Rau cov fiber ntau optical transceivers, lub luag haujlwm tseem ceeb ntawm transceiver yog txhawm rau txuas lub network sib kis deb, uas tuaj yeem txo qhov tsis xws luag uas lub network cable tsis tuaj yeem xa mus rau qhov ntev mus rau qee qhov, thiab ua kom yooj yim mus rau qhov kawg kis kab mob, tab sis rau cov leej twg yog tus tshiab rau lub transceiver Qee qhov kev ua yuam kev feem ntau yog ua los ntawm tib neeg, xws li qhov tsis sib xws ntawm qhov kawg ntawm kev xa tawm thiab qhov kawg tau txais ntawm fiber ntau optic transceiver.Vim li cas fiber optic transceivers muab faib ua transmitter thiab receiver?Puas yog A / B kawg ntawm fiber ntau optic transceiver txuas nrog casually?

AB kawg ntawm fiber ntau optic transceiver yuav tsum yog qhov kawg (ib kawg) thiab txais qhov kawg (b kawg).Yog vim li cas vim li cas lub transceiver tau muab faib ua qhov kawg ntawm qhov kawg thiab qhov kawg tau txais yog tias lub transceiver yuav tsum xa cov teeb liab bidirectionally thaum nws siv, feem ntau yog ua khub.Ntau tus neeg siv ib leeg-fiber transceivers hauv khw;Ob qhov kawg ntawm ib leeg-fiber transceiver yog A-kawg thiab B-kawg feem.Lub wavelengths ntawm ob qhov kawg no txawv.Lub wavelength ntawm qhov kawg transmitting yog luv dua li ntawm qhov kawg tau txais.Qhov tseeb, lub dual-fiber transceiver tsis muaj qhov kawg A thiab B, vim tias lub wavelengths ntawm ob qhov kawg yog tib yam.Tsuas yog thaum txuas rau TX (transmitting) kawg thiab RX (tau txais) kawg, ib qho fiber ntau, raws li lub npe qhia, yog fiber ntau optical, thiab qee cov kws tshaj lij hu nws ib leeg-core transceiver, uas yog hais txog kev xa thiab tau txais. Cov teeb liab ntawm ob qho tag nrho ntawm ib qho khoom siv kho qhov muag, vim hais tias nyob rau hauv ib hom Kev kho qhov muag module siv nyob rau hauv ib leeg-fiber transceiver muaj ob lub wavelengths ntawm emitted lub teeb, thaum lub dual-fiber yog cross-connected los ntawm ob optical fibers, thiab sab hauv optical zaj duab xis. block tsuas muaj ib lub wavelength xwb.

Optical fiber ntau transceivers tau muab faib ua ib hom dual-fiber optical fiber ntau transceivers thiab ib hom single-fiber optical fiber transceivers raws li tus naj npawb ntawm fiber ntau cores.Ib hom ib leeg-fiber transceiver yog kis los ntawm cov tub ntxhais kho qhov muag fiber ntau, yog li ob qho tib si kis tau tus mob thiab tau txais lub teeb raug xa mus los ntawm ib qho kev kho qhov muag fiber ntau tib lub sijhawm. siv los paub qhov txawv.Yog li ntawd, lub optical module ntawm ib hom ib leeg-fiber transceiver muaj ob lub wavelengths ntawm lub teeb, feem ntau 1310nm / 1550nm, thiab qhov ntev yog 1490nm / 1550nm.Nyob rau hauv txoj kev no, yuav muaj qhov sib txawv ntawm ob qhov kawg ntawm kev sib tshuam ntawm ib khub ntawm transceivers, thiab ib qho kawg ntawm transceiver yuav txawv.Xa 1310nm thiab tau txais 1550nm.Lwm qhov kawg yog xa 1550nm thiab tau txais 1310nm.Yog li nws yooj yim rau cov neeg siv kom paub qhov txawv, thiab cov ntawv feem ntau yog siv los hloov.Tom qab ntawd muaj qhov kawg (1310nm / 1550nm) thiab B-end (1550nm / 1310nm).Cov neeg siv yuav tsum siv ab pairing.Aa lossis bb txuas tsis raug tso cai.
