Bentley Fiber

Multiplexing (DWDM/CWDM)

Bentley Fiber supports the multiplexing and de-multiplexing of wavelength for use in commercial fiber and HFC architectures. This functionality is available in splice enclosures, OSP node chassis, and is fully supported by Bentley Inside Plant.

Wavelength can be de-multiplexed at the node chassis or just outside the chassis and associated with specific receivers and transmitters. Circuit IDs can be assigned to each wavelength and rippled throughout the network for reporting and rendering by the GIS.

Splicing

Bentley Fiber allows efficient fiber cable splicing automatically or manually, depending on the complexity of your network. From an easy-to-use GUI, you can select fibers to splice together, the type of splice to use, the position they will occupy in the enclosure, their status, tray/slot/holder location, and fiber entry port allocation for the incoming sheaths. MUX and splitter devices can also be added and associated with tray slot and holder locations. Documenting the real splice position in the enclosure helps prevent costly mistakes in the future. Once constructed, save the splice loss measured in the field for different wavelengths to use for further engineering calculations.

Once fibers are spliced together, you can associate a circuit name to the newly created optical path. For each of these optical systems, wavelengths that carry customer signals can be associated. Connections can also be made inside a cabinet for fiber-to-fiber connection, fiber-to-patch panel, or fiber-to-splitter connection. 

Tracing

Bentley Fiber, in conjunction with Bentley Inside Plant, completely models a fiber network end-to-end. The fully connected network model allows users to trace from the physical port of fiber at the headend or central office all the way to the subscriber and vice versa. The model is essential to operations and engineering and a number of capabilities are provided in Bentley Fiber to facilitate their work.

The network model can be traced and analyzed at the sheath and fiber level. Users can visualize the fiber or optical system path on a map, review distance and budget loss, and use the model in strengthening the network with fiber redundancy. Users can also easily determine who is affected by a fiber problem or a card malfunction in a building. The open, detailed model facilitates working hand-in-hand with OSS systems. Operations personnel benefit from integration with a network monitoring system when fiber faults are visually located on the detailed fiber maps created by Bentley Fiber and the integration ensures the common model is always up-to-date. The information may be used in field applications such as work force management or in any of the upstream processes, such as network provisioning.

Engineering Calculations

Bentley Fiber accommodates all the requisite fiber architectures, including FTTx, and provides detailed engineering calculations that can be performed interactively as an integral part of the design process. There is no need to translate the model into a third-party application. The intelligent network model enables engineering calculations such as loss budget analysis, laser selection, and optical coupler optimization, to be performed on a geographic area or across the entire network. These tools help you choose the right transmitter and coupler for every node.

Bentley Fiber performs loss calculations on a fiber network for different wavelengths. The value and quantity of wavelength that can simultaneously be tracked is easily configurable with the Engineering Calculations menu.

Operations Functions

Quickly find any device, locate an outage anywhere in the network, locate a path between two devices based on a number of criteria, or locate customers. Users have access to handy locate functions including locate device by several methods: locate customer, locate slack, and locate outage. Locate outage locates a fault in the fiber by using distance measured from an OTDR. The Locate Outage function offers you the option of viewing all the customers affected by the outage and other pertinent information. This enables operations staff to find customers in an emergency in seconds and to view the location of the problem in a spatial context to make decisions regarding crew dispatch. Operational functionality for FTTx architectures includes activating an address, assigning a port for service at the cabinet, confirming customer activation, and assigning a serial number to the ONT at the home, work order generation, and port allocation notices at the cabinet location.

Reports and Diagrams

Bentley Fiber generates customizable .xls template bills of material reports (BOMs), reel ordering reports, and intelligent splicing documentation for use in downstream work processes. Reports are displayed on the screen and may be output as text files for printing or import to other systems.

Various reports are available, including a resource report that details the equipment specifications, a device information report with the properties of the routed equipment, a device bill of materials that lists the materials and costs of equipment used on current work or in an entire project, a sheath BOM report of the active work or an entire project, and a reel BOM assigns sheaths to reels on the active work or an entire project.

Splice connection reports may also be generated along with splicing diagrams. Splicing reports may be generated for single splice location, showing fibers and connections throughout the entire path of selected splice, or for the entire network. The splicing diagrams show color-coded fibers and connections. Create different kinds of enclosure diagrams just by clicking on the enclosure.

Strand and Facilities

Bentley Fiber uses a graphical routing process based on existing GIS features and strand map information to build an intelligent geospatial model of the fiber and related outside plant.

Strand mapping specifications are completely configurable, including options to control all drawing tools. Because symbology is database driven, it is updated automatically as properties are modified. Fast and easy tools are provided for placing poles, pedestals, ducts, manholes, handholes, conduit, and other structures. Intelligent editing maintains relationships, recalculates lengths, and ensures wholeness. Grounds, down guys, anchors, and other equipment may be added. Information can also be imported from field surveys. Addresses, multi-dwelling unit counts, commercial counts, and other relevant information can be easily added with flexible placement options. Intelligent addresses may be automatically associated to structures and either keyed-in or selected from pick lists generated from billing or other OSS systems.

Users may choose from several types of GIS formats for their mapping foundation to be either referenced or added to the Oracle database and rendered as features from the database with Bentley Map. Bentley Fiber provides the ability to generate a strand BOM report for individual equipment, a project, or a geographic area. The report details lengths, house/MDU/commercial counts, strand information, addresses, and other information.

Duct Management

Bentley Fiber provides the capability to route and manage conduit within a duct system and to perform capacity analysis. Conduit bundles can be created to accelerate duct layout between enclosures. Bentley Fiber provides access to the duct system by modeling enclosures such as manholes or handholes. All aspects of duct management are configurable to meet company standards.

Each conduit may be assigned to a company and color coded for clarity. In addition to fiber, coax and/or copper are easily routed through the system when using the Bentley Coax and Bentley Copper products. Users may produce elevation views, wall diagrams, and cross-section views where cables are color-coded to clearly display the content. Cross section views are dynamically generated from the database so that users can interact with the view to review ownership and lessee information on cables within the conduit, move cable from one duct to another, or delete duct elements.

Users can also generate a duct bill of material report within a geographic area or project. Sequence or butterfly type wall diagrams for single or multiple enclosures can be generated and output to separate drawing files if requested.

Work Prints

Integrated Bentley Map print preparation tools can be used to facilitate construction plans. Network information is clipped from the master model and pasted into a print preparation model for finishing. The print preparation capabilities include border placement, legend creation, detail view representation, and many more features. You can add construction notes, scale the network information as appropriate, and add many other items typically found in work prints. The network items placed in the model during print preparation contain XML fragments that carry the intelligent network device and facility properties and these can be reviewed at any time. As such, work print drawings are self contained, meaning that the graphical and property information, as well as other metadata, are contained in a single, portable file.

Print preparation functionality is delivered with a standard schema and sample border templates and other items. This facilitates quick startup, but print preparation is also fully customizable to meet your organization's standards
