Zithini iimpawu zefayibha yemowudi enye?

Iimpawu ze Ifayibha yemowudi enyeIsikhokelo esipheleleyo

I-fiber yemowudi enye (i-SMF) luhlobo lwe-fiber ye-optical eyenzelwe ukuthwala ukukhanya ngqo kwi-fiber ngaphandle kokulahleka okukhulu. Isetyenziswa kakhulu kunxibelelwano lwefowuni kunye nothungelwano ngenxa yokusebenza kwayo okuphezulu kumgama omde. Apha, sijonga iimpawu eziphambili ezenza i-SMF isebenze kangaka. ifayibha yemowudi enye yinketho ekhethwayo yokudlulisela idatha ngesantya esiphezulu.

1. Ububanzi be-core:
Ifayibha yemowudi enye inobubanzi obuncinci be-core, ngesiqhelo imalunga ne-8 ukuya kwi-10 micrometers. Le core incinci ivumela indlela enye yokukhanya ukuba isasazeke, inciphisa kakhulu ukusasazwa kwe-modal kwaye ivumela ukuhanjiswa kwedatha kumgama omde ngaphandle kokuwohloka.I-DACi-ion.

2. Ukungakhathali okuphantsi:
Enye yezona mpawu ziphambili zefayibha yemowudi enye kukuba isantya sayo sokunciphisa siphantsi. Ukunciphisa kubhekisa ekulahlekelweni kwamandla esignali njengoko ihamba kwifayibha. Iifayibha zemowudi enye zinamazinga okunciphisa aphantsi njenge-0.2 dB/km, nto leyo eyenza ukuba zilungele iinkqubo zonxibelelwano ezikude.

3. I-bandwidth ephezulu:
Iifayibha zemowudi enye zibonelela ngamandla aphezulu kakhulu e-bandwidth. Oku kuthetha ukuba zinokuxhasa amazinga aphezulu edatha xa kuthelekiswa neefayibha zemowudi ezininzi. I-bandwidth ephezulu ibalulekile kwizicelo ezifuna ukuhanjiswa kwedatha eninzi, njenge-backbones ye-intanethi kunye namaziko edatha.

4. Uthumelo olude:
Ngenxa yokuba azinamandla aneleyo okudlulisa umyalezo kunye ne-bandwidth ephezulu, iifayibha zemowudi enye zilungele ukusasazwa komgama omde. Zinokudlulisa imiyalezo kumgama ongaphezulu kweekhilomitha ezili-100 ngaphandle kwesidingo se-amplifiers zesignali okanye iziphindaphindi, nto leyo eyenza ukuba zisebenzise imali eninzi xa kusenziwa inethiwekhi enkulu.

5. Ukuhambelana kwe-Wavelength:
Iifayibha zemowudi enye ziyahambelana noluhlu olubanzi lweewavelengths, ezihlala zisebenza kwiifestile ze-1310 nm kunye ne-1550 nm. Ezi wavelengths azichaphazeleki lula kulahleko nokusasazeka, nto leyo ephucula ngakumbi ukusebenza kakuhle kwefayibha kunye nokusebenza kwayo.

6. Ukuphazamiseka okuncinci:
Iifayibha zemowudi enye azichaphazeleki lula kukuphazamiseka okuvela kwimithombo yangaphandle, njenge-electromagnetic interference (EMI) kunye ne-radio frequency interference (RFI). Oku kuqinisekisa isignali ecocekileyo nethembekileyo ngakumbi, ebalulekileyo kwizicelo zonxibelelwano ezibalulekileyo.
