摘要
The invention relates to an optical coupling unit for an arrangement for sending optical signals, comprising a base unit (7), a light path (8) formed between a light input (6) and a light output (9) of the base unit (7) and configured to transmit light received via the light input (6) to the light output (9), an outer light path section (15) included in the light path (8), which section extends outside the base unit (7) and into which the light transmitted along the light path emerges from the base unit (7) via a light exit (14) and from which the light after passing through the outer light path section (15) enters again into the base unit (7) via a light entry (16), and a light- decoupling element (11), which is formed in the light path (8) by means of at least one beam- splitting surface coating and configured to decouple a portion of the light transmitted along the light path. Furthermore the invention relates to an arrangement for sending optical signals and to an optical transceiver.
