This standard provides detailed methods for the installation offiber optic cable topology equipment (see
28、 3.16), and optical fiber cable entry tofiber optic cable topology and other equipment.1.1.1 Applicability. These criteria apply to installations on specific shipswhen invoked by the governing ship specification or other contractual document.They are intended primarily for new construction; however,
29、 they are also applicablefor conversion or alteration of existing ships. The rapidly changing state of theart in fiber optic technology makes it essential that some degree of flexibility beexercised in enforcing this document. When there is a conflict between thisdocument and the ship specification
30、or contract, the ship specification or contractshall take precedence. Where ship design is such that the methods herein cannot beimplemented, users shall submit new methods or modifications of existing methods forapproval prior to implementation to: Department of the Navy, Naval Surface WarfareCente
