Vim li cas SFP optical modules nrov?

Qhov ntim ntawm lubSFP optical moduleyog txo los ntawm ib nrab piv nrog lub ntim ntawm GBIC optical module. Tus naj npawb ntawm SFP cov chaw nres nkoj ntawm tib lub vaj huam sib luag yuav yog ob npaug ntawm GBIC optical module. Tib qhov SFP optical modules muaj qhov ntsaws-thiab-ua si mini optical fiber ntau qhov, uas ua raws li cov ntaub ntawv Nrog cov kev xav tau siab nyob hauv qhov chaw, SFP optical modules yuav hloov GBIC optical modules hauv cov ntaub ntawv chaw nyob rau yav tom ntej.

Nrov SFP optical modules

Vim hais tias SFP optical modules ntawm GLC-BX-D thiab GLC-BX-U yog cov muaj zog thiab nrhiav tau tom qab, ob hom optical modules txhawb cov ntaub ntawv kho qhov muag, tso cai rau cov neeg siv los saib xyuas kev ua haujlwm ntawm optical modules hauv lub sijhawm, xws li Kev ntsuas kub, lub teeb tso zis hluav taws xob, lub zog hluav taws xob kho qhov muag, laser bias tam sim no, transceiver fais fab mov voltage, thiab lwm yam. Tsis tas li ntawd, 1000BASE-BX10-D SFP Optical module nrog kev sib kis ntawm 10km, GLC-BX40-D SFP optical module nrog kev sib kis ntawm 40km, thiab GLC-BX80-D SFP optical module nrog kev sib kis ntawm 80km kuj nrov ntawm cov neeg siv.

SFP optical module muaj plaub qhov zoo hauv qab no:

1. Txhawb kev sib pauv kub, uas tuaj yeem txo qhov kev teeb tsa, txij nkawm thiab tswj lub sijhawm;

2. Qhov chaw nres nkoj yog hloov tau;

3. Cov qauv tsim muaj zog txhawb kev ntseeg tau;

4. Txhawb nqa digital optical saib xyuas (DOM) muaj nuj nqi.

Daim ntawv thov ntawm SFP optical module

1. Kev xaim hluav taws xob luv luv 1000BASE-T SFP optical module txhawb 10/100/1000 adaptive thiab Auto MDI / MDIX, thiab siv tau nrog qeb 5 unshielded network thaj qaum; qhov kis tau tus mob mus txog 100m. 1000BASE-SX SFP optical module yog sib xws nrog IEEE 802.3z 1000BASE-SX tus qauv, thiab tuaj yeem siv rau hauv 50μm / 62.5μm multimode fiber txuas nrog qhov siab tshaj plaws kis tau tus mob ntawm 550m.

2. Kev xaim hluav taws xob ntev 1000BASE-EX thiab 1000BASE-ZX SFP optical modules tuaj yeem siv nrog ib hom kho qhov muag fibers thiab tsim nyog rau kev sib kis mus ntev. Qhov kev ncua deb ntawm 1000BASE-EX SFP optical modules tuaj yeem ncav cuag 40km, thiab kev sib kis ntawm 1000BASE-ZX SFP optical modules tuaj yeem ncav cuag 80km.

Lus Cim: Thaum ib hom fiber ntau (SMF) siv rau qhov kev ncua deb, txhawm rau kom tsis txhob muaj ntau dhau ntawm tus txais, yuav tsum tau muab tso rau hauv qhov txuas. Tom qab cov lus qhia saum toj no, koj puas pom tias qhov chaw nres nkoj SFP tuaj yeem txhawb nqa SFP cov chaw nres nkoj hluav taws xob thiab SFP optical chaw nres nkoj modules? Txawm li cas los xij SFP cov chaw nres nkoj thiab SFP optical modules muaj qhov hloov pauv tau yooj yim thiab ua tau zoo hauv cov ntawv thov, Koj qhov kev daws teeb meem zoo tshaj plaws rau Gigabit Ethernet.
