Abstract:

Fiber optic communication technology is becoming increasingly important in various fields, and high-speed, large-capacity fiber optic transmission systems are urgently needed. The design of fiber amplifiers is influenced by both fiber length and doping concentration. Although the Erbium-doped fiber amplifier (EDFA) is one of the most widely used components in fiber optic communication systems, its working area cannot meet the growing demand for network traffic.This paper presents a new fiber amplifier operating in the spectral region of 1700-1800 nm, pumped by commercially available laser diod

Abstract:

Nowadays, in fiber optic communications the growing demand in terms of transmission capacity has been fulfilling the entire spectral band of the erbium-doped fiber amplifiers (EDFAs). This dramatic increase in bandwidth rules out the use of EDFAs, leaving fiber Raman amplifiers (FRAs) as the key devices for future amplification requirements. On the other hand, in the field of high-power fiber lasers, a very attractive option is provided by fiber Raman lasers (FRLs), due to their high output power, high efficiency and broad gain bandwidth, covering almost the entire near-infrared region.

Abstract With the continuous evolution of communication technology, and the rapid rise of fiber optic communication in China However, the transmission distance of fiber optic communication is limited due to its fiber loss, so fiber optic amplifier has become one of the key research topics today. Currently on the market is a large-scale commercial bait-doped fiber amplifier, although it has the advantage of low noise and high gain, its effective amplification band is only concentrated in 1530 nm-1620 nm, however, there are many important transmission band amplification there are still research

High gain, wide bandwidth, low noise, and low-power transimpedance amplifiers based on new BiCMOS common- base topologies have been designed for fiber-optic receivers. In particular a design approach, hereafter called "A more- FET approach", added a new dimension to effectively optimize performance tradeoffs inherent in such circuits. Using conventional silicon 0.8 μm process parameters, simulated performance features of a total-FET transimpedance amplifier operating at 7.2 GHz, which is close to the technology fT of 12 GHz, are presented.

Abstract:

Lots of research efforts have been devoted to increase the transmission capacity in optical communications using orbital angular momentum (OAM) multiplexing. To enable long-haul OAM mode transmission, an in-line OAM fiber amplifier is desired. A ring-core fiber (RCF) is considered to be a preferable design for stable OAM mode propagation in the fiber. Here, we demonstrate an OAM fiber amplifier based on a fabricated ring-core erbium-doped fiber (RC-EDF). We characterize the performance of the RC-EDF-assisted OAM fiber amplifier and demonstrate its use in OAM multiplexing communications with OA

Abstract:

The ever-increasing demands for the use of fiber-optic sensors powered by long optical fibers is forcing developers to solve problems associated with powering these remote sensors. Due to their non-electric character, these sensors are suitable for many uses, including military applications. The Army of the Czech Republic is very interested in this type of optical fiber sensor as it fulfils the significant prerequisites for use in military areas. However, the army’s requirements are challenging because they require long supply cables in which there is significant attenuation of optical power.

So, to make, cheap and meaningful communication through optical fiber it must be required to calculate how and what amount of signal is transmitted with the given length of the fiber. Finally, it is said that the optical fiber network have several limitations like extension ratio. So, it is necessary to investigate its affect on the performance of the Optical Network.

Abstract:

The electromagnetic interference (EMI) around the devices for ionizing radiation experiments is a serious concern. In order to reduce EMI and enhance the signal-to-noise ratio, a new type of analog fiber optic link (FOL) has been developed for fast pulse signal transmission under complicated electromagnetic fields. Electrical signals are converted to optical signals through an electro-optical conversion process using the amplitude modulation mechanism. After long-distance transmission, optical signals can also be restored via photoelectric conversion. Each link has a transmitter unit connected

Although free space optical (FSO) communication has a variety of advantages, such as license free, high bandwidth, and high security, its link distance is limited by weather conditions.

The use of optical amplifiers not only improve signal to noise ratio (SNR), but also increase the link distance of the FSO system. In this paper, the erbium-doped fiber (EDFA)'s length and location were optimized to improve the FSO transmission range. The optimization
