Kev Taw Qhia Txog Khoom
Cov fiber optic yog ua los ntawm cov iav lossis cov yas xov uas xa cov ntaub ntawv ua lub teeb ci, muab cov ntaub ntawv xa mus sai heev. Nws tuaj yeem nqa cov ntaub ntawv ntau heev hla kev deb nrog qhov poob qis tshaj plaws. Tsis zoo li cov xov tooj liab ib txwm muaj, Optical Fiber tsis muaj kev cuam tshuam electromagnetic thiab kev cuam tshuam radiofrequency, lav qhov teeb liab huv si thiab txhim khu kev qha. Qhov zoo no ua rau Optical Fiber yog qhov kev xaiv zoo tshaj plaws rau kev sib txuas lus thiab kev sib txuas lus ntev.
Peb muab ntau yam khoom siv fiber ntau, suav nrog G.652.D, G.657.A1, G.657.A2, thiab ntau ntxiv kom tau raws li koj cov kev xav tau tshwj xeeb.
cov yam ntxwv
Cov fiber ntau uas peb muab muaj cov yam ntxwv hauv qab no:
1) Kev xaiv ntau yam txheej txheem kom tau raws li qhov xav tau ntawm ntau lub sijhawm thov.
2) Cov coefficient me me ntawm hom polarization dispersion, tsim nyog rau kev sib kis ceev ceev.
3) Kev tiv thaiv kev qaug zog zoo tshaj plaws, tsim nyog rau kev siv hauv ntau qhov chaw sib txawv.
Daim Ntawv Thov
Feem ntau siv rau ntau hom optical cable los ua lub luag haujlwm ntawm kev sib txuas lus.

Ntim Khoom
G.652D optical fiber raug coj mus rau ntawm cov yas spool, muab tso rau hauv lub thawv, thiab tom qab ntawd muab tso rau ntawm lub pallet thiab kho nrog zaj duab xis qhwv.
Cov yas spools muaj nyob rau hauv peb qhov ntau thiab tsawg.
1) 25.2km/lub spool
2) 48.6km/lub spool
3) 50.4km/spool
Kev Khaws Cia
1) Cov khoom yuav tsum khaws cia rau hauv qhov chaw huv si, huv si, qhuav thiab muaj cua nkag.
2) Cov khoom yuav tsum tsis txhob muab sib dhos ua ke nrog cov khoom uas yooj yim hlawv thiab yuav tsum tsis txhob nyob ze rau cov chaw hluav taws.
3) Cov khoom yuav tsum tsis txhob raug tshav ntuj ncaj qha thiab los nag.
4) Cov khoom yuav tsum tau ntim kom tag nrho kom tsis txhob muaj dej noo thiab ua rau muaj kuab paug.
5) Cov khoom yuav tsum tau tiv thaiv los ntawm kev nyuaj siab thiab lwm yam kev puas tsuaj thaum lub sijhawm khaws cia.
