Abstract: There are many legal issues which are relevant to fibreoptic cable systems. This article deals with just a few of them, but concentrates on the current industry concerns with insolvency. It argues that too much weight is put on the term “IRU” (indefeasible right of use) in the industry and that, really, to understand the effect of owning an IRU you must, always, look at the contract - there’s no magic to owning an “IRU” - you simply own a bundle of contractual rights.
