PURPOSE: To connect the interfaces of an optical fiber transmission line and a transmission line drive circuit to each other by a simple, low-price circuit. CONSTITUTION: This device is provided with TTL level converting circuits 7 and 8 which converts the levels of input and output signals of an IC 1 for the transmission line drive circuit of the IEEE802.310 base standards. This device is connected to an optical transceiver 6A of TTL level through those level converting circuits 7 and 8 and then connected to an optical fiber transmission line 17. |
