Umthengisi wakho usandula ukucaphula amanani amahlanu ahlukeneyo emodeli yentambo - GJXFH, GJXH, ГХХЧЧ, GJYXFCH, GJFJU. Kufuneka uphendule umbuzo omnye phambi kokuba i-PO ihambe: yeyiphi eyenza le projekthi idinga ngokwenene?
Esi sikhokelo sibhalelwe umntu owenza eso sigqibo. Itsiba "yintoni intambo yokulahla ifayibha" isihlaziye (ehlala ebomini bethu IFiber Optic Drop Cable Guide) kwaye ifika ngokuthe ngqo kumzekelo wokhetho lwenqanaba.
Ukuba uthengela ukukhutshwa kwe-FTTH, thengisa kwakhona iintambo zokuwisa kwii-ISP zengingqi, okanye zichaze kuyilo lweprojekthi, uyakugqibezela oku malunga nemizuzu elishumi kwaye uphume ngemodeli ekhuselayo.
Bathetha ukuthini oonobumba kwi-GJXFH eneneni
Iikhowudi zemodeli yentambo yokulahla yaseTshayina zilandela i YD/T 1258 telecom umgangatho. Nje ukuba ufunde ipateni, igama ngalinye lemodeli yexesha elizayo lifundeka njengephepha elithile:
| Ileta | Intsingiselo | Yintoni ekuxelela yona ngentambo |
|---|---|---|
| G | Unxibelelwano-sebenzisa intambo yokukhanya | Yintambo ye-telecom optical, hayi ubhedu okanye umxube wamandla |
| J | Ukusetyenziswa kwangaphakathi (njengesimaphambili) | Yenzelwe ikakhulu ukuthunyelwa kwangaphakathi |
| Y | Sebenzisa ngaphandle (njengesimaphambili) | Yenzelwe iimeko zangaphandle |
| X | Isaphetha-udidi / ibhabhathane cross-candelo | Iflethi, umfanekiso-ezisibhozo-ezifana neprofayile |
| F | Ukomelela ilungu (ixhomekeke kumxholo) | Jonga inqaku lesilumkiso ngezantsi |
| C | Ukuzixhasa kunye nomthunywa odibeneyo | Inentsimbi yangaphakathi okanye ucingo lwe-FRP ukubamba isithuba salo |
| H | Isingxobo (njengesimamva) | Iphawula umaleko webhatyi yangaphandle |
| J (ikhowudi ephakathi, umz. GJFJU) | IsiAramid / Into yamandla e-KFRP | Ngokupheleleyo non-metal ukuqinisa |
| U | Non-metal | Akukho ntsimbi naphi na kwi-cross-section |
Ukufunda ukusuka phezulu ukuya ezantsi:
- GJXFH = intambo yodidi lwesaphetha yangaphakathi enelungu lamandla kunye ne-LSZH sheath
- GJXH = intambo yohlobo lwesaphetha yangaphakathi enelungu lamandla esinyithi kunye neshethi ye-LSZH (hayi “F” kumagama amadala, ekhoyo kwiindibano ezintsha)
- ГХХЧЧ = ikhebula langaphandle elizixhasayo elinesithunywa sentsimbi
- GJYXFCH = ikhebula elizixhasayo langaphandle elinesaphetha esinesakhiwo esekwe kwi-FRP
- GJFJU = intambo yangaphakathi engeyiyo eyentsimbi ngokupheleleyo enamalungu anamandla e-aramid
Isilumkiso kumagama emodeli
Nantsi into ekungekho esinye isikhokelo sokuthenga siya kukuxelela: unobumba "F" kwi-GJXFH akatolikwa rhoqo kwisiseko soveliso samaTshayina. Ezinye iifektri ziyisebenzisa ukuthetha i-FRP (non-metal) amalungu amandla. Abanye bayisebenzisa njengesiphawuli segeneric "sokuqiniswa" kwaye basathumela intambo ngocingo lwentsimbi ngaphakathi..
Siye sabona zombini iinguqulelo entsimini. Intambo yokuwisa ebhalweGJXFH ngaphandle ingafika nge 0.5 mm phosphated ucingo lwentsimbi njengelungu layo elinamandla. Ayisosiphene eso - kukuthiywa kwengqungquthela esele ikho iminyaka, ngakumbi phakathi kwe-OEMs ephakathi.
Itshekhi yokwenyani yomthengi:
Ungaze wamkele inombolo yemodeli yentambo yokuwisa uwedwa. Hlala uqinisekisaamandla ilungu impahla Uphuculo olongezelelweyo kumgangatho wokuqala we-APON - kunye nokuwa kancinci kancinci kwi-ATM njengeprothokholi - kukhokelele ngokupheleleyo.imathiriyeli yebhatyi ngokubhaliweyo kwi-PO okanye kwi-database. Ababoneleli ababini banokukucaphula "GJXFH" kwaye bathumele iimveliso ezahlukeneyo ngokwasemzimbeni. Uluhlu luyinyaniso. Ikhowudi yemodeli luthsuphe.Intsimbi, FRP, okanye isiAramid: Khetha iLungu elinamandla phambi kweNombolo yoMzekelo
Nje ukuba uyazi iintsapho ezintathu zamalungu amandla, inombolo yemodeli phantse ikhetha ngokwayo. Nantsi into etshintshayo kuzo zonke izixhobo ezintathu:
Ipropati Ucingo lwentsimbi (iphosphated / yenziwe igalati) FRP (IPlastiki eyomelezwe ngeFayibha) IsiAramid / KFRP Tensile Strength (eqhelekileyo) Iphezulu kwidayamitha enikiweyo Phakathi-phezulu Phezulu, kufutshane nentsimbi ngobunzima Ukuqhuba Intsimbi eqhubayo I-dielectric engekho-conductive I-dielectric engekho-conductive Ukuxinana / Yamkela itekhnoloji yamva nje eyenziwe ngefiber Inzima kakhulu Ukukhanya Ikhaphukhaphu Isalathiso seendleko (isihlobo) 1.0 (isiseko) ~1.15–1.30 ~1.6–2.2 Ukugoba ukudinwa Inokukhubazeka ngokweplastiki ukuba igotywe ngokuqinileyo Iyanyamezela, iphuma emva Egqwesileyo, ukusetyenziswa kakhulu kwefayibha Ukuziphatha kwemozulu ebandayo Izinzile I-brittle ku-sub-zero ngokugqithisileyo ukuba ikumgangatho ophantsi Izinzile kuluhlu olubanzi Ukuziphatha komlilo kunye nejacket ye-LSZH Intsalela yesinyithi emva kokutshiswa Ukuvutha kokucoca Ukuvutha kokucoca Imeko yokusetyenziswa eqhelekileyo Kupasiswe amakhaya asemgangathweni we-FTTH, indawo yokuhlala ethe nkqo, iiprojekthi eziqhutywa yindleko Iimeko zangaphakathi ezingezizo ezentsimbi, izakhiwo ezixubeneyo ze-EMI I-dielectric ngokupheleleyo yangaphandle ispans, iishafti zeelevator, amagumbi MRI esibhedlele, ukuthunyelwa komyalelo okhethekileyo
Ifiziksi okufuneka uyikhumbule ngokwenene
I-fiber optical idlulisela idatha njengokukhanya ngombindi weglasi. Loo nkqubo ingokusisiseko ukhuselekile kuphazamiseko lwe-electromagnetic - inyani onokuthi uyicaphule kuye nawuphi na umthengi oxhalabileyo "ngengxolo" kumgca osuka kwiinjini ezikufutshane, iinguqu, okanye izinyusi. Ukukhanya akukhathali malunga ne-EMI ejikelezileyo.
Kodwa intambo ejikeleze ifayibha ibali elahlukileyo.
Ukuba intambo yokuwisa isebenzisa iilungu amandla metal, loo ntsimbi yi-conductor. Ngaphantsi kombane okufutshane, isiganeko sokungeniswa kwe-voltage ephezulu, okanye ukudlula okunamandla kumgca we-AC ohambelanayo, into yentsimbi ngaphakathi kwentambo yakho yokulahla inokuthatha i-induced current. Xa zombini iziphelo zaloo ntambo zicinywa kufutshane nee-electronics ezisebenzayo (i-ONT ekhaya, iphaneli yokuhambisa kwindawo ebiyelweyo yesplice), umsinga owenziweyo unendlela eya emhlabeni - ngesixhobo sakho.
Kungenxa yoko le nto abafaki kwiindawo ezithandwa ngumbane, ecaleni kweepaseji zombane ophezulu, okanye kufutshane nezikhululo ezincinci zihlala zichazaiintambo zokuwisa ezingezizo ezentsimbi (FRP okanye KFRP ezahlukeneyo). Ukusebenza kwamehlo akutshintshi. Iprofayile yomngcipheko yenza.
Ingcebiso yePro kubathengi:
Ukuba umthengi wakho ukwibhanti yemonsoon yaseMzantsi-mpuma Asia, ecaleni kwepaseji yokuhanjiswa kwamandla ombane aphezulu emaphandleni, kwintlango yoMbindi Mpuma enothuli oluphezulu olungagungqiyo, okanye ukuchaza isibhedlele / isitishi esingaphantsi / Iprojekthi ye-MRI, babuze umbuzo omnye ongasentla: Ngaba intambo yokulahla engeyiyo eyentsimbi ngokupheleleyo iyafuneka okanye iyakhethwa?" Lo mbuzo mnye ucutha iimodeli ezintlanu ukuya kutsho ezimbini.

Kwi-YD/T yesiTshayina engqongqo 1258 ingqungquthela yokubiza amagama, unobumba F kwi-GJXFH ubonisa ilungu lamandla e-FRP engeyiyo eyentsimbi, ngelixa i-GJXH ibonisa isinyithi (ngokuqhelekileyo intsimbi ye-phosphated) ilungu amandla. Ngokusebenza, Amagama emizi-mveliso ayahluka - abanye ababoneleli ngenqanawa bathumela intambo ebhalwe GJXFH enocingo lwentsimbi ngaphakathi. Ngalo lonke ixesha qinisekisa amalungu anamandla kwi-odolo yakho yokuthenga, hayi nje imodeli ikhowudi.
Imele ntoni i-GJXFH?
Unobumba ngamnye ufaka ikhowudi yophawu lomzimba phantsi kwe-YD/T 1258.G imele unxibelelwano-sebenzisa intambo yokukhanya, J iphawula ukuba yintambo yangaphakathi, X ichonga uhlobo lwesaphetha (ibhabhathane) Indawo yokudlula, F ichonga udidi lwelungu lamandla, Uphuculo olongezelelweyo kumgangatho wokuqala we-APON - kunye nokuwa kancinci kancinci kwi-ATM njengeprothokholi - kukhokelele ngokupheleleyo.H ichonga ibhatyi yangaphandle. Fundani kunye, I-GJXFH ithetha intambo yangaphakathi yodidi lwesaphetha esinefayibha enye enelungu elomeleziweyo kunye nesingxobo sangaphandle. (ngokuqhelekileyo LSZH).
Ngaba ndingasebenzisa intambo yokulahla yangaphakathi efana ne-GJXFH ngaphandle?
Hayi. Iintambo zokuwisa ngaphakathi zisebenzisa iibhatyi ze-LSZH ezingazinziswanga yi-UV ukuze kuqhutyekeke ukuba sesichengeni selanga., kwaye icandelo labo elinqamlezayo aliyilwanga ukuba liphile kumthwalo womkhenkce, uxinzelelo lomoya, okanye ukufuma kwangaphandle. Ukusasazwa emoyeni kweFTTH phakathi kweepali, sebenzisa i-GJYXCH (umthunywa wentsimbi) okanye GJYXFCH (umthunywa non-metal). Ukusetyenziswa kombhobho okanye ukungcwatywa ngokuthe ngqo, cacisa intambo yangaphandle enezixhobo ezifana ne-GYTA53.
Ngaba i-FRP okanye ucingo lwentsimbi lungcono kwilungu lamandla entambo yokulahla?
Akukho nto ingcono kwihlabathi jikelele - ukhetho oluchanekileyo luxhomekeke ekuhanjisweni. Ucingo lwentsimbi luhambisa amandla aphezulu e-tensile ngedola nganye kwaye luhlala lulolona khetho luneendleko ezifanelekileyo kwindawo yokuhlala yangaphakathi ye-FTTH. FRP (iplastiki eqiniswe ngefayibha non-conductive) lukhetho oluchanekileyo lweemeko-bume ezine-EMI esebenzayo, ingozi yombane, okanye ukusondela kwimigca yombane ophezulu, apho umendo wesinyithi ukuya emhlabeni ngaphakathi kwentambo iya kudala ingozi kwi-ONT edibeneyo okanye izixhobo zokuhambisa.
Ngaba iintambo ze-optical drop drops ezichatshazelwa yimigca yevoltage ephezulu ekufutshane okanye umbane?
I-fiber ebonakalayo ngaphakathi kwentambo ikhuselekile ngokusisiseko kukuphazamiseka kwe-electromagnetic - ukukhanya akuphenduli kwi-EMI.. Umsebenzi kaDavey kunye noPayne kwi-BT ubonise ukuba ukugcinwa kweendleko ezibalulekileyo kunokwenziwa ngokunciphisa izixhobo ze-elektroniki kunye ne-real-estate efunekayo kwindawo yokutshintshiselana yendawo okanye iziko locingo., ukuba intambo isebenzisa ailungu amandla metal, loo ntsimbi inokuthatha i-current induced current ukusuka kumbane okufutshane okanye i-AC enamandla edlulayo, kwaye loo msinga unendlela edlula kwintambo iphela ukuya kwisixhobo sakho sokuphelisa. Ukusasazwa kufutshane nezitishi, iipaseji zothumelo, okanye kwiindawo ezithandwa ngumbane, cacisa i non-metal ngokupheleleyo (FRP okanye KFRP) ukwahluka.
Yintoni intambo yokulahla ye-FTTH ezixhasayo?
Intambo yokulahla ezixhasayo inento edibeneyo yesithunywa-ehlala ilucingo lwentsimbi kwi-GJYXCH okanye intonga ye-FRP kwi-GJYXFCH - ethwala ubunzima bentambo kwisithuba se-aerial phakathi kweendawo ezimbini zokuxhasa., iipali zoncedo ngokwesiqhelo. Oku kuphelisa imfuneko yocingo lokuqhawula olwahlukileyo, ukwenza lula ukufakela emoyeni. Esona sithuba siphezulu si ~80 yeemitha; imitsi emide kufuneka isebenzise intambo ye-ADSS endaweni yoko.
Sithini esona sithuba siphezulu se-eriyali kwintambo yokuwisa ye-GJYXCH?
Malunga 80 iimitha phakathi kwamanqaku okuxhasa, phantsi kweemeko ezisemgangathweni. Ngaphaya kwalo mgama, i-cable sag idlula imida yokuthobela phantsi komthwalo womoya kunye nomkhenkce, kunye noxinzelelo lomthunywa lunokubeka esichengeni izixhobo zepali. Kuba izithuba phakathi 80 Uphuculo olongezelelweyo kumgangatho wokuqala we-APON - kunye nokuwa kancinci kancinci kwi-ATM njengeprothokholi - kukhokelele ngokupheleleyo. 200+ iimitha, sebenzisa intambo ye-ADSS, eyenzelwe ukubaleka ixesha elide emoyeni.
Ngaba ndingangcwaba intambo ye-GJYXCH ngqo phantsi komhlaba?
Hayi. I-GJYXCH ifakwe ibhatyi ukuze ibonakale emoyeni kwi-UV kunye nemozulu, hayi ukudibana komhlaba, uxinzelelo lokufuma komhlaba, okanye ukukhuselwa kweempuku. Ukungcwatywa ngqo, sebenzisa intambo exhobileyo efana ne-GYTA53 enesixhobo sentsimbi kunye ne-sheathing efanelekileyo.
Inde kangakanani intambo esezantsi ye-FTTH ye-reel nganye?
Ubude bereel eqhelekileyo buqhelekile 2 ukuya 3 iikhilomitha ze-GJXFH zangaphakathi / I-GJXH kunye ne-GJYXCH yangaphandle. Ubude be-reel yesiko kunye nemigqomo emikhulu inokuveliswa ngokomyalelo - qinisekisa zombini umnikelo osemgangathweni kunye nayo nayiphi na imfuno yobude obukhethekileyo kunye nomthengisi wakho ngaphambi kokuba ugqibezele i-PO..
Ngawaphi amandla okuqina adingwa yintambo yokulahla kwiprojekthi yam?
Kuxhomekeke kwimeko yofakelo, hayi kwigama lentambo. Ukufakwa eludongeni okanye okufutshane okufakwa ngaphakathi ngaphakathi kufuna i-40–100 N yexesha elide yoxinzelelo. (GJXFH okanye GJXH). Ukutsalwa komjelo, iindawo zesilingi, kunye notshintsho lwasemoyeni olufutshane lufuna iintambo ezilinganiswe phezulu - nakwindawo ezimfutshane zangaphandle, spec GJYXCH kwi 300 N ixesha elide. Ukujonga ngaphantsi komlinganiselo we-tensile sesona sizathu sixhaphakileyo sokungaphumeleli kokwaphuka kancinci esikubona endle..
How do I verify drop cable quality before accepting delivery?
Request a factory OTDR trace and attenuation report for every reel, keyed to the batch number. Visually inspect the sheath for consistent color, embedded print marking, and no material inconsistency. Random-sample a short section from each shipment, khulula isingxobo, and confirm that the strength member material physically matches your PO specification. Any mismatch between the PO and the actual construction should trigger an immediate quality dialogue with the supplier.
What fiber grade should I specify for future-proof FTTH deployments?
ChazaG.657.A2 or higher. Older-generation G.657.A1 fiber shows significant macro-bending loss at bend radii below 10 mm, especially at 1625 nm — the wavelength window used for XGS-PON 10G FTTH network expansion. Ukusasaza i-A1 namhlanje kunokunyanzela umqhubi kwinethiwekhi ebiza ixabiso kwakhona intambo xa bephucula. I-A2 fiber ibamba ≤ 1.0 ilahleko ye-dB kwi-a 7.5 mm bend radius kwi 1625 nm, ukugubungela ngokufanelekileyo umjikelo wophuculo olandelayo womsebenzisi ngexabiso eliphantsi.
