Ang 980nm 1030nm 1064nm high power fiber optical isolator ay isang fiber-coupled component na nagbibigay-daan sa lahat ng polarized light signal (hindi lang ang light polarized sa isang partikular na direksyon) na dumami sa isang fiber sa isang direksyon ngunit hindi sa kabilang direksyon. Sa paggana, ito ay medyo tulad ng isang optic-electrical diode. Ang 980nm 1030nm 1064nm high power fiber optical isolator ay kinakailangan sa fiber optic system sa maraming tungkulin na ang pinakakaraniwan ay ang pag-iwas sa back-reflected light na bumabalik sa fiber mula sa muling pagpasok at pagkagambala sa mga operasyon ng isang laser. Nagbibigay ang Boxoptronics ng 1W,2W,3W,...,10W o iba pang high power Polarization na nagpapanatili ng fiber isolator.
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.
Ang Manual Variable Fiber Optical Attenuator ay nagbibigay-daan sa user na manu-manong ibahin ang attenuation ng signal sa fiber habang ito ay ipinapadala sa pamamagitan ng device. Ang mga VOA na ito ay maaaring gamitin upang tumpak na balansehin ang lakas ng signal sa mga fiber circuit o upang balansehin ang isang optical signal kapag sinusuri ang dynamic na hanay ng sistema ng pagsukat. Ang Manual Variable Optical Attenuator ay may single mode o PM fiber pigtails na may 900um jacket. Ang mga VOA ay inaalok nang hindi natatapos o tinapos gamit ang mga konektor ng FC/PC o FC/APC.
