De 980nm 1030nm 1064nm højeffekt fiberoptiske isolatorer er en fiberkoblet komponent, der tillader alt polariseret lyssignal (ikke kun lyset polariseret i en bestemt retning) at forplante sig langs en fiber i én retning, men ikke i den modsatte retning. Funktionelt er det ganske som en optisk-elektrisk diode. 980nm 1030nm 1064nm højeffekt fiberoptiske isolatorer er nødvendige i fiberoptiske systemer i mange roller, hvoraf den mest almindelige er at forhindre tilbagereflekteret lys, der kommer tilbage ned ad en fiber, i at genindtræde og forstyrre en lasers operationer. Boxoptronics giver 1W, 2W, 3W,...,10W eller andre højeffekt polarisationsvedligeholdende fiberisolatorer.
A Phase Shifted FBG Fiber Bragg Grating introduces phase discontinuities into a fiber grating, creating a narrow transmission window in the FBG's reflection spectrum. The transmission wavelength varies with the amount of phase shift. Phase-shifted FBGs can be used as demultiplexers in dense wavelength division multiplexing (DWDM) systems. The magnitude, location, and point of the phase shift have a significant impact on the performance of the demultiplexer.
The wavelength of a pump laser diode varies at different operating temperatures. The 980nm pump FBG Fiber Bragg grating wavelength lock is used to stabilize the wavelength and intensity of the optically amplified pump laser. By precisely locking the pump laser diode through feedback of a small portion of the laser signal, this type of control significantly improves the power and wavelength output accuracy and reliability of the pump laser. Specifically, it eliminates spectral mode jumps in the pump laser, reduces power intensity fluctuations caused by temperature and pump drive current variations, and greatly improves the performance of the pump laser. It is also commonly used for stabilizing distributed feedback lasers in wavelength division multiplexing systems, the optical path of tunable lasers, and fiber resonators in Raman systems. Depending on the customer's locking requirements for the pump laser, single-grating or dual-grating configurations are available. The dual-grating configuration further improves the output spectral characteristics of uncooled pump lasers.
Den manuelle variable fiberoptiske dæmper giver brugeren mulighed for manuelt at variere dæmpningen af signalet i fiberen, når det transmitteres gennem enheden. Disse VOA'er kan bruges til præcist at afbalancere signalstyrkerne i fiberkredsløb eller til at afbalancere et optisk signal ved evaluering af målesystemets dynamiske område. VOA'erne tilbydes uterminerede eller terminerede med FC/PC- eller FC/APC-stik. For andre stiktyper eller brugerdefinerede anmodninger, kontakt venligst teknisk support.
