Abstract

A switch architecture in which a set of n smaller switches (10) are interconnected by means of a core controller (12) and an optical shuffle (16) to form a big switch. Each smaller switch has transmitter block (14) with n laser diodes (14a) connected by an n-fibre ribbon (15) with the shuffle, and a detector block (18) similarly connected with the shuffle. The core controller selects not more than one laser diode of any smaller switch to transmit at any one time.
