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.

from sand to a light pipeSilicon dioxide – SiO2

One of our most abundant oxide in the worlds crustAs a point of interest Australia has a major producer “Simcoa Operations” in Western Australia.

Silicon production commenced in December 1989. Today Simcoa is capable of producing in excess of 33,000 tonnes of high purity silicon annually.

from sand to a light pipeDraw towers convert the preform into the fiber

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.

The 125um raw fiber is coated wth 250um buffer first then 900um for cord and raiser applications. In ribbon it is only coated with 250um prior to bonding or lamination

Cable Preparation

Cable preparation varies with depending on the manufacturer and the type of cable. The video from Prysmian is a resent run and give you a good idea

of the accepted practice.

Connections in the NetworkTypical connection we have are Patch leads at both ends of the network, Fusion splicing in Universal enclosures, Field Pluggable network connections, Central

office or exchange Pigtails.

Starting at the Exchange, Central office or Field Access Node we have mass spliced

pigtails in the racks

Optical Ribbon Fiber in today’s networks 24

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.

Connections in the Network

Optitip and Optitap are a field ruggedized connection that is being used in FTTH

While some applications need the tube fanned out in the rack, the unit shown has individual tubes for each fiber.

Loss on Optical Fiber

Page 44: Optical Ribbon Fiber in todays networks 1. Overview of the two days Day One 8.30am Registration and coffee 8.45am Welcome and workshop overview Max Wilson.

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.
