Iingqwalasela ezimbini ezibalulekileyo zokusebenzisa iimodyuli zamehlo

Qaphela ukuba amanqaku amabini alandelayo anokukunceda ukunciphisa ilahleko yemodyuli ye-optical kunye nokuphucula ukusebenza kwemodyuli ye-optical.

Qaphela 1:

1. Kukho izixhobo zeCMOS kule chip, ngoko ke nikela ingqalelo ekuthinteleni umbane ongatshintshiyo ngexesha lothutho kunye nokusetyenziswa.
2. Isixhobo kufuneka sibekwe kakuhle ukunciphisa i-parasitic inductance.
3. Try to solder ngesandla, ukuba ufuna izitikha zoomatshini, ubushushu bokulawula ukuqukuqela kwakhona akunakudlula i-205 degrees Celsius.
4. Musa ukubeka ubhedu phantsi kwemodyuli ye-optical ukukhusela utshintsho lwe-impedance.
5. I-eriyali kufuneka igcinwe kude kwezinye iisekethe ukuthintela ukusebenza kakuhle kwemitha ukuba ibe phantsi okanye kuchaphazele ukusetyenziswa okuqhelekileyo kwezinye iisekethe.
6. Ukubekwa kwemodyuli kufuneka kube kude kangangoko kunokwenzeka kwezinye iisekethe eziphantsi, iisekethe zedijithali.
7. Kucetyiswa ukuba usebenzise amaso kazibuthe ukwahlula unikezelo lwamandla lwemodyuli.

Inqaku lesi-2:

1. Awukwazi ukujonga ngokuthe ngqo imodyuli ye-optical (nokuba ngumgama omde okanye i-short-range optical module) efakwe kwisixhobo ukunqanda ukutshisa kwamehlo.
2. Ngomgama omde wemodyuli ye-optical, amandla optical adlulisiweyo ngokuqhelekileyo makhulu kunamandla optical overload. Ngoko ke, kuyimfuneko ukubeka ingqalelo kubude be-fiber optical ukuqinisekisa ukuba amandla optical afunyenweyo angaphantsi kwamandla optical overload. Ukuba ubude be-fiber optical bufutshane, kufuneka usebenzise imodyuli ye-optical ye-long-distance optical ukuba usebenzisane kunye nokunyanzeliswa kwe-optical. Qaphela ukuba ungayitshisi imodyuli ye-optical.
3. Ukuze ukhusele kangcono ukucocwa kwemodyuli ye-optical, kucetyiswa ukuba udibanise iplagi yothuli xa ingasetyenziswa. Ukuba abafowunelwa bamehlo abacocekanga, kunokuchaphazela umgangatho wophawu kwaye kunokubangela iingxaki zekhonkco kunye neempazamo zebit.
4. Imodyuli ye-optical iphawulwe ngokubanzi nge-Rx/Tx, okanye utolo ngaphakathi nangaphandle ukuze kube lula ukuchongwa kwe-transceiver. I-Tx kwelinye icala kufuneka ixhunywe kwi-Rx kwelinye icala, ngaphandle koko iziphelo ezimbini azikwazi ukudibaniswa.
