Current development

• More and moreQuantity of data increases since more information are exchanged.

• Faster and fasterTime is money. Demand for High-speed.

• Further and further the world is a global village. Networks spread over the whole planet. 

• All-time availabilityInformation is a short-lived consumer good.Always and anywhere accessible.

“highest security in communication networks”

• Communication without limits. • We see it as our task to build the foundation for the

most secure network e.g. passive cabling solution.• Everything we do is focused to maximize reliability of

a communication network.

Optical communication is as old as humanity itself

• hand signals• smoke signals• by optical telegraph

To the optical information technology as we know it today - two developments were crucial:

• The transmission of light over an optically transparent matter

• Availability of the LASER

Introduction

Training_FO_Introductioin_GB Page 10

History – Fiber optic

1840 Swiss physicist Daniel Colladon discovered he could shine light along water pipe. The water carried the light by internal reflection.

1960 Corning Glass Company made first fiber-optic cable capable of carrying telephone signals.

1977 The first fiber-optic telephone cable was laid between Long Beach and Artesia, California.

General

• Material is the core of an optical fiber.• Without ultra transparent material, communication over

fiber optic does no work.

History - Laser

1917 Einstein discovers the theory of „stimulated Emission“

1960 first demonstration of aLaser (Light Amplification by Stimulated Emission of Radiation) by T.H. Maiman

1962 – realization of first Laser diodes (lifetime: few minutes up to some hours, cooling down to -200 °C required)
