Muaj ntau hom patch cords thiab pigtails. Nws yog tsim nyog sau cia tias fiber ntau pigtails thiab thaj qaum tsis yog lub tswv yim. Qhov sib txawv tseem ceeb ntawm fiber ntau optic thaj qaum thiab fiber ntau optic pigtails yog tias tsuas yog ib qho kawg ntawm fiber optic pigtail muaj ib qho kev sib txuas, thiab ob ntu ntawm thaj qaum muaj cov khoom sib txuas. Hauv cov ntsiab lus yooj yim, thaj qaum tuaj yeem muab faib ua ob thiab siv los ua pigtail.
1.Dab tsi yog jumpers thiab pigtails?
Jumpers yog cov kab txuas ncaj qha rau cov khoos phis tawj lossis cov khoom siv los pab txhawb kev sib txuas thiab kev tswj hwm. Jumpers muaj cov txheej tiv thaiv tuab dua thiab feem ntau yog siv los ntawm cov thawv davhlau ya nyob twg thiab cov khoom siv kho qhov muag.
Tsuas yog ib qho kawg ntawm lub pigtail muaj qhov txuas, thiab lwm qhov kawg yog qhov sib txuas ntawm fiber ntau optical, uas txuas nrog lwm cov fiber ntau optical cores nyob rau hauv daim ntawv ntawm fusion splicing, uas feem ntau tshwm nyob rau hauv optical fiber terminal box.
2.Type ntawm optical fiber jumpers
Optical fiber jumpers tau muab faib ua ib hom fiber ntau jumpers thiab ntau hom fiber ntau jumpers hauv cov ntaub ntawv xa khoom. Ib hom fiber ntau jumpers feem ntau yog daj, connectors thiab lub tes tsho tiv thaiv yog xiav, wavelength yog 1310nm / 1550nm, thiab kis nrug deb yog 10km / 40km, ntev kis tau tus mob; multimode fiber jumper: feem ntau txiv kab ntxwv los yog pas dej xiav, lub connector thiab tiv thaiv npog yog beige los yog dub, lub wavelength yog 850nm, kis tau tus mob nrug yog 500m, thiab kis tau tus mob deb yog luv.
Fiber thaj qaum feem ntau tuaj yeem muab faib ua hom hauv qab no raws li hom txuas:
①LC hom optical fiber ntau jumper: square connector, ua los ntawm ib qho yooj yim-rau-ua haujlwm modular jack (RJ) latch mechanism, yog ib tug connector rau txuas SFP optical modules, feem ntau siv nyob rau hauvrouters.
②SC hom kho qhov muag fiber ntau jumper: duab plaub sib txuas, siv plug-in bolt hom fastening txoj kev, yog lub connector rau txuas GBIC optical module, thiab feem ntau siv nyob rau hauvroutersthiabhloov.
③ST hom kho qhov muag fiber ntau jumper: puag ncig lub taub hau txuas, fastened los ntawm cov ntsia hlau buckle, feem ntau siv rau optical fiber tis ncej.
④FC-hom optical fiber jumper: ncig optical fiber connector, sab nraud yog ua los ntawm cov khoom siv hlau, thiab nws kuj tseem fastened los ntawm turnbuckles, feem ntau siv rau sab ODF.
⑤ MPO-hom optical fiber jumper: Nws yog tsim los ntawm ob lub high-precision yas molded connectors thiab optical cables. Nws tau lees txais cov miniaturized tsim thiab muaj qhov ntom ntom loj thiab ruaj khov thiab txhim khu kev qha.
⑥MTP hom fiber ntau kho qhov muag cords: fiber ntau thaj cords nrog ntau tus cores thiab me me yog siv nyob rau hauv high-density integrated optical fiber kab ib puag ncig.
3.Lub hom pigtail
Zoo li fiber ntau jumpers, pigtails tau muab faib ua ib hom pigtails thiab ntau hom pigtails raws li hom fiber ntau. Sab nrauv ntawm ib hom pigtails yog daj, nrog lub wavelength ntawm 1310nm / 1550nm, thiab kis tau tus mob mus txog 10km / 40km. Kev sib txuas mus ntev; Cov txheej txheej ntawm ntau hom pigtail yog txiv kab ntxwv / pas dej xiav, lub wavelength yog 850nm, thiab kis tau tus mob yog 500m. Nws yog siv rau kev sib txuas luv luv. Cov fiber ntau jumpers thiab pigtails muab los ntawm ETU-LINK muaj ntau hom kev xaiv los ntawm.
Pigtails feem ntau tuaj yeem muab faib ua hom hauv qab no raws li hom txuas:
①LC-hom pigtail connector: Qhov luaj li cas ntawm tus pin thiab lub tes tsho ntawm LC-hom pigtail connector yog ib nrab ntawm cov saum toj no ob connectors, uas txhim kho qhov chaw siv ntawm optical tis ncej. Nws siv lub jack modular uas yooj yim rau kev khiav lag luam. (RJ) Lub hauv paus ntsiab lus ntawm latching yog tsim.
②SC-hom pigtail connector: Nws yog tsim los ntawm cov khoom siv yas engineering, tus nqi pheej yig, lub plhaub yog cov duab plaub, cov pins ntawm cov mating kawg nto feem ntau yog PC lossis APC-hom sib tsoo txoj kev, thiab kho txoj kev yog plug-in latch. hom, uas yooj yim rau kev khiav lag luam thiab tsis yooj yim rau oxidize.
③ST-type pigtail connector: Sib txawv ntawm SC-type pigtail connector, cov tub ntxhais ntawm ST-type pigtail connector raug nthuav tawm thaum cov tub ntxhais ntawm SC-type pigtail connector nyob rau hauv lub connector. Feem ntau, ST yog siv nyob rau hauv 10Mbps Ethernet system. Hom pigtail connector, SC hom pigtail connector yog siv nyob rau hauv 10Mbps Ethernet.
④FC-hom pigtail connector: tseem hu ua round threaded connector, nws yog ua los ntawm cov hlau thiab muaj zoo durability. Nws yog feem ntau siv rau thaj panels.
4.Kev thov ntawm jumpers thiab pigtails
Jumpers feem ntau yog siv rau kev sib txuas ntawm optical fiber faib thav duab lossis optical fiber ntau qhov (socket) thiab covhloov, kev sib txuas ntawm covhloovthiab covhloov, kev sib txuas ntawm covhloovthiab lub khoos phis tawj desktop, thiab kev sib txuas ntawm cov ntaub ntawv kho qhov muag fiber ntau thiab lub khoos phis tawj desktop. Rau kev tswj hwm, khoom siv chav thiab chaw ua haujlwm subsystems.
Pigtails feem ntau yog siv rau hauv kev sib txuas lus kho qhov muag, kho qhov muag siv tes hauj lwm, cov ntaub ntawv kho qhov muag kis tau tus mob, kho qhov muag CATV, thaj chaw hauv cheeb tsam (LAN), cov cuab yeej kuaj xyuas, cov khoom siv kho qhov muag, cov servers serial, FTTH / FTTX, kev sib txuas lus sib txuas thiab kev teeb tsa ua ntej.
5.Kev ceev faj rau jumpers thiab pigtails
① Lub transceiver wavelengths ntawm optical modules txuas nrog jumper yuav tsum yog tib yam. Feem ntau, cov khoom siv kho qhov muag luv luv yog sib txuam nrog ntau hom jumpers, thiab cov khoom siv kho qhov muag ntev tau sib phim nrog ib hom jumpers kom ntseeg tau qhov tseeb ntawm cov ntaub ntawv xa mus.
② Lub jumper yuav tsum txo qis winding kom ntau li ntau tau thaum lub sij hawm xaim txheej txheem, thiaj li yuav txo tau qhov attenuation ntawm lub teeb liab optical thaum lub sij hawm kis tau tus mob.
③ Lub connector ntawm lub jumper yuav tsum huv si. Tom qab siv, lub connector yuav tsum tau muab kaw nrog ib tug tiv thaiv npog kom tsis txhob muaj roj thiab hmoov av nkag mus. Yog tias nws yog xim av, siv paj rwb swab dipped hauv cawv los ntxuav nws.
④ Lub pigtail yog qhov sib luag, thiab ntu ntu ntawm pigtail yog ntawm kaum ntawm 8 degrees. Nws tsis tiv taus qhov kub thiab txias yog tias nws siab tshaj 100 ° C. Yog li ntawd, tsis txhob siv nws nyob rau hauv ib puag ncig kub.
Optical fiber connectors yog ib feem tseem ceeb ntawm kev sib txuas lus fiber ntau optical. Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv kis tau tus mob, qhov zoo ntawm lub ferrule, ntau lawm technology thiab txoj kev tag nrho cov txiav txim siab stability ntawm cov ntaub ntawv kis tau tus mob.
