Iyo yakajairwa yenzvimbo network mune yayo yazvino (avhareji) fomu yakazogadzirwa makore mazhinji apfuura, uko kukura kwayo kwakamira.
Kune rimwe divi, akanakisa muvengi wezvakanaka, kune rumwe rutivi, kumira hakuna kunaka kwazvo. Uyezve, pakunyatsoongorora, hofisi yemazuva ano network, iyo inokubvumira kuita anenge ese mabasa ehofisi yenguva dzose, inogona kuvakwa yakachipa uye nekukurumidza kupfuura zvinotendwa kazhinji, uye mavakirwo ayo anozove akareruka uye akawedzera scalable. Musanditenda? Ngatiedzei kuzvinzwisisa. Uye ngatitangei neicho chinonzi chakakodzera kuiswa kwetiweki.
Chii chinonzi SCS?
Chero yakarongeka cabling system (SCS) sechinhu chekupedzisira cheinjiniya masisitimu anoitwa mumatanho akati wandei:
- design;
- chaizvoizvo, kuiswa kwetambo zvivakoti;
- kuiswa kwenzvimbo dzekuwana;
- kuiswa kwekuchinja mapoinzi;
- kutumwa mabasa.
Kugadzira
Chero basa guru, kana uchida kuzviita nemazvo, rinotanga nekugadzirira. Kune SCS, kugadzirira kwakadaro kugadzirwa. Panguva ino ndipo painotariswa kuti mangani mabasa anofanirwa kupihwa, mangani madoko anofanirwa kuwanikwa, uye ndeapi hunyanzvi hunoda kuiswa pasi. Panguva ino, zvinofanirwa kutungamirwa nezviyero (ISO/IEC 11801, EN 50173, ANSI/TIA/EIA-568-A). Muchokwadi, iri padanho rino kuti muganhu wekugona kweiyo yakagadzirwa network inotarwa.
Cable infrastructure
Panguva ino, mitsara yese yetambo yakaiswa kuti ive nechokwadi chekufambiswa kwedata pamusoro penetiweki yemuno. Makiromita etambo yemhangura yakamonyoroka zviri zviviri. Mazana emakirogiramu emhangura. Kudiwa kwekuisa tambo mabhokisi uye trays - pasina ivo, kuvakwa kweiyo yakarongeka tambo system hazvigoneke.
Nzvimbo dzekuwana
Kupa nzvimbo dzebasa kuwana kune network, nzvimbo dzekuwana dzakaiswa. Kutungamirirwa nemusimboti wekuregererwa (imwe yeakanyanya kukosha mukuvakwa kweSCS), mapoinzi akadaro akaiswa muhuwandu hunodarika huwandu hunodiwa. Nekufananidza nemagetsi emagetsi: zvakanyanya zvigadziko zviripo, zvakanyanya kushanduka iwe unogona kushandisa nzvimbo iyo network yakadaro iripo.
Kushandura mapoinzi, kutumwa
Tevere, iyo huru uye, senge sarudzo, yepakati switching point inoiswa. Racks / telecom makabati anoiswa, tambo uye zviteshi zvakamisikidzwa, zvinongedzo zvinogadzirwa mukati meiyo consolidation point uye mune crossover node. Iyo switching log inoumbwa, iyo inozogadziridzwa mukati mehupenyu hwese hwetambo system.
Kana matanho ese ekuisa apera, iyo system yese inoedzwa. Cables dzakabatana kune inoshanda network michina, uye network inomiswa. Kuenderana neiyo frequency bandwidth (yekufambisa kumhanya) yakaziviswa kune yakapihwa SCS inotariswa, iyo yakagadzirirwa nzvimbo dzekuwana dzinodanwa, uye mamwe ese ma paramita akakosha pakushanda kweSCS anotariswa. Zvose zvakakanganiswa zvinoonekwa zvinobviswa. Chete mushure meizvi, network inotamirwa kune mutengi.
Iyo yepakati yepakati yekufambisa ruzivo yakagadzirira. Chii chinotevera?
Chii "chinogara" muSCS?
Pakutanga, data kubva kune akasiyana masisitimu, yakavharwa kune yavo tekinoroji uye mapuroteni, aifambiswa pamusoro petambo yemagetsi network yemuno. Asi tekinoroji zoo yagara ichiwedzerwa ne zero. Uye ikozvino munharaunda yenzvimbo pane, pamwe, chete Ethernet yasara. Nharembozha, vhidhiyo kubva kumakamera ekutarisa, maaramu emoto, masisitimu ekuchengetedza, data yemamita ekushandisa, masystem ekudzora uye smart intercom, pakupedzisira - zvese izvi zvino zvinoenda pamusoro peEthernet.
Smart intercom, yekupinda yekudzora system uye remote control mudziyo
Isu tinogadzirisa zvivakwa
Uye mubvunzo unomuka: nekuenderera mberi kwekuvandudza tekinoroji, isu tichiri kuda here zvikamu zvese zvechinyakare SCS?
Hardware uye software switching
Yave nguva yekubvuma chinhu chiri pachena: Hardware switching pamwero wemuchinjiko-wekubatanidza uye tambo dzechigamba dzakapfuura kubatsira kwayo. Zvese zvagara zvichiitwa pachishandiswa VLAN ports, uye vatariri vanoronga kuburikidza newaya mumawadhiropu pese painenge paine shanduko mumambure etiweki ndiko kukanda kumashure. Yave nguva yekutora nhanho inotevera uye kungosiya michinjikwa nema patchcords.
Uye zvinoita sechinhu chidiki, asi kana iwe ukafunga nezvazvo, pachava nezvimwe zvikomborero kubva padanho iri pane kubva pakuchinja kune tambo yechikamu chinotevera. Zvitongere wega:
- Hunhu hweiyo yemuviri chiratidzo chekufambisa svikiro huchawedzera.
- Kuvimbika kuchawedzera, nekuti isu tiri kubvisa maviri kubva matatu emakanika maconta kubva kuhurongwa (!).
- Nekuda kweizvozvo, iyo chiratidzo chekutumira huwandu huchawedzera. Hazvina kukosha, asi zvakadaro.
- Pachangoerekana pave nenzvimbo mumawadhiropu ako. Uye, nenzira, kuchave nekuwanda kwakawanda kurongeka ikoko. Uye izvi zviri kutochengetedza mari.
- Mutengo wemidziyo yakabviswa idiki, asi kana iwe ukafunga nezve chiyero chese chekugadzirisa, huwandu hwakanaka hwekuchengetedza hunogonawo kuunganidzwa.
- Kana pasina muchinjiko-wekubatanidza, unogona crimp mitsara yemutengi zvakananga pasi peRJ-45.
Chii chinoitika? Isu takarerutsa network, tikaita kuti ive yakachipa, uye panguva imwechete yakava shoma uye inogoneka. Zvose zvakanakira!
Kana kuti zvimwe, zvino, kanda chimwe chinhu kure? π
Optical fiber panzvimbo yemhangura core
Sei tichida makiromita etambo dzakamonyoroka dzepairi apo huwandu hwese hweruzivo hunofamba nemusumbu gobvu rewaya dzemhangura hunogona kufambiswa zviri nyore kuburikidza neoptical fiber? Ngatiisei 8-port switch muhofisi ine optical uplink uye, semuenzaniso, tsigiro yePoE. Kubva pawadhiropu kuenda kuhofisi pane imwe fiber optic core. Kubva pakushandura kune vatengi - copper wiring. Panguva imwecheteyo, mafoni eIP kana makamera ekutarisa anogona kupihwa simba nekukurumidza.
Panguva imwecheteyo, kwete chete kuwanda kwetambo yemhangura mumatireyi akanaka ereti inobviswa, asiwo mari inodiwa pakuisa kubwinya uku, kwechinyakare kweSCS, inoponeswa.
Ichokwadi, chirongwa chakadaro chinopokana nepfungwa yekuiswa "kwazvo" kwemidziyo munzvimbo imwechete, uye kuchengetedza patambo uye multiport switch ine copper ports ichashandiswa pakutenga diki switch nePoE uye optics.
Kudivi revatengi
Iyo mutengi-parutivi tambo yakadzokera kunguva iyo isina waya tekinoroji yaitaridzika setoyi pane chaiyo yekushandisa chishandiso. Mazuva ano "wireless" ichapa zvinomhanya zviri nyore pane izvo zvinopihwa netambo, asi zvinokutendera kuti usunungure komputa yako kubva kune yakagadziriswa kubatana. Hongu, mafungu emhepo haasi rubber, uye hazvizoitike kuti rizadze nekusingaperi nematanho, asi, chekutanga, chinhambwe kubva kune mutengi kusvika kunzvimbo yekuwana chinogona kunge chiri chidiki kwazvo (zvinodiwa zvehofisi zvinobvumira izvi), uye chechipiri, ipapo. dzatova mhando itsva tekinoroji anoshandisa semuenzaniso, optical radiation (somuenzaniso, inonzi Li-Fi).
Iine huwandu hunodiwa mukati me5-10 metres, yakakwana kubatanidza vashandisi 2-5, nzvimbo yekupinda inogona kutsigira zvizere gigabit chiteshi, inodhura zvishoma uye inovimbika zvachose. Izvi zvichachengetedza mushandisi wekupedzisira kubva kune waya.

Munguva pfupi iri kutevera, mukana wakadaro uchapihwa nemidziyo inoshanda mumillimeter wave (802.11ad/ay), asi parizvino, kunyangwe ichimhanya yakaderera, asi ichiri kushomeka kune vashandi vemuhofisi, izvi zvinogona kuitwa zvichibva pa802.11. ac standard.
Ichokwadi, munyaya iyi nzira yekubatanidza michina yakadai se IP mafoni kana vhidhiyo makamera inoshanduka. Chekutanga, ivo vanofanirwa kupihwa simba rakasiyana kuburikidza nemagetsi. Chechipiri, zvishandiso izvi zvinofanirwa kutsigira Wi-Fi. Nekudaro, hapana anorambidza kusiya imwe nhamba yemhangura zviteshi panzvimbo yekuwana kekutanga. Zvirinani zvekudzokera kumashure kana zvinodiwa zvisingatarisirwe.

Nhanho inotevera ine musoro, handiti?
Ngatirege kugumira ipapo. Ngatibatanidzei nzvimbo dzekupinda netambo yefiber optic ine bandwidth, toti, gumi gigabits. Uye ngatikanganwe nezvechinyakare SCS sekurota kwakaipa.
Chirongwa chinova nyore uye chinoyevedza.
Panzvimbo pemirwi yemakabati nematireyi akazadzwa netambo yemhangura, tinoisa diki kabati umo switch ine optical "madhizeni" "inorarama" kune yega yega vashandisi 4-8, uye isu tinowedzera iyo fiber kuti isvike nzvimbo. Kana zvichidikanwa, kune midziyo yekare iwe unogona kuisa mamwe "mhangura" madoko pano - haazokanganise hukuru hwezvivakwa munzira chero ipi zvayo.
