Yintoni eyona njongo yefiber optic transceiver?

Umsebenzi we-fiber optical transceiver bai ngolu hlobo lulandelayo: luguqula umqondiso wombane esifuna ukuwuthumela kwisignali ye-optical kwaye uyithumele ngaphandle.Ngelo xesha, inokuguqula isignali ye-optical efunyenweyo ibe ngumqondiso wombane kwaye ifake kwisiphelo sethu sokufumana.

I-Optical fiber transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokukhanya ekude.Ikwabizwa ngokuba yi-photoelectric converter kwiindawo ezininzi.

Iimveliso zisetyenziswa ngokubanzi kwiindawo zothungelwano zokwenyani apho iintambo ze-Ethernet zingenako ukugqunywa kwaye iintsinga zamehlo kufuneka zisetyenziselwe ukwandisa umgama wothumelo, kwaye zihlala zibekwe kwindawo yokufikelela kwizicelo zothungelwano lwendawo yemetropolitan yeBroadband, ezifana nokuhanjiswa kwemifanekiso yevidiyo ephezulu. iiprojekthi zokhuseleko lokucupha.

Kwangaxeshanye, ikwadlale indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber optic kuthungelwano lwendawo yemetropolitan kunye nenethiwekhi yangaphandle.

Ulwazi olongeziweyo:

Imo yodibaniso lweFiber optic transceiver:

1.Ring umqolo womnatha.

Uthungelwano lwe-ring backbone network lusebenzisa uphawu lwe-SPANNING TREE ukwakha umqolo ngaphakathi kommandla wemetropolitan.Esi sakhiwo sinokuguqulwa sibe sisakhiwo se-mesh, esilungele iiseli ezisembindini ezinoxinaniso oluphezulu kuthungelwano lwengingqi yemetropolitan, kwaye zenze inethiwekhi yomqolo yomqolo enyamezela impazamo.

Inkxaso yenethiwekhi ye-backbone ye-IEEE.1Q kunye ne-ISL network network features inokuqinisekisa ukuhambelana nobuninzi be-backbone networks, njenge-cross-switch VLAN, i-trunk kunye neminye imisebenzi.Uthungelwano lomqolo weringi lunokwenza uthungelwano lwe-broadband virtual yabucala kumashishini afana nezezimali, urhulumente, kunye nemfundo.

2. Umnatha womqolo omile okwekhonkco.

Inethiwekhi ye-backbone ye-chain-shaped backbone inokugcina isixa esikhulu sokukhanya kwe-backbone ngokusetyenziswa koqhagamshelwano olubunjwe ngamakhonkco.Ilungele ukwakhiwa kwe-bandwidth ephezulu kunye nexabiso eliphantsi lothungelwano lwe-backbone ekupheleni kwesixeko kunye neendawo ezikufutshane.Le modi ingasetyenziselwa oohola beendlela, ioli kunye nokuhanjiswa kwamandla.Imigca kunye nezinye iimeko.

Inethiwekhi ye-backbone ye-chain-shaped backbone isekela i-IEEE802.1Q kunye ne-ISL network network features, enokuqinisekisa ukuhambelana nobuninzi be-backbone networks, kwaye inokwenza inethiwekhi ye-broadband ebonakalayo yabucala kumashishini afana nezezimali, urhulumente kunye nemfundo.

Inethiwekhi ye-backbone ye-chain yinethiwekhi ye-multimedia enokubonelela ngokusasazwa okudibeneyo kwemifanekiso, ilizwi, idatha kunye nokubeka iliso ngexesha langempela.

3. Umsebenzisi ufikelela kwinkqubo.

Inkqubo yokufikelela komsebenzisi isebenzisa i-10Mbps / 100Mbps eguquguqukayo kunye ne-10Mbps / 100Mbps yokuguqula ngokuzenzekelayo imisebenzi yokudibanisa nasiphi na isixhobo sokuphela komsebenzisi ngaphandle kokulungiselela i-transceivers ye-fiber optical multiple, enokubonelela ngesicwangciso sokuphucula ngokukhawuleza kwinethiwekhi.

Kwangaxeshanye, usebenzisa isiqingatha se-duplex/i-duplex epheleleyo kunye nesiqingatha se-duplex/i-full-duplex ezenzekelayo yoguqulo lwemisebenzi, i-HUB enexabiso eliphantsi enesiqingatha-ephindwe kabini inokuqwalaselwa kwicala lomsebenzisi, ecutha iindleko zenethiwekhi yecala lomsebenzisi nge. amaxesha ambalwa kwaye iphucula abasebenzisi benethiwekhi.Ukukhuphisana.
