Nrog rau cov txheej txheem digitalization, cov ntaub ntawv ua, khaws cia thiab xa tawm tau tsim nyob rau hauv leaps thiab ciam teb. Kev loj hlob sai ntawm cov ntaub ntawv tes hauj lwm xav tau kev ua haujlwm siab, siab bandwidth, kev ntseeg siab, cov ntaub ntawv tsis tshua muaj nqi sib kis. Piv nrog rau kev sib txuas hluav taws xob ib txwm muaj, fiber ntau optical interconnections muaj qhov zoo ntawm cov bandwidth siab, tsis tshua muaj kev poob qis, kev ncua deb crosstalk-dawb thiab electromagnetic compatibility.
Ib tug xov tooj ntawm optical transceivers thiab fiber optic thaj qaum los tsim ib txheej ntawm cov ntaub ntawv kev sib txuas lus interconnection system, uas yog, active fiber optic cable. Piv nrog rau kev sib txuas ntawm cov kab ke tsim los ntawm cov khoom ywj pheej (optical transceiver module, fiber ntau optic thaj qaum) muaj kev ceev dua thiab kev ntseeg siab, ua rau lub kaw lus qis dua thiab yooj yim rau kev tswj xyuas.
AOC qauv
AOC= Optical Transceiver ntxiv rau fiber ntau optic thaj qaum
Cov kab hluav taws xob kho qhov muag tuaj yeem muab faib ua peb qhov chaw ua haujlwm: optical transmitting part, optical txais ib feem, thiab tswj Circuit Court.
Optical transmitting ib feem muaj: VSCEL laser, saib xyuas diode, tsav tsheb thiab tswj Circuit Court, thiab lwm yam.
Optical transmitting yog los hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag rau kev sib kis ntawm optical fiber, feem ntau suav nrog cov teeb liab hloov kho, hloov kho qhov chaw ua haujlwm zoo li qub thiab tsis siv neeg lub zog tswj hluav taws xob sub-circuit, nrog rau kev txwv tsis pub xa tawm thiab saib xyuas cov khoom tso tawm.
Optical txais ib feem: photodiode (PIN), transimpedance amplifier (TIA) thiab auxiliary circuits.
Kev txais tos kho qhov muag yog los hloov cov teeb liab tsis muaj zog hauv cov fiber ntau rau hauv cov teeb liab hluav taws xob, thiab lub transimpedance amplifier (TIA) outputs ib tug limiting hluav taws xob teeb liab uas tsis muaj lub teeb tswb muaj nuj nqi.
AOC kis txoj cai
NojQSFP plus AOCRaws li qhov piv txwv, ob qhov kawg ntawm cable (A kawg thiab B kawg) yog QSFP optical module pab kiag li lawm, ntawm A kawg, cov ntaub ntawv tawm tswv yim Din yog lub teeb liab hluav taws xob, thiab cov teeb liab hluav taws xob tau hloov mus rau hauv cov teeb liab kho qhov muag ntawm ib qho tshwj xeeb. wavelength los ntawm cov khoom siv hluav taws xob-rau-kho qhov muag hloov pauv (E / O Converter), thiab cov teeb liab kho qhov muag tau nkag mus rau hauv qhov kho qhov muag cable tom qab kev hloov kho thiab txuas; Tom qab lub teeb liab kho qhov muag mus txog B kawg los ntawm cov kab hluav taws xob kho qhov muag, cov khoom siv kho qhov muag (O / E Converter) kuaj pom cov teeb liab kho qhov muag thiab tso tawm cov teeb liab hluav taws xob sib thooj los ntawm Dout. Cov teeb liab kho qhov muag raug xa mus symmetrically ntawm B thiab A kawg.
Parallel optical interconnection yog pom tau los ntawm cov khoom siv kho qhov muag sib txuas thiab ribbon optical cables. Parallel optical modules yog raws li VCSEL arrays thiab PIN arrays nrog wavelengths ntawm 850nm, haum rau multimode fiber ntau 50/125um thiab 62.5/125um. Nyob rau hauv cov nqe lus ntawm ntim, txheem MegArray connectors yog siv rau cov hluav taws xob interface thiab txheem MTP / MPO ribbon fiber cables rau lub kho qhov muag interface. Tam sim no, ntau qhov sib npaug ntawm cov khoom siv kho qhov muag yog 4- txoj kev transceiver thiab 12- txoj kev transceiver cais module.
