Abstract
An optical forwarding device includes a specific optical connector and an optical forwarding module. The optical forwarding module includes first and second optical connectors, first and second wavelength division multiplexers (WDM), and an optical circulator. The first WDM receives and forwards a first optical signal from the first optical connector. The optical circulator includes first, second, and third ports. The first port forwards the first optical signal from the first WDM. The second port forwards the first optical signal from the first port to the optical cable through the specific optical connector, and receives and forwards a second optical signal from the optical cable. The first and second optical signals have a first wavelength. The third port receives and forwards the second optical signal from the second port. The second WDM receives the second optical signal from the third port and sends the same to the second optical connector.
