Raws li peb paub, ib qho SFP transceiver feem ntau muaj ob lub chaw nres nkoj, ib qho yog TX chaw nres nkoj uas yog siv los xa cov teeb liab, thiab lwm qhov yog RX chaw nres nkoj uas yog siv los txais cov teeb liab.Tsis zoo li ntau SFP transceiver, BiDi SFP transceiver tsuas yog nrog ib qho chaw nres nkoj uas siv ib qho WDM txuas rau xa thiab tau txais cov teeb liab hla ib leeg fiber ntau.Qhov tseeb, qhov compact SFP yog 2-channel BiDi SFP, uas sib txuas ob BiDi SFP hauv ib qho SFP module.Yog li ntawd, ib qho kev sib cog lus SFP kuj nrog ob lub chaw nres nkoj raws li SFP.

SFP, BiDi SFP thiab Compact SFP Connection Methods
Tag nrhoSFP transceiversyuav tsum tau siv ua khub.Rau ib qho SFPs, peb yuav tsum txuas ob SFPs uas muaj tib lub wavelength ua ke.Piv txwv li, peb siv 850nm SFP ntawm ib qho kawg, tom qab ntawd peb yuav tsum siv 850nm SFP ntawm lwm qhov kawg (pom hauv daim duab hauv qab).

RauBiDi SFP, txij li nws xa thiab tau txais cov teeb liab nrog cov wavelengths sib txawv, peb yuav tsum txuas ob BiDi SFPs uas muaj qhov sib txawv wavelength ua ke.Piv txwv li, peb siv 1310nm-TX / 1490nm-RX BiDi SFP ntawm ib kawg, ces peb yuav tsum siv 1490nm-TX / 1310nm-RX BiDi SFP ntawm lwm qhov kawg.
Compact SFP (GLC-2BX-D) feem ntau siv 1490nm los xa cov teeb liab thiab 1310nm kom tau txais cov teeb liab.Yog li ntawd, lub compact SFP ib txwm txuas nrog ob 1310nm-TX / 1490nm-RX BiDi SFP tshaj ob hom fibers.

BiDi SFP thiab Compact SFP Daim Ntawv Thov
Tam sim no, BiDi SFP feem ntau yog siv hauv FTTx xa tawm P2P (point-to-point) kev sib txuas.FTTH / FTTB nquag Ethernet network muaj lub chaw ua haujlwm hauv nruab nrab (CO) txuas rau cov khoom siv hauv tsev (CPE).Active Ethernet tes hauj lwm siv P2P architecture uas txhua tus neeg siv khoom kawg tau txuas nrog CO ntawm cov fiber ntau.BiDi SFP tso cai rau kev sib txuas lus ob-txoj kev ntawm ib qho fiber ntau los ntawm kev siv wavelength multiplexing (WDM), uas ua rau CO thiab CPE kev sib txuas yooj yim dua.Compact SFP enormously tsub kom CO chaw nres nkoj ceev los ntawm combining ob ib fiber transceivers rau hauv ib tug SFP daim ntawv.Tsis tas li ntawd, lub compact SFP yuav txo qis tag nrho lub zog siv ntawm CO sab.

JHA-Tech BiDi thiab Compact SFP Sloutions
JHA-Tech muab ntau yam BiDi SFPs.Lawv tuaj yeem txhawb nqa cov ntaub ntawv sib txawv thiab txhawb kev sib kis mus txog 120 km uas tuaj yeem ua tau raws li qhov xav tau ntawm cov kev pabcuam fiber ntau niaj hnub no rau cov neeg nqa khoom thiab cov lag luam.
