    MC has nine 18 series chips with a 10 base T ethernet controller built in, or you could use USB, RS232, or several other schemes for comms.

    i decided to use pic18f87j60 controller which has inbuilt ethernet module...please read the datasheet of pic18f87j60 page 207.here in block diagra there is pluse transformer for isolation instead fo this can we use opto coupler....

    While it may be theoretically possible to make a matching interface using optocouplers, I think it's going to be a tough route to pursue.

    Anyway, you'll need an RJ-45 connector, and there are RJ-45 connectors with built in transformers, like http://www.hirose.co.jp/cataloge_hp/e22229322.pdf
