Iyo fiber pigtail inoreva chinongedzo chakafanana nehafu jumper inoshandiswa kubatanidza optical fiber uye optical fiber coupler.Inosanganisira jumper connector uye chikamu che optical fiber.Kana kubatanidza michina yekufambisa uye ODF racks, nezvimwe.
Mugumo mumwe chete weiyo optical fiber pigtail ndeye inofambiswa yekubatanidza.Mhando yekubatanidza ndeye LC/UPC, SC/UPC, FC/UPC, ST/UPC, LC/APC, SC/APC, FC/APC.Magumo ese ari maviri ejumper majoini anotakurika.Kune akawanda marudzi emainterface, uye akasiyana mainterface anoda akasiyana macouples.Iyo jumper yakakamurwa kuita maviri uye inogona zvakare kushandiswa sepigtail.
Iyo yepakati dhayamita ye multimode fiber ndeye 50-62.5μm, iyo yekunze dhayamita yecladding ndeye 125μm, iyo dhayamita yeiyo single-mode fiber ndeye 8.3μm, uye dhayamita rekunze rekuvhara 125μm.Iyo yekushanda yavelength yeoptical fiber ine pfupi wavelength 0.85μm, kureba wavelength 1.31μm uye 1.55μm.Fiber kurasikirwa kunowanzodzikira nekurebesa kwewavelength.Kurasikirwa kwe0.85μm ndeye 2.5dB / km, kurasikirwa kwe1.31μm ndeye 0.35dB / km, uye kurasikirwa kwe1.55μm ndeye 0.20dB / km.Uku ndiko kurasikirwa kwakaderera kwefiber, ine wavelength ye1.65 Kurasikirwa pamusoro pe μm kunowedzera kuwedzera.Nekuda kwekutorwa kweOHˉ, kune kurasikirwa kwepamusoro muzvikamu zve 0.90 ~ 1.30μm uye 1.34 ~ 1.52μm, uye aya maviri mazinga haashandiswe zvizere.Kubva ku1980s, single-mode fibers yave ichishandiswa kakawanda, uye yakareba-wavelength 1.31μm yakashandiswa kutanga.
Multimode fiber
Multi Mode Fiber:Iyo yepakati girazi musimboti wakakora (50 kana 62.5μm), iyo inogona kufambisa akawanda modes echiedza.Nekudaro, iyo inter-mode dispersion yakakura, iyo inodzikamisa kuwanda kwekufambiswa kwemasaini edhijitari, uye inova yakakomba nekuwedzera kwechinhambwe.Semuenzaniso: 600MB/KM optical fiber ine chete 300MB bandwidth pa2KM.Naizvozvo, kureba kwekufambisa kwemultimode fiber ipfupi, kazhinji makiromita mashoma.
Single Mode Fiber
Single Mode Fiber:Iyo yepakati girazi musimboti yakatetepa kwazvo (iyo yepakati dhayamita inowanzo 9 kana 10 μm) uye inogona chete kufambisa imwe nzira yechiedza.Naizvozvo, kupararira kwayo kwepakati-modhi idiki kwazvo, iyo inokodzera kutaurirana kure-kure, asi kune zvinhu kupararira uye waveguide dispersion.Nenzira iyi, single-mode fibers ine zvidikanwi zvepamusoro zvehupamhi hwe spectral uye kugadzikana kwechiedza chechiedza, kureva kuti, hupamhi hwehupenzi hunofanira kuva hwakamanikana uye hwakagadzikana.Zvirinani.Gare gare, zvakazoonekwa kuti pakureba kwe1.31μm, kupararira kwezvinhu uye waveguide dispersion ye-single-mode fiber yakanaka uye yakaipa, uye hukuru hwakafanana.Izvi zvinoreva kuti pawavelength ye1.31μm, kupararira kwese kwe-single-mode fiber ndeye zero.Kubva pakuona kwekurasikirwa kwemaitiro efiber optical, 1.31μm inongova hwindo rakaderera rekurasikirwa kwefiber optical.Neiyi nzira, iyo 1.31μm wavelength dunhu rave rakanyatsoshanda hwindo re optical fiber kutaurirana, uye zvakare ndiro guru rekushanda bhendi rezvino rinoshanda optical fiber communication system.Iwo makuru ma paramita e1.31μm akajairwa single-mode fiber anotemerwa neInternational Telecommunication Union ITU-T mukurudziro yeG652, saka fiber iyi inonzi zvakare G652 fiber.
Single-mode fiber, iyo dhayamita yepakati idiki kwazvo (8-10μm), chiratidzo chemaziso chinongofambiswa pane imwe chete inogadziriswa angle nefiber axis, uye inongotapurirwa mune imwechete modhi, inodzivirira kupararira kwemodal uye inoita imba yekutapurirana. bandwidth yakafara.Kutapurirana simba kwakakura, kurasikirwa kwechiratidzo chekuona kuduku, uye kupararira kuduku, iyo inokodzera hukuru-hukuru uye kureba kwekutaurirana.
Multi-mode fiber, chiratidzo che optical uye fiber axis inotapurirwa pamakona akawanda anogadziriswa, uye ma-multi-light transmission anoparadzirwa nenzira dzakawanda panguva imwe chete.Iyo dhayamita ndeye 50-200μm, iyo yakaderera kune kutapurirana kuita kwe single-mode fiber.Inogona kukamurwa kuita multimode abrupt fiber uye multimode graded fiber.Iyo yekutanga ine yakakura musimboti, akawanda ekufambisa modhi, nhete bandwidth, uye diki yekutapurirana simba.
RAISEFIBER inoshanda mukugadzira tambo dze optical patch uye pigtails, uye inopa nyanzvi fiber optic zvigadzirwa kune vatengi vane yakasanganiswa wiring.
