History1841Daniel Colladon demonstrates light guiding in jet of water
120 years later we have lasers
By 1970 we finally have fiber that have a low enough attenuation to be of use in communications
2010 The technologies keep coming giving us better distances , more stable systems and greater capacity.

before coating, preforms can make up to 30 km of fiber from one preform.
When Telstra rolled out its network we had two draw towers in production. Today we only have research (small production) towers in Australia.

Connections in the NetworkThe pigtails are presented on a ribbon fiber which enables us to splice 12 pigtails at a time.
In the case of a 144 pigtails it would take about the same time as 10 single fiber pigtails.

The Design of enclosure to suit Ribbon fiber has posed a few problems. Basically the fiber can not
be laid up the same way as single fiber loose tube, ribbon does not have the same flexibility, as such corning took a new approach with the
“spine” while others have designed new tray to accommodate the ribbon, in all cases the storage
area once used to provide extra cable now accommodates fiber from the tray.

Loss on Optical Fiber
![Page 44: Overview of the two days](https://reader038.vdocuments.site/reader038/viewer/2022103101/568143c9550346895db05650/html5/thumbnails/44.jpg)
Optical Ribbon Fiber in today’s networks 44
Loss on Optical Fiber Rayleigh scattering - Scattering of light caused by index of refraction variations in the
submicroscopic structure of the glass. Absorption -A physical mechanism in fibers that attenuates light by converting it in to heat Manufacturing irregularities - Such as geometric variations in core diameter or circularity,
voids in the glass, defects at the core-cladding interface, and imperfect application of dopants, can cause scattering loss. However, these regularities are usually negligible in present day fibers.
Microbending - Curvatures of the fiber that involve axial displacements of a few micrometers and spatial wavelength of a few millimeters. Microbends cause loss of light and consequently increase the attenuation of the fiber. Loss due to microscopic bends in the fiber.
Macrobending - Macroscopic axial deviation of a fiber from a straight line, in contrast to microbending. Loss due to large bends in the fiber.
