Ib qho khoom siv kho qhov muag muaj xws li cov khoom siv hluav taws xob photoelectronic, lub luag haujlwm ua haujlwm, thiab qhov cuam tshuam ntawm qhov muag.Lub photoelectronic tivthaiv muaj cov kis tau tus mob thiab tau txais qhov chaw.
Txhawm rau muab nws yooj yim, kev ua haujlwm ntawm optical module yog photoelectric hloov dua siab tshiab.Qhov kawg xa mus hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag, thiab qhov kawg tau txais kev hloov pauv cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob tom qab kis tau los ntawm cov fibers optical.
Ib hom yog sawv cev los ntawm SM, haum rau kev sib kis mus ntev, thaum ntau hom yog sawv cev los ntawm MM, haum rau luv luv kis tau tus mob.Qhov ua hauj lwm wavelength ntawm ib tug multi-mode optical module yog 850nm, thiab hais tias ntawm ib leeg-hom optical module. yog 1310nm thiab 1550nm.
Single-mode optical modules yog siv rau kev sib kis mus ntev, nrog rau kev sib kis deb mus txog 150 txog 200km.Multi-mode optical modules yog siv rau kev sib kis luv luv, nrog rau kev sib kis mus txog 5km.Single-mode optical modules yog siv rau kis tau tus mob ntev, nrog rau kev sib kis deb mus txog 150 txog 200km.Multi-mode optical modules yog siv rau kev sib kis luv luv, nrog rau kev sib kis mus txog 5km.
Lub teeb qhov chaw ntawm ntau hom optical module yog lub teeb-emitting diode los yog laser, thaum lub teeb qhov chaw ntawm ib hom optical module yog LD los yog LED nrog nqaim spectral kab.
Multi-mode optical modules feem ntau yog siv rau kev sib kis luv luv, xws li SR.Muaj ntau cov nodes thiab connectors nyob rau hauv hom network no.Yog li ntawd, multi-mode optical modules tuaj yeem txo cov nqi.
Tib hom optical modules feem ntau yog siv nyob rau hauv cov kab uas muaj cov kis tau tus mob siab, xws li MAN (Metropoliitan cheeb tsam network)
Tsis tas li ntawd, cov khoom siv ntau hom tuaj yeem ua haujlwm tau zoo ntawm ntau hom fibers, thaum cov khoom siv ib hom tuaj yeem ua haujlwm tau zoo ntawm ob hom ib leeg thiab ntau hom fibers.
Ib hom kev kho qhov muag ib leeg siv ob zaug ntau yam khoom raws li ntau hom optical module.Yog li ntawd, tag nrho cov nqi ntawm ib leeg-hom optical module yog ntau dua li ntawm ntau hom optical module.
Ib tug high-rate optical module yuav siv tsis tau raws li ib tug tsawg-rate optical module.Ib tug high-rate optical module yuav siv tau raws li ib tug tsawg-rate optical module.Txawm hais tias qee qhov optical modules tau sib xws nrog lwm cov khoom siv kho qhov muag, lwm tus tsis sib xws.
Lub laser emitted los ntawm ib leeg-hom optical module tuaj yeem nkag mus rau hauv fiber ntau optical, tab sis nyob rau hauv lub optical fiber ntau kis tau tus mob, qhov dispersion kuj loj, luv deb kis tau tus mob yog ok.Txawm li cas los xij, raws li lub zog kho qhov muag ntawm qhov kawg tau txais. nce, lub hwj chim kho qhov muag ntawm qhov kawg tau txais yuav overloaded.Yog li ntawd, koj raug qhia kom siv ib hom kho qhov muag fibers es tsis txhob ntawm ntau hom optical fibers rau ib hom optical modules.
Optical modules yuav tsum tau siv nyob rau hauv kev sib raug zoo hom.Piv txwv li, tus nqi kis tau tus mob, kis nrug deb, hom kis tau tus mob, thiab kev ua haujlwm wavelength ntawm cov khoom siv kho qhov muag ntawm qhov xa thiab txais qhov kawg yuav tsum yog tib yam.Interface specifications ntawm optical modules sib txawv kis tau tus mob sib txawv heev, thiab kho qhov muag modules nrog ntev kis tau tus mob nyob rau hauv tus nqi siab.Qhov kev sib cuam tshuam tuaj yeem pom tau los ntawm kev sib piv qhov tsim nyog kho qhov muag attenuation raws li lub network tiag tiag.
Thaum xa cov hluav taws xob kho qhov muag ntawm cov phooj ywg kawg yog siab tshaj qhov txwv siab ntawm qhov tau txais lub hwj chim kho qhov muag ntawm lub zos kho qhov muag module, koj yuav tsum tau txuas ib qho kev kho qhov muag attenuate lub teeb liab kho qhov muag ntawm qhov txuas, thiab tom qab ntawd txuas lub hauv paus kho qhov muag module.Long nrug. optical module Rau kev siv luv luv, siv optical attenuation, tshwj xeeb tshaj yog rau kev siv tus kheej-voj, kom tsis txhob hlawv cov optical module.
