100G CFP yog dab tsi?
CFP yog qhov kho qhov muag rau pob hluav taws xob rau cov kev tshaj lij digital kis tau xa los ntawm MSA lub koom haum, uas yog hu ua" C daim ntawv qhov tseeb pluggable" ;. CFP tau xub tsim rau 100G Ethernet systems, thiab" C" hais txog 100 hauv Latin cov lej. CFP hluav taws xob interface txhawb nqa 10 × 10Gbit / s channel xa mus rau ob qho tib si TX thiab Rx cov lus qhia, tab sis qhov khoos phis tawm tau xa tau 100G los ntawm 4 × 25Gbit / s channel zoo li 10 × 10Gbit / s channel. 100G CFP optical module tau siv dav hauv cov muab kev pab cuam xa mus, cov chaw xaib ntaub ntawv network thiab enterprise network core convergence txheej thov. Cov hom CFP qauv sib txawv yog CFP, CFP2, CFP4 thiab CFP8.
100G QSFP28 yog dab tsi?
QSFP28 optical module yog kub ntsaws module tsim rau 100G cov ntaub ntawv xa tawm, uas feem ntau siv hauv kev sib txuas lus hauv kev lag luam, tuam txhab network thiab cov chaw xa khoom. QSFP28 module sib xyaw plaub kis thiab plaub kis tau txais," Q" yog cov lus luv ntawm 4-channel (Quad)," 28" txhais tau hais tias qhov kis tus nqi ntawm txhua cov channel yog 28g. QSFP28 tuaj yeem paub 100G rau 4 × 25G ceg sib txuas lossis 100G ncaj qha sib txuas raws li qhov tshwj xeeb optical module hom. Piv txwv li, 100G QSFP28 txog 4 SFP28 DAC ceg cable tuaj yeem paub txog 4 × 25G kis, thiab QSFP28 optical module ntawm LC interface tuaj yeem siv nrog ib hom fiber ntau kom paub 100G kis. QSFP28 optical module ntawm MTP / MPO interface kuj tseem tuaj yeem ua ke nrog MTP / MPO-12 fiber ntau jumper kom paub txog 100G kis.
Daim ntawv thov ntawm CFP thiab QSFP28
Daim ntawv thov ntawm 100G CFP optical module
100G CFP optical module feem ntau yog siv hauv cov txiv neej thiab kev sib kis ntev (feem ntau tshaj li 10km).
Daim ntawv thov ntawm 100G QSFP28 optical module
Tam sim no, QSFP28 tau dhau los ua lub hnab ntim khoom tseem ceeb ntawm 100G optical module. Muaj ntau yam QSFP28 cov khoom lag luam nyob rau hauv kev ua lag luam, xws li QSFP28 DAC / AOC jumper, 100G QSFP28 SR4 / LR4 / PSM4 / CWDM4 optical module, thiab lwm yam. Cov khoom no tuaj yeem muab faib ua plaub daim ntawv thov raws li kev sib kis.
1. DAC tooj liab cable hauv khib (tsawg dua 5m)
QSFP28 DAC cable yog qhov kev daws teeb meem zoo rau kev sib txuas luv luv (tsawg dua 5m), uas tuaj yeem muab cov khoom siv hluav taws xob ua tiav thiab txo cov nqi system. Yog tias koj 100G network tso rau hauv ib qho chaw nkaum hauv 5m, koj tuaj yeem tso 100G optical module thiab ncaj qha xaiv QSFP28 DAC cable.
2. QSFP28 AOC / SR4（5-100m）
Txhawm rau kev 100G multimode optical fiber ntau ntawm cov khoom siv hluav taws xob nrog qhov deb ntawm 5-100m, koj tuaj yeem xaiv ob txoj kev: ib qho yog siv QSFP28 AOC nquag kho qhov muag cable, uas haum rau 3-20m; lwm qhov yog siv QSFP28 Sr4 optical module nrog MTP-12 OM3 / OM4 jumper, uas muaj qhov siab tshaj plaws kis mus txog 100m.
3. QSFP28 PSM4 / CWDM4 / CLR4 optical module (100m-2km)
Rau 100m-2km nrug deb kis, QSFP28 PSM4 / CWDM4 / CLR4 yog kev xaiv zoo. Koj tuaj yeem siv MTP-12 ib hom fiber ntau rau 500m lossis duplex LC ib hom fiber ntau rau 2km.
4. QSFP28 LR4 / ER4 / ZR4 transmitter
Yog tias lub network ntev 100G yuav tsum tau siv ntawm ob lub tsev (txog 10km), kev sib xyaw ntawm 100G QSFP28 LR4 optical module thiab duplex LC ib hom fiber ntau yuav tsis ploj. Yog tias qhov ncua ntev dua (40km-80km), nws raug pom zoo kom koj xaiv 100G QSFP ER4 thiab ZR4 qauv.
Xaiv 100G CFP lossis QSFP28?
Hauv cov txheej txheem ntawm kev tsim lub network, qhov twg los xaiv yuav tsum xav txog ob yam tseem ceeb: yam khoom siv kho vajtse thiab daim ntawv thov ib puag ncig. Hais txog cov ntim, CFP optical module muaj ntau dua QSFP28. Hais txog kev sib kis tau deb, QSFP28 feem ntau siv rau kev sib nrug luv (0-10km) ntawm kev hloov mus. Tau kawg, nws tsis yog txiav txim siab tias QSFP28 ER4 / ZR4 siv nrog ib hom kho qhov muag fiber ntau rau kev xa mus ntev li 40km / 80km. Txawm hais tias CFP module tseem yuav siv nyob rau hauv kev sib kis luv luv, tus txiv neej thiab kev sib kis ntev WDM kis yog qhov chaw zoo tshaj plaws rau 100G CFP.
HTF' s cov khoom lag luam zoo tau lees tias, thiab cov khoom siv siv tau yog txawv txawv.
