Iindaba

(1) Ukudibanisa: Ukufakelwa kweentambo zeofisi kufuneka kuhlangabezane neemfuno zothumelo lweesignali ezahlukeneyo ze-analog okanye zedijithali, kwaye kudityaniswe zonke iilwimi, idatha, umfanekiso, kunye neentambo zezixhobo zokubeka esweni zibe yinkqubo eqhelekileyo yentambo ze-E...

(1) Ubhedu olucocekileyo. Ubhedu olucocekileyo yeyona ntambo yenethiwekhi ilungileyo neyomgangatho ophezulu. Ifanelekile kwizixhobo zombane zePoE kwaye inokumelana okuncinci ukuthintela ukulahleka kombane ngexesha lokudluliselwa. Olu hlobo lwentambo yenethiwekhi yeyona ntambo ilungileyo...

1. Jonga Umbala: Okokuqala, vula ijakethi engaphandle yentambo yenethiwekhi uze uyivavanye. Ngoku ungabona iingcingo zenethiwekhi zidibene kwaye uzithelekise ngononophelo. Ukuba iingcingo eziluhlaza nezimhlophe kunye neengcingo eziluhlaza nezimhlophe...

I-GY--Intambo ye-fiber optic yangaphandle i-GJ--Intambo ye-optical yangaphakathi i-MG--Intambo ye-optical yomgodi wamalahle II. Iintlobo zezinto eziqinisayo (akukho modeli)--Ilungu lokuqinisa isinyithi F--Ilungu lokuqinisa elingelona lesinyithi III. Iimpawu zesakhiwo...

Izinto eziphambili ezibangela ukuncitshiswa kwefayibha zezi: izinto ezingaphakathi, ukugoba, ukuphuma, ukungcola, ukungabikho kokufana, kunye nokudibanisa. 1. Ingaphakathi: Oku kukulahleka okungokwemvelo kwefayibha, kuquka: Ukusasazeka kweRayleigh, ukufunxwa...

Inzuzo 1. Umthamo ophezulu wokumelana neemeko zemozulu eziqatha (imimoya enamandla, isichotho, njl.njl.). 2. Ukuguquguquka kobushushu obuqinileyo kunye nomlinganiselo omncinci wokwandiswa okuthe tye ukuhlangabezana neemfuno zeemeko ezinzima...

Ngokusekelwe kumacandelo kunye nezakhiwo ezahlukeneyo ze-OPGW, i-OPGW yahlulwe ngolu hlobo lulandelayo. 2.1 Ngokwezinto ezikwityhubhu yokukhusela yeyunithi yokukhanya, uhlobo lwesakhiwo se-OPGW lwahlulwe lwaba yityhubhu ye-OPGW yentsimbi engagqwaliyo kwaye...

1. Iintambo ze-aerial fiber optic zisetyenziswa kakhulu kwimigca yesibini yesiqu kunye nemigca yentambo ye-fiber optic engaphantsi komhlaba, kwaye zifanelekile kwiindawo ezinemihlaba ethe tyaba kunye nokuguquguquka okuncinci kwe-voltage. 2. Kukho iindlela ezimbini zokumiswa...

Ifayibha yemowudi enye (ifayibha yemowudi enye): ukukhanya kungena kwifayibha kwi-engile ethile yokwenzeka kwayo, kwaye ukukhutshwa okupheleleyo kwenzeka phakathi kwefayibha kunye ne-cladding. Xa ububanzi buncinci, ukukhanya kuvunyelwe kuphela ukuba kudlule kwicala elinye...

Izinto ezahlukeneyo: Uninzi lweentambo ze-fiber optic zenziwe ngefayibha yeglasi, ngelixa iintambo zenethiwekhi zenziwe ngeentambo zobhedu. Izantya ezahlukeneyo zokudlulisela: Iintambo zeCandelo lesi-7 ezilungileyo kwiintambo zenethiwekhi...

Uvavanyo lweSiteshi: Le nto idla ngokusetyenziswa njengento yovavanyo lwe-network patch. Iintambo zenethiwekhi ezivavanyiweyo zinokuhlangabezana neemfuno ezininzi zenethiwekhi kwaye zifanelekile kwiinethiwekhi zamashishini amancinci kunye noqhagamshelo lweentambo zasekhaya zokuhambisa umgama omfutshane. Uvavanyo lwekhonkco: Inga...

1. Chaza ngokufutshane ukwakheka kweefayibha ze-optical. A: Ifayibha ye-optical inamacandelo amabini asisiseko: umbindi kunye ne-cladding, zombini zenziwe ngezinto ezibonakalayo ezibonakalayo. 2. Zeziphi iiparameter ezisisiseko ezichaza...
