Uyini umehluko phakathi kwekhebula le-loose-tube engu-250μm nentambo yeshubhu eqinile engu-900μm?
Ikhebuli engu-250µm loose-tube kanye nekhebuli ye-tight-tube engu-900µm yizinhlobo ezimbili ezihlukene zamakhebuli anomgogodla ofanayo wobubanzi, i-cladding, ne-coating. Kodwa-ke, kusenomehluko phakathi kwalokhu okubili, okuhlanganiswe nesakhiwo, umsebenzi, izinzuzo, ukungalungi, njll, okwenza kokubili kuhluke ekusetshenzisweni.
Endabeni ye-loose-tube fiber, ifakwa nge-helically ku-semi-rigid tube, okuvumela ikhebula ukuthi inwetshwe ngaphandle kokunweba i-fiber ngokwayo. I-250μm loose tube fiber yakhiwe core, 125μm cladding kanye 250μm enamathela. Ngokuvamile, inani lama-cores kukhebula le-loose-tube optical engu-250μm liphakathi kuka-6 no-144. Ngaphandle kwekhebula le-6-core loose-tube optical cable, ezinye izintambo ezibonakalayo zivame ukwakhiwa ngamakhora angu-12 njengeyunithi eyisisekelo.
Ngokungafani nesakhiwo esishiwo ngenhla se-loose-tube, i-900 μm i-tight-buffered optical fiber inejazi lepulasitiki eliqinile ngaphezu kwe-250 μm i-loose-tube optical fiber structure, engadlala indima yokuvikela. I-900μm i-tight-buffered fiber iqukethe i-core, i-cladding engu-125μm, i-coating engu-250μm (okuyipulasitiki ethambile), nejakhethi (okuyipulasitiki eqinile). Phakathi kwazo, isendlalelo sokumboza kanye nesendlalelo sejazi kuzosiza ukuhlukanisa umswakama ekungeneni kwe-fiber core, futhi kungavimbela inkinga yokuvezwa okuyinhloko okubangelwa ukugoba noma ukucindezelwa lapho ikhebula le-optical libekwe ngaphansi kwamanzi. Inani lama-cores kukhebuli e-tight-buffered engu-900μm ngokuvamile liphakathi kuka-2 no-144, futhi ikhebuli yesibhafa esiqinile enenombolo enkulu yama-cores ngokuyisisekelo yakhiwa ama-cores angu-6 noma angu-12 njengeyunithi eyisisekelo.
Ngenxa yezici ezihlukile zokusebenza kwekhebula leshubhu elixegayo elingu-250μm kanye nekhebula leshubhu eliqinile elingu-900μm, ukusetshenziswa kokubili nakho kuhlukile. Ikhebula leshubhu elingu-250μm lilungele izindawo ezinokhahlo futhi lisetshenziswa kabanzi ngaphandle. Uma kuqhathaniswa nekhebula le-optical 900μm tight-buffer optical, ikhebula le-loose-buffer optical 250μm linamandla aqinile aqinile, ukumelana nomswakama kanye nokumelana nokushisa okuphezulu, futhi ifanele izindawo ezinokushintsha kwezinga lokushisa kanye nomswakama ophezulu. Nokho, uma yeluliwe kakhulu, izokhipha umongo ejeli. Futhi, ikhebuli engu-250µm loose-tube ingase ingabi inketho enhle uma kudingeka umzila ozungeze ukugoba okuningi.
