feeders, its transmission range can exceed 100 meters, the longlyest reaches 2 kilometers.Due to its large cable transmission scope like this, in network transmission system, more and more used.This product comprises from end (being also far-end) and main side (being also center-side), often uses in pairs.Wherein far-end, for the signal being sended over by main side receiving is carried out to demodulation, is also transferred to main side after signal is modulated; Accordingly, main side, for the signal by sending from end receiving is carried out to demodulation, is also passed to from end after the signal of Ethernet switch output is modulated.Realize like this modulation of ethernet signal, thereby it can be transmitted on cable, the transmission range of expansion ethernet signal.
But, in prior art, because communication needs, can place a lot of main sides at convergence point place, then the RJ45 Ethernet interface of all main sides is connected to the switch at convergence point place, so need very many switch ports themselves.Those skilled in the art know, the ethernet switch port quantity of main flow is 24 at present, if this convergence point need to be connected from end with 100, so just need 100 main sides and 5 Ethernet switches, in addition, in prior art, the signal of this convergence point often needs by optical fiber teletransmission, to upper strata switching center, so also to need for each Ethernet switch arranges an Ethernet optical transmitter and receiver, as Fig. 1 at convergence point place.Visible, on this convergence point, just need a lot of main side, Ethernet switch and Ethernet optical transmitter and receiver, equipment is various.
Utility model content
Technical problem to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of new Ethernet cable extender main side, thereby reduce device data and the wiring at convergence point place.
The technical solution adopted in the utility model is as follows: comprise cabinet; In described cabinet, include multiple EoC modules, ethernet switching module and optical module;
Described each EoC module and ethernet switching module couple;
Described ethernet switching module and optical module couple;
On described cabinet, be provided with from end interface, light mouth and electricity mouthful; Wherein, described from end interface for by external cable with from hold be connected; Described light mouth is for being connected with upper strata switching center by external optical fiber; Described electricity mouthful is used for being connected with upper strata switching center or other ethernet device by external cable;
Described each EoC module is also coupled with respectively one from end interface; Described Ethernet switch also couples with described electricity mouthful; Described optical module also couples with described light mouth.
Preferably, described optical module is SFP optical module.
Preferably, comprise one or more light mouths; And described light mouth can be configured to 100M Ethernet SFP light mouth or 1000M Ethernet SFP light mouth.
Preferably, described electricity mouthful is 100MBaseT interface.
Preferably, described is coaxial cable, telephone wire or a pair of twisted-pair feeder from the external cable of end interface.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model in an equipment, and provides multiple from end interface by the Function Integration Mechanism of main side, Ethernet switch and Ethernet optical transmitter and receiver, effectively effectively reduces number of devices and the wiring at convergence point place.
The utility model can directly be connected with upper strata switching center by light mouth or electricity mouthful; Also can be connected with other ethernet device and realize expansion by electricity mouth, to meet this convergence point of access from holding more situation.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the connection diagram of existing Ethernet cable extender and Ethernet switch, Ethernet optical transmitter and receiver.
Fig. 2 is the structure principle chart of the utility model Ethernet cable extender main side.
