Tib -Mod vs Multimode - thiab Xim Codes
Qhov thib ob axis yog hom fiber ntau, thiab nws tsis yog - sib tham tau: ib qho - hom pigtail spliced mus rau ib tug multimode cable (los yog vice versa) ua ib tug siab - poob, tsis ruaj tsis khov. Muab cov pigtail fiber ntau rau cable fiber ntau raws nraim.
Tib -mode pigtails (OS1 / OS2)
A 9/125 µm core, siv rau ntev -nruab deb thiab tag nrho PON / FTTH nkag mus ua haujlwm, ua haujlwm ntawm 1310 nm thiab 1550 nm (thiab 1490 / 1577 nm rau GPON / XGS-PON downstream). Tib hom - hom yog qhov loj tshaj plaws ntawm pigtail xav tau vim tias kev nkag mus thiab kev thauj mus los yog ib hom - hom. Tso- sab pigtails yuav tsum sivkhoov-insensitive G.657.A2 fiber ntau (ITU-T G.657.A2), uas zam lub 7.5 hli ntev - lub sij hawm khoov vojvoog - qhov tseem ceeb hauv lub kaw ntom nti slack coils ntawm lub thawv me me, qhov twg tus qauvG.652.Dfiber ntau (30 mm radius) yuav macrobend thiab ua rau lub teeb liab poob.
Multimode pigtails (OM1-OM5)
A 50/125 µm core (OM2–OM5) lossis legacy 62.5/125 µm (OM1), siv luv luv - ncav cuag cov ntaub ntawv -center thiab hauv - tsev txuas. OM3 thiab OM4 yog lub laser - qib optimized rau 10G / 40G / 100G nyob rau hauv luv luv; OM5 ntxiv luv -wave division multiplexing (SWDM). Daim ntawv ceeb toom tseem ceeb tshaj plaws: OM1's 62.5 µm core yuav tsis splice huv si rau 50 µm OM2/3/4 fiber ntau - cov tub ntxhais- txoj kab uas hla tsis sib haum ib leeg ua rau poob loj, ywj siab ntawm splice zoo.
Xim codes - nyeem lub tsho thiab khau raj
Jacket thiab connector- xim khau raj yog qhov shorthand rau fiber ntau hom thiab polish. Lawv ua rawsANSI/TIA-598-Cthiab tsim nyog ua rau lub cim xeeb - lawv tiv thaiv qhov tsis sib haum xeeb feem ntau ua ntej lub splicer txawm siv rau.
| Fiber hom | Core (µm) | Jacket xim | Hom kev siv |
|---|---|---|---|

| Multimode OM1 | 62.5/125 | Txiv kab ntxwv | LAN qub |
| Multimode OM2 | 50/125 | Txiv kab ntxwv | Legacy 1G LAN |
| Multimode OM3 | 50/125 | Aqua | 10G data center |
| Multimode OM4 | 50/125 | Aqua (los yog violet) | 40G/100G luv- ncav cuag |
| Multimode OM5 | 50/125 | Txiv qaub ntsuab | SWB 100 G |
Independent ntawm lub tsho xim, lubconnector khau rajencodes polish rau ANSI / TIA-598-C:xiav=ib zaug - hom UPC, ntsuab=ib zaug - hom APC, beige/dub=multimode. Qhov no yog tus ceev tshaj ceev tiv thaiv ib qho kev ua txhaum pigtail phem tshaj plaws -mating APC connector rau UPC chaw nres nkoj.Lub 8℃angled APC endface lub cev tsis tuaj yeem zaum tiv thaiv lub tiaj UPC endface; yuam nws puas ferrules thiab txhaj loj poob. Ntsuab khau looj plab hlaub tsuas yog ntsuab. Peb npog vim li cas PON xav tau APC hauvkev poob.
Jacket Material thiab Cable Structure
Feem ntau pigtails yog900 µm nruj-buffer- ib qho fiber ntau nyob rau hauv ib qho kev tiv thaiv tsis zoo, qee zaum nrog ib feem ntawm lub tsho sab nrauv uas tau stripped rov qab ua ntej lub splice. Qhov no yog tus qauv tsim vim tias pigtail nyob tiv thaiv hauv lub tais. Qhov twg ib tug pigtail yuav tsum tau tuav los yog taug kev nruj dua, 2.0 mm lossis 3.0 mm jacketed tsim muaj.
Jacket compound - phim nws rau ib puag ncig thiab hluav taws kub
- PVC (OFNR riser):economical default rau kev siv sab hauv tsev. Hloov tau yooj yim, tus nqi qis, tab sis tso pa tawm cov pa phem hnyav thaum hlawv - tsis tso cai hauv huab cua- tuav cov chaw plenum.
- LSZH (Low Smoke Zero Halogen):txoj kev xaiv zoo rau cov tsev nyob, tunnels, kev thauj mus los, thiab ib qho chaw nyob ib puag ncig uas cov pa luam yeeb muaj kuab lom yog lub neej - kev txhawj xeeb txog kev nyab xeeb. Tam sim no qhov kev qhia tshwj xeeb rau feem ntau European thiab ntau Asian sab hauv tsev installation.
- PE (Polyethylene):UV- thiab ya raws- tiv taus rau sab nraum zoov lossis raug kev tawm mus. Tsis tshua muaj tshwm sim ntawm pigtails tshwj xeeb - pigtails feem ntau zaum sab hauv tsev hauv lub tais - tab sis tau teev tseg qhov chaw pigtail raug nthuav tawm ua ntej txiav.
Ntau-fiber pigtails tuaj ua ibpob(cov xim ntawm tus kheej-coded 900 µm fibers hauv ib lub raj sab nraud) lossisribbon(cov fibers tuav hauv ib qho chaw tiaj tus rau pawg-fusion splicing). Ribbon pigtails khub nrog ib pawg - fusion splicer los txiav 12 fibers hauv ib qho kev sib tw - ib qho tseem ceeb ua haujlwm txuag hauv siab - suav qaum.
Yuav ua li cas Splice ib Fiber Pigtail, Kauj Ruam los ntawm kauj ruam
Ob txoj kev sib txuas yog siv hauv kev xyaum.Fusion splicingmelts ob lub iav xaus ua ke nrog ib qho hluav taws xob arc, muab ib qho kev sib koom ua ke mus tas li (~ 0.05 dB raug cuam tshuam,FOAkev taw qhia).Mechanical splicingaligns cov cleaved xaus nyob rau hauv ib qho Performance index - sib piv V- zawj thiab clamps lawv - sai dua los teeb tab sis siab dua (0.2–0.5 dB typical) thiab tsis ruaj khov ntev - lub sij hawm. Rau ib zaug - hom PON lossis kev thauj mus los, fusion yog tus qauv; mechanical splices yog nyob rau hauv ib ntus lossis kev kho thaum muaj xwm ceev nkaus xwb.
Fusion splice txheej txheem
- Xaub lub tshav kub-shrink tes tsho ua ntej.Xov tus tiv thaiv mus rau ib qho fiber ntauua ntejstripping - tsis nco qab nws txhais tau tias re- txiav tom qab qhov sib txuas. Fais fab thiab sov so lub splicer.
- Tshem cov coatings.Tshem tawm 900 µm tsis thiab 250 µm acrylate txheej hauv me me uas siv qhov tseeb notch ntawm lub cuab yeej sawb, nthuav tawm roughly 30 mm ntawm liab qab 125 µm iav. Nicked fiber ntau yuav tawg tom qab nyob rau hauv thermal cycling - strip huv si los yog re- sawb.
- Ntxuav lub khob liab qab.So cov liab qab fiber ntau ruaj nrog lint -dawb so wetted nrog 99% isopropyl cawv. Ib qho fiber ntau huv ua rau faint squeak. Invisible contamination ua npuas los yog qhov chaw tsaus nyob rau hauv lub splice thiab elevated poob.
- Cleev.Siv ib tug precision cleaver los tsim ib tug ca, perpendicular endface. Lub kaum sab xis tsis zoo yog qhov ua rau muaj kev sib tw siab siab - re-cleave es tsis ua rau lub ntsej muag tsis zoo.
- Load thiab fuse.Zaum ob lub fibers nyob rau hauv lub splicer V-grooves, kaw lub hau, thiab khiav lub arc. Ib qho tseem ceeb -aligning splicer qhia txog qhov kwv yees qhov poob; Lub hom phiaj Tsawg dua los yog sib npaug rau 0.05 dB ntawm kev sib tw ib leeg - hom fiber ntau (ib txwm; raws li FOA kev taw qhia rau fusion splice rau pigtail).
- Tiv thaiv kev sib koom tes.Swb lub tshav kub-shrink tes tsho tshaj lub liab qab splice kom lub sib koom ua ke nyob rau hauv lub hauv paus ntawm lub stainless reinforcement pas nrig, ces shrink nws nyob rau hauv lub splicer lub qhov cub. Lub fused sib koom ua ke tsis yooj yim li cov iav xov kom txog thaum tiv thaiv.
- Muab tso rau hauv lub tais.Coil slack saum toj kawg nkaus lub vojvoog khoov (Ntau dua lossis sib npaug ntawm 7.5 hli rau G.657.A2, Ntau dua lossis sib npaug li 30 hli rau G.652.D), zaum lub tes tsho hauv nws lub hnab, thiab xa cov khoom txuas mus rau lub vaj huam sib luag adapter. Lub kaw ntom nti yog macrobend poob koj yuav caum tom qab.
Yog hais tias tus splicer poob kwv yees siab, qhov txhaum yog yuav luag txhua zausdej ntwsntawm lub arc: qias neeg fiber, phem cleave, los yog txheej txheej.Re-cleave thiab re- huv si ua ntej yuav liam tus splicer los yog pigtail.Re-spling ntawm lub rooj zaum raug nqi feeb; ib qho siab - poob sib koom tshawb pom tom qab lub thawv kaw raug nqi tsheb thauj khoom.

Ib txoj hlua txuas txuas ob qhov chaw nres nkoj uas twb muaj lawm; ib tug pigtail tsim ib qho chaw nres nkoj los ntawm muab ib tug spliced cable fiber ib connector. Koj tuaj yeem txiav cov hlua duplex hauv ib nrab los ua ob lub pigtails - ib qho kev paub luv luv - tab sis lub hom phiaj - ua 900 µm pigtail yog slimmer thiab zoo dua haum rau lub tais.
Q: Dab tsi connector hom fiber pigtails tuaj?
A: LC, SC, FC, ST, E2000, thiab MPO/MTP. SC dominates FTTH/PON nkag, LC dominates siab -cov ntaub ntawv ceev- nruab nrab vaj huam sib luag, FC suits vibration- nquag thiab xeem daim ntawv thov, ST yog legacy multimode, E2000 ntxiv ib tug tiv thaiv shutter rau telecom thiab siab - fais fab txuas, thiab MPO 10 G / 4 fiber ntau ib zaug rau 20G pob txha.
Q: Dab tsi yog qhov txawv ntawm ib leeg -hom thiab multimode pigtails?
A: Tib - hom pigtails siv 9/125 µm tub ntxhais (lub tsho daj, OS1/OS2) rau kev ncua deb thiab tag nrho PON / FTTH ua haujlwm. Multimode pigtails siv 50/125 µm core (OM2–OM5) lossis legacy 62.5/125 µm (OM1) luv luv- ncav cuag cov ntaub ntawv-cov txuas hauv nruab nrab - OM3/OM4 yog aqua, OM5 txiv qaub ntsuab, OM1/OMIA8-txiv kab ntxwv, Ob hom tsis sib hloov; splicing hla qib fiber ntau ua rau poob siab.
Q: Yuav ua li cas koj splice lub fiber pigtail?
A: Xaub lub tshav kub-shrink protector ua ntej, strip lub 900 µm tsis thiab 250 µm txheej kom nthuav tawm ~ 30 hli ntawm iav liab qab, huv si nrog 99% isopropyl cawv, cleave ib tug tiaj tus endface, fuse nyob rau hauv ib tug core -aligning splicer (lub hom phiaj tsawg tshaj li 0.0) los yog sib npaug sib koom ua ke, cua sov-shrink nws, thiab coil lub slack nyob rau hauv lub tais saum toj no qhov tsawg kawg nkaus khoov vojvoog. Mechanical splicing yog ib qho kev xaiv rau kev ua haujlwm kub ntxhov tab sis khiav 0.2-0.5 dB thiab tsis ruaj khov.
Q: Vim li cas PON thiab FTTH pigtails siv SC / APC?
A: APC's 8℃angled polish deflects reflected lub teeb rau hauv cladding, muab rov qab poob qis dua -60 dB. GPON thiab XGS-PON lasers (ib ITU-T G.984 thiab G.9807.1) yog rhiab rau rov qab-reflection, thiab UPC (~−50 dB) tsis txaus - nws destabilizes lub laser. SC ua haujlwm zoo nrog cov hnab looj tes hauv thaj teb, yog li SC / APC (khau raj ntsuab) yog FTTH default. Ib qho tag nrho -APC infrastructure kuj haum rau yav tom ntej GPON-rau-XGS-PON hloov kho yam tsis tau rov ua dua.
Q: Kuv puas tuaj yeem ua phooj ywg APC pigtail nrog UPC txuas?
A: Tsis yog. Lub 8℃angled APC endface tsis tuaj yeem zaum tawm tsam lub tiaj UPC endface; yuam lawv puas ferrules thiab txhaj loj insertion poob. Cov xim khau raj yog kev tiv thaiv - ntsuab (APC) cov phooj ywg tsuas yog ntsuab, xiav (UPC) cov phooj ywg tsuas yog xiav. Tsis txhob sib tov polishes.
Q: Dab tsi yog qhov cuam tshuam tsis zoo ntawm fiber ntau pigtail?
A: Ib qho fusion splice rau pigtail ntxiv txog 0.05 dB (ib txwm), thiab lub hom phiaj sib txuas sib txuas tsawg dua lossis sib npaug rau 0.3 dB hauv thaj teb (ib IEC 61300-3-34). Factory tshuab- polished ib hom pigtails feem ntau xa khoom tsawg dua lossis sib npaug rau 0.2 dB qhov poob thiab Tsawg dua lossis sib npaug rau −60 dB rov poob rau ib qhov txuas. Ib qho kev nyeem ntawv siab tshaj 0.5 dB ntawm ib qho kev sib txuas lus yuav luag ib txwm muaj kev sib kis kab mob - huv si thiab tshuaj xyuas ua ntej hloov kho vajtse.
Q: Kuv yuav ua li cas thiaj kuaj tau cov fiber ntau pigtail?
A: Ua ntej splicing, tshuaj xyuas lub Hoobkas connector endface nrog 400 × fiber ntau soj ntsuam, xyuas tag nrho plaub IEC 61300-3-35 zones (core, cladding, nplaum, tiv tauj). Tom qab splicing, ntsuas txhua qhov kev tshwm sim splice nrog OTDR (lub hom phiaj Tsawg dua lossis sib npaug ntawm 0.05 dB) thiab xaus -rau- xaus qhov kev poob qis nrog lub ntsuas hluav taws xob ntsuas thiab lub teeb pom kev (lub hom phiaj tsawg dua lossis sib npaug rau 0.3 dB ib khub niam txiv). Ib qho kev sib txuas nyeem ntawv saum toj no 0.5 dB qhia tias muaj kab mob sib kis - ntxuav lub ntsej muag thiab rov kuaj dua ua ntej kaw lub qhov rooj. Sau txhua qhov ntsuas tiv thaiv fiber ntau ID thiab hnub tim.
