“…Bu çalışmada OSA'nın sadece merkez dalga boyu okuma, tek spektrum ölçümü, otomatik ölçüm, çözünürlük değişimi, analizörü sıfırlama, spektrum bandını değiştirme ve cihaz seçimi kontrolü yapılmıştır. Akçeşme ve arkadaşları (2021) çalışmalarında ise .NET ortamında ayarlanabilir lazer kaynağını ve OSA'yı kısmi olarak kontrol etmişlerdir [20]. Arayüz tasarımında cihaz kullanımı net olarak yansıtılmamış ve komut tabanlı bir kontrol sağlanmıştır.…”

Optik spektrum analizörü (OSA), fiber optik sistemlerde verilen bir giriş sinyalinin sistem çıkışında büyüklüğünü ve gücünü frekans aralıklarına göre ölçer ve sonuçları grafiksel olarak gösterirler. Ancak OSA’lardan ölçüm alınırken manuel ölçümlerde anlık güç değişiminden dolayı ölçüm doğruluğunda hatalar oluşmaktadır. Bu nedenle ölçüm doğruluğunu sağlamak için çok sayıda ölçüm alınarak ortalama alınması doğruluğu artıracaktır. Bu çalışmada Matlab App Designer ile OSA bilgisayar üzerinden kontrol edilebilmekte ve ölçüm sonuçları istenilen şekilde çıktı olarak alınabilmektedir. Bu platform kullanılarak gerçek OSA ekranı oluşturulmuş ve uzaktan kontrol edilebilir hale getirilmiştir. Kullanıcının art arda aldığı ölçümlerin sonucu bir excel dosyasında kaydedilebilmektedir. Bu sayede kaydedilen tüm ölçümlerin ortalaması alınarak yapılan ölçümde en doğru sonuca ulaşılabilmektedir. Geliştirilen yazılımla fiber optik sistemlerde deneysel çalışmalar yapılırken kullanılan cihazların yazılımlar üzerinden erişilerek daha kolay kullanımı sağlanabilmesi ve ölçüm doğruluğunun artırılması amaçlanmaktadır.

“…Fiber optic communication systems and optical ampli ers have a great share in meeting all these requirements [2][3][4][5]. The studies carried out to date are on Erbium Doped Fiber Ampli er (EDFA) with high e ciency in the C and L bands [6][7][8][9][10]. Since the C and L bands may be insu cient, optical ampli ers that can operate effectively in the S-band have been researched.…”

The main goal of designing a multistage fiber amplifier is to achieve higher performance for long-haul optical transmission systems. In this paper, multistage triple-pass (TP) TDFAs are represented. Three types of TP-TDFA are modeled, optimized, and compared in the S-band for next-generation fiber optical communication systems. First, to examine the performance of these 3 types of TP-TDFAs, signal power, pump power, thulium-doped fiber (TDF) length, and thulium ion concentration were optimized in the input signal at the 1469 nm wavelength, which gives the highest gain value in the S-band, respectively. Second, the input signals in the 1444–1499 nm band gap were amplified by using these specified optimized values in all designs. Gain and noise figure values of all three types were obtained and analyzed by plotting separately for easy comparison. At the end of the study, all results were evaluated and all types were compared to determine the best TP-TDFA.

“…Especially in the studies in the literature on the control of fiber optic devices with software, it has been seen that a system that can conduct an experiment process has not been designed. Generally, the existence of simulation‐based studies and studies that provide only part of a single device control reveals the clarity in this area [2, 8, 32]. Additionally, it has been seen that the designs of fiber optic devices can be made close to reality, and control can be provided on the software [6].…”

In private and expensive experimental laboratory studies, there are problems such as difficulty in accessing measuring devices and materials, space and time problems, and insufficient technical support due to the need for expertise. In this study, a fiber optic laboratory (FOL), which can be used for educational and scientific research purposes, has high installation costs and has difficulty in accessing devices, was designed and realized as a remote accessible/fully controllable. All devices in the proposed laboratory have been virtualized on the MATLAB App Designer platform, and communication protocols have been defined and made remotely accessible and controllable. In the proposed system, the user accessed remotely can perform all device controls, record the measurement results, take the measurement average as much as he wants to increase the measurement accuracy, monitor the experimental setup with a camera, and receive expert support. Afterward, a sample experiment was set up on the system and the results were compared. The proposed laboratory has a high potential to establish international collaborations in remote/flexible work and scientific research. Finally, a scale was applied to FOL undergraduate, graduate, and doctoral student groups. The Cronbach α coefficient showing the reliability of the applied model was found to be .934.
