Ob hom fiber ntau cables muaj cov yam ntxwv sib txawv rau ntau hom kev siv. OS2 SMF cables tsis tuaj yeem txuas nrog OS1 SMF cables, uas yuav ua rau lub teeb liab ua haujlwm tsis zoo.
Qhov txawv ntawm OS1 thiab OS2 yog dab tsi?
Qhov txawv ntawm OS1 thiab OS2 fiber ntau optic cables yog nyob rau hauv cable tsim es tsis yog optical fiber specifications. OS1 hom cable yog feem ntau ntawm kev siv nruj nreem thaum OS2 yog lub raj xoob lossis tshuab siv hluav taws xob uas cov qauv tsim siv siv tsawg dua kev ntxhov siab ntawm cov khoom siv kho qhov muag.
Yuav ua li cas fiber ntau yog OS2?
OS2: Optical Singlemode Fiber. Qhov feem ntau attenuation yog 0.40 dB / km ntawm 1310nm thiab 0.30 dB / km ntawm 1550nm. Ntawm Gigabit speeds, lub teeb liab yuav nquag mus txog 25km ntawm no fiber ntau (ntawm 1310nm) thiab mus txog 80km ntawm 1550nm.
OM1 thiab OM2 puas tuaj yeem ua haujlwm ua ke?
Nws tuaj yeem txuas cov hlua txuas rau fiber ntau optic cables uas muaj tib txoj kab uas hla, piv txwv li 62.5/125 (OM1) thaj cords tuaj yeem siv nrog 62.5/125 (OM1) cable thiab 50/125 (OM2/OM3/OM4) thaj qaum siv tau nrog 50/125 (OM2/OM3/OM4) cable.
Is OM1 obsolete?
OM1 thiab OM2, thawj 62.5 micron (µm) - thiab 50 µm-inch hom, raws li, raug suav tias tsis siv nyob rau hauv ISO / IEC 11801 thiab TIA 568 tus qauv, thiab tsis suav nrog hauv cov ntawv tseem ceeb ntawm cov ntaub ntawv. Lawv, txawm li cas los xij, tso cai raws li yawm txiv hom fiber ntau thiab tej zaumsiv los txuas ntxiv cov cuab yeej qub txeeg qub teg.

Puas yog cov lus hais thiab cov lus sib cav sib xws?
Raws li cov ntsiab lus hais, ib qho kev sib cav sib cav xav kom koj sib cav ntawm qhov pom tseeb. Nws cov ntsiab lus ntawm tus kheej thiab cov qauv hloov pauv ntawm kev muab hla thiab ntxiv dag zog rau qhov sawv ntsug kom ntseeg tau tus nyeem ntawv.
Puas yog kev sib tsoo tsis sib xws tiag tiag?
Nyob hauv ntiaj teb no kev sib tsoo feem ntau yog qhov chaw hauv nruab nrab elastic thiab zoo kawg nkaus inelastic. Ib lub pob poob los ntawm qhov siab h saum npoo av feem ntau thaws rov qab rau qee qhov siab tsawg dua h, nyob ntawm seb lub pob khov npaum li cas.
Puas yog subcultures thiab countercultures zoo sib xws thiab txawv?
Counterculture-Ib pawg uas nws cov txiaj ntsig thiab cov qauv sib txawv los ntawm lossis tsis sib haum nrog cov kab lis kev cai tseem ceeb: … Ib qho subculture yog just as nws suab-ib pawg kab lis kev cai me me hauv ib qho kab lis kev cai loj;
Puas yog kev sib tw tsis sib xws tib yam li kev sib xyaw ua ke?
Kev txwv tsis pub sib tw yog qee zaum xav tias yog tshwj xeeb ntawm kev sib xyaw inhibition. Hauv kev sib xyaw inhibition, tus inhibitor khi rau ib qho chaw allosteric, piv txwv li ib qhov chaw sib txawv ntawm qhov chaw nquag uas lub substrate khi.
Puas cov sib tov sib xyaw ua ke muaj cov khoom sib xws?
Ib homogeneous sib tov yog sib tov nyob rau hauv uas muaj pes tsawg leeg yog uniform thoob plaws qhov sib tov .. Qee cov ntaub ntawv hais ntxiv tias cov tshuaj lom neeg tsis tuaj yeem muab cais rau hauv nws cov ntsiab lus los ntawm kev sib cais ntawm lub cev, piv txwv li, tsis muaj kev cuam tshuam tshuaj lom neeg.
