3GIS Terms

Fiber placement rules

1. Fiber cables should be placed as single linear features from Splice to Splice located at Structures. Cables should only be broken when going from Underground to Aerial or Aerial to Underground and must take place at a Structure - a transition splice should be placed for connectivity. 2. DIRECT BURIED CABLE: A Direct Buried Span should be placed over the Direct Buried Cable. 3. Relationships - a. Splice Closures: 1 Fiber cable can have 0 or 1 to many Splice Closures. b. Span: 1 Fiber cable can have 0 or many to many Spans. c. Structure: 1 Fiber cable can have 1 to many Structures. d. Slack Loops: 1 Fiber cable can have 0 or 1 to many Slack Loops.

PON

A fiber-optic telecommunications technology for delivering broadband network access to end-customers.

FDH Connections

All necessary connections will be made automatically by the system • TAIL (Feeder) to HUBIN Input • HUBIN Output to SPLITTER Input • SPLITTER Output to HUBOUT Input (will be handled by iVAPP) • HUBOUT Output to TAIL (Distribution)

OLT

An optical line termination, also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).

FDHT

Combines the functionality of a FDH and a FDT into a small convenient package (the same size as an FDT). The FDHT comes with a single 12 fiber tail that is available in different lengths. The first four fibers are terminated for use in connecting to splitters. The remaining eight fibers are terminated on the right hand side of the panel for use as pass through and are labeled 5-12 PX and are terminated on SC type connectors for Non-PON type services. The Split fibers are terminated on the left hand side of the panel and numbered 1-32 terminated on SC type connectors where jumpers plug directly into them for PON type distribution. This product is perfect for feeding small strip malls (Can be used indoors or out and is perfect for rear wall applications) or in office buildings with 32 or fewer units. It can also be used in areas in need of fiber relief or where a full size hub cannot be placed. See NP-IL-2018-0080 for more details. To place this feature you must first place a FDAT. The FDAT is similar to a PSA in that it is a polygon that is used to associate the demand points to the serving FDHT. When placing the polygon, it must include the all the intended demand points. There may be instances where more than one FDHT can be placed and sublocs split between them.

Complement Creation

Complement creation is required when splicing a fiber tail or fiber cable from an FFDF (feeder cable) or from an FDH (distribution cable)

What is an FQN ID?

FQN stands for Feature Qualifier Name/Number and it is a unique feature identifier. The system will automatically generate and assign a unique FQN ID for each and every feature created and placed in VZ-3GIS. The FQN ID is typically made up of a text value to indicate feature type or environment in addition to a numerical value. For example, for a Fiber Buried Cable the FQN ID format will be as follows: FIB: BUR::123456.

High Level Design

Fiber Security Process

It is the responsibility of the VZ engineer to submit a fiber security shape file at each of the design stages - High Level, Detail Design and AsBuilt. The Verizon Engineer should follow process below after approving a Market Vendor design that includes subsurface linear features. Any changes to existing fiber cable or FSRV running lines, any fiber cable or FSRV deletions or any newly placed fiber cable that is drawn in VZ 3GIS needs to be extracted from VZ 3GIS and sent to OSP Documentation so that it can be uploaded to the One Call centers to ensure the fiber cable is covered in the One Call databases.

Optical Distribution Network (ODN) Design

ODN: Connects the ONTs to the OLT and provides the optical paths over which they communicate. Feeder fibers carry optical signals from the OLT into the loop. Each feeder fiber strand is connected to an optical splitter located in a FDH. In a centralized split architecture, the splitter divides the signal into 32 or 16 output ports. A distribution fiber can be connected to each output port. These fibers are then distributed throughout the distribution network through the use of FDTs. Upon a service order request, a fiber drop is then placed between a FDT and the location where it is terminated in an ONT. The ODN contains only passive components. Additionally, pass-thru capacity and express port modules (EPMs) at the FDH provides the ability to bypass the splitter in the FDH and directly jumper feeder to distribution fibers to support the provisioning of non-PON services.

Splice Closure placement rules

Required Attributes 1. OWNER: Defaults to 'MCI Metro' (can be changed if appropriate) 2. TYPE NAME: Select type of closure - splice closure or transition splice (See 14.6.1 for more information on Transition Splice) Placement Rules 1. Splice Closures that are housed in Structures (Handholes / Manholes / Pullboxes) should be placed inside that Structure and snapped to the end of the Fiber cable line. 2. Aerial Splice Closures are point features which should be positioned near the pole and snapped on the Fiber cable line. 3. A Splice Closure should be placed where a 2-way or 3-way Splice occurs. Two Splice Closures are only required where (2) independent 2-way Splices occur in the same Structure. a. If 2 or 3 sections of cable are sharing the same complement of fiber strands, then one Splice Closure is required. b. If 4 sections of cable are sharing 2 different sets of fiber strands, then 2 Closures would be required. c. Where there are two Fiber cables with the same fiber count, then one to one connections should be made. Splice closure connections need to be verified. d. Splice direction should mirror the direction of engineering for each project. (i.e. If the project is engineered from East to West, then the connections should be connected East to West). 4. Relationships - a. Structure: 1 Splice Closure can have 1 Structure. b. Fiber cable: 1 Splice Closure can have 2 to many Fiber cable.

Physical Serving Area (PSA)

The PSA is a polygon that is used to define service level attributes for a demand point. It also associates the demand point to the serving terminal.

Slack Loop Types

There are two types of slack loops (slack coil), underground slack and aerial slack. The slack loop layer consists of Verizon Owned slack coils that were captured from AsBuilt. The slack loop symbology is based on the type of slack coil placed (aerial or underground) and the status of the slack loop (existing, proposed or abandoned). The slack loop layer should accurately reflect of the placement and the footage of the coil. A single slack loop can be associated to one fiber cable and must be associated to a structure. If there is a discrepancy in the slack loop placement or footage a correction should be made. UG Slack and Aerial Slack are snapped to the vertex or edge of a fiber cable.

Slack Loop

These coils are very useful for repairing a cable when it has been damaged or for connecting new fiber optic cables to the network.

Replace Tool

This tool will provide the ability to replace a feature with a new Material code selection without having to delete and redraw the feature.

Relationships Spans

a. Structure: 1 Span can have zero or 1 to many Structures. b. Fiber cable: 1 Span can have 0 or 1 to many Fiber cable

Spans/Duct Structures

are linear features and should be placed from and to Structures - all Spans need to have a "From" Structure and a "To" Structure relation.

Transition Splice

is a point feature that is placed when there is a change in fiber cable type (example: buried to aerial, buried to direct buried) when connectivity is required between two same fiber count fiber cable. The Transition Splice layer consists of both Verizon Owned and other Transition Splices that were captured in VZ 3GIS. The Transition Splice symbology and color is based on the type of splice closure placed (splice closure or Transition Splice) and the status of the Transition Splice (existing, proposed or abandoned). A one to one connection should exist between two Fiber cables. One Transition Splice should only have two cables related and spliced. Only like cables (e.g., 24 to 24, 48 to 48, and 96 to 96) should be related and connected.

Splice Closure

is a point feature that should be placed in a Structure. The spice closure symbology and color is based on the type of splice closure placed (splice closure or virtual connection) and the status of the splice closure (existing, proposed or abandoned). Can be associated to one-to-many fiber cable and must be associated to a structure. If there is a discrepancy with the splice closure placement or connections a correction should be made.

Fiber cable

is defined as fiber optic cable. The Fiber cable layer consists of both Verizon Owned and Verizon Leased cables. The fiber cable (cable) symbology and color is based on the type of cable placed (aerial, buried, direct buried, building, fogwire, submarine and leased), and the status of the cable (existing, proposed or abandoned).

Slack Loop Placement rules

Placement Rules 1. A slack loop should be placed for each distinct instance of slack ("coil") encountered along the fiber cable route. 2. The slack loop is a point feature be snapped to the corresponding fiber cable. 3. The type of the slack loop will derived from the associated fiber cable. 4. The Slack feature should be placed on the cable it is related to. 5. Relationships - a. Structure: 1 Slack Loop can have one and only one Structure. b. Fiber cable: 1 Slack Loop can have one and only one Fiber cable.

Span

is defined as Underground span (buried conduit), aerial span (aerial strand), direct buried span (for direct buried cables only) and leased span (for leased cables only). The Span layer consists of both Verizon Owned and Verizon Leased spans captured in VZ 3GIS from AsBuilt. The span symbology and color is based on the type of span placed (aerial, buried, leased, direct buried) and the status of the span (existing, proposed or abandoned). The span should be shown on the correct side of the street/railroad centerline and crossing the street/railroad centerline at the correct location. The span should have the correct conduit size/configuration with accurate information for the attributes. The span should reflect the correct ROW (Right-of-Way) information as captured in the As-Built. VZ 3GIS currently has 8 ROW designations (Leased, Unknown, Public ROW, Railroad, Power, Pipeline, Private Easement and Public Easement). A single span segment should be associated to zero-or-one-to-many fiber cable. Spans typically begin and end at a structure or endpoint of another span. If there is a discrepancy in the span route a correction should be made.

Fiber Equipment

is defined as the equipment where the fiber cable terminates at an equipment site and should exist in all generic buildings serviced by VZB fiber cable. A fiber equipment is required to be snapped to the end point of fiber cable within building. Fiber equipment are to be associated to fiber cable and building (point feature).

Direct Buried

is placed with Direct Buried cable ONLY. The span will be placed from Structure (HH, MH, etc.) to Structure. Direct Buried Span will not be indicated on the AsBuilt; it is a special placement feature with direct buried cable.

Leased Span

is placed with Leased Cable only. The span will be placed from Structure (HH, MH, etc.) to Structure. LSPAN will not be indicated on the AsBuilt; it is a special placement feature with leased cable.

Splicing

joining two fiber optic cables together.

Splitting Fiber Cable

represents a physical split in the cable and it can account for a vertical riser. Splitting a cable can only be completed where a structure is present.

Aerial Strand

should be placed as one linear feature from the starting Pole at which the cable becomes aerial and to the ending Pole at which the cable becomes underground - the Strands do not get segmented between each pole. The Strands should snap to the center of all poles.

Underground Span

should be placed from structure to structure and should not be broken in between. For Example, 3-4" PVC E/W 2-1" HDPE would indicate that the duct structure has 3-4" PVC conduits that contain 2-1" HDPE Innerducts. For the Span in this case, the number 3 would be the Duct Count; 4" would be the Duct Size and PVC would be the Duct Material. For the Innerduct; the number 2 would be captured in the Innerduct Count Field - the size (1") and material (HDPE) does not get captured.

Drawing/Editing while in a Work Order

• All structures must be placed first • Fiber cables must start and stop at structures. Where multiple cables exist inside the same Duct Structure, those cables should be placed on top of each other. • Spans (Aerial, Buried and Direct Buried span) typically start and stop at structures (Handhole/Manhole/Pullbox / Poles) but not required. Where a Span ends at a building, the Span should snap to the building footprint edge.

VFDT

• Is a virtual terminal that is used as a place holder for future opportunities and or network extensions. • It can be used for Feeder or Distribution fiber cables. • It needs to be associated with a slack loop, a splice closure and a structure. • To begin placing this, a splice closure needs to be present either at the end of a cable run or at a slack loop location. • A splice closure can be added to the design via the Split Linear function. • During placement of the item, user will have the ability to reserve fibers on the associated fiber cable.
