Hauv kev sib txuas lus kho qhov muag, duplex thiab cov kab ke sib txuas kho qhov muag tau yog ob qho ntawm feem ntau siv cov kab tsheb cabling. Cov ncej no yuav tham txog qee cov kev sib txuas tshwj xeeb uas siv 2-fiber duplex thiab 8-fiber / 20-fiber parallel parallel fiber optic modules.
Ib txoj kab txuas ntxiv tau ua tiav los ntawm kev siv ob lub fibers. Feem ntau siv txuas txuas yog du LC. TIA tus qauv txhais ob hom duplex fiber ntau cov hlua txuas nrog kev ua tiav duplex LC txuas kom ua tiav qhov kawg-rau-kawg fiber ntau qhov txuas txuas: A-rau-A thaj cable (tus ntoo khaub lig version) thiab A-rau-B thaj cable (a ncaj version). Hauv tsab xov xwm no LC rau LC duplex cables uas peb siv yog txhua tus A-rau-B thaj cables. Nws txhais tau tias lub teeb liab kis no yuav kis tau ntawm B txuas thiab tau txais ntawm A txuas.
Daim duab 1: ob hom fiber ntau thaj cables
Qhov txuas txuas tau ua tiav los ntawm kev sib txuas ntawm ob qho lossis ntau txoj kab ke. Cov kab ke txuas rau qhov muag muaj peev xwm ua tiav los ntawm kev siv 8 lub xov tooj (4 daim txiag rau Tx thiab 4 daim txiag rau Rx), nees nkaum fibers (10 kab rau Tx thiab 10 daim txiag rau Rx) lossis nees nkaum plaub fiber ntau (12 fibers rau Tx thiab 12 fibers rau Rx )). Txhawm rau ua tiav 8-fiber kho qhov muag txuas, tus qauv cabling yog 12-fiber lub pob tw nrog MTP txuas (12-fiber txuas). Nws ua raws li hom B polarity tswvyim. Cov hom sib txuas thiab ua ke ntawm cov kab nrig tau qhia nyob hauv daim duab 2.
Daim duab 2: parallel fiber (8-fiber) optic kis
Txhawm rau kom ua tiav 20-kab hluav taws xob qhov sib txuas ntawm qhov kho qhov muag, ib txoj kab txuas 24-fiber MTP txuas. Nws cov fiber ntau haum thiab hom txuas yog qhia hauv daim duab 3.
Peb yuav sib tham txog cov khoom uas yuav tsum muaj los txuas ob lub roj av hloov hluav taws xob hauv ntu no. Cov 2-fiber ntau ua ke muaj xws li tab sis tsis tas rau: 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 40GBASE-BiDi, 40GBASE-LR4, 40GBASE-LRL4, 40GBASE-UNIV, 40GBASE-FR, 100GBASE-LR4, 100GBASE- ER4, 100GBASE-CWDM4, 100GBASE-BiDi, 1GFC, 2GFC, 4GFC, 8GFC, 16GFC, 32GFC.
Thaum sib txuas ncaj qha ob lub duplex SFP + transceivers, yuav tsum muaj A-rau-B thaj thaj cable. Hom kev sib txuas ncaj qha tau pom zoo kom tsuas yog siv tsis pub dhau ib kab ntawm cov racks / txee. Daim duab 4 qhia ob qho SFP + s sib txuas los ntawm ib lub LC rau LC duplex patch cable.
Daim duab 4: 2-fiber rau 2-fiber ncaj qha mus txuas
Daim duab hauv qab no yog kev sib tshuam rau ob lub duplex transceivers. Ib qho 8-fiber MTP lub cev pob zeb tau muab xa nrog 8-fiber MTP-LC breakout module txuas nrog qhov kawg ntawm pob tw. Nws yuav tsum raug sau tseg tias qhov polarity tau raug tswj xyuas thaum lub sijhawm sib kis. Thiab cov pinned txuas rau yuav tsum tau muab siv nrog cov twj tsis muaj neeg. Cov txheej txheem cabling pub rau kev txav mus tau yooj yim, ntxiv thiab hloov pauv (MACs). Daim duab 5 qhia txog qhov kev daws qhov teeb meem no.

Daim duab 6 kuj tseem yog kev sib txuas lus rau SFP + transceivers, tab sis sab xis yog 8-fiber MTP mus rau 4 x LC harness cable thiab MTP adapter vaj huam sib luag tau siv hloov chaw. Txoj kev daws teeb meem no ua haujlwm zoo tshaj plaws thaum kev sib txuas tau rau qhov chaw nres nkoj siab hloov pauv.

Txoj kev hais haum no yog duplex sib txuas. Nws yuav tso cai rau tag nrho cov patching yuav tau ua nyob rau ntawm qhov chaw faib loj (MDA) nrog qhov siab tshaj plaws rau kev sib txuas ntawm chaw nres nkoj-rau-chaw nres nkoj. Daim duab 7 qhia txog qhov ua hla kev sib txuas rau cov kev sib txuas ob yam.

Peb yuav tham txog cov khoom uas yuav tsum txuas los txuas ob kab (8-fiber lossis 20-fiber) transceivers hauv ntu no. Cov kev cai no suav nrog tab sis tsis txwv rau: 40GBASE-SR4, 40GBASE-xSR4 / cSR4 / eSR4, 40GBASE-PLR4, 40GBASE-PSM4, 100GBASE-SR4, 100GBASE-eSR4, 100GBASE-PSM4, 100GBASE-SRM4.
Thaum sib txuas ncaj qha ob QSFP + lossis QSFP 28 transceivers, yuav tsum muaj 8-fiber MTP pob tw cable uas xav tau. Txhawm rau txuas ncaj qha ob qhov CFP transceivers, yuav tsum muaj 24-fiber MTP pob tw cable uas xav tau.
Daim duab 9 qhia tau hais tias muaj kev sib txuas rau ob txheej txheem CFP (20-fiber). Txhawm rau txhawm rau tawm CFPs kom xa cov teeb liab thoob plaws 8-fiber vaj tse, 1 x 3 breakout sam xauv nees (24-fiber MTP mus rau peb 8-fiber MTP) yog qhov yuav tsum tau ua. Txhawm rau kom muaj kev sib txuas rau ob lub ntsej muag 8-fiber ntau, peb tuaj yeem hloov kho lub nkoj tawg ntawm 8-fiber MTP (rab koob) thiab lub 24-fiber MTP lub cev los ntawm MTP (tsis muaj pinned) lub cev.
Daim duab 9: 20-fiber rau 20-fiber cuam tshuam
| Yam khoom | Kev piav qhia |
| 1 | 1 × 3 MTP breakout sam xauv nees cable (24-fiber MTP rau peb 8-fiber MTP) (pinned) |

| 3 | 24 txoj hlua hluav taws xob MTP pob tw cable, peb ceg 8-fiber ntau(tsis pinned) |
Cov ntawv tshaj tawm no qhia qhov luv luv ntawm cov ntsiab lus ntawm duplex thiab cov kab sib txuas qhov muag kho qhov muag thiab nthuav tawm qee cov kev sib txuas rau ob lub ntsej muag duplex lossis ob qho kev sib txuas. Cov khoom sib xws siv nyob rau hauv txhua txoj kev daws teeb meem tau sau dhau. Qhov kev xa mus deb thiab thaj chaw ua haujlwm yuav tsum ua tib zoo xav thaum thov txhua txoj kev daws teebmeem. Cov mus tib seem rau kev daws cov teeb meem sib txuas lus yuav tau tham txog nyob rau tom ntej no.
