HYBRID CHANNEL COMMUNICATION

摘要

There is provided a method for facilitating communication over a communications link. The link comprising a hybrid signal channel provided between two locations, the channel comprising a first portion (4) arranged for carrying electrical signals and a second portion (2) arranged for carrying optical signals. The method comprises the steps of: allowing application of electrical signals to the first portion (4) of the channel at a first of the two locations; receiving the electrical signals at an interface between the first and second portions of the channel; and applying signals to the second portion (2) of the channel using optical signal applying means (8). The step of applying signals to the second portion (2) includes the step of using the electrical signals received at the interface to modulate the output signal of the optical signal applying means (8).
