Nrog rau txoj kev loj hlob sai ntawm kev sib txuas lus kho qhov muag network, passive optical cables lossis cable systems raws li cov xov tooj tooj liab tau ncab, thiab lawv tau maj mam ua tsis tau raws li cov kev xav tau ntawm cov neeg siv thiab cov ntaub ntawv xa mus. Yog li Active Optical Cable (AOC) tau yug los hauv ib puag ncig no.
Dab tsi yog qhov active optical cable? Cov cheeb tsam ntawm daim ntawv thov yog dab tsi thiab qhov zoo yog dab tsi?
Active Optical Cables (AOC luv luv) yog optical fiber cables nruab nrog optical transceivers ntawm ob qho kawg.
Raws li lub npe qhia, cov khoom siv kho qhov muag xav tau cov khoom siv hluav taws xob sab nraud hauv cov txheej txheem kev sib txuas lus los hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag, lossis cov kab sib txuas lus uas hloov cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob. Lub optical transceivers ntawm ob qho kawg ntawm optical cable muab photoelectric hloov dua siab tshiab thiab optical kis tau tus mob. Lub ntsiab Cheebtsam tau muab faib ua ob ntu: optical path thiab circuit.
Ntawm lawv: txoj kev kho qhov muag muaj xws li lub lens thiab FA rau kev hloov lub kaum sab xis ntawm txoj kev kho qhov muag; Cov khoom siv hluav taws xob muaj xws li PCB board, substrate, VCSEL nti, VCSEL tsav nti, PD nti, thiab TIA nti.
Lub hauv paus ntsiab lus ntawm active optical cable AOC yog dab tsi?
Nyob rau ntawm ib kawg ntawm lub active optical cable, cov ntaub ntawv yog input rau hluav taws xob teeb liab, thiab hluav taws xob teeb liab yog hloov dua siab tshiab rau hauv ib tug optical teeb liab ntawm ib tug tshwj xeeb wavelength los ntawm lub photoelectric hloov dua siab tshiab ntaus ntawv. Lub teeb liab kho qhov muag yog modulated thiab ua ke thiab tom qab ntawd nkag mus rau hauv cov kab sib kis. Tom qab lub teeb liab kho qhov muag mus txog rau lwm qhov kawg, cov khoom siv hluav taws xob tshawb pom lub teeb liab kho qhov muag pom, nthuav dav thiab ua tiav, thiab tom qab ntawd cov teeb liab hluav taws xob sib txuas yog cov zis. Lub hauv paus ntsiab lus ntawm kev xa rov qab yog tib yam.
Dab tsi yog qhov zoo ntawm active optical cables?
Piv rau high-speed cables:
1 lub zog xa hluav taws xob qis ntawm qhov txuas txuas;
2 Lub ntim yog kwv yees li ib nrab ntawm cov tooj liab cables, thiab qhov hnyav tsuas yog ib feem peb ntawm cov kev kub ceev cables;
3 Nyob rau hauv lub computer chav thaiv kab hluav taws xob, cov cua ntws zoo dua thiab cov cua sov dissipation muaj zog dua;
4 Lub vojvoog khoov ntawm optical cable yog me dua li ntawm tooj liab cable;
5 Qhov kev sib kis tau ntev dua, uas tuaj yeem ncav cuag 100 txog 300 meters;
6 Qhov kev ua yuam kev me ntsis ntawm cov khoom sib kis tau zoo dua, thiab BER tuaj yeem ncav cuag 10^-15.
Piv nrog optical modules:
1 Lub optical interface ntawm lub active optical cable tsis raug, uas yog, tsis muaj teeb meem ntawm kev ntxuav thiab paug ntawm qhov muag interface;
2 Kev ruaj ntseg thiab kev ntseeg siab dua;
3 Ua kom lub network system yooj yim dua los tswj thiab tswj;
4 Txo cov nqi khiav lag luam thiab kev saib xyuas zoo thiab txhim kho kev ua haujlwm.
Cov teb twg yog cov khoom siv kho qhov muag siv rau hauv?
1 Nyob rau hauv lub chaw soj nstuam thiab cov chaw qhia ntawv, active optical cables txuas ntau lub tshuab rau tus tswv tsev, uas tsis yog tsuas yog ua kom cov ntaub ntawv ceev ceev, tab sis kuj ua kom muaj kev ruaj ntseg network.
2 Ob lub chaw cov ntaub ntawv thiab huab cua tshuab xav tau ntau dua bandwidth thiab qis zog. 10G SFP ntxiv thiab 40G QSFP ntxiv rau hauv cov khoom siv kho qhov muag tuaj yeem txuas cov khoom siv zoo (switches, routers) nrog cov chaw nres nkoj sib txuas lus ceev.
3 Digital signage kuj yog qhov chaw zoo rau cov khoom siv kho qhov muag los qhia lawv cov txuj ci, uas tuaj yeem txhawb nqa 1080p daws teeb meem hauv ib puag ncig HDMI sab nraum zoov. Tsis tas li ntawd xwb, active optical cables kuj tseem muaj txiaj ntsig zoo hauv kev sib tham ua si sab nraum zoov loj.
