Tus qauv ntawm optical module
Cov khoom sib kis yog: nkag mus rau lub teeb liab hluav taws xob nrog qhov ntsuas cov lej, tsav lub LD lossis coj los tawm qhov sib cuam tshuam tus nqi kho qhov muag teeb liab tom qab ua tiav los ntawm kev tsav tsheb sab hauv, thiab sab hauv lub zog hluav taws xob tsis zoo no feem tswj Circuit Court yog muab kom ua kom tso zis hluav taws xob teeb liab fais fab ruaj khov. Qhov txais tau yog: qee qhov nqi ntawm qee lub teeb liab hluav taws xob nkag los ntawm lub teeb kuaj pom kom pom los ntawm cov khoom siv hluav taws xob ua kom pom cov hluav taws xob. Tom qab preamplifier, sib nug xov tus nqi hluav taws xob teeb liab yog tsim tawm.
Kev faib tawm ntawm cov kho qhov muag hluav taws xob
Nws suav nrog qhov kho qhov muag txais tau kho qhov muag, qhov hloov xa khoom siv kho qhov muag, kho qhov muag hloov cov khoom sib txuas thiab kho qhov muag txuas ntxiv.
a. Lub luag haujlwm tseem ceeb ntawm optical transceiver integrated module yog kom paub meej photoelectric / electro-optic hloov dua siab tshiab, suav nrog kev tswj fais fab kho qhov muag, kev hloov kho thiab kev xa mus, cov cim taw qhia, IV hloov dua siab tshiab thiab kev txwv kev ua kom nrov dua thiab kev txiav txim siab tsim dua tshiab. Tsis tas li ntawd, nws tseem muaj cov lus nug los tiv thaiv kev tawm tsam, TX kev ua haujlwm thiab lwm lub luag haujlwm. Cov haujlwm ib txwm muaj yog: SFF, SFF +, GBIC, XFP, 1x9, thiab lwm yam.
b. Ntxiv rau qhov haujlwm photoelectric hloov dua siab tshiab, kho qhov muag xa mus ntxiv tseem ua rau ntau lub teeb liab ua haujlwm, xws li MUX / demux, CDR, kev ua haujlwm tswj, kev sib deev lub zog thiab kev saib xyuas. Cov nquag siv xa khoom xa mus ntxiv yog: 200 / 300pin, xenpak, thiab X2 / xpak.
c. Optical transceiver module, Lus Askiv lub npe transceiver, yog ib qho khoom tseem ceeb hauv kev sib txuas lus kho qhov muag fiber ntau.
Hloov tus nqi ntawm cov kho qhov muag dav
Optical module tau tsim los ntawm 155Mb / s txog 10Gb / s thaum pib, thiab tom qab ntawd qhov ceev ntawm optical module tau nce mus rau 40gmb / s thiab 100gmb / s, thiab 400gmb / s optical module tau ua tiav zoo. Nws ntseeg tau tias optical module yuav loj hlob sai dua thiab nrawm nrog qhov kev nthuav dav ntxiv hauv kev lag luam yav tom ntej.
Kev ntim khoom ntawm kho qhov muag
Tsav los ntawm kev siv thev naus laus zis, txo tus nqi thiab lwm yam, kho qhov muag ntxiv mus txuas ntxiv" kev kub ceev, miniaturization thiab kev koom ua ke" ;.
25g laser chip technology siv hauv 100g optical module. Raws li cov txheej txheem ntim sib txawv, 100g optical module feem ntau suav nrog CFP, CXP thiab qsfp28. Qsfp28 yog ib tiam tshiab ntawm 100g optical module. Ntawm 40g optical module, CFP thiab qsfp yog cov ntawv ntim tseem ceeb, thiab 40g qsfp + optical module tau siv dav. Lub ntsiab ntim cov qauv ntawm 10G Optical module suav nrog xenpak, X2, XFP, SFP, thiab SFP +, ntawm cov uas SFP + optical module yog qhov zoo tshaj plaws.
Kev sib kis deb thiab nruab nrab ntawm lub teeb nruab nrab ntawm cov kho qhov muag
Qhov kis tau tus mob deb ntawm cov kho qhov muag hluav taws xob tau muab faib ua luv luv, nruab nrab nrug thiab ntev ntev. Qhov kis tau tus mob deb ntawm cov kho qhov muag hluav taws xob tau muab faib ua luv luv, nruab nrab nrug thiab ntev ntev. Feem ntau hais lus, 2km thiab hauv qab yog luv nrug, 10-20K yog qhov nruab nrab deb, 30km, 40km thiab sab saud yog qhov kev deb.
Lub hauv nruab nrab ntu yog hais txog cov khoos phis tawm siv rau lub teeb liab kis. Tam sim no, muaj peb yam ntawm nruab nrab wavelengths ntawm optical module: 850nm, 1310nm thiab 1550nm.
850nm band: feem ntau siv rau kev sib kis luv luv ntawm ≤ 2km
1310nm thiab 1550nm waveband: nws yog feem ntau siv rau nruab nrab thiab ntev kis, thiab ntau tshaj 2km kis.
Kev ua haujlwm ntawm optical module
1. Raws li qhov khoos phis tawm kho qhov muag, nws tau txais lub teeb liab hluav taws xob thiab txuas nrog fiber ntau kho qhov muag thiab tw tw
2. Lub cim ntsuas hluav taws xob tau nkag mus rau hauv lub teeb hluav taws xob thiab ua tiav hauv lub teeb hluav taws xob
3. Vim li cas vim li cas cov khoos phis tawm kho qhov muag tau siv rau ntawm lub rooj tsavxwm kho hloov kho kom ncaj qha kho qhov kev sib txuas ntawm cov khoos phis tawm tau kho tau yog qhov khoos phis tawm tuaj yeem ua kom lub rooj sib txig kho tau kho kom haum rau ntau yam kev cuam tshuam. Thaum SC, FC, LC Tsov tus tw fiber txuas txuas, coj tus kho qhov muag coj los hloov tau tuaj yeem hloov. Ib hom ntawm
