Rau optical transceivers, txawm tias ib qho fiber ntau lossis dual fiber ntau yog qhov zoo dua, cia peb nkag siab txog dab tsi ib fiber ntau thiab dual fiber ntau yog.

Ib leeg fiber ntau: Cov ntaub ntawv tau txais thiab xa mus rau ntawm ib qho fiber ntau optical.
Dual fibers: Cov ntaub ntawv tau txais thiab xa tawm yog xa mus rau ob-core optical fibers feem.

Ib leeg-fiber bidirectional optical modules kim dua, tab sis tuaj yeem txuag tau ib qho khoom siv fiber ntau, uas yog qhov kev xaiv zoo dua rau cov neeg siv khoom siv fiber ntau tsis txaus.
Lub dual-fiber bidirectional optical module kuj pheej yig, tab sis xav tau ib qho ntxiv fiber ntau.Yog tias cov khoom siv fiber ntau txaus, koj tuaj yeem xaiv dual-fiber optical module.

Yog li rov qab mus rau lo lus nug dhau los, puas yog ib qho fiber ntau lossis dual fiber ntau zoo dua rau optical transceiver?

Ib leeg-fiber optical transceivers tuaj yeem txuag tau ib nrab ntawm cov khoom siv fiber ntau, uas yog, cov ntaub ntawv xa tawm thiab txais tos ntawm ib lub tub ntxhais fiber ntau, uas yog qhov tsim nyog rau cov chaw uas muaj fiber ntau nruj;thaum dual-fiber optical transceivers yuav tsum tau nyob rau hauv ob-core optical fiber, ib tug tub ntxhais yog siv rau kis tau tus mob (Tx) Ib tug tseem ceeb yog siv rau tau txais (Rx).Feem ntau wavelengths ntawm ib leeg-fiber optical transceivers yog 1310nm thiab 1550nm rau kev siv ua ke, uas yog, ib kawg yog 1310 wavelength, thiab lwm qhov kawg yog 1550 wavelength, uas tuaj yeem xa lossis tau txais.

Lub dual-fiber optical transceivers txhua tus muaj ib lub teeb wavelength, uas yog, cov khoom siv ntawm ob qhov kawg siv tib lub wavelength.Txawm li cas los xij, vim tsis muaj kev sib koom ua ke thoob ntiaj teb tus qauv rau cov khoom siv kho qhov muag transceiver, tej zaum yuav muaj kev tsis sib haum xeeb ntawm cov khoom ntawm cov tuam txhab sib txawv thaum lawv sib cuam tshuam.Tsis tas li ntawd, vim yog kev siv wavelength division multiplexing, ib leeg-fiber optical transceiver cov khoom muaj teeb meem attenuation, thiab lawv stability yog me ntsis phem dua li dual-fiber khoom, uas yog, ib leeg-fiber optical transceivers muaj ntau dua yuav tsum tau rau optical modules, yog li ib leeg-fiber optical transceivers ntawm kev ua lag luam kuj yog Dual-fiber optical transceivers kuj kim dua.

Lub multi-mode transceiver tau txais ntau hom kev sib kis, qhov sib kis ntawm qhov deb kuj luv, thiab ib hom transceiver tsuas tau txais ib hom nkaus xwb;qhov kis tau tus mob nyob deb kuj ntev.Txawm hais tias ntau hom tau raug tshem tawm, tseem muaj ntau daim ntawv thov hauv kev saib xyuas thiab kev sib kis luv luv vim tias tus nqi qis dua.Multi-mode transceivers sib haum mus rau ntau hom fibers, thiab ib hom thiab ib hom yog sib xws.Lawv tsis tuaj yeem sib xyaw.

Tam sim no, feem ntau optical transceivers nyob rau hauv kev ua lag luam yog dual-fiber cov khoom, uas kuj paub tab thiab ruaj khov, tab sis yuav tsum tau ntau optical cable kev pab cuam.
