BoxOptronics 1310nm 1550nm L-Band Polarisasi Isolator Optik bebas yaiku isolator bebas polarisasi in-line serat sing isolator Serat nglindhungi sumber cahya saka refleksi lan sinyal sing bisa nyebabake gangguan intensitas lan karusakan optik. Isolator optik, uga dikenal minangka isolator Faraday, minangka piranti magneto-optik sing luwih milih ngirimake cahya ing arah maju nalika nyerep utawa mindhah cahya sing nyebar ing arah mbalikke, Iki digunakake digunakake kanggo nglindhungi refleksi, sing bisa ngrusak sawetara pangukuran utawa ngrusak laser. lan amplifier. Isolator Optik independen 1310nm 1550nm L-Band Polarisasi iki bisa dadi siji utawa kaping pindho / tataran dobel gumantung saka tingkat isolasi optik sing dibutuhake saka cahya panyebaran.
Fiber serat formasi Fiber serat formasi serat dirancang khusus kanggo kabutuhan gabungan serat, semikonduktor bungkusan bungkus lan transmisi laser. Serat iki nduweni kerugian transmisi kurang lan kapasitas nangani daya dhuwur.
Isolator optik serat daya dhuwur 980nm 1030nm 1064nm minangka komponen gabungan serat sing ngidini kabeh sinyal cahya polarisasi (ora mung cahya polarisasi ing arah tartamtu) nyebar ing sadawane serat ing siji arah nanging ora ing arah sing ngelawan. Fungsional, cukup kaya dioda optik-listrik. The 980nm 1030nm 1064nm isolator optik serat daya dhuwur perlu ing sistem serat optik ing akeh peran sing paling umum kang Nyegah saka bali-dibayangke cahya bali mudhun serat saka ngetik maneh lan ngganggu operasi saka laser. Boxoptronics nyedhiyakake 1W, 2W, 3W, ..., 10W utawa polarisasi daya dhuwur liyane sing njaga isolator serat.
Serat transmisi energi multimod energi Murniika murni dikembangake khusus lan dirancang kanggo kabel optik transmis QBH, lan bisa ngirim laser energi kanthi dhuwur kanthi rugi.
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.
