Raws li peb txhua tus paub, optical module yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv cov khoom siv kho qhov muag. Optical module yog photoelectric module rau photoelectric thiab electro-optical conversion, uas plays lub luag hauj lwm ntawm photoelectric teeb liab hloov dua siab tshiab. Nrog rau txoj kev loj hlob sai ntawm kev lag luam network, qhov kho qhov muag module kuj tau hloov zuj zus. Tam sim no compact optical modules, uas feem ntau yog cov pob me me, tau nthuav dav thiab txais tos los ntawm pej xeem.
Compact optical module yog dab tsi?
Compact optical module yog qhov kub-plug me me pob module ntim los ntawm SFP. Nws lub luag haujlwm tseem ceeb yog hloov cov teeb liab hluav taws xob ntawm qhov kawg xa mus rau lub teeb liab optical thiab xa tawm. Tom qab tau txais cov ntaub ntawv, lub teeb liab kho qhov muag tau rov qab los rau lub teeb liab hluav taws xob ntawm qhov kawg tau txais. Compact optical module yog tsim los ntawm laser (xws li transmitter TOSA thiab receiver ROSA), circuit board IC thiab lwm yam accessories, uas muaj xws li lub plhaub, puag, PCBA, nplhaib, clasp, xauv daim thiab roj hmab ntsaws.
Dab tsi yog cov hom ntawm compact optical modules?
(1) Raws li tus nqi ntawm kev faib tawm: 155M / 622M / 1.25 G / 2.125 G / 4.25G / 8 G / 10G. 155M thiab 1.25G tau siv ntau dua hauv khw.
(2) Raws li kev faib tawm ntawm wavelength: 850nm / 1310nm / 1550nm / 1490nm / 1530nm / 1610nm. Wavelength ntawm 850nm yog multimode; nrog rau kev sib kis deb li ntawm 2 km. 1310/1550nm wavelength yog rau ib hom, kis tau tus mob deb tshaj 2km.
(3) Raws li kev faib tawm kev ncua deb: luv luv, nruab nrab nrug, nyob deb.
(4) Raws li hom kis tau tus mob: hluav taws xob interface, ib hom, multimode.
(5) Cov khoom tshwj xeeb ntawm cov khoom siv kho qhov muag kuj suav nrog: BIDI-SFP, hluav taws xob interface SFP, CWDM SFP, DWDM SFP, SFP + optical module thiab lwm yam.
Cov qauv thiab lub hauv paus ntsiab lus ntawm compact optical module
Compact optical module yog tsim los ntawm TOSA module, ROSA module thiab PCBA board raws li kev faib khoom kho vajtse. Hauv qab no yog cov qauv thiab cov qauv ntawm optical module.
1. Optical emission module TOSA. Optical emission module yog qhov tseem ceeb ntawm optical emission module, nyob rau hauv uas lub teeb qhov chaw laser diode yog cov tub ntxhais.
2. Tau txais kev tivthaiv ROSA, kev ua haujlwm ntawm cov khoom siv tau txais yog los hloov cov teeb liab tsis muaj zog kho qhov muag tom qab kis mus rau hauv cov teeb liab hluav taws xob, thiab ua kom nrov nrov thiab kho qhov qub input hluav taws xob teeb liab. Cov khoom tau txais, ROSA, yog tsim los ntawm cov duab ntes thiab lub hauv ntej (Trans resistive) amplifier thiab lwm yam khoom nyob rau hauv cov qauv nruj. Feem ntau siv ROSA yog PIN-TIA thiab APD-TIA.
3. PCBA pawg thawj coj saib. PCBA yog tsim los ntawm optical emission circuit thiab txais Circuit Court.
Cov khoom siv kho qhov muag puas tuaj yeem siv rau hauv SFP + qhov?
Compact optical modules tuaj yeem khiav hauv SFP + slots, tab sis SFP + optical modules tsis tuaj yeem khiav hauv cov teeb pom kev zoo. SFP + cov chaw nres nkoj feem ntau tsis txhawb kev nrawm dua 1G. Hauv lwm lo lus, peb tsis tuaj yeem ntxig 100BASE SFP optical module ntawm SFP + chaw nres nkoj. Qhov tseeb, rau qhov teeb meem no, nws nyob ntawm ntau yam ntawm tus qauv hloov.
Txawm li cas los xij, SFP + optical modules tsis tuaj yeem siv tau rau 1G los txhawb SFP optical modules. Tsis zoo li tooj liab SFP muaj nyob rau hauv 10/100/1000 tsis siv neeg compatibility, optical fibers xws li SFP thiab SFP + tsis txhawb tsis siv neeg compatibility. Txawm hais tias nws muaj peev xwm siv lub compact optical module ntawm SFP + chaw nres nkoj hauv ntau qhov xwm txheej, qhov no tsis tau txhais hais tias nws nkag mus rau hauv SFP + chaw nres nkoj tau txais kev txhawb nqa 1G. Hauv qhov txuas fiber ntau optic, nws yuav tsis ua haujlwm yog tias peb ntxig cov khoom siv kho qhov muag ntawm ib qho SFP + chaw nres nkoj (1G) thiab tom qab ntawd ntawm lwm qhov SFP + chaw nres nkoj (10G).
Thaum siv compact optical modules thiab SFP + optical modules hauv ib lub network, nco ntsoov tias ob qhov kawg ntawm qhov txuas fiber ntau muaj qhov ceev tib yam. Lub compact kho qhov muag module tuaj yeem siv rau hauv SFP + chaw nres nkoj, tab sis lub compact optical module tsis tuaj yeem txuas nrog SFP + optical module.
Compact optical module thiab SFP + DAC high-speed cable sib txawv
(1) Compact optical module txhawb ntau yam kev cai thiab kev siv, xws li 100M Ethernet thiab gigabit Ethernet (GBE), fiber ntau channel (FC), dual channel thiab bidirectional kis ntawm synchronous fiber network (SONET). Qhov nruab nrab ntawm cov khoom siv kho qhov muag yog ib hom fiber ntau (SMF), ntau hom fiber ntau (MMF) thiab tooj liab cable. Ntawm lawv, ntau hom fiber ntau tuaj yeem txhawb nqa 1000base-sx chaw nres nkoj hom hauv daim ntawv thov ntawm 1GbE.
(2) Kev kub ceev SFP + DAC cable yog ib qho passive twin-spindle cable sib dhos, thiab txuas ncaj qha rau SFP + module. SFP + direct kev twb kev txuas muaj ib tug taag ntev cable, feem ntau yog 3, 5 los yog 7 meters nyob rau hauv ntev, siv me me cables thiab me me SFP + optical module, nrog rau qhov zoo ntawm lub hwj chim tsawg, tsis muaj nqi thiab tsis muaj ncua sij hawm. Lub architecture ntawm TOR hloov tau dhau los ua ib qho ntawm cov lus qhia hauv virtualizing cov chaw zov me nyuam. Raws li tus neeg rau zaub mov ceev ntawm txhua lub txee nce, tus naj npawb ntawm kev sib tshuam ntawm tus neeg rau zaub mov thiab kev nkag mus tau nce, qhov kev ncua deb yog luv, thiab kev ncua tau txo qis heev. Lub sijhawm no, qhov kom zoo dua ntawm tus nqi qis thiab kev siv hluav taws xob ntawm 10G SFP + DAC hom kev sib txuas ncaj qha tuaj yeem cuam tshuam zoo tshaj plaws.
Qhov sib txawv ntawm compact optical module thiab GBIC optical module, SFP + optical module
(1) Compact optical module yog los daws qhov teeb meem ntawm GBIC optical module ntim loj heev, nws txoj haujlwm thiab GBIC kho qhov muag module zoo ib yam, qhov ntim tsuas yog ib nrab ntawm qhov kawg, tsim nyog rau cov kab hluav taws xob siab. Tsis tas li ntawd, lub compact optical module siv LC interface (GBIC optical module USES SC interface), uas yuav tsum tau siv ua ke nrog LC optical fiber jumper. Nws kis tau tus nqi sib txawv ntawm 100Mbps mus rau 4Gbps, thiab kis tau tus mob mus txog ntau pua kilometers.
(2) Compact optical module yog tib yam ntawm SFP + optical module, SFP + optical module yog hloov kho dua tshiab ntawm cov qauv kho qhov muag, thiab lawv qhov sib txawv tseem ceeb yog qhov ceev.
Nco ntsoov siv cov compact optical module thiab SFP + DAC high-speed cable
Cov ntawv sau rau kev siv compact optical module
(1) Thaum siv cov khoom siv kho qhov muag, tsis txhob kov cov hlau txuas ib feem ntawm cov khoom siv kho qhov muag, kom tsis txhob ua rau cov khoom siv kho qhov muag puas.
(2) Thaum ntxig compact optical module, paub meej tias lub compact optical module yog txuas mus rau tus kov ntawm lub compact optical module electro-optical chaw nres nkoj thiab ces ntxig.
(3) Yog hais tias tsuas yog tawm ntawm lub compact optical module, tsis txhob unplug lub teeb lub qhov ncauj plua plav plug, ncaj qha tso.
(4) Thaum rub tawm lub compact optical module, ua ntej rub tawm cov kab fiber ntau, rub tus kov mus rau txoj hauj lwm ntawm 90 degrees thiab maj mam rub tawm, rub tawm thaum rub tawm tsis tuaj yeem nyuaj dhau los yog rub tawm tus kov tsis nyob hauv qhov chaw, tej zaum yuav ua rau kev puas tsuaj rau lub compact optical module shield.
SFP + DAC high-speed cable siv daim ntawv
(1) Thaum ntxig SFP + DAC high-ceev cable, koj yuav tsum thawb lub SFP + cable module raws kab rov tav kev taw qhia maj mam mus rau hauv lub qhov, kom txog rau thaum kev sib cuag nrog lub qhov.
(2) Thaum tshem tawm SFP + DAC high-speed cable, rub lub nplhaib rub tawm sab nraud raws kab rov tav kev taw qhia kom lub cable module qhib, thiab rub tawm lub cable, tib lub sijhawm nrog tes tawm tsam SFP + module hlau plhaub.
(3) Tsis txhob khoov ntau dhau, twist lub cable hauv cov txheej txheem ntawm kev ntxig, txwv tsis pub nws yuav ua rau muaj kev puas tsuaj mus tas li.
(4) Tsis txhob cia tus Tsov tus tw fiber yog nyob ntawm koj ob lub qhov muag. Tsis txhob saib rau hauv fiber ntau. Tsis txhob pom cov fiber ntau ncaj qha los yog siv cov cuab yeej siv, laser tsis pom, tab sis yuav ua rau tib neeg lub qhov muag puas.
