Yam kev paub txog ntawm bidi optical module

Bidi optical module: twv: --- bidirectional. Nws siv WDM thev naus laus zis los xa thiab tau txais qhov sib txawv nruab nrab ntawm ob lub yoj yob hauv ob qho kev qhia, yog li kom paub qhov kev sib tw kis lub zog ntawm cov cim kho qhov muag los ntawm ib lub fiber. Bidi modules yuav tsum raug siv hauv khub, thiab nws qhov txiaj ntsig loj tshaj yog txuag cov khoom siv fiber ntau. Los ntawm kev hloov cov diplexer kom phim rau qhov xav tau ntawm lub suab yoj ntawm lub transmitter thiab txais, qhov twv xa hluav taws xob cov ntaub ntawv tau txais.

Thov

Ib qho fiber ntau ob-txoj kev yog feem ntau siv rau hauv cov neeg siv cov neeg siv network kom ua tiav kev sib txuas lus ntawm cov duab, cov ntaub ntawv thiab lub suab nrog tus nqi tsawg.

1. Ib leeg fiber ntau bidi optical module yog kim dua, tab sis tsuas yog ib tus fiber ntau xav tau los txuag cov khoom siv fiber ntau, uas yog qhov kev xaiv zoo dua rau cov neeg siv cov uas tsis muaj cov khoom siv fiber ntau.

2. Lub tshuab hluav taws xob dual fiber ntau tsis tas yuav ua khub. Ob lub qauv kho qhov muag tau tuaj yeem txuas nrog. Tus nqi yog pheej yig dua li ntawm cov khoom siv fiber fiber tib leeg kho qhov muag, tab sis ib qho fiber ntau xav tau. Yog tias cov khoom siv fiber ntau txaus, dual lub fiber ntau kho qhov muag tau xaiv tau.

Txoj ntsiab cai ua haujlwm

Cov pom tseeb sib txawv ntawm bidi optical module thiab cov tsoos dual fiber bidirectional optical module yog tias bidi optical module tau nruab nrog WDM coupler, tseem hu ua diplexer, uas tuaj yeem sib cais thiab sib cais cov ntaub ntawv xa los ntawm ib leeg. Yog li no, bidi optical module tseem hu ua WDM optical module.

Txhawm rau kom ua haujlwm tau zoo, kev sib tw rau cov khoom siv hauv kev tsim kho yuav tsum tau siv hauv khub, thiab qhov ua haujlwm sib luag ntawm ob txoj kab hluav taws xob yuav tsum yog sib txuam thiab sib luag. Piv txwv li, yog tias muaj ob qho twv qhov muag siv tau siv hauv cov khub, uas yog a thiab B, qhov tau txais qhov ntev ntawm cov qauv a yog qhov kis ntawm lub ntuag ntawm module B, thiab cov kis kab ke ntawm ntu a yog txais cov kab yoj ntawm module B.

Hom ntawm bidi optical module

(1) Bidi SFP optical modules: bidi SFP optical modules feem ntau yog siv rau hauv kev ua haujlwm siab ua ke cov ntaub ntawv txuas mus los ntawm ib tus hluas fiber ntau. Yog tias qhov sib kis tau mus deb tsawg dua 40km, qhov ntev ntu cov phiaj xwm ntawm bidi SFP optical module yog 1310nm / 1550nm thiab 1310nm / 1490nm; yog tias qhov kis tau mus deb tshaj 40km, qhov ntev ntu cov phiaj xwm ntawm bidi SFP optical module yog 1550nm / 1490nm.

(2) Bidi SFP + optical module: bidi SFP + optical module yog ua kom zoo dua SFP optical module. Nws yog siv nyob rau hauv bidirectional 10g serial kho qhov muag sib txuas ntawm 1330 / 1270nm transmitter thiab 1270 / 1330nm txais, xws li IEEE 802.3ae 10gbase-bx, nrog kev sib kis ntawm 20km.

(3) Bidi x2 optical module: bidi x2 optical module siv nyob rau hauv bidirectional 10g serial optical sib txuas lus, thiab qhov module kho qhov muag no muaj ob ntu: cov ntu xa khoom siv 1330 / 1270nm DFB laser. Cov khoom txais siv kev sib xyaw ua ke 1270 / 1330nm preamplifier thiab xa xov zog.

(4) Bidi XFP optical module: bidi XFP optical module yog XFP MSA ntim kho qhov kho qhov muag nrog cov teeb tsa kuaj mob digital. Nws cov emission wavelength thiab txais wavelength yog 1330nm / 1270nm thiab 1270nm / 1330nm feem. Nws feem ntau siv nrog banded SMF, thiab qhov sib kis tau ntev tshaj plaws yuav ncav cuag 10km. Ntxiv rau, lub zog noj ntawm 2G optical module yog qis dua li ntawm 10G Optical module.

Vim li cas thiaj xaiv bidi optical module?

Qhov zoo tshaj qhov pom tseeb ntawm bidi optical module yog tias nws tuaj yeem txo ntau cov chaw nres nkoj ntawm cov iav fiber vaj huam sib luag, txuag cov nqi ntawm fiber cabling infrastructure, txo qhov chaw cabling, pab tswj fiber ntau, thiab txo tus naj npawb ntawm optical fiber xav tau. Tus nqi ntawm bidi optical module yog siab dua li ntawm cov tsoos dual fiber bidirectional optical module, tab sis tus naj npawb ntawm optical fiber yuav tsum tau ntawm bidi optical module ib chav kis tau nrug deb yog txo los ntawm ib nrab. Rau ntau lub network kab, cov nqi txuag ntawm kev siv cov khoom siv hluav taws xob tsawg dua deb tshaj tus nqi ntawm kev yuav khoom bidi optical modules.

Qhov sib txawv ntawm cov tib fiber bidirectional optical module thiab ob chav fiber bidirectional optical module:

1. WDM thev naus laus zis saws ib zaug nyob rau hauv fiber ntau bidirectional optical module, tab sis ob chav fiber bidirectional optical module tsis siv;

2. Lub fiber ntau bidirectional optical module yuav tsum tau siv hauv cov khub, thiab ob chav fiber ntau bidirectional optical module tsis xav tau;

3. Cov kev teeb tsa ntawm ib leeg fiber bidirectional optical module yog qhov nyuaj ntau dua li ntawm ob chav fiber bidirectional optical module, thiab ib qho kev sib cais yog xav tau nyob rau hauv cov qib hluav taws xob kho qhov muag;

4. Tsuas yog ib qho fiber ntau xav tau ntawm ib qho cov kab hluav taws xob bidirectional optical modules, thiab ob lub fiber fiber bidirectional optical modules xav tau;

5. Feem ntau hais lus, tus nqi ntawm ib-hom kho qhov muag module yog siab dua li ntawm ntau hom kho qhov muag module, thiab cov laj thawj yog raws li nram no:

Cov tub ntxhais txoj kab uas hla ntawm cov fiber ntau hom yog me me, tsuas yog ib hom kev kis tau tso cai, qhov kev faib tawm yog me me, thiab kev sib txuas nrog cov cuab yeej kho qhov muag yog qhov nyuaj; cov tub ntxhais qhov loj ntawm ntau hom fiber ntau loj, tso cai rau ntau pua hom kev sib kis, yog li qhov txuas nrog cov khoom siv kho qhov muag tau yooj yim, thiab qhov loj ntawm kev sib txuas ua ke tau zoo sib xws nrog multimode fiber; Ib hom kho qhov muag tau siv tau rau ntawm ob qho tib hom fiber ntau thiab multimode fiber, thaum multimode optical module tuaj yeem ua haujlwm ntawm multimode fiber.

Taw qhia ntawm cov khoos phis tawj sib txawv rau SFPs

Tam sim no, txoj kev nrawm tshaj plaws mus txog 10.3G, thiab lub ntsej muag yog LC. Nws yog tsim ntawm laser (suav nrog transmitter Tosa thiab txais Rosa), Circuit Court board IC thiab cov khoom siv sab nraud. Cov khoom siv sab nraud suav nrog lub plhaub, lub hauv paus, pcba, rub lub nplhaib, lub foob, xauv cov khawm thiab cov roj hmab ntsaws.

Kev faib tawm ntawm cov khoom siv kho qhov muag rau SFPs

Raws li tus nqi, muaj 155m / 622m / 1.25g / 2.125g / 4.25g / 8g / 10g, ntawm uas 155m thiab 1.25g yog siv dav hauv khw;

To Raws li nthwv dej wavelength: 850nm / 1310nm / 1550nm / 1490nm / 1530nm / 1610nm, qhov yoj yoj yog 850nm, nws yog ntau hom SFP, qhov sib kis tau yog tsawg dua 2km, nthwv dej yog 1310 / 1550nm, qhov sib kis yog ntau dua 2km, tus nqi ntawm peb lub nthwv dej no kuj pheej yig dua lwm yam wavelengths;

③ Raws li qhov kev ncua deb, muaj luv luv, nrug nruab nrab thiab ntev ntev;

④ Raws li kev xa cov qauv: chaw nres nkoj hluav taws xob, hom ib leeg, hom sib txuam;

Types Hom SFP tshwj xeeb suav nrog bidi-sfp, chaw nres nkoj hluav taws xob SFPs, cwdmsfp, dwdmsfp, thiab SFP + optical modules.

Qhov sib txawv ntawm SFPs thiab bidi SFPs

Raws li peb txhua tus paub, ib qho SFP cov qauv feem ntau muaj ob lub chaw nres nkoj, ib qho yog TX chaw nres nkoj rau kev xa cov cim, lwm qhov yog RX chaw nres nkoj rau txais cov cim. Txawv ntawm qhov sib txawv ntawm SFP module, bidi SFP module tsuas muaj ib qho chaw nres nkoj, uas yog lim los ntawm lim hauv qhov khoos phis tawm kho qhov muag. Kev sib xyaw ua ke WDM coupler yog siv los xa thiab txais cov cim ntawm ib leeg. Tib lub sijhawm, 1310nm optical teeb liab kis tau tus mob thiab 1550nm optical teeb liab tau txais, lossis rov qab sab nraud.
