<p>The device (1) has a conversion module (8) arranged to perform bidirectional conversion between first and second optical signals (S2, S3) occupying a first electrical communication band. A transfer module (10) is arranged to transfer a third optical signal (S1) between connectors (2, 6) in a second communication band. A power supply module (11) is arranged for providing electrical power from a supply voltage (POE) received in the third connector in a third communications band, which is separated from the first and second communication bands.</p> |
