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.Nokho, kusenomehluko phakathi kwalokhu okubili, okuqukethwe esakhiweni, umsebenzi, izinzuzo, ukungalungi, njll., okwenza kokubili kuhluke ekusetshenzisweni.
Endabeni ye-loose-tube fibre, ifakwa nge-helically ku-semi-rigid tube, okuvumela ikhebula ukuba 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, amanye amakhebuli okubona ngokuvamile akhiwa ama-cores 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 ku-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.
