Ungakhetha kanjani ikhebula elifanele le-fiber optical yasendlini?

Cacisa injongo yezintambo ezibonakalayo

Izintambo zangaphakathi zangaphakathi zingahlukaniswa zibe izinhlobo ezilandelayo ngokuya ngesakhiwo sazo, ukusebenza kanye nezimo zohlelo lokusebenza:

1. Izintambo ezibonakalayo ze-trunk zangaphakathi zisetshenziselwa ukunikeza iziteshi zokuxhumana phakathi kwangaphakathi nangaphandle kwezakhiwo futhi zixhume amakamelo okufaka izintambo esitezi ngasinye.

Inenani elikhulu lama-cores, isakhiwo esiqinile, ukumelana okuhle kwe-tensile kanye nokumelana nokucindezela.

2. Izintambo zokukhanya kwangaphakathi zokufaka izintambo zasendlini zixhuma amagumbi okufaka izintambo esitezi ngasinye nendawo yokusebenza ukuze kuhlinzekwe uxhumo lwenethiwekhi lwemishini yokugcina.

Inenombolo encane yama-cores kanye nesakhiwo esihlangene, esifanele izindawo ezincane, futhi sinokuguquguquka okuhle nokumelana nokugoba.

3. Izintambo ezibonakalayo ezidluliswayo zasendlini zisetshenziselwa ukunweba ibanga lokuxhumana futhi zingaxhuma izingxenye ezimbili zezintambo ezibonakalayo.

Inokusebenza okuzinzile nokulahlekelwa okuphansi, okungaqinisekisa ukudluliswa kwezimpawu ezikude.

4. Izintambo ezibonakalayo eziqondile zisetshenziswa emapayipini emigodini eqondile phakathi kwaphansi.

Khetha amakhebuli aphakamisa amehlo amile angamelana ne-deadweight enkulu namandla aqinile ukuze uqinisekise ukusebenza okuzinzile kwezintambo ezibonakalayo.

5. Ngezintambo ezikhethekile ze-optical ezindaweni ezinokulimala kwamagundane, izintambo ezibonakalayo ezivikela amagundane zikhethwa ukuvikela izintambo ezibonakalayo emonakalweni.

Khetha uhlobo lwefayibha

I-fiber yemodi eyodwa: ilungele ukudluliswa kwebanga elide, ifanele amakamelo ekhompiyutha ebhizinisi, ukwakheka kwenethiwekhi yesikhungo sedatha.

I-Multimode fiber: ilungele izimo zokudlulisa amabanga amafushane, ukuhlangabezana nezidingo zamanethiwekhi asekhaya kanye nezimo ezincane zenethiwekhi.

Ukuqonda izinga lokudlulisela

Amazinga okudlulisela amakhebuli okubona asetshenziswa ngokuvamile aboniswa kuthebula elilandelayo

I-fiber optical yemodi eyodwa: isekela amazinga okudlulisela e-10Gbps kuya ku-100Gbps nangaphezulu, futhi isekela ukudluliswa kwebanga elide. Izimo ezisebenzayo: amagumbi amakhulu ekhompiyutha, amanethiwekhi amathambo aphansi, njll.

I-Multimode optical fiber: evame ukusetshenziswa i-OM3/OM4 noma ngaphezulu, isekela i-40Gbps/100Gbps (imishini ethize edingekayo), inekhono eliqinile lokulwa nokuphazamiseka, futhi ifanelekela izimo zezintambo eziphakeme kakhulu.

Khetha impahla ye-sheath

1. I-PVC sheath: ifanele izintambo ezijwayelekile zasendlini, ezingabizi kakhulu, ezinzile futhi ezihlala isikhathi eside.

2. I-LSZH ephansi ye-halogen-free sheath: i-halogen-free retardant ye-flame retardant ephansi, ingasetshenziswa emakamelweni ekhompyutha aphephile, izikole nezinye izimo.

Ngokuvamile, isikhumba sangaphandle somkhiqizo sizoba nezimpawu ezicacile, ezimakwe ngolwazi olufana nohlobo lwefayibha kanye nemininingwane yesikhumba yangaphandle.

Nquma inani le-fiber cores

Thola inani lama-fiber cores ngokwezidingo zangempela. Ukusetshenziswa kwasekhaya, ama-cores angu-2 noma angu-4 angakhethwa, futhi izinhlelo zokusebenza ezisezingeni lebhizinisi ngokuvamile zidinga ngaphezu kwama-cores angu-8. Uma ama-cores engeziwe, amandla okudlulisela ekhebula le-optical makhulu, kodwa izindleko ziphezulu. Imajini engu-30% kufanele igcinelwe inombolo yangempela yama-cores asetshenziswa ukugwema ubunzima ekwandiseni kamuva.
