In addition, this document describes a suggested approach for developing and designing a fiber optic cable topology (FOCT) for a Naval platform and also i
14、dentifies the applicable fiber optic component specifications. This handbook is primarily intended for use by the fiber optic cable topology design engineer, but provides useful information to a systems design engineer as well. 1 Licensed by Information Handling ServicesProvided by IHSNot for Resale

NRC - Non Redundant Channel 3.2 Definitions. Definitions for general fiber optics terms used in this handbook are in accordance with EIA
28、/TIA-440. Definitions for other terms as they are used in this handbook are given in the following paragraphs. 3.2.1 Allocated and used fiber. An allocated and used fiber is a fiber that is designated and required for use for a particular system link, and is being used to transmit information. Alloc
29、ated and used fibers include fibers used for normal channels, fibers for alternate channels, and fibers for non redundant channels. 3.2.2 Allocated and not used fiber. An allocated and not used fiber is a fiber that is designated for use for a particular system, but is not being used to transmit inf
30、ormation. Allocated and not used fibers include fibers allocated as system spare fibers, system growth fibers, and system redundant fibers . 3.2.3 Alternate channel. An alternate channel is the allocated and used active backup link for a normal channel. 3.2.4 Fnd user eauiDment. End user equipment r
31、efers to any cabinet, case, panel, or device that contains components that are either the origin or destination of an optical signal. 3.2.5 Fiber oDtic cable dant. The fiber optic cable plant consists of the fiber optic interconnection boxes, trunk cables and the connectors and splices used to termi
32、nate the trunk cables. 3.2.6 Growth fiber. An unallocated fiber intended for later use in the installation of fiber optic systems after initial ship construction. 3.2.7 Intermediate interconnection box. An interconnection box in which two trunk fibers are interconnected. 3.2.8 hocal cab fiber and ca
33、ble type, termination requirements, fiber optic performance requirements; as well as additional general requirements that will shape the configuration of the FOCP and FOCT. 4.2.2 FOCT confiauration. After all the input requirements are determined, a FOCT configuration may be developed. the platform

The FOCT design process invol
36、ves a three phase approach: conceptual, preliminary and detailed (see figure 2). As each phase is completed the output from that phase becomes part of the input to the next phase. information and requirements are modified. An optimal configuration with the appropriate documentation necessary to spec
37、ify and install a FOCT is the final output of the detailed design phase. Each design phase may be repeated as the ship system and ship design 4.3.1 Conceptual desian. The conceptual design phase is used to develop an initial FOCP configuration. The inputs to this design phase are: a. Ship specificat
38、ion b. Ship configuration information c. System specifications d. Conceptual design guidelines (see 5.2.1) These inputs can be used to determine the general location of interconnection boxes and the compartments that the interconnection box will service (service areas). General interconnections betw
39、een interconnection boxes can be identified, determining the trunk requirements for the FOCP. A FOCP block diagram can be developed and is used as an input in the preliminary design phase. If required, this information may also be depicted on an isometric cabling diagram. Typical outputs of the conc
40、eptual design phase are: a. Service area definition b.
