Fiberstore Updates Two New Types in DWDM System Amplifiers Category

Dec. 25th, Shenzhen, Fiberstore News – This week, Fiberstore is going to introduce a new update of product types in DWDM system amplifiers category. These two new types including Raman Fiber Amplifiers (RFA) and Inter-stage DCM supported EDFA Amplifiers will be good choice for your amplifier requirements.

Erbium-Doped Fiber Amplifier (EDFA) and Raman Amplifier are the most common type of optical amplifiers used in DWDM systems. Before launching these two new types of optical amplifiers, Fiberstore offers a wide range of DWDM System Amplifiers, such as booster amplifier, in-line amplifier and pre-amplifier. This time, we have updated two new types of the DWDM system amplifiers. They respectively are raman amplifier and inter-stage EDFA amplifier for DCM supported.

EDFAs have low noise and can amplify many wavelengths simultaneously, making EDFA amplifier be the choice for most applications in optical communications, especially in DWDM systems. As we know, in the long distance transmission, CNR distortion and CSO distortion extremely appear in the CATV system induced by dispersion. Dispersion Compensation Module (DCM) is coiled with dispersion compensating fiber to optimize the system performance. Fiberstore developed the optical amplifier special for dispersion compensation module insertion (ie. Inter-stage DCM supported EDFA amplifier), which amplify input power below DCF non-linear threshold, then enter dispersion compensating module, finally enter the second stage amplifier, and send signal to transmission fibers. It is worth noting that this Inter-stage DCM supported EDFA amplifier do not include the DCM module. It can get better performance when it is used in conjunction with our DCM modules (DC1000 Series). With our solution, signals have been actual success transmits to 600km on digital television and to 400km on digital-analog hybrid television.

Though EDFA plays an important role in DWDM system, there is still some limitation of EDFA due to its spontaneous emission (ASE) noise. As a result of numerous cascades, the accumulation of spontaneous emission noise, will greatly reduce the SNR of system receiver, thus limits the system capacity and non-relay distance. The new generation of Raman amplifier (FS-1550) achieves the amplification of the optical signal by the optical gain generated by the Stimulated Raman Scattering (SRS). Raman amplifier has a wide gain spectrum, the gain bandwidth can be further broadened by the use of multi-wavelength optical pump. After many years of research and network testing, Fiberstore develops and produces the series of FS-1550 Raman amplifier, and introduce it to the ultra-long haul optical fiber CATV transmission. Specifically in combination with the EDFA applications, the improvement of the indicators of the link is particularly evident, and get more flat gain spectra and higher optical signal to noise ratio (OSNR).
