The CIM_PhysicalLink class represents the cabling of physical elements together. For example, serial or Ethernet cables, and infrared Links would be subclasses (if additional properties or associations are defined) or instances of CIM_PhysicalLink. In many cases, the numerous physical cables within a physical package or network will not be modeled. However, where these cables or links are critical components, or are tagged assets of the company, these objects can be instantiated using this class or one of its descendent classes.
'The current length of the physical link in feet. For some connections, especially wireless technologies, this property may not be applicable and should be left uninitialized.'

True
Units
'feet'
Length property is in 1 class (CIM_PhysicalLink) of ROOT\cimv2 and in 5 namespaces
'The MediaType property defines the particular type of media through which transmission signals pass. Common network media include twisted-pair (value=11 or 12), coaxial (7, 8 or 9) and fiber-optic cable (10).'
'CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.'
'The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.'
'The name of the organization responsible for producing the physical element. This may be the entity from whom the element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.'
'OtherIdentifyingInfo captures additional data, beyond asset tag information, that could be used to identify a physical element. One example is bar code data associated with an element that also has an asset tag. Note that if only bar code data is available and is unique/able to be used as an element key, this property would be NULL and the bar code data used as the class key, in the tag property.'
'The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.'
'An arbitrary string that uniquely identifies the physicalelement and serves as the element's key. The Tag property can contain information such as asset tag or serial number data. The key for CIM_PhysicalElement is placed very high in the object hierarchy in order to independently identify the hardware/entity, regardless of physical placement in or on cabinets, adapters, etc. For example, a removable component that can be hot swapped, may be taken from its containing (scoping) package and be temporarily unused. The object still continues to exist - and may even be inserted into a different scoping container. Therefore, the key for physicalelement is an arbitrary string and is defined independently of any placement or location-oriented hierarchy.'
