Fibre Optic Technology
Fibre Optics is a technology that is used in engineering and designing a glass fibre or optical fibre which is widely use for fibre optic communications.Fibre Optic cable is one of the product of fibre optics and is constructed with a thin flexible, transparent fibre that was designed to be the wave guide to transmit data between the ends of the fibres.The advantages of using fibre optic cable:
- Fibre optic cables provides a much greater bandwidth which means that it can transmit more data than metal cables.
- Fibre optic cables are more immune than metal cables to electromagnetic interference such as radios, motors or other nearby cables.
- Fibre signals travel along with less loss than metal cables.
- Fibre Optic cables cost much less to maintain.
- Data can be transmitted digitally (the natural form for computer data) rather than analogically.
Optical Fibre Types
This type of fibre supports multiple transmission path with a larger core diameter(core size is 62.5 micrometres and cladding diameter of 125 micrometres.) mostly used for short distance communication links like within a building or inside a campus. The data rate of a typical multi mode may have a 10 Mbit/s up to 10 Gbit/s over a cable length up to 600 meters.
Multimode Fibre equipments are far less expensive than single mode fibre optic. Since multi mode fibre have a larger core size, this enables it to collect more light than single mode fibre. However, multi mode fibre gains a higher pulse spreading rate than single mode fibre, limiting its information transmission capacity.
Single Mode / Mono Mode Fibre Optic
Single Mode or Mono Mode Fibre supports a single transmission path and are mostly use over long distance communication(longer than 1,050 meters or 3,440 ft). This type of fibre have a narrower modal dispersion which enables it to retain the fidelity of each light pulse over long distances and have a higher bandwidth than multi mode fibres.
Single Mode Fibre has a core diameter between 8 – 10 micrometres, cladding diamter of 125 micrometres.
Equipments for Single Mode Fibre are much expensive but may be cheaper if get in large volume.
Special Purpose Fibre Optic is designed with a non-cylindrical core and/or cladding layer, usually with an elliptical/rectangular cross-section.
Fibre Optic Systems deliver a highly scalabe and reliable performance for high bandwidth and mission critical infrastructures. These include fibre optic cables, connectors, adapter modules, adapter panels, cassettes, enclosures, patch cords, cable assemblies, cable distribution products and accessories for both singlemode and multimode applications. It provide a complete solutions for high data rate fibre channel and ethernet applications.
Fibre Optic Splitter
A fibre optic splitter is made of an optical splitter arrangement positioned with the interior of a housing. This fibre optic splitter divides light from a single fibre into two or more fibre channels.
Fibre Optic TV
A fibre optic tv offers a high definition(HD) flawless picture quality, with an extensive programming not supported in standard a tv and high reliability. Some fibre optic tv providers are FiOS from Verizon.
Fibre Optic Modem
A fibre optic modem is used mainly for data transmission over a fibre optic network and include devices for connecting to DSL, cable, and other commercial networks.
Fibre optic modems uses a fibre optic cable for providing electrical to optical conversion of electronic communication and data signals for transmission. It receives simultaneous optical signals and converts it back to the original electronic signal which allows a full duplex transmission. Certifications and approvals for fibre optic modems include the CE Mark.
The advantages of using a fibre optic modem:
- Higher bandwidth for fast data transmission
- Lighter weight and smaller size for much quicker deployment
- Better quality and secure – no electromagnetic signature
- Less expensive

Hey, thanks for the awesome posting. I’m having troubles with subscribing to your blogs feed. Thought I’d let you know
This is so great that I had to comment. I’m usually just a lurker, taking in knowledge and nodding my head in quiet approval at the good stuff…..this required written props. Theory rocks…thanks.
