Duplex fiber ntau thiab polarity
Hauv daim ntawv thov ntawm 10G Optical fiber, ob lub fibers optical siv los paub txog ob txoj kev xa cov ntaub ntawv.Ib kawg ntawm txhua qhov kho qhov muag fiber ntau txuas nrog lub transmitter thiab lwm qhov kawg yog txuas nrog lub receiver.Ob leeg yog indispensable.Peb hu lawv duplex optical fiber, los yog duplex optical fiber.
Piv txwv li, yog tias muaj duplex, muaj simplex.Simplex hais txog kev xa cov ntaub ntawv hauv ib qho kev coj.Ntawm ob qhov kawg ntawm kev sib txuas lus, ib kawg yog lub transmitter thiab lwm qhov kawg yog tus txais.Ib yam li cov faucet hauv tsev, cov ntaub ntawv ntws mus rau hauv ib qho kev taw qhia thiab tsis thim rov qab.(tau kawg, muaj kev nkag siab tsis zoo ntawm no. Qhov tseeb, kev sib txuas lus ntawm fiber ntau yog qhov nyuaj heev. Optical fiber tuaj yeem xa mus rau ob qho kev qhia. Peb tsuas yog xav pab kom nkag siab.)
Rov qab mus rau duplex fiber ntau, TX (b) yuav tsum nco ntsoov txuas nrog RX (a) txawm tias muaj pes tsawg panels, adapters lossis optical cable seem muaj nyob rau hauv lub network.Yog tias qhov sib thooj polarity tsis tau pom, cov ntaub ntawv yuav tsis raug xa mus.
Yuav kom tswj tau qhov tseeb polarity, tia-568-c tus qauv pom zoo AB polarity hla txoj kev rau duplex jumper.
MPO / MTP fiber ntau polarity
Qhov loj ntawm MPO / MTP connector zoo ib yam li SC connector, tab sis nws muaj peev xwm haum 12/24/16/32 optical fibers.Yog li ntawd, MPO tuaj yeem txuag lub txee thaiv qhov chaw zoo heev.
Peb txoj kev polarity teev nyob rau hauv TIA568 tus qauv hu ua txoj kev A, txoj kev B thiab txoj kev C feem.Txhawm rau ua kom tau raws li tus qauv TIA568, MPO / MTP qaum optical cables kuj tau muab faib ua, ua tiav kev hla thiab khub hla, uas yog, hom A (tus yuam sij nce - qhov tseem ceeb los ntawm), hom B (tus yuam sij nce - tus yuam sij nce / yuam sij down key down crossing) thiab ntaus C (key up – key down pair crossing).
Raws li pom hauv daim duab hauv qab no:
Tam sim no feem ntau siv MPO / MTP thaj cords yog 12-core fiber optic thaj qaum thiab 24-core fiber optic thaj qaum, tab sis nyob rau hauv xyoo tas los no 16-core thiab 32-core fiber optic thaj qaum tau tshwm sim.Niaj hnub no, ntau tshaj 100-core multi-core jumpers tau tawm los, thiab kev tshawb pom polarity ntawm ntau cov tub ntxhais jumpers xws li MPO / MTP ua qhov tseem ceeb heev.
