A: Qhov yuav tsum tau muaj qhov sib txuas ntawm fiber ntau yog cov nram qab no:
1. Tsis tshua muaj kev twb kev txuas: poob hauv cov fiber ntau yog txuas nrog poob ntawm txoj kev txuas nrog qhov kev sib txuas kev ruaj ntseg ntawm qhov siab tshaj plaws tsis tuaj yeem ua qhov siab voltage 0.1db, thiab qhov siab tshaj plaws ntawm txoj kev txuas ntawm lub teeb connector tsis tau siab tshaj 0.2db.
Cuam tshuam cov kev txuas ntawm fiber ntau tsis muaj ntau, mas nrog rau ob txoj hauv qab no.
(1) cov qauv tsis muaj fiber ntau los ntawm qhov poob ntawm kev twb kev txuas, xws li fiber ntau me me mismatch, naj npawb aperture mismatch thiab refractive index distribution mismatch thiab lwm yam peb sib nrauj
(2) qhov kev sib txuas tsis tau los ntawm qhov sib txawv ntawm ob lub fibers, ob lub hlwv yuav tsum yog raws li lub sij hawm txuas, tab sis vim tias qhov fiber ntau heev, nws nyuaj heev rau nruj nruj. Qhov poob ntawm txoj kev sib txuas los ntawm qhov sib txawv ntawm qhov sib txawv ntawm ob lub fibers mas nws muaj xws li cov kev cuam tshuam los ntawm cov sab nraud, cov teeb meem tshwm sim los ntawm longitudinal gap, thiab cov piam sij los ntawm kev hloov ntawm qhov hloov.
2. Kev poob rov qab: poob rov qab hais txog qhov kev sib txuas ntawm fiber, tom qab lub hwj huam tawm P, qhov ntsuas ntawm cov tswv yim optical zog Pi piv ntawm tus nqi seev suab. Tib yam li tib nthwv dej (meej) qhov zoo dua, kom txo tau lub teeb pom kev zoo ntawm lub teeb thiab qhov system, tus nqi yuav tsum tsis txhob tsawg dua 45db.
3. Repeatability: hais txog qhov sib txuas rov qab, qhov poob yuav tsis yog qhov hloov tseem ceeb, cov ntsuas yuav ntsuas qhov txuas tus qauv tsim thiab kev ua haujlwm ntawm qhov kev sib txuas ntawm qhov txuas kuj yog qhov tseem ceeb ntawm qhov tswv yim, Yuav tsum tsawg tshaj 0.1 db.
4. Muaj peev xwm hloov tau
Lub fib fib fiber optic yuav tsum tau muaj peev xwm tiv thaiv cov kev hloov hauv ambient kub, noo noo thiab tshuaj yaig, thiab qee yam quab yuam sab nraud.
Raws li cov qauv ntawm lub connector, qhov sib txuas ntawm kev sib raug zoo ntawm cov khoom siv fiber ntau yog siv rau cov qauv ntawm cov khoom siv fiber ntau ntawm fiber ntau. Nws feem ntau yog ua tiav hauv qhov chaw ua haujlwm engineering. Txoj kev yog feem ntau yog kub yaj thiab txoj hlua voj. Rau qhov kub kub txoj kev yog feem ntau yog siv rau kev siv vuam tshuab hauv lub tshav pob rau thermal vuam, qhov no hom qoob loo me me, qhov nruab nrab ntawm cov pob qij txha mus rau 0.05db /, tuaj yeem yuav welded; V-groove method yog yooj yim, yooj yim rau ntau cov fiber ntau qhov txuas, Tab sis yuav tsum tau ua haujlwm tes, kev sib koom tes yog loj, 0.15db / hli.
Fiber optic connectors yog siv dav hauv cov tshuab fais fab sib txuas, cov ntaub ntawv kho qhov muag, thiab kho qhov muag ntsuas cov ntxhuav. Nws feem ntau yog siv los ua kom tiav lub teeb ci los fiber, fiber rau fiber ntau thiab fiber ntau thiab ntes, kev twb kev txuas ntawm cov khoom siv davhlau ya nyob twg. Yog ib hom kev siv qee yam uas siv qee yam siv qee yam tsis zoo, tsis muaj teeb meem dab tsi, yuav tsum muaj qhov tsis tshua qis, me me, tsis tshua muaj siab, muaj kev cia siab, yooj yim ua haujlwm, repeatability thiab interchangeability Zoo thiab pheej yig.
