Cable Length

A cable length or cable's length is a nautical unit of measure equal to one tenth of a nautical mile or 100 fathoms, or sometimes 120 fathoms. The unit is named after the length of a ship's anchor cable in the age of sail. The definition varies:

  • International: 1⁄10 nautical mile, or 185.2 m
  • Imperial (Admiralty): 1⁄10 Admiralty mile, or 608 ft (185.32 m), about 101 fathoms
    • The traditional British fathom varied from 5½ feet to 7 feet in the Merchant Navy.
  • U.S. customary (US Navy): 120 fathoms (720 feet, 219.456 m)

Differential Pair - High-voltage Differential Signaling
... SCSI-1 variations included a high voltage differential (HVD) implementation whose maximum cable length was many times that of the single-ended version ... SCSI equipment for example allows a maximum total cable length of 25 meters using HVD, while single-ended SCSI allows a maximum cable length of 1.5 to 6 meters ... LVD versions of SCSI allow less than 25 m cable length not because of the lower voltage, but because these SCSI standards allow much higher speeds than the older HVD SCSI ...
Optical Time-domain Reflectometer - Description
... An OTDR may be used for estimating the fiber's length and overall attenuation, including splice and mated-connector losses ... OTDRs are commonly used to characterize the loss and length of fibers as they go from initial manufacture, through to cabling, warehousing while wound on a drum ... For example, using a long pulse length, it may possible to measure attenuation over a distance of more than 100 km, however in this case an optical event may appear to be over 1 km long ...

Famous quotes containing the words length and/or cable:

    Men sometimes speak as if the study of the classics would at length make way for more modern and practical studies; but the adventurous student will always study classics, in whatever language they may be written and however ancient they may be. For what are the classics but the noblest recorded thoughts of man?... We might as well omit to study Nature because she is old.
    Henry David Thoreau (1817–1862)

    To be where little cable cars climb halfway to the stars.
    Douglass Cross (b. 1920)
