1.Udidi lweLaser
I-laser iyona nxalenye ephambili yemodyuli ye-optical injecting current kwi-semiconductor material kwaye ikhupha ukukhanya kwe-laser ngokusebenzisa i-photon oscillations kunye nokuzuza kwi-cavity. Okwangoku, ezona lasers ziqhele ukusetyenziswa yiFP kunye neDFB lasers. Umahluko kukuba izinto ze-semiconductor kunye nesakhiwo secavity sihluke. Ixabiso lelaser yeDFB libiza kakhulu kunelaser yeFP. Iimodyuli ze-Optical ezinemigama yothumelo ukuya kwi-40KM ngokubanzi zisebenzisa iilaser zeFP; iimodyuli ze-optical ezinemigama yothumelo ≥40KM ngokubanzi zisebenzisa iilaser zeDFB.
2.Ilahleko kunye nokusasazeka
Ilahleko kukulahlekelwa kwamandla okukhanya ngenxa yokufunxa kunye nokusabalalisa okuphakathi kunye nokuvuza kokukhanya xa ukukhanya kuhanjiswa kwifiber. Le nxalenye yamandla ichithwa ngomlinganiselo othile njengoko umgama wothumelo unyuka. Ukusasazwa ikakhulu kubangelwa yisantya esingalinganiyo samaza ombane ombane asasazeke ngendlela efanayo, nto leyo ebangela amacandelo obude obuhlukeneyo bomqondiso wokukhanya ukufikelela isiphelo sokufumana ngamaxesha ahlukeneyo ngenxa yokuqokelela umgama wothumelo, okubangela ukwanda kwe-pulse kwaye ngaloo ndlela ukungakwazi ukwahlula ixabiso leempawu.Ezi zimbini zeeparamitha zichaphazela kakhulu umgama wokuhanjiswa kwemodyuli ye-optical. Kwinkqubo yesicelo sangempela, imodyuli ye-1310nm ye-optical ngokubanzi ibala ukulahleka kwekhonkco kwi-0.35dBm / km, kwaye imodyuli ye-optical ye-1550nm ngokubanzi ibala ukulahleka kwekhonkco kwi-.20dBm / km, kwaye ibala ixabiso lokusabalalisa. Intsonkothe kakhulu, ngokubanzi kuphela ireferensi.
3.Ukuhanjiswa kwamandla optical kunye nokufumana ubuntununtunu
I-optical power transmitted power ibhekisela kumandla okukhanya ophumayo omthombo wokukhanya ekupheleni kokuhambisa imodyuli ye-optical. Ukufumana ubuntununtunu kubhekiselele kumandla okukhanya afunyenweyo amancinci emodyuli ye-optical kwireyithi ethile kunye nebit error rate. Iiyunithi zezi parameters zimbini ziyi-dBm (ithetha i-decibel milliwatt, i-logarithm yeyunithi yamandla mw, i-formula yokubala yi-10lg, i-1mw iguqulelwa kwi-0dBm), esetyenziswa kakhulu ukuchaza umgama wothumelo lwemveliso, ubude bamaza ahlukeneyo, izinga lothumelo kunye namandla okuhambisa imodyuli ye-optical kunye nokufumana ubuntununtunu iya kwahluka, okoko nje umgama wothumelo unokuqinisekiswa.
4.Ubomi bemodyuli yokubona
Imigangatho emanyeneyo yamazwe ngamazwe, iiyure ezingama-50,000 zomsebenzi oqhubekayo, iiyure ezingama-50,000 (ezilingana neminyaka emi-5).
Iimodyuli ze-SFP ezibonakalayo zizo zonke ii-interfaces ze-LC. Iimodyuli ze-GBIC ezibonakalayo zizo zonke ii-SC interfaces. Olunye ujongano lubandakanya iFC kunye ne-ST.
