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.

1. An optical data transmission system comprising:
a device;
a first optical maintenance port;
a second optical maintenance port;
