Uthini umahluko phakathi kwentambo ye-250μm ye-loose-tube kunye ne-900μm ye-tight-tube cable?
I-250µm intambo yetyhubhu ekhululekileyo kunye ne-900µm ye-tight-tube cable zintlobo ezimbini ezahlukeneyo zeentambo ezinombindi wedayamitha efanayo, i-cladding, kunye ne-coating.Nangona kunjalo, kusekho iiyantlukwano phakathi kwezi zibini, eziqulethwe kwisakhiwo, umsebenzi, iingenelo, izinto ezingeloncedo, njl., Ezenza ukuba zombini zihluke kwisicelo.
Kwimeko ye-fiber-tube fiber, ifakwe nge-helically kwi-tube ye-semi-rigid, evumela ukuba intambo yandiswe ngaphandle kokwelula i-fiber ngokwayo.I-250μm i-fiber ye-tube ekhululekile iqulunqwe ngundoqo, i-125μm i-cladding kunye ne-250μm yokugqoka.Ngokuqhelekileyo, inani lee-cores kwi-250μm i-loose-tube optical cable iphakathi kwe-6 kunye ne-144. Ngaphandle kwe-6-core loose-tube optical cable, ezinye iintambo ze-optical zivame ukuqulunqwa ngama-cores angama-12 njengeyunithi esisiseko.
Ukwahluke kwisakhiwo esikhankanywe ngasentla, i-900 μm i-fiber optical egxininisiweyo inebhatyi yeplastiki enzima ngaphezu kwe-250 μm i-loose-tube optical fiber structure, engadlala indima yokukhusela.I-900μm i-tight-buffered fiber iquka i-core, i-125μm yokugquma, i-250μm yokugqoka (eyiplastiki ethambileyo), kunye nejacket (eyiplastiki eqinile).Phakathi kwazo, umaleko wokugquma kunye nomgangatho wejacket uya kunceda ukwahlula ukufuma ekungeneni kumbindi wefiber, kwaye unokuthintela ingxaki engundoqo yokuvezwa okubangelwa kukugoba okanye ukucinezelwa xa intambo ye-optical ibekwe phantsi kwamanzi.Inani lee-cores kwi-900μm i-tight-buffered cable idla ngokuba phakathi kwe-2 kunye ne-144, kunye ne-tight-buffer cable enenani elikhulu lee-cores ngokusisiseko iqulunqwe yi-6 okanye i-12 ye-cores njengeyunithi esisiseko.
Ngenxa yeempawu ezahlukeneyo zokusebenza ze-250μm intambo yetyhubhu evulekileyo kunye ne-900μm intambo yetyhubhu eqinile, ukusetyenziswa kwezi zibini kwahlukile.I-250μm intambo yetyhubhu evulekileyo ifanelekile kwiindawo ezinzima kwaye isetyenziswa ngokubanzi ngaphandle.Xa kuthelekiswa ne-900μm ye-tight-buffer optical cable, i-250μm loose-buffer optical cable inamandla aphezulu okuqina, ukuxhathisa ukufuma kunye nokumelana nobushushu obuphezulu, kwaye ifanelekile kwiindawo ezinokutshintsha kobushushu kunye nokufuma okuphezulu.Nangona kunjalo, ukuba yoluliwe kakhulu, iya kukhupha i-core kwijeli.Kwakhona, i-250µm intambo yetyhubhu ekhululekileyo isenokungabi lukhetho lulungileyo xa kufuneka umzila ojikeleze ukugoba okuninzi.
