Nzwisisa wavelengths ye850nm, 1310nm uye 1550nm mune optical fiber.
Chiedza chinotsanangurwa nehurefu hwacho, uye mufiber optic communications, chiedza chinoshandiswa chiri munharaunda ye infrared, uko kureba kwechiedza kunopfuura kwechiedza chinooneka.MuOptical fiber communication, iyo yakajairika wavelength ndeye 800 kusvika 1600nm, uye anonyanya kushandiswa wavelengths ndeye 850nm, 1310nm uye 1550nm.
Panobva mufananidzo:
Kana fluxlight ichisarudza iyo yekufambisa wavelength, inonyanya kufunga kurasikirwa kwefiber uye kupararira.Chinangwa ndechekuendesa data rakawanda nekurasikirwa kwefiber padiki kureba.Kurasikirwa kwesimba rechiratidzo panguva yekutapurirana ndiko kudzikisira.Kudzikisira kwacho kune hukama nehurefu hwesaveform, iyo yakareba iyo waveform, idiki iyo attenuation.Chiedza chinoshandiswa mufiber chine hurefu hwakareba pa850, 1310, 1550nm, saka kudzikisira kwefiber kuri kushoma, izvo zvinokonzeresa kurasikirwa kwefiber kushoma.Uye aya mawavelength matatu ane kanenge zero absorption, ayo anonyanya kukodzera kutapurirana mumafiber optical sezvinowanikwa magetsi.
Panobva mufananidzo:
Mune optical fiber kutaurirana, optical fiber inogona kukamurwa kuita imwe-modhi uye yakawanda-modhi.Iyo 850nm wavelength region inowanzo i-multi-mode optical fiber communication method, 1550nm i-single-mode, uye 1310nm ine marudzi maviri e-single-mode uye akawanda-mode.Ichitaura nezveITU-T, iyo attenuation ye1310nm inokurudzirwa kuva ≤0.4dB/km, uye kuderedzwa kwe1550nm iri ≤0.3dB/km.Uye kurasikirwa pa850nm ndeye 2.5dB/km.Kurasikirwa kweFiber kunowanzo kuderera sezvo wavelength inowedzera.Iyo yepakati wavelength ye1550 nm yakatenderedza C-bhendi (1525-1565nm) inowanzonzi zero kurasikirwa hwindo, zvinoreva kuti kudzikisira kwequartz fiber ndiyo idiki pane iyi wavelength.
Beijing Rofea Optoelectronics Co., Ltd. iri muChina "Silicon Valley" - Beijing Zhongguancun, ibhizimusi repamusoro-soro rakatsaurirwa kushandira masangano ekutsvagisa epamba nekunze, masangano ekutsvagisa, mayunivhesiti uye bhizinesi vashandi vezvesainzi.Kambani yedu inonyanya kuita mukutsvagisa yakazvimirira uye kusimudzira, dhizaini, kugadzira, kutengesa kwezvigadzirwa zveoptoelectronic, uye inopa mhinduro nyowani uye nehunyanzvi, masevhisi emunhu evaongorori vesainzi uye mainjiniya emaindasitiri.Mushure memakore ekuzvimiririra innovation, yakagadzira akapfuma uye akakwana akatevedzana ezvigadzirwa zvemafotoelectric, ayo anoshandiswa zvakanyanya mumaspala, mauto, zvekufambisa, simba remagetsi, mari, dzidzo, zvekurapa uye mamwe maindasitiri.
