I-transceiver ye-fiber optical transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye neempawu ze-optical ezide. Ikwabizwa ngokuba sisiguquli sefayibha kwiindawo ezininzi. Iimveliso zisetyenziswa ngokubanzi kwiindawo zonethwekhi zokwenyani apho iintambo ze-Ethernet zingenako ukugqunywa kwaye imicu ye-optical kufuneka isetyenziswe ukwandisa umgama wothumelo, kwaye idla ngokubekwa kwi-access layer application ye-broadband network networks.

Indima ye-fiber optic transceivers

I-Fiber optic transceivers isetyenziswa ngokubanzi kwiindawo zenethiwekhi zangempela apho iintambo ze-Ethernet azikwazi ukugqunywa kwaye iifiber zamehlo kufuneka zisetyenziswe ukwandisa umgama wokuhambisa. Kwangaxeshanye, baye badlala indima enkulu ekuncedeni ukudibanisa imayile yokugqibela yemigca yefiber ebonakalayo kuthungelwano lwendawo yemetropolitan kunye nothungelwano lwangaphandle. Indima ye. Umsebenzi we-fiber optic transceiver kukuguqula isignali yombane esifuna ukuyithumela kwisignali ye-optical kwaye siyithumele ngaphandle. Ngelo xesha, inokuguqula isignali ye-optical efunyenweyo ibe ngumqondiso wombane kwaye ifake kwisiphelo sethu sokufumana.

Ukuhlelwa kwei-fiber optic transceivers

I-1.I-transceiver ye-fiber optic yemodi enye: umgama wokuhambisa ukusuka kwiikhilomitha ezingama-20 ukuya kwi-120 yeekhilomitha.

I-2.I-Multimode fiber optic transceiver: umgama wokuhanjiswa kweekhilomitha ezi-2 ukuya kwiikhilomitha ezi-5.

Ngokomzekelo, amandla okuhambisa i-5km ye-fiber optic transceiver ngokuqhelekileyo phakathi kwe-20 kunye ne-14db, kwaye i-sensitivity efunyenweyo yi-30db, isebenzisa i-wavelength ye-1310nm; ngelixa amandla okuhambisa i-120km i-fiber optic transceiver ininzi phakathi kwe-5 kunye ne-0dB, kunye nokufumana uvakalelo lwe-38dB, sebenzisa ubude be-1550nm.

Iimpawu ze-fiber optic transceivers

Iitransceivers zeFiber optic zihlala zinezi mpawu zilandelayo:

1. Ukubonelela ngokuhanjiswa kwedatha ye-ultra-low latency.

2. Ngokucacileyo ngokupheleleyo kwiprotocol yenethiwekhi.

3. Sebenzisa i-ASIC chip ezinikeleyo ukuqonda ukuhanjiswa kwedatha ngesantya esiphezulu. I-ASIC eCwangcisiweyo igxininisa imisebenzi emininzi kwi-chip enye, kwaye ineenzuzo zoyilo olulula, ukuthembeka okuphezulu, kunye nokusetyenziswa kwamandla aphantsi, okunokwenza ukuba izixhobo zifumane ukusebenza okuphezulu kunye neendleko eziphantsi.

4. Izixhobo ze-Rack-type zinokubonelela ngomsebenzi oshushu-oguqulwayo ukuze kube lula ukugcinwa kunye nokuphuculwa okungaphazamisekiyo.

5. Izixhobo zolawulo lwenethiwekhi zinokubonelela ngemisebenzi efana nokuxilongwa kwenethiwekhi, ukuphuculwa, ingxelo yesimo, ingxelo yemeko engaqhelekanga kunye nokulawula, kwaye inokubonelela ngelog yokusebenza epheleleyo kunye ne-alarm log.

6. Uninzi lwezixhobo zisebenzisa i-1 + 1 yoyilo lonikezelo lwamandla, ixhasa i-voltage ye-ultra-wide yonikezelo lwamandla, kwaye iqonda ukukhuselwa kombane kunye nokutshintsha ngokuzenzekelayo.

7. Ukuxhasa uluhlu lweqondo lokushisa olubanzi kakhulu.

8. Ukuxhasa umgama opheleleyo wothumelo (iikhilomitha eziyi-0 ~ 120).

Izinto eziluncedo kwi-fiber optic transceivers

Xa kuziwa kwi-fiber optic transceivers, abantu bahlala bethelekisa ii-fiber optic transceivers ngokungenakuthintelwaiiswitshingamazibuko okukhanya. Oku kulandelayo kuthetha ikakhulu malunga neenzuzo ze-fiber optic transceivers ngaphezu kwe-optical portiiswitshi.

Okokuqala, ixabiso le-fiber optic transceivers kunye nesiqheloiiswitshiIxabiso eliphantsi kakhulu kune-opticaliiswitshi, ngakumbi i-opticaliiswitshilizakuphulukana nezibuko elinye okanye namazibuko amaninzi emva kokongeza iimodyuli zamehlo, ezinokwenza abaqhubi kubungakanani obukhulu Ukunciphisa utyalo-mali lwangaphambili.

Okwesibini, kuba uninzi lweemodyuli zamehlo zeiiswitshiayinayo umgangatho odibeneyo, emva kokuba iimodyuli ze-optical zonakaliswe, kufuneka zitshintshwe kunye neemodyuli ezifanayo ezivela kumenzi wokuqala, ezisa ingxaki enkulu ekugcinweni kwexesha elizayo. abavelisi abahlukeneyo be-fiber optic transceivers, ngoko ke xa yonakele, inokutshintshwa iimveliso zabanye abavelisi, ekulula kakhulu ukuyigcina.

Ukongeza, ii-transceivers zefiber optic zineemveliso ezipheleleyo kune-optical portiiswitshingokomgama wothumelo. Ngokuqinisekileyo, i-opticaltshintshakananjalo ineenzuzo kwimiba emininzi, njengolawulo olumanyeneyo kunye nonikezelo lwamandla olumanyeneyo.
