Yintoni intambo yokukhanya yangaphandle?
Intambo yangaphandle yangaphandle luhlobo lwentambo yefiber optical esetyenziselwa ukuhanjiswa konxibelelwano. Ibonisa umaleko owongezelelweyo okhuselayo owaziwa ngokuba sisikrweqe okanye i-metal sheathing, enika ukhuseleko lomzimba kwimicu ye-optical, eyenza ibe yinto ehlala ixesha elide kwaye ikwazi ukusebenza kwiimeko ezinzima zokusingqongileyo.
Iiyantlukwano eziphambili phakathi kwe-G652D kunye ne-G657A2 ye-fiber ye-single-mode yile ilandelayo:
1 Ukugoba ukusebenza
Iifayibha ze-G657A2 zinika ukusebenza okuphezulu kokugoba xa kuthelekiswa neentsinga ze-G652D. Ziyilelwe ukuba zimelane ne-bend bend radii, zizenze zilungele ukusetyenziswa kwiinethiwekhi zokufikelela kwiimayile zokugqibela apho ukufakwa kwefayibha kunokubandakanya ukujika okubukhali kunye neekona.
2 Ukuhambelana
Iintsinga ze-G652D zibuyela ngasemva zihambelana neenkqubo ezindala, zizenza zibe lukhetho olukhethiweyo lokuphucula inethiwekhi kunye nofakelo apho ukuhambelana nezixhobo zelifa kubalulekile. Iifayibha ze-G657A2, ngakolunye uhlangothi, zinokufuna ukuqwalaselwa ngokucophelela kweziseko ezikhoyo ngaphambi kokuthunyelwa.
3 izicelo
Ngenxa yokusebenza kwabo okuphezulu kokugoba, iifayili ze-G657A2 zilungele ukusetyenziswa kwi-Fiber-to-the-Home (FTTH) kunye ne-Fiber-to-the-Building (FTTB) izicelo, apho iifayili zifuna ukuhamba ngeendawo eziqinileyo kunye neekona. Iintsinga ze-G652D ziqhele ukusetyenziswa kuthungelwano lwe-backbone olude kunye nothungelwano lwengingqi yemetropolitan.
Isishwankathelo, zombini i-G652D kunye ne-G657A2 i-fiber ye-single-mode ineenzuzo kunye nokusetyenziswa kwayo. I-G652D inikezela ngokuhambelana okugqwesileyo kunye neenkqubo zelifa kwaye ilungele uthungelwano olude. Kwelinye icala, i-G657A2 ibonelela ngokusebenza okungcono kokugoba, iyenza ibe lukhetho olukhethwayo lokufikelela kuthungelwano kunye nofakelo oluneemfuno eziqinileyo zokugoba. Ukukhetha uhlobo lwefayibha efanelekileyo kuxhomekeke kwiimfuno ezithile zenethiwekhi kunye nesicelo esijoliswe kuyo.
