Ake ngiqale ngokukhumbula ingxoxo edlule lapho ngachaza khona ukuthi iyini ikhebula le-fiber optic. Manje ufuna ukuqhathanisa, ngakho-ke ngidinga ukugqamisa umehluko phakathi kwalokhu okubili.

Ikhebula le-Fiber Optic ngokumelene Ikhebula Lethusi

Okokuqala, kufanele ngicabangele izici eziyinhloko okufanele ngiziqhathanise. Mhlawumbe indlela yokudlulisa, isivinini, ibanga, i-bandwidth, ukuphazamiseka, ukuphepha, izindleko, ukuqina, kanye nezinhlelo zokusebenza. Ake ngiqiniseke ukuthi ngihlanganisa wonke la maphuzu.

I-transmission medium: I-fibre isebenzisa ukukhanya, ithusi isebenzisa izimpawu zikagesi. Lowo umehluko obalulekile. Isivinini kanye ne-bandwidth: I-fibre ishesha kakhulu nge-bandwidth ephezulu. Ibanga: I-fibre ingadlulisa amabanga amade ngaphandle kokulahlekelwa yisignali. Ukuphazamiseka: I-fibre ayithintwa yi-EMI, okuyi-copper. Ukuphepha: I-fibre kunzima ukuyithinta, ngakho-ke iphephile kakhulu. Izindleko: I-Copper ishibhile kusengaphambili kodwa i-fibre inezindleko eziphansi zesikhathi eside. Ukuqina: I-fibre ibuthakathaka kakhulu ngokomzimba kodwa ingcono ezindaweni ezinzima. Izicelo: Lapho isetshenziswa khona ngayinye.

Linda, kufanele ngihlole ukuthi kukhona yini okunye. O, mhlawumbe ukubambezeleka. I-Fiber ine-latency ephansi, okubalulekile ezinhlelweni zokusebenza zesikhathi sangempela. Futhi, ukudluliselwa kwamandla: I-Copper ingathwala amandla (njenge-PoE), i-fiber ayikwazi. Ngakho-ke amadivayisi asebenzisa i-fiber adinga amandla ahlukile.

Ngidinga ukuhlela lokhu ngokucacile. Mhlawumbe ithebula lingasiza, kodwa ungase ufune incazelo emfushane. Ake ngichaze isigaba ngasinye ngamaphuzu ezinhlamvu, ngiwaqhathanise eceleni.

Izimo ezingaba khona zomsebenzisi: Kungaba umfundi ocwaninga ngephrojekthi, uchwepheshe we-IT onquma ngengqalasizinda, noma umuntu onesithakazelo nge-inthanethi yakhe yasekhaya. Impendulo kufanele itholakale kalula kodwa ibe nemininingwane eyanele kubafundi bezobuchwepheshe.

Qiniseka ukuthi ukhuluma ngezimo ezithile zokusetshenziswa, njenge-fiber yezintambo zangaphansi kolwandle kanye ne-telecom yebanga elide, ithusi lokugijima kwe-Ethernet okufushane. Futhi, thinta izitayela zesikhathi esizayo, njenge-fiber eba yinto evamile njengoba izindleko zincipha.

Kufanele futhi ngigcizelele ukuthi ngikhethe nini ngayinye. Isibonelo, uma isabelomali singumkhawulo futhi ibanga lifushane, ithusi lingaba ngcono. Uma udinga isivinini esikhulu kanye nokuphepha, i-fiber iyindlela engcono.

Hlola noma yimiphi imibono eyiphutha evamile. Isibonelo, abanye bangase bacabange ukuthi i-fiber ibiza kakhulu njalo, kodwa ngokuhamba kwesikhathi, izindleko zokulungisa ziphansi. Futhi, cacisa ukuthi nakuba i-fiber ibuthakathaka, ingcono ezindaweni ezinokuphazamiseka okuningi.

Hlola kabili imininingwane yobuchwepheshe: osayizi abayinhloko, isivinini sokudlulisa, amabanga aphezulu. Isibonelo, amabanga e-single-mode vs multi-mode fiber. Imikhawulo ye-Copper nge-crosstalk kanye ne-EMI.

Kulungile, hlela impendulo ngezihloko ezicacile zesici ngasinye sokuqhathanisa, sebenzisa amaphuzu noma uhlu olunezinombolo ukuze kucace, bese uphetha ngesifinyezo nezincomo ezisekelwe ezimweni zokusetshenziswa. Qiniseka ukuthi kulula ukuyifunda futhi uphendula kokubili izinto zobuchwepheshe nezisebenzayo.

Ikhebula le-Fiber Optic vs. Ikhebula le-Copper: Umehluko Obalulekile

Izintambo ze-fibre optic nezethusi ziyizindlela ezimbili eziyinhloko zokudlulisa idatha, ngayinye inezinzuzo nemikhawulo ehlukile. Nasi ukuqhathanisa okuningiliziwe:

1. I-Transmission Medium

• I-Fiber OpticUkusetshenziswaukushaya kokukhanya(ama-laser/ama-LED) ngokusebenzisa imicu yengilazi/yepulasitiki.

• Ikhebula Lethusi: Ithembele kuizimpawu zikagesingokusebenzisa izintambo zethusi (isb., amabhangqa asontekile, i-coaxial).

2. Isivinini kanye ne-bandwidth

  • Ububanzi bomkhawulo: Cishe ayinamkhawulo ngenxa yemvamisa ephezulu yokukhanya.

• Ikhebula Lethusi:

  • Isivinini: Ngokuvamile kuze kufike ku-10 Gbps(Izintambo ze-Cat 6a/7).

  • Ububanzi bomkhawulo: Kunqunyelwe ukuwohloka kwesignali kumaza aphezulu.

3. Ukulahlekelwa Ibanga Nesignali

• I-Fiber Optic:

  • Ibanga: I-fiber yemodi eyodwa (i-SMF) ingadluliselaAmakhilomitha angaphezu kuka-100ngaphandle kweziphindaphindi.

  • Ukuncipha: Ukulahleka kwesiginali okuncane (~0.2 dB/km).

• Ikhebula Lethusi:

  • Ibanga: Kunqunyelwe ku-Amamitha ayi-100(ye-Ethernet) ngaphambi kokudinga ama-booster.

  • Ukuncipha: Ukulahleka okukhulu kwesignali emabangeni amade ngenxa yokumelana kanye ne-EMI.

4. Ukuphazamiseka Nokuthembeka

• I-Fiber Optic:

  • Ukungavikeleki ku-ukuphazamiseka kwe-electromagnetic (EMI)kanye nokuphazamiseka kwe-radio-frequency (RFI).

  • Akukho ukuxoxisana phakathi kwemicu.

• Ikhebula Lethusi:

  • Ingathinteka yi-EMI/RFI (isb., izintambo zikagesi, ama-motor).

  • Kudinga ukuvikelwa (isb., izintambo ze-STP) ukuze kuncishiswe ukuphazamiseka.

5. Ukuphepha

• I-Fiber Optic:

  • Kunzima kakhulu ukuthepha ngaphandle kokuphazamisa isignali yokukhanya (etholakalayo).

  • Kulungele izindawo eziphephile (isib., ezempi, ebhange).

• Ikhebula Lethusi:

  • Kulula ukuthepha (ukulalela nge-electromagnetic).

  • Kudinga ukubethela (isb., i-TLS) ukuze kutholakale idatha ephephile.

6. Izindleko

• I-Fiber Optic:

  • Izindleko eziphezulu kusengaphambili(ukufakwa, ama-transceivers, imishini yokuxhumanisa).

  • Izindleko eziphansi zesikhathi eside (ukuqina, ukulungiswa okuncane).

• Ikhebula Lethusi:

  • Ukusetha kokuqala okushibhile(kutholakala kabanzi, ukuqeda okulula).

  • Ukugcinwa okuphezulu ngokuhamba kwesikhathi (ukuwohloka kwesignali, ukuvikelwa kwe-EMI).

7. Ukuqina kanye Nemvelo

• I-Fiber Optic:

  • Ibuthakathakaingilazi engaphakathi (idinga ukuphathwa ngokucophelela).

  • Ayimelani nokushintshashintsha kwezinga lokushisa, umswakama, kanye nokugqwala.

• Ikhebula Lethusi:

  • Okuningiukuqina ngokomzimbakodwa kulula ukugqwala (isib., ezindaweni ezinomswakama).

  • Inzima futhi ikhulu kunefayibha.

8. Izicelo

• I-Fiber Optic:

  • Ukuxhumana nge-telecom okude (izintambo ezingaphansi kolwandle, izintambo ze-ISP).

  • Izikhungo zedatha, amanethiwekhi e-5G, izithombe zezokwelapha, kanye nezinhlelo zempi.

• Ikhebula Lethusi:

  • I-Ethernet yebanga elifushane (ama-LAN, amahhovisi, amakhaya).

  • Amandla phezu kwamadivayisi e-Ethernet (PoE) (isib., amakhamera e-IP, amafoni e-VoIP).

9. Ukubambezeleka

• I-Fiber Optic: Ukubambezeleka okuphansi (~30% ngokushesha kunethusi) ngenxa yesivinini sokukhanya.

• Ikhebula Lethusi: Ukubambezeleka okuphezulu, ikakhulukazi emabangeni amade.

10. Ukudluliselwa Kwamandla

• I-Fiber Optic: Ayikwazi ukudlulisa amandla kagesi (idinga amandla ahlukile kumadivayisi).

• Ikhebula Lethusi: UkusekelaAmandla phezu kwe-Ethernet (i-PoE), ukuletha idatha namandla ngasikhathi sinye.

Ukukhetha Nini?

• I-Fiber Optic:

  • Izidingo zesivinini esikhulu, zebanga elide (isib., ama-ISP, izikhungo zedatha).

  • Izindawo ezine-EMI enzima (amafektri, izibhedlela).

  • Izidingo zokuphepha ezibalulekile.

• Ikhebula Lethusi:

  • Ukuhlela okunesabelomali esincane, okufushane (isib. amanethiwekhi asekhaya).

  • Izinhlelo zokusebenza ze-PoE (amakhamera okuphepha, amadivayisi e-IoT).

  • Izinhlelo zakudala zisasebenzisa ingqalasizinda yethusi.

Amathrendi Esikhathi Esizayo

• Ukwamukelwa kwe-fibre optic kuyanda ngenxa yezidingo ze-5G, i-cloud computing, kanye ne-IoT.

• I-Copper isabalulekile ekusetshenzisweni kwe-PoE kanye nokusetshenziswa okungabizi kakhulu.

Isiphetho: Izintambo ze-fibre optic zidlula ithusi ngesivinini, ibanga, kanye nokuthembeka kodwa zinezindleko zokuqala eziphakeme. Ithusi lihlala lisebenza kumasethingi afushane, anesabelomali esiphansi, noma ancike ku-PoE. Ukukhetha kuncike ezidingweni zakho ezithile zesivinini, ukuphepha, kanye nokukhula.
