Fiber optic connector

1. Hom kis tau tus mob

Xa mus rau hom kis ntawm lub teeb nyob rau hauv optical fibers (electromagnetic teb faib daim ntawv).Feem ntau siv kev sib txuas lus fiber ntau

hom tau muab faib ua ib hom thiab multimode, nrog ib hom haum rau kev sib kis mus ntev thiab multimode haum rau

luv luv kis tau tus mob.G652D ib leeg hom optical fibers muaj ib tug tub ntxhais txoj kab uas hla d1 ntawm 9 um thiab ib tug cladding txoj kab uas hla d2 ntawm 125 um.Multimode

Optical fibers feem ntau muab faib ua ob hom: 62.5/125 lossis 50/125.

Kev xaiv ntawm optical fiber ntau yuav tsum phim qhov kho qhov muag module, txwv tsis pub nws yuav ua rau poob ntxiv vim cov tub ntxhais txoj kab uas hla tsis sib haum.

Kev sib txuas ntawm cov fibers optical thiab cables nrog cov tub ntxhais sib txawv tsis pom zoo.

2. Insertion poob

Tus nqi ntawm cov teeb liab kho qhov muag txo hwj chim, feem ntau qhia hauv decibels, thaum siv fiber ntau optic connectors rau kev sib txuas.Piv txwv li,

Thaum qhov poob qis yog 3dB, qhov hluav taws xob kho qhov muag poob yog kwv yees li 50%.Thaum qhov poob qis yog 1dB, lub zog poob yog kwv yees li

20%, thiab IL = - 10lg (tso zis optical zog / input optical zog).

3. Rov qab poob

Kuj tseem hu ua kev xav tsis zoo, nws hais txog qhov ntsuas ntawm lub teeb liab qhov kev xav tau.Echo poob piav txog tus nqi xa rov qab los ntawm tus

optical teeb liab thaum nws rov qab mus rau txoj kev qub.Feem ntau, qhov loj dua tus nqi, qhov zoo dua.Piv txwv li, thaum input 1mw zog, 10% ntawm nws yog

reflected rov qab, uas yog 10dB, thiab 0.003% yog reflected rov qab, ua rau echo poob ntawm kwv yees li 45dB.RL = - 10lg (rov qab lub teeb lub zog /

input teeb lub zog)

4. Hom ntsej muag

Optical fiber nto hom tau muab faib ua PC (spherical nto sib tsoo) thiab APC (oblique spherical nto sib tsoo).Tom qab APC sib tsoo,

lub teeb pom kev zoo rov qab los ntawm txoj kev qub yog txo qis heev, uas pab txhim kho qhov rov qab poob ntawm qhov txuas
