Tsis muaj ib qho "standard" ntev. Qhov ntev ntawm cov khoom muaj xws li 1 m, 2 m, 3 m, 5 m, 10 m, 15 m, thiab 30 m. Qhov ntev yog nyob ntawm koj qhov kev ncua deb ntxiv nrog rau qhov kev pabcuam tsim nyog. Feem ntau manufacturers kuj muab kev cai ntev.
Kuv yuav tsum xaiv cov khoom tsho dab tsi?
PVC rau kev siv sab hauv tsev, LSZH rau cov chaw kaw lossis cov chaw pej xeem (tshwj xeeb yog qhov chaw IEC 60332 lossis cov qauv zoo sib xws), OFNR rau riser shafts ntawm cov plag tsev, OFNP rau plenum huab cua - tuav qhov chaw, thiab sab nraum zoov - cov tsho tiv thaiv rau sab nrauv lossis sab nrauv.
Dab tsi ua rau muaj qhov poob siab hauv cov hlua fiber ntau?
Feem ntau ua rau muaj cov kab mob ferrule kawg ntawm lub ntsej muag (plua plav, roj, ntiv tes), puas los yog khawb ferrules, tsis zoo fiber core alignment, ntau bending, thiab siv hom fiber ntau tsis ncaj ncees lawm los yog polish hom rau daim ntawv thov. Qhov kawg tsis tu ncua- ntxuav lub ntsej muag thiab tshuaj xyuas yog cov kev tiv thaiv zoo tshaj plaws.
Cov fiber ntau thaj cords puas tuaj yeem kho tau?
Yog lawm. Feem ntau cov tuam ntxhab muab cov kev cai configurations: kev sib txuas tshwj xeeb (xws li LC rau SC, LC rau FC), kev cai ntev, kev xaiv cov qib fiber ntau, txoj kab uas hla, cov khoom siv lub tsho, thiab xim. Rau kev txiav txim kev cai, muab cov lus qhia ua tiav - saib daim ntawv teev kev txiav txim saum toj no.

Lub fiber optic thaj qaum yog ib qho ncaj ncaj, tab sis xaiv qhov tsis ncaj ncees lawm yuav ua rau muaj teeb meem tiag tiag - los ntawm kev sib txuas tsis ua hauj lwm thiab teeb liab degradation rau connector puas tsuaj uas yuav tsum tau rework. Qhov tseem ceeb yog kom phim txhua qhov kev ntsuas rau qhov tseeb daim ntawv thov: connector hom rau cov khoom siv chaw nres nkoj, fiber ntau hom rau lub transceiver, polish hom mus rau lub network architecture, tsho ntsuam xyuas rau lub installation ib puag ncig, thiab cable ntev mus rau lub cev routing txoj kev.
Rau ntau lub network,LC, SC, FC, ST, thiab MPO / MTP thaj qaumnpog cov txheej txheem kev cai. Rau qhov xav tau ntau dua ib puag ncig - cov nroj tsuag muaj, sab nraum zoov yees, siab - ntom ntom racks - armored, waterproof, thiab uniboot xaiv ua qhov sib txawv. Ua ntej tso ib qho kev txiav txim, ua hauj lwm los ntawm daim ntawv teev npe tshwj xeeb, txheeb xyuas ob qhov kawg ntawm kev sib txuas, thiab paub meej tias qhov chaw teeb tsa. Cov txheej txheem ntawd yuav siv sijhawm feeb thiab tiv thaiv hom kev daws teeb meem uas raug nqi teev.
Yog hais tias koj xav tau kev pab qhia ib thaj qaum rau ib qhov project,tiv tauj peb pab pawg engineeringnrog koj cov ntaub ntawv thov, thiab peb tuaj yeem pom zoo rau kev teeb tsa raug.
