BufferTube

In the field, buffer tubes are used to group, protect and identify fibers within a cable. In Fiber Manager, buffer tubes are used to display fibers within their designated groups and identify specific fibers (Blue Buffer/Blue Fiber = Fiber 1, Blue Buffer/Orange Fiber = Fiber 2,…) within a cable. In the field, buffer tubes may not always be plastic sleeves that surround glass fibers. They can also be threads wrapped around fibers (OPGW Cables), stainless steel tubes (OPGW Cables), plastic notches in a helical divider (European Cables), or even painted marks on fibers (underground and submarine cables). The Buffer Tube (F_BufferTube) object is a required part of the data model. Even if a cable does not have a true buffer tube, the identification scheme of the cable will need to accommodate the buffer tube object.

Attributes (required fields in red):

BufferTubePosition: long integer - This field tracks the order in which the buffer tubes should be listed. This field is used by the Fiber Manager application and allows for non-conventional buffer tube colors and order.

BufferTubeNumber: long integer - This field allows for a tube number that differs from the tube position.

BufferTubeColor: text - This is the color of the buffer tube. This field is set by values in the Fiber Colors domain and can configured to be any color. The values in this domain can be expanded to include unconventional colors and stripes of any color.

BufferTubeName: text - This is a short (two character) name to denote the color of the buffer tube. This name is used in various reports. The Fiber Color Names domain is assigned to this field.

GlobalID: GlobalID - This field contains a unique number (GUID) that is generated and maintained by ArcGIS. This value is used for all relationships in the ArcFM data model and is required for Fiber Manager to function properly.

FiberParent: GUID - This field contains the GlobalID of the parent object to the current object.

ThisFiberClassModelName: text - This field stores the class model name assigned to the feature class on which the field resides. It is used in conjunction with the FiberParentClassModelName field to determine the GlobalID that will be placed in the FiberParent field.

FiberParentClassModelName: text - This field stores the class model name assigned to the feature class that is the parent of the class on which the field resides. It is used in conjunction with the ThisFiberClassModelName field to determine the GlobalID that will be placed in the FiberParent field.

FiberChildClassModelName: text - This field stores the class model name of a child object to the object on which the field resides.
