The main purpose of the transmitter is to convert electrical signal to light signal. This light signal will pass through the medium (fiber optic cable) and will reach the receiver.
The medium is fiber optic cable (foc). The cable consists of a core, cladding and jacket. The core is made up of glass or fibre. Through the core the light signal is guided from the transmitter to the receiver.

From the above description of the fiber optic communications system, we can conclude that the components used in the system require only dc power supply.

Pour revenir à votre question ci-dessous ("Merci, et pour DC Fiber Cables & Optics : câbles fibre DC et équipement optique?") :
Sans contexte, je ne m'engagerai pas à décoder une abréviation interne de deux lettres comme celle-ci, qui pourrait signifier tout et n'importe quoi. Le mieux, et je dirais même souvent la seule solution, c'est de se renseigner chez le client ou d'exploiter votre texte, que nous ne connaissons pas. Voir aussi nos demandes antérieures pour en savoir plus sur le contexte !
Allez bonne fête du travail à tous - je pars me balader :-)

Ok, I had taken your comment to mean that this subject area were very new. That reassures me a bit, because I couldn't imagine that you had never dealt with it before.

La référence à la fibre optique permet d'éviter toute confusion avec d'autres domaines de l'optique, tels que les lunettes, la photographie, l'ophtalmologie ou la technologie laser.

L'optique est la branche de la physique qui traite de la lumière, de son comportement et de ses propriétés, du rayonnement électromagnétique à la vision en passant par les systèmes utilisant ou émettant de la lumière.

So what?
I don't see how vaunting your superior knowledge actually informs this question?
I've been working with fibre optics for over 30 years.
The only point I was making was that this particular usage of the EN word 'optics' seems to have been coined fairly recently — though the term 'optique' in FR has been used in similar senses for a longer time.

Thank you, interesting!

The field of fiber optics is not new, but dates back to the sixties. I became familiar with this technique about 20 years ago.

The first working fiber-optic data transmission system was demonstrated by German physicist Manfred Börner at Telefunken Research Labs in Ulm in 1965, followed by the first patent application for this technology in 1966.[21][22] In 1968, NASA used fiber optics in the television cameras that were sent to the moon.
:
The Italian research center CSELT worked with Corning to develop practical optical fiber cables, resulting in the first metropolitan fiber optic cable being deployed in Turin in 1977.[29][30] CSELT also developed an early technique for splicing optical fibers, called Springroove.[31]

'Optics' refers to all accessories necessary for connections and networks of fiber optic cables incl. their connectors. I worked with such cables, connected them to PLC inputs and outputs and programmed their interfaces, so I know the terminology in English as well.

I recently translated a couple of major RFQs in the field of F/O installations, which is the first time I encountered what I assume must be a newly-coined term for connectors, joiners, copper nterfaces, etc. etc.

So "optics" would refer to optical connectors? I've never seen "optics" used in this sense.
