Nzwisisa marefu e850nm, 1310nm uye 1550nm mu fiber ye optical
Chiedza chinotsanangurwa nehukuru hwacho hwemafungu, uye mukutaurirana kwefiber optic, chiedza chinoshandiswa chiri munzvimbo ye infrared, uko hurefu hwemafungu echiedza hwakakura kupfuura hwechiedza chinoonekwa. Mukutaurirana kwefiber optic, hurefu hwemafungu hunowanzova 800 kusvika 1600nm, uye hurefu hwemafungu hunonyanya kushandiswa ndi 850nm, 1310nm uye 1550nm.
Mufananidzo wakabva:
Kana fluxlight ikasarudza wavelength yekutumira, inonyanya kufunga nezvekurasikirwa kwefiber uye kupararira kwayo. Chinangwa ndechekutumira data rakawanda nekurasikirwa kushoma kwefiber padaro refu. Kurasikirwa kwesimba rechiratidzo panguva yekutumira ndiko kuderedzwa kwesimba. Kuderedzwa kwacho kwakabatana nehurefu hwewaveform, waveform yakareba, kuderedzwa kudiki. Chiedza chinoshandiswa mufiber chine wavelength yakareba pa850, 1310, 1550nm, saka kuderedzwa kwefiber kushoma, izvo zvinogumawo nekurasikirwa kushoma kwefiber. Uye ma wavelength matatu aya haana kunyudzwa zvakanyanya, ayo anonyanya kukodzera kutapurirwa mu optical fibers senzvimbo dzechiedza dziripo.
Mufananidzo wakabva:
Mukutaurirana kwefiber ye optical, fiber ye optical inogona kukamurwa kuita single-mode uye multi-mode. Dunhu re 850nm wavelength rinowanzova nzira yekutaurirana yefiber ye optical ye multi-mode, 1550nm i single-mode, uye 1310nm ine mhando mbiri dze single-mode ne multi-mode. Tichitaura nezve ITU-T, attenuation ye 1310nm inokurudzirwa kuva ≤0.4dB/km, uye attenuation ye 1550nm i ≤0.3dB/km. Uye kurasikirwa pa 850nm i 2.5dB/km. Kurasikirwa kwefiber kunowanzo derera sezvo wavelength ichiwedzera. Wavelength yepakati ye 1550 nm yakakomberedza C-band (1525-1565nm) inowanzonzi zero loss window, zvinoreva kuti attenuation ye quartz fiber ndiyo diki pane iyi wavelength.
Beijing Rofea Optoelectronics Co., Ltd. iri mu "Silicon Valley" yeChina - Beijing Zhongguancun, ikambani yetekinoroji yepamusoro yakatsaurirwa kushandira masangano ekutsvagisa emuno nekunze kwenyika, masangano ekutsvagisa, mayunivhesiti nevashandi vekutsvagisa sainzi vemabhizinesi. Kambani yedu inonyanya kuita tsvakurudzo yakazvimirira nekugadzira, dhizaini, kugadzira, kutengesa zvigadzirwa zve optoelectronic, uye inopa mhinduro itsva uye masevhisi ehunyanzvi, akagadzirirwa vaongorori vesainzi nemainjiniya emaindasitiri. Mushure memakore ekuvandudza kwakazvimirira, yakagadzira nhevedzano yakapfuma uye yakakwana yezvigadzirwa zve photoelectric, izvo zvinoshandiswa zvakanyanya mumaindasitiri emaguta, emauto, ekufambisa, emagetsi, emari, dzidzo, ekurapa nedzimwe nzvimbo.
