A splitter is a passive optical device that breaks light into a number of wavelengths to allow several users to utilize a single fiber. Utilizing a single fiber for numerous customers can also be accomplished with active optical devices, such as multiplexors (or a mux), but cost and installation considerations may not make these applicable for all situations. Splitters are also called fiber optic taps or even a last mile tap. They are utilized in passive optic networks (PONs) which are one type of network configuration to deliver fiber to the home (FTTH). A splitter has one or a few input ports and then a larger number of output ports. For example, a 1x8 splitter will have one input port to accept a single fiber and eight output ports that can be used to connect eight customers. Typically, each customer will utilize two wavelengths, one for sending and another for receiving a signal.

Attributes (required fields in red): Type: text - This stores a broad classification for the splitter. This field is not used in any calculations, so it does not need to be limited by the domain values present in the standard data model. Users can remove the domain from this field or create and use a nonstandard domain. This field is not required and should only be kept if it is useful. The Fiber Splitter Type domain is applied to this field. Model: text - This is the manufacturer’s model or catalog number. This is not a required field and should only be kept if it is useful to store this information in your GIS. The Fiber Splitter Model domain is assigned to this field. Manufacturer: text - This is the name of the manufacturer of the splitter. This is not a required field and should only be kept if it is useful to store this information in your GIS. The Fiber Splitter Manufacturer domain is assigned to this field. InstalledBy: text - This is the name of the group or organization that installed the splitter. This field was intended to store the names of contractors, but it could also be used to track the individual employees or internal operations and maintenance groups. This is not a required field and should only be kept if it is useful to store this information in your GIS. The Fiber Contractors domain is assigned to this field. DateInstalled: date - This is the date when the splitter was installed in the field. This is not a required field and should only be kept if it is useful to store this information in your GIS. 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.
