Type:	Class		Stereotype:	«XSDcomplexType»

A single segment of the optical fiber used for distributed temperature surveys. Multiple such segments may be connected by other types of components including connectors, splices and fiber turnarounds.

Table 29.5.24-1 Attributes
Name	Type	Notes
CableType	CableType	Enum. The type of cable used in this segment. Example: single-fiber-cable.
CladdedDiameter	LengthMeasure	The diameter of the core plus the cladding, generally measured in microns (um).
Coating	String64	The type of coating on the fiber.
CoreDiameter	LengthMeasure	The inner diameter of the core, generally measured in microns (um).
CoreType	String64	Property of the fiber core.
FiberLength	LengthMeasure	The length of fiber in this optical path section.
Jacket	String64	The type of jacket covering the fiber.
Mode	FiberMode	The mode of fiber. Enum. Values are single- or multi- mode fiber, or other/unknown.
OutsideDiameter	LengthMeasure	The diameter of the cable containing the fiber, including all its sheathing layers.
OverStuffing	LengthMeasure	For this fiber segment, the amount of "overstuffing", i.e., the excess length of fiber that was installed compared to the length of the facility that is to be surveyed. Example: if 110 m of fiber were to be installed to measure 100 m length of pipeline, the overstuffing would be 10 m. Overstuffing can be allowed for in the facilityMapping section. The overstuffing is assumed to be linear distributed along the facility being measured.
Parameter	IndexedObject	Additional parameters to define the fiber as a material.
SpoolLength	LengthMeasure	The length of the fiber on the spool when purchased.
SpoolNumberTag	String64	The spool number of the particular spool from which this fiber segment was taken. The spool number may contain alphanumeric characters.
