Abstract
An optical network comprises a plurality of transmitting (T.sub.n) and receiving (R.sub.n) terminals; and cross-coupling means (2), the transmitting (T.sub.n) and receiving (R.sub.n) terminals being optically coupled with the cross-coupling means whereby modulated carrier signals transmitted from each transmitting terminal (T.sub.n) are fed to each receiving terminal (R.sub.n) via the cross-coupling means (2). A plurality of first sources (4, 7) of optical signals are grouped together remotely from and optical coupled with the transmitting (T.sub.n) and receiving (R.sub.n) terminals to supply carrier signals and tuning signals to the transmitting and receiving terminals respectively.
