I had never imagined that Optical Fibre Cables (OFC) would play such an important role in the installation of the Mark VI network at the Siddhirganj Project. The problem was noticed at the time of initial installation of HMIs. We had to connect 3 separate HMIs and 2 separate panels which were installed inside 3 separate buildings into the same network. Because of the distance among the buldings normal UTP cable could not be used. So the only solution was using OFC. I was excited but at the same time a little tense as I had never seen OFC connection before and I had no idea how it was to be done. However some googling and consultation with the executing agency made the scheme almost clear to me. As I understood it was going to be somewhat like this -
Network Switch - Ethernet Patch cord - Media Converter - OF Patch cord - LIU - OFC - LIU - OF Patch cord - Media Converter - Ethernet Patch cord - Network Switch
Where Media Converter converts light to electrical signal (in our case ethernet) and vice versa, and LIU is like a Junction Box for fibre interconnection which uses Pigtail connectors.
From further study of the supplied hardware, it was found that the Media Converters would not be required as the Allied Telesyn AT-8624T/2M network switches were having in-built AT-A45/SC OFC connection ports which were nothing but media converters with SC (among so many types of OFC connectors it is the square push-type one) connector. Such a great product! The rest was easy -
Network Switch - OF Patch cord - LIU - OFC - LIU - OF Patch cord - Network Switch
Though the scheme looked pretty easy, the job was not. Optical Fibre cable connection is hell of a job, consisting of so many steps in which Splicing is the toughest and not a child's play. But we were through.
Next was the testing. We were smart enough to jump over the light test. We went for the much easier method. Yes, ping-ing! Since IPs were known, it took only a few minutes to know that our communication was established.

Optical fibre cables is faster and more accurate way of sending data from one point to another. This fibre cables are used by more and more companies in sending data as compared to traditional metal cables for new installations. Multi-core fibre cabling contain more than thousands of separate cores that allows thousand separate lines of communication to transfer in whatever form necessary.
