Izinto ezimbili ezibalulekile zokusebenzisa amamojula optical

Qaphela ukuthi amaphuzu amabili alandelayo angakusiza ukunciphisa ukulahlekelwa kwe-module optical futhi uthuthukise ukusebenza kwe-optical module.

Qaphela 1:

1. Kunamadivayisi e-CMOS kule chip, ngakho-ke qaphela ukuvimbela ugesi omile ngesikhathi sokuhamba nokusebenzisa.
2. Idivayisi kufanele yehliswe kahle ukuze kuncishiswe i-parasitic inductance.
3. Try to solder ngesandla, uma udinga izitikha zomshini, lawula izinga lokushisa lokugeleza kabusha alikwazi ukudlula ama-205 degrees Celsius.
4. Ungabeki ithusi ngaphansi kwemojula ye-optical ukuvimbela izinguquko ze-impedance.
5. I-antenna kufanele igcinwe ikude nezinye izifunda ukuze kuvinjelwe ukusebenza kahle kwemisebe ekubeni phansi noma kuthinte ukusetshenziswa okuvamile kwamanye amasekhethi.
6. Ukubekwa kwemojula kufanele kube kude ngangokunokwenzeka kwamanye amasekhethi aphansi, amasekhethi edijithali.
7. Kunconywa ukusebenzisa ubuhlalu obukazibuthe ukuze uhlukanise ukunikezwa kwamandla kwemojuli.

Inothi 2:

1. Awukwazi ukubheka ngqo imojuli ye-optical (kungaba ibanga elide noma i-short-range optical module) exhunywe kudivayisi ukugwema ukushiswa kwamehlo.
2. Ngemojula ye-optical yebanga elide, amandla optical adlulisiwe ngokuvamile makhulu kunamandla okubona agcwele kakhulu. Ngakho-ke, kuyadingeka ukunaka ubude be-fiber optical ukuqinisekisa ukuthi amandla optical wangempela atholiwe angaphansi kwamandla optical overload. Uma ubude be-fiber optical bufushane, udinga ukusebenzisa imojuli yebanga elide ukuze usebenzisane nokuncishiswa kwe-optical. Qaphela ukuthi ungashisi imojuli ye-optical.
3. Ukuze uvikele kangcono ukuhlanzwa kwemojula ye-optical, kunconywa ukuxhuma ipulaki yothuli uma ingasetshenziswa. Uma oxhumana nabo be-optical bengahlanzekile, kungase kuthinte ikhwalithi yesiginali futhi kungabangela izinkinga zesixhumanisi namaphutha amancane.
4. Imojuli yokubona ngokuvamile imakwa ngokuthi i-Rx/Tx, noma umcibisholo ongenayo noma ophumayo ukuze usize ukuhlonza isidlulisilwazi. I-Tx ngakolunye uhlangothi kufanele ixhunywe ku-Rx ngakolunye uhlangothi, ngaphandle kwalokho iziphetho ezimbili azikwazi ukuxhunyaniswa.
