This standard practice provides detailed methods for installingoptical fiber cable cableways and cable protection on surface ships and submarines.1.1.1 Applicability. These criteria apply to instal

20、lations on specific shipswhen invoked by the governing ship specification or other contractual document.They are intended primarily for new construction; however, they are also applicablefor conversion or alteration of existing ships. The rapidly changing state of theart in fiber optic technology ma

21、kes it essential that some degree of flexibility beexercised in enforcing this document. When there is a conflict between thisdocument and the ship specification or contract, the ship specification or contractshall take precedence. Where ship design is such that the methods herein cannot beimplement
