Ikhebula le-optical elingcwatshwe ngokuqondile liboshwe nge-tape yensimbi noma ucingo lwensimbi ngaphandle, futhi ligqitshwe ngokuqondile emhlabathini.Kudinga ukusebenza kokumelana nokulimala kwangaphandle kwemishini nokuvimbela ukugqwala kwenhlabathi.Izakhiwo ezihlukene ze-sheath kufanele zikhethwe ngokuya ngezindawo ezisetshenziswayo nezimo ezahlukahlukene.Isibonelo, ezindaweni ezinezinambuzane namagundane, kufanele kukhethwe ikhebula le-optical elinesheath elivimbela izinambuzane namagundane ukuba zingalunywa.Ngokuya ngekhwalithi yenhlabathi nendawo, ukujula kwentambo yokubona egqitshwe ngaphansi ngokuvamile kuphakathi kuka-0.8m no-1.2m.Lapho ubeka, kufanele futhi kuqashelwe ukugcina i-fiber strain ngaphakathi kwemingcele evumelekile.
Ukungcwatshwa okuqondile kufanele kuhlangabezane nezidingo ezilandelayo:
1. Gwema izindawo ezine-asidi eqinile kanye nokugqwala kwe-alkali noma ukugqwala okukhulu kwamakhemikhali;uma zingekho izinyathelo zokuvikela ezihambisanayo, gwema izindawo zokulimala komhlwa kanye nezindawo ezithintwa imithombo yokushisa noma izindawo ezilinyazwa kalula amandla angaphandle.
2. Ikhebula le-optical kufanele libekwe emseleni, futhi indawo ezungezile yekhebula le-optical kufanele imbozwe ngenhlabathi ethambile noma ungqimba lwesihlabathi olunogqinsi olungekho ngaphansi kuka-100mm.
3. Kubo bonke ubude bekhebula le-optical, ipuleti elivikelayo elinobubanzi obungekho ngaphansi kuka-50mm ezinhlangothini zombili zekhebula le-optical kufanele limbozwe, futhi ipuleti yokuzivikela kufanele yenziwe ngokhonkolo.
4. Indawo yokubeka isezindaweni ezimbiwa njalo njengemigwaqo engenela emadolobheni, engabekwa ngamabhande adonsa amehlo ebhodini lokuvikela.
5. Endaweni yokubeka endaweni engasedolobheni noma endaweni evulekile, endaweni yomugqa oqondile ongaba ngu-100mm eduze kwendlela yekhebula le-optical, endaweni yokujika noma engxenyeni ehlangene, izimpawu zokuma noma izigxobo ezisobala kufanele zimiswe.
6. Uma ubeka ezindaweni zenhlabathi ezingaqandisiwe, umgodla wekhebula le-optical esisekelweni sesakhiwo esingaphansi komhlaba akufanele ube ngaphansi kuka-0.3m, futhi ukujula kwe-optical cable sheath emhlabathini akumele kube ngaphansi kuka-0.7m;lapho itholakala endleleni yomgwaqo noma inhlabathi etshaliwe, kufanele ijule kahle, futhi akufanele ibe ngaphansi kuka-1m.
7. Uma ubeka endaweni yenhlabathi efriziwe, kufanele ingcwatshwe ngaphansi kwesendlalelo senhlabathi efriziwe.Uma ingakwazi ukungcwatshwa ngokujulile, ingangcwatshwa emhlabathini owomile oqandisiwe noma umhlabathi ogcwele amanzi ngokugeleza okuhle komhlabathi, nezinye izinyathelo zokuvimbela ukulimala kwekhebula le-optical nazo zingathathwa..
8. Uma izintambo zekhebula ezicwebezelayo ezigqitshwe ngokuqondile ziphambana nojantshi, imigwaqo emikhulu noma imigwaqo, amapayipi okuvikela kufanele agqokwe, futhi ububanzi bokuvikela kufanele budlule umbhede womgwaqo, izinhlangothi zombili zomgwaqo ogandayiwe kanye nohlangothi lomsele wokudonsa amanzi ngaphezu kuka-0.5m.
9. Lapho ikhebula le-optical elingcwatshwe ngokuqondile lifakwa esakhiweni, ishubhu elivikelayo kufanele libekwe emgodini odlulayo, futhi umlomo wombhobho kufanele uvinjwe ngamanzi.
10. Ibanga elicacile phakathi kwejoyinti lentambo yokubona egqitshwe ngokuqondile kanye nekhebula lokubona eliseduze akufanele libe ngaphansi kuka-0.25m;izikhundla ezihlangene zezintambo ezibonakalayo ezihambisanayo kufanele zinyakaze ukusuka komunye nomunye, futhi ibanga elicacile akufanele libe ngaphansi kuka-0.5m;indawo ehlangene endaweni yemithambeka kufanele ibe evundlile;kumasekhethi abalulekile Kunconywa ukuthi ushiye indlela eyisipele yokubeka ikhebula le-optical esigabeni sendawo kusukela cishe ku-1000mm ezinhlangothini zombili ze-optical cable joint.
