Dab tsi yog qhov sib txawv ntawm tib hom thiab Multimode Fiber ntau?
Nyob rau hauv qhov chaw zov me nyuam, tib hom thiab ntau lub fiber ntau cable optic cable feem ntau siv. Li cas los xij, Dab tsi yog qhov txawv ntawm ib hom thiab multimode fiber? Niaj hnub no, tsab xov xwm no yuav muaj qhov qhia txog peb.
Luv qhia Taw qhia txog tib hom thiab Multimode Fiber
Ib hom fiber ntau tsuas yog txuas nrog ib qho kev sib txuas lus xwb, feem ntau yog siv cov kev sib kis ntev. Nrhiav cov tshuab fiber ntau hauv multimode yog nrog ntau yam fiber ntau kis, hos nyob rau hauv txoj kev kis luv luv. Tsuas yog qhov no, qhov txawv nruab nrab ntawm ib hom thiab multimode fiber kuj pom nyob rau hauv cov no.
Tib hom VS Multimode Fiber ntau
Bandwidth: Vim lawv qhov txawv ntawm cov hom channel, lawv txawv hauv bandwidth. Lub bandwidth ntawm ib hom thiab multimode fiber feem ntau yog 2000MHz / Km thiab 50 MHz ~ 500MHz / Km.
Wavelength: Lub fib fib faj muaj fiber ntau muaj 850nm, 1310nm thiab 1550nm. 850mn feem ntau yog rau kev sib txuas ntawm multimode fiber ntau; 1550nm feem ntau yog rau ib hom fiber ntau txuas; Thaum 1310mn yog rau tib qho tib hom thiab multimode fiber interconnection. Rau qee degree, tus attenuation ntawm 850mn loj dua, tab sis pheej yig rau 2 ~ 3MILE (1MILE = 1604m) interconnection.
Kev Kis Xeeb Kev sib txuam: Multimode fiber ntau feem ntau siv nyob rau hauv Network nrog tus nqi qis dua thiab kis tau nrug luv dua, xws li LAN. Xws li ntawm Network yog feem ntau nrog cov yeeb yam no, xws li nrog ntau lub pob, cov plob tsis so ntswg, kev sib tham, kev siv cov khoom sib txuas thiab kev sib koom tes, thiab nrog ntau lub teeb pom kev zoo nyob hauv txhua qhov ntev. Kev siv cov tshuab fiber ntau multimedia pab kom txuag tau tus nqi Network. Thaum ib leeg-hom optical fibre feem ntau yog siv hauv lub network nrog ntev nrug thiab kuj qis kis tus nqi, xws li lub cev ntev kis thiab kis las Man.
Txoj kab uas hla: Txoj kab uas hla ntawm cov hom fiber ntau yog luv luv, li 10 hli. Nws tsuas yog muaj rau ib hom kis tau tus mob, nrog me dispersion, ua hauj lwm ntawm 1310nm thiab 1550nm wavelength, thiab nquag ob peb nrog cov khoom muag kho qhov muag. Thaum lub taub ntawm lub tshuab fiber ntau multimode yog ntev, li ntawm 62.5mm lossis 50m m. Nws muaj nyob rau 175,000 hom 'kis tau tus mob, nrog loj dispersion, ua hauj lwm ntawm 850nm los yog 1310nm wavelength, kuj yooj yim mus cuag nrog cov khoom muag kho qhov muag.

Txawm li cas los xij, rau qhov kho qhov muag pom tau zoo, tiag tiag hais, tsis muaj qhov txawv ntawm hom, seb hais txog tib hom lossis multimode. Thiaj li hu ua single-mode thiab multimode optic transceiver module txhais tau hais tias cov khoom kho qhov muag tau txais los ntawm qhov kawg ntawm optics match nrog qee hom fiber ntau mus txog qhov zoo tshaj plaws kis tau tus mob.
Tshaj tag nrho yog hais txog qhov txawv ntawm ib hom thiab multimode fiber. Yog tias xav paub ntau ntxiv, thov tos txais peb!
