Fiber-optic ikhebula - uhlobo ehlukile cabling abezindaba

Kuze kube manje, fibre optic ikhebula uhlobo ehlukile imvelo ikhebula. Njengoba isici esiyisisekelo kuphuma ingilazi, okuvumela ukuba adlulisele ulwazi olude ngaphandle kokulahleka abalulekile isivinini. Transmission kulokhu eyenziwa hhayi isignali kagesi, futhi sibonga i-pulse ukukhanya, esiza ukunikeza okusezingeni eliphezulu umsindo ukungatheleleki ukuphepha kolwazi ngocansi. Nokho, ukufakwa fibre optic ikhebula kudala ubunzima obuthile ngoba idinga phakathi kokufakwa nezixhumi Micron ukunemba. Kusukela lokhu kuzokwandisa zincike inqubo attenuation.

Ngokuvamile, ebeka ye-fiber-optic kwenziwa ngesandla noma nokusetshenziswa ngamawinji ekhethekile. Ngo inqubo umsebenzi kufanele inake eziningi izici ezingathinta umphumela. Lapho ebeka apharathasi ekhethekile kumele asetshenziselwa ukusiza ukunciphisa Coefficient friction futhi ukugwema umonakalo ezindaweni eguqa. Kokuqina Kwenziwa ngamawinji, sokunquma traction. Ekupheleni imithombo ikhebula kwesokunxele wekhasi ukuze amabhokisi ikhebula.

Noma yimuphi ikhebula fibre optic kungaba kwimodi olulodwa noma multimode. Esimweni sokuqala, zonke imisebe unqobe indlela efanayo ukufinyelela umamukeli kanyekanye. Ukuze lolu hlobo ama-transceivers efanelekayo laser adlulisele ukukhanya nge wavelength oyifunayo. Kufanele kushiwo ukuthi izindleko impela high, kodwa esikhathini esizayo esiseduze, le ndlela ubhekwa le ethembisayo.

Ngokuqondene nozakwabo multimode, banayo kunokwehlukahluka okukhulu, ngenxa okuyinto kukhona ukuhlanekezela edilini lomshado. udumo lwawo kungenxa ngokuyinhloko cheapness isihlobo. Ukubambezeleka isignali kumanethiwekhi ezinjalo ngeke cishe zivumelana kagesi ikhebula amanethiwekhi.

Nakuba fibre optic ikhebuli has a Damping ababuthakathaka kakhulu, ine ukuhlakazwa esingokwemvelo chromatique, okuyinto endaweni yokudlulisela ehlukile ngokusebenzisa ingilazi. Ngakho, isiginali ukukhanya kungenziwa ukubola zibe ngabanye izingxenye umbala (rainbow umphumela). Ku-ingxenye encane uyakwazi ukungena kancane elilandelayo okwagcina kuholela ukulahleka kwedatha. Nokho, lokhu akusebenzi olulodwa-mode izintambo, lapho ukukhanya ngocansi has imvamisa efanayo. Lapho zisetshenziswa bona a chromatique ukuhlakazwa umphumela ingekho.

Eqinisweni, le ntambo fibre optic has a isakhiwo efana coaxial ingane yakini kagesi, kodwa kunalokho zethusi wire phakathi kuyinto mncane ingilazi fibre. Njengoba ukwahlukanisa yangaphakathi lapha ingilazi noma plastic emgodleni evimbela ophumayo yokukhanya. Singasho ukuthi wazinikezela ngokuphelele ibonisa ukukhanya esebenzisa izinto ezimbili okuyinto ehlukile Inkomba yezokubona. Kakhulu kuyaqabukela esetshenziswa sheathing sensimbi, njengoba akunandaba mqondo ukuvikela fibre optical kusukela ukuphazamiseka kagesi. Kodwa ngezinye izikhathi ukusebenzisa isivikelo esinjalo uma udinga ukuvikelwa mechanical kusuka imvelo.
