Abstract
A data transmission between a device and a first and a second optical maintenance port involves a transmission reflector in the form of a solid-state bound data line having a gap and a Y coupler. This allows recording of the communication between the device to be read out and the first optical maintenance port in real time by means of the second optical port. Likewise, communication by means of electromagnetic energy is possible between the first and the second optical maintenance ports.

An optical data transmission system comprising:
- a device;
- a first optical maintenance port;
- a second optical maintenance port;
- an optical signal splitter coupled to each of the first optical maintenance port and second optical maintenance port;
- and
- a solid-state bound data line, coupled to the device and the optical signal splitter, the solid-state bound data line configured to transmit data using electromagnetic energy between the device and the first optical maintenance port and the second optical maintenance port, wherein the solid-state bound data line is interrupted by a gap between (i) the device and (ii) the optical signal splitter, wherein the gap is configured to transmit electromagnetic signals between the device and the optical signal splitter, and to reflect electromagnetic signals emanating from the first optical maintenance port to the second optical maintenance port, by way of the optical signal splitter, thereby further enabling data transmission between the first optical maintenance port and the second optical maintenance port.
