OPTICAL TRANSMISSION DEVICE AND METHOD FOR DETERMINING CONNECTION |
| 摘要 |
There is provided an optical transmission device including: a first coupler to which an optical signal including an amplified spontaneous emission is input; a first filter configured to transmit the optical signal having a first frequency band from the first coupler; a first optical detector configured to detect an optical intensity of the optical signal transmitted through the first filter; a first port coupled to the first coupler; a second port configured to be coupled to the first port; a second coupler coupled to the second port; a second filter configured to transmit the optical signal having a second frequency band matching the first frequency band from the second coupler; and a reflector configured to reflect the optical signal from the second filter. |
