Imiyoboro ya optique yo mu nzu ikoreshwa cyane muri sisitemu yububiko. Bitewe nibintu bitandukanye nko kubaka ibidukikije nuburyo bwo kwishyiriraho, gushushanya insinga za optique zo murugo byabaye ingorabahizi. Ibikoresho bikoreshwa muri fibre optique hamwe ninsinga biratandukanye, hamwe nibikoresho bya mehaniki na optique byibandwaho muburyo butandukanye. Intsinga isanzwe yo mu nzu irimo insinga imwe-shami yinsinga, insinga zidafunze, hamwe ninsinga zifunze. Uyu munsi, ISI imwe izibanda kuri bumwe muburyo busanzwe bwinsinga za optique: GJFJV.
GJFJV Umugozi wo mu nzu
1. Imiterere yimiterere
Inganda-isanzwe yerekana insinga zo mu nzu ni GJFJV.
GJ - Itumanaho ryimbere mu nzu
F - Ibikoresho bidafite imbaraga
J - Imiterere ya fibre optique
V - Polyvinyl chloride (PVC) icyatsi
Icyitonderwa: Kubyerekeye ibikoresho byitwa amazina, "H" bisobanura umwotsi muke wa halogene utagira umwotsi, naho "U" bisobanura icyatsi cya polyurethane.
2. Igishushanyo mbonera cyo mu nzu Igishushanyo mbonera
Ibikoresho byo guhimba nibiranga
1.
Fibre optique ikozwe mubikoresho bya silika, naho diameter isanzwe yambarwa ni 125 mm. Diameter yibanze ya moderi imwe (B1.3) ni 8,6-9.5 mm, naho kuri moderi nyinshi (OM1 A1b) ni 62.5 mm. Diameter yibanze ya OM2 (A1a.1), OM3 (A1a.2), OM4 (A1a.3), na OM5 (A1a.4) ni 50 mm.
Mugihe cyo gushushanya fibre optique ya fibre optique, hashyirwaho urwego rwa elastique ukoresheje urumuri ultraviolet kugirango wirinde kwanduza umukungugu. Iyi shitingi ikozwe mubikoresho nka acrylate, rubber silicone, na nylon.
Igikorwa cyo gutwikira ni ukurinda fibre optique hejuru yubushuhe, gaze, no gukanika imashini, no kuzamura imikorere ya mikorobe ya fibre, bityo bikagabanya igihombo cyunamye.
Igifuniko gishobora kuba amabara mugihe cyo gukoresha, kandi amabara agomba guhuza na GB / T 6995.2 (Ubururu, Orange, Icyatsi, Umuhondo, Icyatsi, Umweru, Umutuku, Umukara, Umuhondo, Umutuku, Umutuku, cyangwa Cyan Icyatsi). Irashobora kandi kuguma idafite ibara nkibisanzwe.
2. Gufata neza Buffer
Ibikoresho: Ibidukikije byangiza ibidukikije, flame-retardant polyvinyl chloride (PVC),umwotsi muke halogen-(LSZH) polyolefin, Umugozi wa OFNR wagizwe na flame-retardant kabel, umugozi wa OFNP-flame-retardant.
Imikorere: Irinda kandi fibre optique, ikemeza guhuza n'imiterere itandukanye yo kwishyiriraho. Itanga kurwanya impagarara, kwikanyiza, no kunama, kandi ikanatanga amazi nubushuhe.
Koresha: Igice cya buffer gifatika gishobora kuba ibara-kode kugirango imenyekane, hamwe na code yamabara ihuye na GB / T 6995.2. Kubiranga bitamenyerewe, impeta yamabara cyangwa utudomo birashobora gukoreshwa.
3. Gushimangira Ibigize
Ibikoresho:Aramid yarn, cyane cyane poly (p-phenylene terephthalamide), ubwoko bushya bwa tekinoroji yo mu rwego rwo hejuru. Ifite ibintu byiza cyane nka ultra-high strength, modulus nyinshi, irwanya ubushyuhe bwinshi, aside na alkali irwanya, yoroheje, izirinda, irwanya gusaza, hamwe nigihe kirekire cyo gukora. Ku bushyuhe bwo hejuru, bugumana ituze, hamwe nigabanuka rito cyane, kugabanuka kwinshi, hamwe nubushyuhe bwo hejuru bwikirahure. Itanga kandi ruswa irwanya ruswa kandi idakora neza, bigatuma iba ibikoresho byiza byubaka insinga za optique.
Imikorere: Urudodo rwa Aramide ruzengurutswe neza cyangwa rushyizwe mu burebure mu cyuma cy’umugozi kugira ngo rutange inkunga, rwongerera umurongo insinga n’umuvuduko ukabije, imbaraga za mashini, ituze ry’umuriro, hamwe n’imiti ihamye.
Ibi biranga byemeza imikorere ya kabili hamwe nubuzima bwa serivisi. Aramide nayo ikoreshwa muburyo bwo gukora amasasu atagira amasasu na parasite kubera imbaraga zayo zidasanzwe.
4. Urupapuro rwo hanze
Ibikoresho: Umwotsi muke halogen-udafite flame-retardant polyolefin (LSZH), polyvinyl chloride (PVC), cyangwa insinga za OFNR / OFNP zashyizwe kumurongo. Ibindi bikoresho byicyatsi birashobora gukoreshwa nkuko abakiriya babisabwa. Umwotsi muke wa halogene udafite polyolefin ugomba kuba wujuje ibipimo bya YD / T1113; polyvinyl chloride igomba kubahiriza GB / T8815-2008 kubikoresho byoroshye bya PVC; thermoplastique polyurethane igomba kuba yujuje ibipimo bya YD / T3431-2018 kuri elastomers ya termoplastique polyurethane.
Imikorere: Urupapuro rwinyuma rutanga ubundi burinzi kuri fibre optique, yemeza ko ishobora guhuza nibidukikije bitandukanye. Itanga kandi kurwanya impagarara, kwikanyiza, no kunama, mugihe itanga amazi nubushuhe. Kubireba umutekano muke cyane, ibikoresho bidafite umwotsi wa halogene bikoreshwa mukuzamura umutekano wumugozi, kurinda abakozi imyuka yangiza, umwotsi, numuriro mugihe habaye umuriro.
Koresha: Ibara ryurupapuro rugomba guhuza na GB / T 6995.2. Niba fibre optique ari ubwoko bwa B1.3, sheath igomba kuba umuhondo; kubwoko bwa B6, sheath igomba kuba umuhondo cyangwa icyatsi; kubwoko bwa AIa.1, bugomba kuba orange; Ubwoko bwa AIb bugomba kuba imvi; Ubwoko bwa A1a.2 bugomba kuba cyan icyatsi; na A1a.3-ubwoko bugomba kuba bwijimye.
Gusaba
. Byongeye kandi, insinga zo mu nzu zishobora gukoreshwa mu nsinga zo mu rugo, nka LAN na sisitemu yo mu rugo ifite ubwenge.
2. Gukoresha: insinga za optique zo mu nzu ziroroshye, zoroheje, kuzigama umwanya, kandi byoroshye gushiraho no kubungabunga. Abakoresha barashobora guhitamo ubwoko butandukanye bwinsinga za optique zishingiye kumurongo usabwa.
Mu ngo zisanzwe cyangwa mu biro, insinga za PVC zo mu nzu zirashobora gukoreshwa.
Ukurikije ibipimo ngenderwaho byigihugu GB / T 51348-2019:
①. Inyubako rusange zifite uburebure bwa 100m cyangwa zirenga;
②. Inyubako rusange zifite uburebure buri hagati ya 50m na 100m n'ubuso burenga 100.000㎡;
③. Ibigo byamakuru ya B cyangwa hejuru;
Ibi bigomba gukoresha insinga ya flame-retardant optique ifite igipimo cyumuriro kitari munsi yumwotsi muke, halogen idafite B1 urwego.
Mubisanzwe UL1651 muri Reta zunzubumwe zamerika, ubwoko bwa kabili burenze urugero bwa flame-retardant ni umugozi wa optique wa OFNP, wagenewe kwizimya muri metero 5 mugihe uhuye numuriro. Byongeye kandi, ntabwo irekura umwotsi wubumara cyangwa imyuka, bituma ikenerwa gushyirwaho mumiyoboro ihumeka cyangwa sisitemu yo kugarura ikirere ikoreshwa mubikoresho bya HVAC.
