I-Gigabit 1 i-optical 2 yombane i-fiber optic transceiver enekhwalithi ephezulu ehambelana ne-chip

Unokukhetha njani i-fiber optic transceiver?

I-Optical fiber transceivers iphula umda we-100 yeemitha zeentambo ze-Ethernet ekuhanjisweni kwedatha.Ukuxhomekeka kwi-high-performance switching chips kunye ne-cache enkulu, ngelixa ufezekisela ngokwenene ukuhanjiswa okungathinteliyo kunye nokutshintsha ukusebenza, banikezela nge-traffic elinganayo, ukuhlukaniswa kunye nokungqubuzana.Ukufunyanwa kwempazamo kunye neminye imisebenzi iqinisekisa ukhuseleko oluphezulu kunye nokuzinza ngexesha lokuhanjiswa kwedatha.Ke ngoko, iimveliso ze-fiber optic transceiver ziya kuhlala ziyinxalenye eyimfuneko yolwakhiwo lwenethiwekhi ixesha elide.Ke, kufuneka sizikhethe njani ii-fiber optic transceivers?

1. Uvavanyo lomsebenzi wePort
Vavanya ikakhulu ukuba izibuko ngalinye linokusebenza ngokwesiqhelo kwi-duplex state ye-10Mbps, 100Mbps kunye ne-half-duplex state.Kwangaxeshanye, kufuneka ivavanywe ukuba izibuko ngalinye linokukhetha ngokuzenzekelayo esona santya siphezulu sothumelo kwaye lithelekise ngokuzenzekelayo izinga losulelo lwezinye izixhobo.Olu vavanyo lunokubandakanywa kwezinye iimvavanyo.

2. Uvavanyo lokuhambelana
Ikakhulu ivavanya amandla okunxibelelana phakathi kwe-transceiver ye-fiber optical kunye nezinye izixhobo ezihambelana ne-Ethernet kunye ne-Fast Ethernet (kubandakanywa nekhadi lenethiwekhi, i-HUB, i-Switch, i-optical network card, kunye ne-optical switch).Imfuno kufuneka ikwazi ukuxhasa uxhulumaniso lweemveliso ezihambelanayo.

3. Iimpawu zokudibanisa ikhebula
Vavanya isakhono se-fiber optic transceiver ukuxhasa iintambo zenethiwekhi.Okokuqala, vavanya amandla onxibelelwano lweCandelo 5 leentambo zenethiwekhi ezinobude be-100m kunye ne-10m, kwaye uvavanye ukukwazi ukunxibelelana kweentambo zenethiwekhi ezinde zoDidi 5 (120m) zeempawu ezahlukeneyo.Ngethuba lovavanyo, i-port optical port ye-transceiver iyadingeka ukuba ikwazi ukudibanisa i-10Mbps kunye nesantya se-100Mbps, kwaye iphezulu kufuneka ikwazi ukuxhuma kwi-duplex epheleleyo ye-100Mbps ngaphandle kweempazamo zokudlulisa.Iintambo eziphothiweyo zodidi 3 azinakuvavanywa.Amanqaku angaphantsi angabandakanywa kwezinye iimvavanyo.

4. Iimpawu zokudluliselwa (izinga lokulahleka kokudluliselwa kweepakethi zedatha yobude obuhlukeneyo, isantya sothumelo)
Ikakhulu ivavanya izinga lokulahleka kwepakethi xa i-fiber optical transceiver optical port ihambisa iipakethi zedatha ezahlukeneyo, kunye nesantya sokuxhuma phantsi kwamazinga ahlukeneyo okudibanisa.Ngexabiso lokulahlekelwa kwepakethi, ungasebenzisa isofthiwe yokuvavanya enikezelwa yikhadi lenethiwekhi ukuvavanya isantya sokulahlekelwa kwepakethi xa ubungakanani bepakethi buyi-64, 512, 1518, 128 (ukhetho) kunye ne-1000 (ukhetho) ngamabhayithi phantsi kwamazinga ahlukeneyo okudibanisa., inani leempazamo zepakethe, inani leepakethi ezithunyelweyo nezifunyenweyo mazibe ngaphezu kwe-2,000,000.Isantya sothumelo lovavanyo sinokusebenzisa i-perform3, i-ping kunye nenye isoftware.

5. Ukuhambelana komatshini wonke kwiprotocol yothumelo lwenethiwekhi
Ivavanya ikakhulu ukuhambelana kwe-fiber optic transceivers kwiiprothokholi zenethiwekhi, ezinokuvavanywa kwiNovell, Windows kunye nezinye iimeko.Makuvavanywe ezi prothokholi zothungelwano zamanqanaba asezantsi ezinjenge-TCP/IP, IPX, NETBIOS, DHCP, njl. njl. mazivavanywe iiprothokholi ezifuna ukusasazwa.Ii-transceivers zamehlo ziyafuneka ukuxhasa ezi protocol (VLAN, QOS, COS, njl.).

6. Uvavanyo lobume besalathi-nkqubela
Ukuvavanya ukuba imeko yokukhanya kwesalathisi ihambelana nenkcazo yepaneli kunye nencwadana yomsebenzisi, kwaye ingaba ihambelana nemeko yangoku ye-fiber optic transceiver.
