Optical fiber transceiver yog hom Ethernet xa mus rau kev hloov pauv hloov pauv uas tuaj yeem sib pauv luv luv ntawm cov xov hluav taws xob hluav taws xob thiab lub teeb liab pom nyob deb. Nws tseem hu ua hloov fiber ntau hauv ntau qhov chaw. Cov khoom lag luam feem ntau siv nyob rau hauv cov chaw network tiag tiag qhov twg Ethernet cable tsis tuaj yeem npog thiab kho qhov muag hluav taws xob yuav tsum siv los txuas qhov chaw sib kis, thiab feem ntau nyob hauv kev nkag mus rau txheej thov kev siv dav dav tus txiv neej; piv txwv li, lub siab txhais video duab kis ntawm saib xyuas kev ruaj ntseg engineering; nyob rau tib lub sijhawm, nws tseem ua lub luag haujlwm tseem ceeb hauv kev pab txuas txuas mus deb kawg txoj kab nrug ntawm optical fiber rau tus txiv neej thiab sab nraud network.
Optical fiber transceivers feem ntau siv nyob rau hauv lub network qhov chaw ib puag ncig qhov twg Ethernet cable tsis tuaj yeem npog thiab optical fiber yuav tsum tau siv los txuas qhov kev sib kis deb. Nyob rau tib lub sijhawm ntawd, lawv tseem ua lub luag haujlwm tseem ceeb hauv kev pab txuas txuas qhov ntev km ntawm qhov kho qhov muag kab hluav taws xob rau thaj tsam thaj tsam nroog thiab sab nraud network. Nrog optical fiber transceiver, nws tseem muab cov kev daws teeb meem pheej yig rau cov neeg siv uas xav tau txhim kho qhov system los ntawm tooj liab hlau mus rau kho qhov muag thiab tsis muaj peev nyiaj, manpower lossis sijhawm. Kev ua haujlwm ntawm optical fiber transceiver yog los hloov lub teeb liab hluav taws xob peb xav kom xa mus rau lub teeb liab kho qhov muag thiab xa tawm. Nyob rau tib lub sijhawm, nws tuaj yeem hloov kho cov teeb liab tau txais rau hauv teeb liab hluav taws xob thiab muab nws rau peb qhov kawg tau txais.
Nrog rau kev tsim cov ntsiab lus siab thiab ntse tshaj tawm cov koob yees duab keb soj ntsuam, cov tseev kom muaj ntawm cov xov tooj kis teeb liab zoo, cov kwj kab thiab cov kis tau ntev tau zoo tuaj, thiab cov kab hluav taws xob tooj liab uas twb muaj lawm yog qhov nyuaj kom phim. Daim ntawv no yuav tham txog cov ntawv tshiab ntawm cov xov hlau, uas siv hluav taws xob tua hluav taws xob thiab cov kab hluav taws xob kho qhov muag, thiab siv tau hauv CCTV thiab IP network video rau kev saib xyuas.
Txheej txheem cej luam ntawm kev saib xyuas video
Tam sim no, video xyuas network tau ua ntau dua thiab nrov dua, thiab muaj ntau tus qauv los tsim cov kev soj ntsuam video, cov uas CCTV saib xyuas thiab IP lub koob yees duab xyuas yog qhov feem ntau cov qauv.
Kaw Circuit Court TV Saib Xyuas Qhov (CCTV)
Hauv cov kab ke CCTV saib xyuas ib txwm, cov koob yees duab digital koob yees duab txuas nrog (CCTV) tau txuas nrog lub tshuab khaws cia (xws li VCR lossis DVR) ntawm coaxial cable. Yog tias lub koob yees duab belongs rau PTZ lub koob yees duab (txhawb kev sib hloov tav toj, qaij thiab rub tawm), yuav tsum muaj tus tswj hwm PTZ ntxiv.
IP network video xyuas cov haujlwm
Hauv cov IP network video xyuas network, IP koob yees duab txuas nrog LAN los ntawm kev sib tw tsis sib xws (piv txwv li qeb 5, super qeb 5 thiab lwm lub network dhia) thiab hloov. Txawv sib txawv ntawm cov koob yees duab analog saum toj no, IP koob yees duab feem ntau xa thiab txais IP datagrams hauv lub network tsis xa lawv mus rau hauv cov chaw cia khoom. Tib lub sijhawm, lub yees duab ntes los ntawm IP koob yees duab tau sau cia ntawm txhua PC lossis server hauv lub network. Cov yam ntxwv loj tshaj ntawm IP network video xyuas network yog tias txhua lub koob yees duab IP muaj nws tus kheej IP chaw nyob, uas tuaj yeem nrhiav nws tus kheej hauv tag nrho cov video network. Tib lub sijhawm, vim hais tias IP chaw tus IP koob yees duab yog qhov chaw nyob, lawv tuaj yeem nkag mus thoob lub ntiaj teb.
Qhov tsim nyog ntawm cov hluav taws xob fiber ntau transceiver hauv CCTV / IP network saib video system
Ob lub vis dis aus system hais saum toj no tuaj yeem siv hauv kev lag luam lossis thaj chaw ib puag ncig network. Ntawm lawv, cov koob yees duab analog tsis zoo siv hauv CCTV feem ntau txuas nrog coaxial cable lossis unshielded twisted khub (ntau tshaj peb hom ntawm network cable), thiab IP koob yees duab feem ntau txuas nrog tsis raug khawm sib txuas (ntau dua tsib yam ntawm network cable). Vim tias ob qho ntawm ob qhov xwm txheej siv cov tooj liab cabling, qhov kev sib kis thiab lub network bandwidth tsis zoo li cov fiber ntau optical cabling. Txawm li cas los xij, nws tsis yooj yim los hloov cov tam sim no tooj liab cabling nrog optical fiber cabling, thiab muaj kev cov nyom hauv qab no:
Cov tooj liab cable feem ntau yog tsau rau ntawm phab ntsa. Yog tias siv hluav taws xob fiber ntau, yuav tsum tau xaiv cov hluav taws xob txuas hauv qhov txuas. Txawm li cas los xij, nws tsis yooj yim sua rau cov neeg siv dav dav kom ua tiav kev ua haujlwm. Cov tub txawg yuav tsum raug caw kom ua tiav kev tso, thiab tus nqi hluav taws xob tsis tsawg;
Tsis tas li ntawd, cov cuab yeej siv koob yees duab qub tsis nruab nrog optical fiber chaw nres nkoj.
Hauv kev pom txog qhov no, kev siv optical fiber transceiver thiab cov koob yees duab analog / IP lub koob yees duab nrog cov txheej txheem optical fiber tau ua rau cov neeg nyiam ua haujlwm hauv network. Ntawm lawv, optical fiber transceiver paub txog qhov txuas ntawm tooj liab cable thiab optical fiber los ntawm hloov cov hluav taws xob hluav taws xob qub mus rau lub teeb liab kho qhov muag. Nws muaj cov kev zoo hauv qab no:
Nws tsis' t yuav tsum rhais chaw los yog hloov chaw txuas ua tooj liab tooj liab. Nws tsuas yog xav kom paub meej qhov photoelectric hloov dua siab tshiab los ntawm kev cuam tshuam sib txawv ntawm cov hluav taws xob fiber transceiver, thiab txuas cov tooj liab cable thiab kho qhov muag, uas tuaj yeem txuag lub sijhawm thiab lub zog;
Txhawm rau muab tus choj ntawm tooj liab thiab xov xwm fiber ntau, uas yog hais, lub cuab yeej tuaj yeem raug siv los ua tus choj ntawm tooj liab thiab fiber vaj tse.
Feem ntau hais lus, optical fiber transceivers muab kev lag luam thiab txoj hauv kev zoo los txuas ntxiv kev sib kis ntawm lub network uas twb muaj lawm, kev pab cuam lub neej ntawm cov khoom siv hluav taws xob tsis zoo thiab kev sib kis deb ntawm ob lub network.
Yuav ua li cas siv optical fiber transceiver hauv analog / IP network video xyuas system?
Tam sim no, muaj ntau yam ntawm cov kab ke kho qhov muag fiber ntau rau hauv kev ua lag luam, xws li kev tswj hwm tsis ua hauj lwm network kho qhov muag, network tswj kev kho qhov muag fiber ntau, kev lag luam optical fiber transceivers thiab Poe optical fiber transceivers. Cov kis hluav taws xob fiber ntau no tuaj yeem paub txog kev hloov pauv ntawm photoelectric tseg, thiab Poe optical fiber transceivers tseem tuaj yeem muab lub zog rau POE cov khoom siv los ntawm network cable. Hauv qab no yog daim ntawv thov piv txwv ntawm fiber ntau qhov chaw thauj khoom thiab Poe fiber optic transceivers.
Qhov tseeb, siv fiber ntau optical siv coaxial cable thiab unshielded twisted khub tuaj yeem txhim kho cov video zoo, network bandwidth thiab kis deb ntawm kev saib xyuas video. Kev siv cov duab hluav taws xob optical transceiver hauv CCTV / IP network video saib xyuas lub tshuab tuaj yeem ua kom pom cov duab zoo thiab ntev txuas ntawm kis ntawm lub teeb liab, uas yuav txuag tau ntau tus neeg, lub sijhawm thiab tus nqi nce qib network.
