Cov Ntaub Ntawv Tuav Rau Cov Khaub Ncaws Sab Hauv Chaw

Ua ib tug pib nyob rau hauv fiber ntau optic network, kuv tau siv los xav tias lub zog kho qhov muag yuav tsum muaj zog kom ntau li ntau tau. Txawm tias qee zaum peb siv cov khoom siv kho qhov muag los txhim kho qhov teeb meem kho qhov muag. Yog li cas cov tshuaj fiber ntau tau siv? Raws li peb paub, lub hauv paus ntawm cov hom fiber ntau yog laser, lub zog uas muaj zog heev. Yog li ntawd peb tuaj yeem siv tib lub hom fiber ntau kom ntev kis tau tus mob. Tab sis, yog hais tias qhov kis tau tus mob siab tshaj ib hom fiber ntau dhau lawm, ntau lub teeb kuj yuav tshaj ib tus fiber optic receiver, uas yuav ua rau muaj kev kub ntxhov siab yuam kev. Yuav daws tau qhov no li cas? Fiber theem yuav tsum muab tso rau ntawm lub receiver kawg kom txo tau lub hwj chim kom zoo. Muaj ob qho tib si sib txawv thiab ob qho tib si sib txawv rau cov neeg siv lub tshuab ua lag luam. Qhov kev paub ntawm tus kws kho lub cev muaj zog optic yuav tau nkag rau hauv tsab xov xwm no.

Dab Tsi Yog Tus Ntaus Dab Tsi?

Cov kws kho lub cev tsis muaj zog optic adenuator, tseem hu ua fixed plug type lossis fixed build-out fiber ntau, yog siv fiber ntau optic kom txo tau qhov optical fiber zog los ntawm tej theem. Cov kev raug rau kev txo nqi yog 1 thiab 30 dB. Feem ntau, nws muaj ib tug txiv neej ntsaws rau ntawm ib sab tso cai rau tus neeg siv lub fais fab kom txuas mus rau hauv cov khoom siv los sis lub nplais ntawm lub khawm thaj, thiab muaj poj niam hom fiber optic adapter rau sab nraud kom cia cov hlua khi rau ntsaws rau hauv. lub npe ntawm tus kws kho mob lub npe yog nyob ntawm tus qauv sib txuas thiab qhov kev poob qib. LC attenuator 5dB txhais tau hais tias tus neeg siv lub npe no siv LC fiber optic connector, thiab nws txo tau qhov optical fiber ntau zog los ntawm 5dB.

Taag Fiber Txhawb Nqa

Ntsuas Fiber Optic Lub Ntaus Hom

Fixed fiber optic attenuators muaj nyob hauv LC, SC, ST, FC thiab MU style nrog APC thiab UPC txhuam. Feem ntau, cov tshuab multimode tsis tas yuav tsum tau ua rau cov neeg siv ntau qhov chaw, VCSELs, tsis tshua muaj kev tawm hwj huam txaus kom txaus rau cov khoom txais. Xwb, ib lub kaw lus nruab nrab, tshwj xeeb tshaj plaws kev sib txuas, feem ntau muaj ntau lub zog thiab xav tau attenuators. Vim li no, cov kws kho lub cev muaj fiber ntau ntau yog hom ib hom. Hom kev siv ntau tshaj plaws yog LC ib hom poj niam rau txiv neej thiab poj niam rau cov poj niam uas kho tau tus kws kho mob ntau dua. Tsis zoo li cov poj niam ua rau txiv neej hais los saum toj no, tus poj niam rau cov poj niam uas kho kom tsis muaj fiber ntau optic attenuators muaj poj niam hom fiber optic adapter ntawm ob hnub, uas kuj yog li ntawd hu ua fiber ntau optic adapter hom attenuators. Lawv tuaj yeem siv ua adapters thiab attenuators tib lub sijhawm.

Cov Khoom Uas Siv Fiber Ntau Hom Tshuaj

Yuav Siv Li Cas Fiber Taub Hauv Chaw?

Raws li hauv daim duab hauv qab no, cov kws kho qhov muag ceev faj yuav tsum nco ntsoov nruab rau ntawm lub receiver kawg ntawm qhov txuas (X hauv daim duab). Qhov no yog vim nws yooj yim dua los ntsuam xyuas lub hwj chim ntawm lub receiver ua ntej thiab tom qab kev poob qib los yog thaum kho nws nrog koj lub hwj chim ntsuas ntawm lub receiver, ntxiv rau txhua qhov kev xav yuav raug muab rov rau nws txoj kev rov qab mus rau qhov chaw.

Yuav Siv Li Cas Fiber Ntau Hauv Qhov Chaw

Rau cov poj niam rau cov txiv neej uas muaj fiber ntau optic attenuators, peb tuaj yeem ntsaws lub nruas qaum rau cov poj niam fiber optic adapter ntawm tus kws qhia ntawv. Thiab ces ntsaws cov txiv neej ntsaws ntawm tus attenuator rau cov khoom ncaj qha. Rau cov poj niam ua rau cov poj niam kws kho mob hnyav, peb yuav tsum ntsaws ob kab ntsaws rau ob tus poj niam lub ntsej muag optic adapter ntawm tus kws qhia ntawv (hauv daim duab hauv qab).

Poj Niam rau Txiv neej Fiber Optic Attenuators

FOCC Fixed Fiber Intenuator Tshuaj

FOCC muab ntau hom kev kho fais fab foob hom ib hom fiber ntau kws kho qis nrog cov yeem rau tus nqi ntawm 1dB mus rau 30dB. Lawv raug siv ncaj qha rau cov fibre optic connectors thiab muab cov theem kho qhov muag tsis tiav. Peb cov khoom siv fiber ntau hauv qab muaj qhov poob qis thiab ua haujlwm ntawm 1310nm thiab 1550nm wavelength ntau. LC thiab SC fibre connector hom nrog UPC los yog APC polish muaj, nrog rau cov hom phiaj ST thiab FC hom ntawm attenuators.
