17、from IHS-,-,-MIL-STD-2042-3B(SH)11.SCOPE1.1 Scope. This standard practice provides detailed methods of optical fibercable penetrations through ship structure and equipment via stuffing tubes, swagetubes, multiple cable penetrators, chafing collars and nipples.1.1.1 Applicability. These criteria appl
18、y to installations 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 te
19、chnology makes 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
20、beimplemented, users shall submit new methods or modifications of existing methods forapproval prior to implementation to: Department of the Navy, Naval Surface WarfareCenter, Dahlgren Division, ATTN: Code B35, 17320 Dahlgren Road, Dahlgren, VA 22448-5100.Provided by IHSNot for ResaleNo reproduction

Definitions for general fiber optics termsused in this standard practice are in accordance with EIA/TIA-440. Definitions forother terms as they are used in this standard practice are given in the following
39、paragraphs.3.2 Chafing collar. A chafing collar is a round or oval banding that protectstwo or more cables that penetrate structure from crimping and wear caused by rubbingagainst sharp edges.3.3 Collective protection system (CPS). A CPS system is a system designed toinhibit the entry of chemical, b
40、iological, and radiological contaminants intocollective protection zones on board Naval ships.3.4 Kickpipe. A kickpipe is a pipe welded into the deck with a stuffing tubeattached. Kickpipes provide protection for cables at deck penetrations and are usedto clear an obstruction or preserve alignment.3
41、.5 Metal stuffing tube. A metal stuffing tube provides a means for makingwatertight single cable penetrations through shell plating, decks, and bulkheads,and into equipment.3.6 Multiple cable penetrator (MCP). A MCP provides a means for makingwatertight, airtight, and firetight penetrations through
42、decks, bulkheads, and intoequipment.3.7 Nipple. A nipple is a smaller version of the chafing collar, and is usedto protect a single cable penetration.3.8 Optical fiber cable. A cable that contains optical fibers.3.8.1 BOF cable. A cable that contains one or more BOF tubes through whichoptical fibers
43、 or optical fiber bundles are blown.3.8.2 Conventional optical fiber cable. An optical fiber cable in which theoptical fiber is an integral part of the cable and is installed during the cablemanufacturing process.3.9 Swage tube.
