Tus neeg muag khoom puas tau dag cov neeg siv khoom? Tsis txhob ntshai, peb yuav piav qhia meej rau koj.
Ua ntej, cov khoom ntawmoptical fiber teeb liab repeater
Lub optical fiber repeater yog tsim los ntawm tsib qhov chaw: ze-kawg optical fiber tshuab, optical fiber jumper, tej thaj chaw deb optical fiber tshuab, feeder jumper thiab txais thiab xa xov tooj cua.
Qhov thib ob, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm optical fiber repeater Tom qab lub teeb liab wireless txuas los ntawm lub hauv paus chaw nres tsheb, nws nkag mus rau qhov ze-kawg optical fiber repeater. Qhov ze-kawg optical fiber repeater converts RF teeb liab mus rau hauv lub teeb liab kho qhov muag, thiab ces xa nws mus rau tej thaj chaw deb optical fiber repeater los ntawm lub optical fiber jumper, lub tej thaj chaw deb optical fiber repeater restores lub optical teeb liab mus rau lub teeb liab RF, thiab ces nkag mus rau hauv lub optical fiber jumper. RF chav nyob rau amplification, thiab lub teeb liab xa mus rau lub transmitting kav hlau txais xov tom qab amplification, npog lub hom phiaj cheeb tsam.
Thib peb, cov yam ntxwv tseem ceeb ntawmoptical fiber ntau repeater
1. Txais kev lim dej duplex nrog kev sib cais siab thiab qis qis qis kom tshem tawm cov dej ntws thiab nqes nqes crosstalk.
2. Lub kaw lus muaj suab nrov tsawg, zoo linearity, zoo tshaj plaws kev sib txuas lus zoo, thiab tsis cuam tshuam rau hauv paus chaw nres tsheb thiab lwm yam khoom siv wireless.
3. Muaj qhov kev soj ntsuam zoo meej, tuaj yeem saib xyuas thiab teeb tsa ntau qhov system tsis muaj, thaum txhawb kev saib xyuas tej thaj chaw deb wireless, muaj zog.
4. Optical fibers yog siv los txuas rau hauv zos thiab tej thaj chaw deb kawg, uas muab kev sib kis ntev thiab kev poob me me. Tsis tas li ntawd, lub luag haujlwm thiab ntau lub network tau txhawb kom yooj yim thiab yoog raws.
5. Lub module yog ntse thiab muaj kev sib koom ua ke, uas yog ib qho yooj yim los tswj, txhim kho thiab nruab.
Thaum kawg, qhov sib txawv ntawm fiber ntau repeater thiab wireless teeb liab repeater
Vim hais tias kev sib kis ntawm optical fiber repeater yog non-feeder, nws yeej tsis poob rau ultra-ntev deb deb teeb liab kis tau tus mob, thiab nws yog ntau haum rau ultra-ntev-ntev teeb liab kev pab them nqi tej yaam num. Lub wireless repeater siv feeder kis tau tus mob, yuav muaj kev poob rau hauv cov txheej txheem ntawm kev thauj mus los teeb liab, thiab qhov poob nce nrog qhov nce ntawm qhov deb, thiab qhov kev thauj mus los tsis tuaj yeem muab piv nrog optical fiber repeater.
Txawm li cas los xij, tus nqi ntawm optical fiber repeater kuj siab dua li ntawm wireless repeater, uas tuaj yeem xaiv raws li qhov chaw thiab pob nyiaj siv.
