A data handling system comprising a multiplicity of data processing modules (5a - 5e) releasably retained in a racking system (1) and an optical data link arrangement (13) interconnecting the modules (5a - 5e), the optical data link arrangement comprising an elongated light path in the form of one or more light transmissive bars (21, 23) interconnecting the modules (5a - 5e) and to which the modules (5a - 5e) are coupled by way of reflection at respective partially light reflective, partially light transmissive members extending across the light path. In the embodiment of Fig 1, bar 21 is used for transmission only, bar 23 being used for reception. In an alternative embodiment a single bar is used for transmission and reception. The bars may be replaced by hollow tubes. If the modules are not aligned a flexible bar may be used (Fig 6 not shown). Signalling may be effected using TDM or WDM. <IMAGE>
