Puas yog fiber ntau optic transceivers yuav tsum tau siv ua khub?Puas muaj kev sib cais hauv fiber ntau transceiver?los yog ib khub ntawm fiber ntau optic transceivers tuaj yeem siv los ua ib khub?Yog tias cov fiber ntau transceivers yuav tsum tau siv ua khub, nws puas yog tib hom thiab qauv?Los yog koj tuaj yeem siv cov khoom sib xyaw ua ke?
Teb: Optical transceivers feem ntau yog siv ua khub li photoelectric hloov dua siab tshiab.Txawm li cas los xij, nws tseem tuaj yeem siv optical transceivers thiab fiber ntau hloov, fiber ntau transceivers thiab SFP transceivers.Nyob rau hauv txoj cai, ntev li ntev raws li qhov optical kis tau tus mob wavelength yog tib yam, Fiber-optic kev sib txuas lus yuav ua tau tiav los ntawm tib lub teeb liab encapsulation hom ntawv thiab txhawb ib tug tej yam raws tu qauv.
Feem ntau, dual-fiber (ob fibers yuav tsum tau rau kev sib txuas lus ib txwm) transceivers tsis muab faib mus rau hauv lub transmitting kawg thiab qhov kawg tau txais.Tsuas yog ib leeg-fiber transceiver (uas yuav tsum muaj ib qho fiber ntau rau kev sib txuas lus ib txwm muaj) yuav muaj qhov kawg xa tawm thiab qhov kawg tau txais.
Txawm hais tias nws yog dual-fiber transceiver los yog ib leeg-fiber transceiver, nws yog sib xws los siv ntau hom nyob rau hauv khub.Txawm li cas los xij, cov nqi sib txawv (100 megabits thiab gigabytes) thiab qhov sib txawv wavelengths (1310 nm thiab 1300 nm) tsis sib haum.Tsis tas li ntawd, txawm tias ib leeg-fiber transceiver ntawm tib hom thiab ib khub ntawm dual-fiber thiab dual-fiber khub tsis tuaj yeem cuam tshuam.
Lub dual-fiber transceiver muaj qhov chaw nres nkoj TX (chaw nres nkoj) thiab RX chaw nres nkoj (tau txais chaw nres nkoj).Ob qhov chaw nres nkoj emit tib lub wavelength ntawm 1310 nm, thiab qhov tau txais kuj yog 1310 nm, yog li qhov sib npaug ntawm ob lub fibers txuas nrog kev sib txuas ntawm kev sib txuas, ib leeg-fiber transceiver tsuas muaj ib qho chaw nres nkoj, uas siv ob qho tib si kis tau tus mob thiab tau txais kev ua haujlwm. .Nws siv lub wavelength division multiplexing thev naus laus zis los xa thiab tau txais ob lub teeb liab ntawm qhov sib txawv wavelengths ntawm ib qho fiber ntau optical.Feem ntau lawv siv wavelengths ntawm 1310 nm thiab 1550 nm.
Ntau hom ntawm optical transceivers txhawb Ethernet raws tu qauv.Lawv tuaj yeem sib txuas lus nrog cov transceivers ntawm tib qhov tshwj xeeb, tab sis qee qhov transceivers ntxiv qee qhov haujlwm (xws li mirroring) thiab txhawb qee cov kev cai.Nyob rau hauv rooj plaub no tsis txaus siab.
