Description

The photoelectricity mixed ethernet switch of 48 ports can be provided

Technical field

The utility model relates to a kind of photoelectricity mixed ethernet switch, relates in particular to the circuit module of this switch.

Background technology

Communication industries such as the monitoring of industrial circle, control use the Ethernet mode in a large number, and communication terminal device mainly is the controller that has Ethernet interface or optical fiber interface, monitoring device etc.; Communication core equipment is Ethernet switch, and port generally is divided into optical fiber port and Ethernet interface, and communication media mainly is divided into optical fiber and Shielded Twisted Pair, and speed is in the majority with 100M (100 mbit/).

At present a large amount of Ethernet switches that use of industrial circle are mainly with full Ethernet interface, or a plurality of Ethernet interface to add 1～2 optical fiber port be main, speed is 100M.Under the more situation of user's field optical fibers terminal equipment, switch just can't provide more optical fiber interface and the interconnection of terminal optical fiber communication equipment.

And on some special import industrial measurement and control equipment, dispose the optical fiber interface of a kind of 10M, at present domestic still do not have the 10M fiber plant that can directly communicate with, so the 10M optical fiber communication equipment and its pairing that all need to buy external import are used.

In sum, in the communication of industry spot, the user just need a kind of can flexible configuration port number and type, and compatible extraordinary Industrial Ethernet switching equipment.

The utility model content

The utility model technical issues that need to address have provided a kind of photoelectricity mixed ethernet switch that 48 ports are provided, and are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: primary module; Described primary module comprises two exchange chips; Also comprise: 16 slots that are connected with primary module; Described each slot comprises 3 ports; Described 3 ports join with 100M optical fiber port module and 10M optical fiber port module or 3 ports and 10/100M network interface module are joined; Each slot in described 16 slots and optical fiber port module join or with the network interface module; Described 10/100M network interface module is joined by 100M network transformer and RJ45 interface; Described 100M optical fiber port module directly and the 100M optical fiber interface join; Described 10M optical fiber port module is by the transition of communications processor, join by 10M network transformer and 10M optical fiber interface again.

Compared with prior art, the beneficial effects of the utility model are: dispose very convenient, the user can free configuration switch port number and interface type, thereby make things convenient for industry spot user's communications network organizing widely, and can compatible import equipment, save time and the Financial cost of ordering import equipment for the user.

Description of drawings

Fig. 1 is a circuit module figure of the present utility model.

Embodiment

As seen from Figure 1: the utility model comprises: primary module; Described primary module comprises two exchange chips; Also comprise: 16 slots that are connected with primary module; Described each slot comprises 3 ports; Described 3 ports join with 100M optical fiber port module and 10M optical fiber port module or 3 ports and 10/100M network interface module are joined; Each slot in described 16 slots and optical fiber port module join or with the network interface module; Described 10/100M network interface module is joined by 100M network transformer and RJ45 interface; Described 100M optical fiber port module directly and the 100M optical fiber interface join; Described 10M optical fiber port module is by the transition of communications processor, join by 10M network transformer and 10M optical fiber interface again.

Primary module in the utility model, 10/100M network interface module, 100M optical fiber port module, 10M optical fiber port module, 100M network transformer, transition of communications processor and 10M network transformer all are modules of the prior art.

The utility model all docks with primary module by three kinds of modules, provides communication port by two exchange chips of primary module, to realize three kinds of communications between the module.Wherein 10/100M network interface module mainly act as butt joint user's 10/100M ethernet communication device; 100M optical fiber port module mainly act as butt joint user's 100M fiber optic communications devices; 10M optical fiber port module mainly act as the 10M fiber plant of butt joint import.

The utility model is made of a primary module and three kinds of business modules, and primary module can provide 16 slots for three kinds of business module butt joints, and three place's business modules all can provide 3 business interfaces, can connect 3 subscriber equipmenies.Wherein 10/100M network interface module is to be docked with the exchange chip of primary module by the network interface chip, docks with the RJ45 interface by the 100M network transformer, thereby for the user provides the RJ45 network interface of standard, realizes the networking of user network equipment; 100M optical fiber port module is to use the optical fiber interface chip to dock with the exchange chip of primary module, docks a kind of 100M optical fiber interface of standard at user side, can dock with user's 100M optical fiber interface, thus the networking of realization user's 100M fiber plant; 10M optical fiber port module is to be docked with the primary module exchange chip by the transition of communications processor, realize the conversion of 100M signal and 10M signal, and dock with the 10M optical fiber interface by the 10M network transformer, can be connected with user's import 10M optical fiber port equipment by the 10M optical fiber interface, thus the networking of realization import 10M optical fiber communication equipment.
