Abstract
The utility model discloses an Ethernet optical communication device capable of performing subnetwork connection protection. Two EOS chips are adopted, the input end of each EOS chip is accessed to an optical module; a part of bidirectional dual-bus interface respectively accesses to the same communication bus; and the other parts of bidirectional dual-bus interfaces of the two EOS chips are in bidirectional communication connection with two Ethernet switches in a one-to-one correspondence mode. The Ethernet optical communication device is simple in structure and easy to implement, the Ethernet data transmission stability can be effectively improved, and error-free data transmission is realized.
Description
Technical field
The utility model relates to Ethernet optical communication apparatus field, but is specially a kind of Ethernet optical communication apparatus of dual transmitting and receiving.
Background technology
Ethernet is the most general communication protocol standard that current local area network (LAN) adopts, and it uses the CSMA/CD technology, and operates on polytype cable with very high transmission speed.In the prior art Ethernet data transmission course, normal because the fault of hardware causes data transmission fails, have influence on the normal transmission of data in the Ethernet.
The utility model content
But the utility model purpose provides a kind of Ethernet optical communication apparatus of dual transmitting and receiving, to solve the prior art Ethernet is prone to cause data transmission fails because of hardware fault problem.
In order to achieve the above object, the technical scheme that the utility model adopted is:
But a kind of Ethernet optical communication apparatus of dual transmitting and receiving; It is characterized in that: include two EOS chips; Each EOS chip has a plurality of two-way dual bus interface respectively; And the input of each EOS chip has access to optical module respectively; Said optical module is connected with external data source through optical fiber respectively, and two wherein a part of separately two-way dual bus interface of EOS chip insert same communication bus respectively, and two EOS chips also pass through the two-way dual bus interface of other parts and two corresponding one by one both-way communications connections of Ethernet switch separately respectively.
The utility model is simple in structure, is easy to realize, utilizes two EOS chips as the transfer of data chip; One of them is as the main chip of using, and another is as spare chip, and data get into main with behind the EOS chip from optical module like this; Transmit data through two-way dual bus interface to Ethernet switch; When optical module breaks down on leading with the EOS chip, can automatically switch to subsequent use EOS chip, proceed transfer of data.The utility model can effectively improve the Ethernet data transmission stability, realizes the fault-free transmission of data.
