Network Cable

Network Cable isvikiro inotumira ruzivo kubva kune imwe network network (senge komputa) kuenda kune imwe network network. Ndicho chinhu chakakosha chetiweki. Mune yedu yakajairika yenzvimbo network, iyo network tambo inoshandiswa zvakare ndeyemhando dzakasiyana. Mumamiriro ezvinhu akajairwa, yakajairika LAN kazhinji haishandise akasiyana marudzi akasiyana etiweki tambo kubatanidza network zvishandiso. Mune network yakakura kana yakakura nzvimbo network, mhando dzakasiyana dzetiweki tambo dzinoshandiswa kubatanidza mhando dzakasiyana dzemambure pamwe chete.Ipi network tambo yekushandisa inofanira kusarudzwa zvinoenderana netology topology, network yemaitiro zviyero uye kukurumidza kwekutumira.Inotumira masaini muchimiro yechiedza pulses uye ine optical fibers yakagadzirwa negirazi kana transparent plastic.Pazasi pane imwe sumo nezveNetwork Cable.

Sechikamu chakakosha chehunyanzvi hwekutaurirana hwazvino, inoita basa rakakosha rekufambiswa kwedata. Kubva pamatambo enhare ekutanga kusvika kune anhasi mafiber optical anotsigira kukurumidza kufambisa data, mhando uye matekinoroji etambo dzenetiweki zvakave nekushanduka kukuru.

Tambo yetiweki ine mapeya mana ewaya uye masere cores. Nheyo yega yega ine mutsauko wemavara uye inoshandiswa pakufambisa data. Inogona kushandiswa kune zvakasiyana-siyana zvakasiyana-siyana zvezviitiko mune yakasanganiswa wiring system.

1）Yakakamurwa nechiitiko chekushandisa: inogona kukamurwa kuita tambo dzemukati uye tambo dzekunze. Tambo dzemukati (indoor cables) zvinoreva tambo dzinoshandiswa kutumira masaini mukati mezvivakwa, setambo dzenetiweki, tambo dzenhare, netambo dzeterevhizheni. Tambo dzekunze dzinoreva tambo dzinoshandiswa kutumira masaini munzvimbo dzekunze, senge tambo dzemaziso uye coaxial tambo.

2）Classified bychimiro: inogona kukamurwa kuita isina kuvharidzirwa yakamonyoroka peya uye yakadzivirirwa yakamonyoroka peya. Unshielded twisted pair inoreva mbiri yakamonyoroka isina yekunze simbi inodzivirira layer, inowanzo shandiswa kufambisa masaini eanalogi nekumhanya kwakaderera. Shielded twisted pair inoreva peya yakamonyoroka ine yekunze simbi inodzivirira layer, iyo inowanzo shandiswa kukurumidza-kumhanya kufambisa kwemasaini edhijitari uye ine yakanaka anti-kukanganisa kuita.

3）Yakakamurwa nechiratidziro: Iyo interface inogona kuiswa muRJ-11, RJ-45, uye SC interfaces. Chiteshi cheRJ-11 chinoshandiswa kubatanidza mitsara yeanalogi yefoni, chiteshi cheRJ-45 chinoshandiswa kubatanidza tambo dzeEthernet, uye SC port inoshandiswa kubatanidza optical fibers.

4）Zvino tambo yakawanda yetiweki inogona kukamurwa kuva marudzi mashanu etiweki tambo (CAT.5), (CAT.5E), (CAT.6), (CAT.6A), (CAT.7).

a.Chikamu 5, Katsi5

Kushandiswa: Chikamu 5 tambo ndiyo yakajairwa tambo yekukurumidza Ethernet (100Mbps) uye inoshandiswa zvakanyanya mudzimba uye madiki bhizinesi network.

Zvimiro: Yekufambisa frequency: 100MHz.

Data Rate: Yakagadzirirwa 10/100Mbps Ethernet.

Chishandiso: Inokodzera kuwanikwa kweInternet, kugovera faira, uye masevhisi eVoIP. Nekuvandudzwa kwehunyanzvi, zvishoma nezvishoma yakatsiviwa neCat5e.

b.Chikamu 5e, Cat5e

Kushandiswa: Super Mitsara Mishanu yakagadziridzwa pahwaro hwemitsara mishanu, uye inogona kutsigira zvakasimba Gigabit Ethernet (1000Mbps).

Zvimiro: Yekufambisa frequency: 100MHz

Nhamba yedata: 10/100/1000Mbps.

Chishandiso: Sarudzo yemazuva ano yeimba yemazuva ano, hofisi uye madiki uye epakati bhizinesi network, inotsigira yakakwirira-tsanangudzo vhidhiyo, mitambo yepamhepo uye yakawanda yekufambisa data.

c. Chikamu 6, Katsi6

Kushandiswa: Mitsetse yeKirasi mitanhatu yakagadzirirwa kusangana nezvinodiwa zvekumhanya kwenetiweki yepamusoro, kunyanya kune bhizinesi-kirasi network uye nzvimbo dzedata.

Chikumbiro: Inokodzera nharaunda dzine zvakakwirira zvinodikanwa panetiweki kutapurirana kumhanya uye kugadzikana, senge bhizinesi remukati network uye data nzvimbo.

d.Chikamu 6a, Cat6a

Kushandiswa: Super Kirasi 6 Mutsetse ishanduro yakakwidziridzwa yeKirasi 6 mutsara, ichipa zvirinani crosstalk control uye kudzivirira maitiro, akagadzirirwa kukurumidza-kumhanya kufambisa data.

Features: Transmission frequency: kusvika 500MHz.

Nhamba yedata: Tsigiro yakagadzikana ye10Gbps kutapurirana, uye kureba kusvika ku100 metres.

Chikumbiro: Inokodzera kutariswa kwepamusoro-bandwidth application mune ramangwana, senge hombe data data, cloud computing zvivakwa, uye yakakwirira-kumhanya network switching centers.

Kubva pane yakapfava yakamonyoroka dhizaini kusvika pakuiswa kwedziviriro maseru uye optimization yetambo dhizaini uye zvinhu, kuvandudzwa kwetiweki tambo tekinoroji ine chinangwa chekuenderera mberi nekuvandudza kukurumidza kwekufambisa data, kuderedza kukanganiswa kwechiratidzo, uye kuwedzera kureba kwekutapurirana. Nekuenderera mberi kwekuvandudzwa kwekuda kwevashandisi kumhanya kwetiweki uye mhando, network tambo tekinoroji yachinja zvishoma nezvishoma kubva kune yekutanga analogi chiratidzo chekufambisa kuti itsigire yekumhanyisa kutaurirana kwedhijitari, uye kutangwa kwechizvarwa chimwe nechimwe chetambo dzetiweki chinhu chitsva uye kupfuura yapfuura. generation of technology Nhamba inotevera inoratidza kuzivikanwa kweCAT.6.

Iyo RJ45 yekubatanidza yetiweki tambo inogona kuve yakatwasuka-kuburikidza netambo kana crossover tambo. Kuburikidza nemutsetse ndiyo tambo magumo ese ari T568A kana ese ari T568B chiyero; Nzira yekuyambuka mitsara ndeye kushandisa T568A chiyero kune imwe mugumo uye T568B yakajairwa kune imwe mugumo. Iye zvino network network network ports inotsigira adaptive, kuburikidza nemutsara uye muchinjiko mutsetse unogona kushandiswa.

T568A kutevedzana kwewaya: ① ​​chena&girinhi ② girini ③ chena&orenji ④ bhuruu ⑤ chena & bhuruu ⑥ orenji ⑦ chena & shava ⑧ brown

T568B waya kutevedzana: ① chena & orenji ② orenji ③ chena & yegirinhi ④ yebhuruu ⑤ yebhuruu & chena ⑥ yegirini ⑦ chena & shava ⑧ brown

Theino mhando dzakawanda dzetambo dzemambure, uye panogona kuva nemhando dzakasiyana maererano nenzira dzakasiyana dzekuisa. Sarudza tambo dzetiweki zvichienderana nemamiriro chaiwo ekushandisa uye zvinodiwa.

Senheyo yekona yekukurukurirana kwenetiweki, kukudziridzwa uye kushandiswa kwetambo yetiweki kwakabatana zvakananga nekubudirira uye kunaka kwenharaunda yeruzivo. Nekuenderera mberi kwekufambira mberi kwetekinoroji uye kusiyanisa kwezvido zvemusika, kusarudza iyo chaiyo mhando yetiweki tambo yave kiyi yekuvaka inoshanda uye yakavimbika network. Kunzwisisa shanduko yetekinoroji, mamiriro ekushandisa, uye marongero ekusarudza ematambo etiweki kwakakosha kwete chete kune mainjiniya etiweki, asiwo kune vashandisiwo zvavo kuti vavandudze ruzivo rwavo rwetiweki. Kutarisana nezvinodiwa zvepamusoro zvenguva yemberi yekukurukurirana kwenetiweki, kuramba tichiteerera kune kufambira mberi kutsva kwetiweki tambo tekinoroji ichava nzira yakakosha yekuti isu tibatanidze kune yakafara dhijitari nyika.
