Itekhnoloji yeTekhnoloji ye-Ethernet (PoE) itshitshisile indlela esibonisa ngayo izixhobo zenethiwekhi ngokuvumela amaNqaku oMandla kunye nedatha ukuba idluliselwe ngaphezulu kwe-Ethernet ye-Ethernet. Nangona kunjalo, uninzi lwabasebenzisi luyazibuza ukuba lelona nqanaba liphezulu lokuhambisa i-poe. Ukuqonda izinto eziphembelela le mgama kubalulekile ukuze kucwangciswe inethiwekhi kunye nokubulawa.

Yintoni egqiba umgama ophezulu we-poe?

Into ebalulekileyo ekuqinisekiseni umgama ophezulu we-poe ngumgangatho kunye nohlobo lwentambo ye-wit ejijekileyo esetyenzisiweyo. Imigangatho eqhelekileyo yokufaka i-cabling ibandakanya:

I-Shanghai-Aipu-Aton-elektroniki-I-elektroniki-i-co-ltd-

ICandelo le-5 (ikati 5)

Ixhasa isantya ukuya kwi-100 mbps

Udidi 5e (ikati 5e)

Inguqulelo ephuculweyo yentsebenzo engcono, ikwaxhasa i-100 MBPS.

ICandelo le-6 (ikati 6)

Inokujongana nezantya kwi-1 GBPS.

Nokuba loluphi uhlobo lwentambo, imigangatho yeshishini yaseka umgama ophumeleleyo we-100 yeemitha (ezingama-328 iinyawo) zonxibelelwano lwedatha ngaphezulu kweentambo ze-Ethernet. Lo mda ubalulekile ekugcineni ingqibelelo kunye nokuqinisekisa unxibelelwano oluthembekileyo.

Isayensi emva komda we-100 yeemitha

Xa udlulisa imiqondiso, iintambo ezimbini ezijijekileyo ngamava amava kwaye amandla, onokukhokelela ekuphelisweni kwesiginali. Njengomqondiso ohamba ngentambo, inokufumana:

I-Attinatus:

Ukuphulukana namandla eMiqondiso ngaphezulu komgama.

Uphazanyiso:

Utshintsho kumqondiso wokubonisa umqondiso, ukuphembelela ukuthembeka kwedatha.

Nje ukuba umgangatho womqondiso uyancipha ngaphaya kwemilinganiselo eyamkelekileyo, ichaphazela amaqondo othumelwano asebenzayo kwaye unokukhokelela kwilahleko yedatha okanye iimpazamo zepakethi.

Ukubala umgama ohambisayo

Kwi-100base-tx, esebenza kwii-100 MBPs, ixesha lokudlulisela idatha enye, eyaziwa ngokuba "lixesha elincinci," libaliwe ngolu hlobo lulandelayo:

[\ Itekisi {i-{} = \ frac {1} {100, \ umbhalo {MBPs}}

Le ndlela yokuhambisa isebenzisa i-CSMA / CD (i-CD Nangona kunjalo, ukuba ubude bentambo bungaphezulu kwe-100 yeemitha, amathuba okufumana i-collinas kuyadinisa, ukuthoba ilahleko yokulahleka kwedatha.

Kubalulekile ukuba uqaphele ukuba ngelixa ubude obukhulu bubekwe kwiimitha ezili-100, iimeko ezithile zinokuvumela ukuba kubekho ezinye. Isantya esisezantsi, umzekelo, sinokuhlala sinokuhamba imigama enokusetyenziswa ukuya kuthi ga kwi-150-200 yeemitha, kuxhomekeke kumgangatho womgangatho wentambo kunye neemeko zenethiwekhi.

Iingcebiso zobude beCable

Kwindawo yokufakelwa okwenyani emhlabeni, ukubambelela ngokungqongqo kumda we-100 yeemitha kuyacetyiswa. Nangona kunjalo, uninzi lweengcali zenethiwekhi zicebisa ukugcina umgama weemitha ezingama-80 ukuya kwezingama-90 ukuqinisekisa ukuthembeka kunye nokunciphisa nayiphi na imiba esemgangathweni enokubakho. Lo mmandla wokhuseleko unceda ekuhlaleni umahluko kumgangatho wentambo kunye neemeko zofakelo.

Ngelixa iicuba ezisemgangathweni eziphezulu ngamanye amaxesha zinokukhululeka kumda we-100 yeemitha ngaphandle kwemicimbi kwangoko, le ndlela ayicetyiswa. Iingxaki ezinokubakho zinokubonakalisa ngokuhamba kwexesha, ezikhokelela ekuphazamiseni okubalulekileyo kwenethiwekhi okanye ukusebenza ngokwaneleyo emva kokuphuculwa.

Ukuqukumbela

Ukushwankathela, owona mgama ugqithiso lweTekhnoloji ye-POE ichukunyiswe ludidi lweentambo ezimbini ezijijekileyo kunye neentsilelo zomzimba zosulelo lomqondiso. Imida ye-100 yeemitha isekwa ukunceda ukugcina ukuthembeka kwedatha kunye nokuthembeka. Ngokulandela iinkqubo zokufakelwa kunye nokuqonda imigaqo-siseko esisiseko sosulelo, iingcali zenethiwekhi zinokuqinisekisa ukusebenza kweomeleleyo kunye nenethiwekhi efanelekileyo.
