I-Gigabit fiber optic transceiver (isibane esinye kunye nombane osi-8)

Zeziphi izalathi ze-optical fiber transceiver chip performance?
1. Umsebenzi wolawulo womnatha

Ulawulo lwenethiwekhi alunakuphucula kuphela ukusebenza kwenethiwekhi, kodwa luqinisekisa ukuthembeka kwenethiwekhi.Nangona kunjalo, amandla okusebenza kunye nezinto eziphathekayo ezifunekayo ukuphuhlisa i-fiber optic transceiver kunye nomsebenzi wokulawula inethiwekhi idlula kakhulu ezo zemveliso ezifanayo ngaphandle kokulawulwa kwenethiwekhi, ezibonakaliswa ngokukodwa kwiinkalo ezine: utyalo-mali lwe-hardware, utyalo-mali lwesofthiwe, umsebenzi wokulungisa, kunye notyalo-mali lwabasebenzi.

1. Utyalo-mali lwezixhobo zokusebenza

Ukuqonda umsebenzi wolawulo lwenethiwekhi ye-transceiver ye-fiber optical, kuyimfuneko ukuqwalasela iyunithi yokulawula ulwazi lwenethiwekhi kwibhodi yesekethe ye-transceiver ukucubungula ulwazi lolawulo lwenethiwekhi.Ngale yunithi, i-interface yolawulo ye-chip yokuguqula ephakathi isetyenziselwa ukufumana ulwazi lolawulo, kwaye ulwazi lolawulo lwabelwana ngedatha eqhelekileyo kwinethiwekhi.itshaneli yedatha.Ii-transceivers ze-fiber optical kunye nomsebenzi wolawulo lwenethiwekhi zineentlobo ezininzi kunye nobuninzi bamacandelo kuneemveliso ezifanayo ngaphandle kokulawulwa kwenethiwekhi.Ngokuhambelanayo, i-wiring inzima kwaye umjikelezo wophuhliso lude.

2. Utyalo-mali lweSoftware

Ukongeza kwi-wiring ye-hardware, inkqubo yesofthiwe ibaluleke kakhulu kuphando kunye nophuhliso lwe-Ethernet fiber optic transceivers kunye nemisebenzi yolawulo lwenethiwekhi.Umsebenzi wophuhliso we-software yolawulo lwenethiwekhi inkulu, kubandakanywa inxalenye ye-graphical interface yomsebenzisi, inxalenye yenkqubo edibeneyo yemodyuli yolawulo lwenethiwekhi, kunye nenxalenye yeyunithi yokulawula ulwazi lwenethiwekhi kwibhodi yesekethe ye-transceiver.Phakathi kwabo, inkqubo edibeneyo yemodyuli yolawulo lwenethiwekhi inzima kakhulu, kwaye i-R & D threshold iphezulu, kwaye inkqubo yokusebenza edibeneyo kufuneka isetyenziswe.

3. Umsebenzi wokulungisa ingxaki

Ukulungiswa kwe-Ethernet ye-transceiver optical kunye nomsebenzi wokulawula inethiwekhi kubandakanya iinxalenye ezimbini: ukuguqulwa kwesoftware kunye ne-hardware debugging.Ngexesha lokulungiswa kweempazamo, nayiphi na into ekuqhutyweni kwebhodi, ukusebenza kwecandelo, i-soldering component, umgangatho webhodi ye-PCB, iimeko zokusingqongileyo, kunye neprogram yeprogram inokuchaphazela ukusebenza kwe-Ethernet fiber optic transceiver.Abasebenzi bokulungisa iimpazamo kufuneka babe nomgangatho obanzi, kwaye baqwalasele ngokubanzi izinto ezahlukeneyo zokusilela kwe-transceiver.

4. Igalelo labasebenzi

Uyilo lweetransceivers zefiber optic eziqhelekileyo ze-Ethernet zinokugqityezelwa yinjineli yehardware enye kuphela.Uyilo lwe-Ethernet fiber optic transceiver enomsebenzi wolawulo lwenethiwekhi ayifuni nje kuphela ukuba iinjineli ze-hardware zigqibezele ii-wiring zebhodi yesekethe, kodwa zifuna iinjineli ezininzi zesoftware ukugqiba inkqubo yolawulo lwenethiwekhi, kwaye ifuna intsebenziswano esondeleyo phakathi kwesoftware kunye nabayili behardware.

2. Ukuhambelana

I-OEMC kufuneka ixhase imigangatho yonxibelelwano yenethiwekhi eqhelekileyo njenge-IEEE802, i-CISCO ISL, njl., Ukuqinisekisa ukuhambelana kakuhle kwe-fiber optic transceivers.

3. Iimfuno zokusingqongileyo

a.I-voltage yegalelo kunye nemveliso kunye ne-voltage yokusebenza ye-OEMC ininzi i-5 volts okanye i-3.3 volts, kodwa esinye isixhobo esibalulekileyo kwi-Ethernet fiber optic transceiver - i-voltage yokusebenza yemodyuli ye-transceiver optical ininzi i-5 volts.Ukuba ii-voltages ezimbini zokusebenza azihambelani, kuya kwandisa ukuntsokotha kweengcingo zebhodi yePCB.

b.Ubushushu bokusebenza.Xa ukhetha ubushushu bokusebenza be-OEMC, abaphuhlisi kufuneka baqale ukusuka kwezona meko zingathandekiyo kwaye bashiye indawo kuyo.Umzekelo, ubushushu obuphezulu ehlotyeni yi-40 ° C, kwaye ngaphakathi kwe-fiber optical transceiver chassis ifudunyezwa ngamacandelo ahlukeneyo, ngakumbi i-OEMC..Ke ngoko, isalathiso somda ophezulu wobushushu obusebenzayo be-Ethernet fiber optic transceiver akufanele ngokuqhelekileyo ibe ngaphantsi kwe-50 °C.
