Optical fiber transceiver yog ib qho yooj yim thiab siv tau zoo photoelectric hloov dua siab tshiab ntaus ntawv uas plays lub luag hauj lwm tseem ceeb nyob rau hauv multi-protocol photoelectric hybrid LAN. Tam sim no, nyob rau hauv thiaj li tau pom zoo dua thiab tshem tawm cov kev sib txawv, qee txoj kev hloov kho kho kho software muaj qhov txuas undover (LFP) thiab cov kab tawm chaw deb (FEF) tswb ua haujlwm.
Ua ntej peb thawj zaug qhia qhov txuas tsis ua haujlwm (LFP) thiab tej thaj chaw deb txhaum (FEF) lub tswb ua haujlwm ntawm fiber ntau transceivers, nws yuav tsum nkag siab txog lub luag haujlwm ntawm fiber ntau transceivers hauv LAN.
Lub optical fiber transceiver muaj ob qho tib si hluav taws xob ports thiab optical ports, uas feem ntau yog siv los txuas rau qhov chaw nres nkoj optical.hloovthiab qhov chaw nres nkoj hluav taws xobhloov, yog li kom paub txog kev hloov pauv photoelectric ntawm ob lub cuab yeej. Cov ntsiab lus yog raws li nram no:
Kev lees paub, lub luag haujlwm tseem ceeb ntawm optical fiber transceiver yog ua kev hloov pauv photoelectric, uas yog tus choj ntawm ob lub cuab yeej uas tsis tuaj yeem sib txuas lus ncaj qha, tab sis nws txoj haujlwm yog ntau tshaj qhov ntawd.
Thaum siv cov fiber ntau transceiver ua khub, cov cables siv muaj tsawg kawg yog ob lub fiber optic cables thiab ob cables (raws li qhia hauv qab no). Nws yog qhov nyuaj ntawm cov cabling no uas ua rau qhov txuas tsis ua haujlwm (LFP) thiab qhov tsis raug cuam tshuam (FEF) lub tswb ua haujlwm ntawm fiber ntau transceiver.
Link failover (LFP) yog hais txog ob qho khoom siv sib txuas lus (transceiver,hloov, router, thiab lwm yam), ib qho (proximal) txuas qhov txhaum, qhov txuas qhov txhaum tuaj yeem xa mus rau lwm qhov (chaw taws teeb) cov khoom siv piv txwv li, ob lub fiber ntau transceivers A thiab B, A transceiver chaw nres nkoj txuas txhaum, qhov chaw nres nkoj transceiver txhaum rau lub teeb chaw nres nkoj, nres cov ntaub ntawv chaw nres nkoj; B transceiver tsis tuaj yeem tau txais A cov ntaub ntawv, tom qab ntawd paub A txuas qhov txhaum, lub davhlau ya nyob twg B yuav nres lub teeb chaw nres nkoj thiab cov ntaub ntawv chaw nres nkoj. Link failover (LFP) tswb muaj nuj nqi ua rau cov thawj coj hauv lub network kom paub sai sai thiab daws cov teeb meem hauv lub network thiab txo qhov poob los ntawm kev ua haujlwm hauv network.
Tej thaj chaw deb txhaum (FEF) yog hais txog B optical fiber transceiver thaum qhov chaw nres nkoj kho qhov muag ntawm A transceiver nres xa cov ntaub ntawv mus rau qhov chaw nres nkoj qhov muag ntawm B transceiver. Yog tias lwm lub cable ua haujlwm zoo, qhov chaw nres nkoj kho qhov muag ntawm B transceiver tseem xa cov ntaub ntawv mus rau qhov chaw nres nkoj kho qhov muag ntawm A transceiver, ua rau lub network tsis ua haujlwm. Lub tswb distal fault (FEF) qhia txog qhov teeb meem no.
Cov saum toj no yog cov lus piav qhia ntawm transceiver LFP thiab FEF zog coj los ntawm Shenzhen HDV Phoelectronic Technology Co., LTD. Peb cov khoom siv sib txuas sib txuas muaj ONU series,OLTseries, optical module series, txais tos rau kev sib tham ntxiv.
