Abstract
A repeater (1) includes a master unit (2) for communicating with a base station of a mobile network, a plurality of remote units (3) for communicating with mobile communications terminals, and a common optical waveguide (4) connecting the remote units (3) with the master unit (2) for transmitting the optical signals from each of the remote units (3) to the master unit (2). The remote units (3) include, as a transmitter for the optical signals, a laser (7) of a construction similar or somewhat identical to that of the other lasers (7). The lasers (7) have similar or somewhat identical nominal wavelengths (λN), and the individual lasers (7) are selected by adjusting their operating temperatures (TD1-TD4) in such a way that each laser transmits on a different transmission wavelength (λü1-λü4).
