Pulling -A system to place cables or ducts for shorter length runs of underground plant and in previously installed underground, buried, and aerial micro-ducts using a winch and winchline. Both ducts and cables can be placed with this pulling method. Pulling tends to be more popular for standard optical cables and in larger diameter communication ducts and innerducts (sub-ducts). Depending upon the pulling method used and the geometry of the conduit plant encountered, lengths of 1,500 to 3,000 feet can be placed using this approach. Jetting (blowing) – A system used in longer lengths of underground cable and in previously installed micro-ducts using air pressure. Standard optical cables, micro-duct cables, and micro-ducts can be placed using jetting. Jetting is most effective in smaller ducts of 50 mm diameter or less (micro-ducts). It is possible to place micro-duct cable using jetting in continuous lengths of 4,000 to 6,000 feet, depending upon the geometry of the right-of-way. The following effects contribute to the pulling force build-up in the cable: Cable weight (gravity)- This results in a pulling force that is proportional to the installed weight of the cable which is directly related to the cable size, design, and the length of the cable. Coefficient of friction- The material property that relates the normal force to frictional force between cable and duct (or adjacent cable when several cables are present in the same duct). The coefficient of friction affects the cable tension linearly in straight runs. In bends and undulations of the duct, the tensile pulling force increases exponentially with respect to the undulation's curvature and the coefficient of friction. This effect is known as the capstan effect. It can dominate most cable pulls.

Cable tensile force- The resulting pulling load on a cable is the combination of cable weight,  curvature of the bends, location of the bends, coefficient of friction, and weight of cable (unit  weight and length). The total cable tensile force required to place the cable must not exceed the rated cable tensile strength.

During the trench warfare of World War I when wire communications were often cut, German signals used three types of optical Morse transmitters called Blinkgerät, the intermediate type for distances of up to 4 km (2.5 miles) at daylight and of up to 8 km (5 miles) at night, using red filters for undetected communications. Optical telephone communications were tested at the end of the war, but not introduced at troop level. In addition, special blinkgeräts were used for communication with airplanes, balloons, and tanks, with varying success.[citation needed]

A major technological step was to replace the Morse code by modulating optical waves in speech transmission. Carl Zeiss, Jena developed the Lichtsprechgerät 80/80 (literal translation: optical speaking device) that the German army used in their World War II anti-aircraft defense units, or in bunkers at the Atlantic Wall.[4]

The invention of lasers in the 1960s, revolutionized free space optics. Military organizations were particularly interested and boosted their development. However the technology lost market momentum when the installation of optical fiber networks for civilian uses was at its peak.

Many simple and inexpensive consumer remote controls use low-speed communication using infrared (IR) light. This is known as consumer IR technologies.
