1. Taw qhia ntawm 40G rau 10G Active Optical Cable (AOC)
QSFP-40GB-AOC-4SFP ntxiv rau cov khoom siv kho qhov muagtshwj xeeb yog siv rau kev sib txuas ntawm 40G QSFP cov chaw nres nkoj rau 10G SFP ntxiv rau cov chaw nres nkoj. Ib lub QSFP davhlau ya nyob twg thiab plaub SFP ntxiv cov davhlau ya nyob twg yog interconnected los ntawm ib tug multi-core multi-mode optical cable, raws li qhia nyob rau hauv daim duab hauv qab no, nyob rau hauv lub QSFP davhlau ya nyob twg Lub teeb engine yog tsim los ntawm VCSELs thiab PD arrays xa plaub khub ntawm lub teeb-emitting. thiab tau txais cov teeb liab los ntawm ntau qhov sib npaug ntawm cov fibers optical:
Plaub pawg ntawm transceiver optical signals yog kis los ntawmlub QSFPxaus rau plaub tus SFP ywj siab ntxiv rau cov khoom siv los ntawm cov khoom siv kho qhov muag sib luag, kom paub txog daim ntawv thov puv-duplex ntawm 40G rau 4-channel 10G. Cov ceg ntoo sib thooj yog raws li hauv qab no:
QSFP sab tau txais kev ntseeg siab VCSEL tso saib thev naus laus zis. Nws yog ua tiav los ntawm cov txheej txheem COB, thiab txhua pab pawg ntawm cov teeb liab sab hauv raug xa tawm ntawm nws tus kheej, yog li cov channel tuaj yeem ua haujlwm ntawm nws tus kheej yam tsis muaj kev cuam tshuam rau ib leeg. Los ntawm kev tswj hwm ntawm kev sau npe sab hauv ntawm QSFP, koj tuaj yeem hais qhia seb qhov sib raug zoo yog qhib lossis kaw. .
Los ntawm kev siv OM3 fiber ntau zoo, qhov sib kis ntawm QSFP-40GB-AOC-4SFP ntxiv tuaj yeem ncav cuag 300 meters, uas tuaj yeem ua tau raws li qhov kev ncua deb ntawm feem ntau cov kev sib kis hauv tsev. Ib qho kev xaiv zoo heev rau kev xaim.
