For gigabits and beyond gigabits transmission of data, the fibre optic communication is the ideal choice. This type of communication is used to transmit voice, video, telemetry and data over long distances and local area networks or computer networks. A fiber Optic Communication System utilizes light wave innovation to transmit the information over a fiber by changing electronic signs into light.


The optical fiber transmits light from one end of the optical fiber to the other end.


Fiber optic cables are thousands of fiber optic bundles. Compared with cables, they have many advantages. They can operate at higher data rates (bandwidth) over longer distances.


Optical fiber cables are not susceptible to electromagnetic interference (EMI), which will reduce the transmission quality of the cable.



The Origins of Fiber Optic Communication


The first transmission of an image through an optical fiber occurred in the 1930s to support early medical imaging. In the 1950s, scientists began to bundle large numbers of fiber optics (several thousand) together to transmit images. The term fiber optics was coined in the 1960s by an Indian physicist named Narinder Singh Kapany. He is commonly referred to as the father of fiber optics. Fiber optic communications began to revolutionize the telecom industry in the 1970s.

Working principle of fiber optic transmission


Not like copper wire, which is based transmission where the transmission altogether relies upon electrical flgas going through the link, the fiber optic transmission includes transmission of signs as light from one point to the next.


The constitution of fiber optic communication systems


Transceivers & TOSAs


Fiber optic transceivers are a critical piece of a fiber optic network. They are devices that contain both a transmitter and a receiver in a single package. The most common optical transmitters for fiber optic communication are semiconductor devices. These devices include LEDs (light-emitting diodes) and laser diodes. Receivers are composed of a photodetector that converts light energy into electricity (called the photoelectric effect).


One of the most important components of a transceiver is the transmitter optical sub-assembly (TOSA). A TOSA is used to convert an electrical signal into an optical signal.


Phononic & Fiber Optic Transceivers


Phononic is dedicated to supporting the needs of transceiver manufacturers by designing thermoelectric coolers (TECs), which are small semiconductor devices that efficiently cool laser diodes within TOSAs and transceivers. Effective cooling is critical to laser (and therefore, fiber optic network) performance. Phononic TECs deliver up to 60% better heat pumping density with up to 30% less power consumption in a very small form factor, allowing transceiver companies to differentiate their solutions "inside the package" where stringent industry standards don't apply.


Optical fiber transmission is widely used for data transmission, and is increasingly used to replace metal wires due to its high efficiency and high transmission capacity.


We have seen that optical cables have replaced traditional copper twisted-pair cables or coaxial cables.


With the use and demand for large bandwidth and fast speed, there is no doubt that optical fiber transmission will bring more opportunities, and will continue to be studied and expanded to meet future needs. Our enterprise network and home network benefit from the development and wide application of optical fiber.
