Fibre y'urumuri ikora ihererekanya ry'ibimenyetso binyuze mu kwerekana urumuri rw'urumuri rwa infrared ruri mu gice cy'imbere cya silica. Ibangamiwe no gutakaza ubushobozi bwo kwinjiza silika, gukwirakwira kwa Rayleigh, kwinjiza infrared no kugabanya imbaraga z'amazi ya hydroxyl, imigozi itandatu y'ubucuruzi ikoreshwa mu nganda z'itumanaho ku isi: 850 nm, 1310 nm, 1383 nm, 1490 nm, 1550 nm na 1625 nm. Iyi migozi ikubiyemo LAN y'intera ngufi, umuyoboro w'umujyi, umugongo w'amaguru maremare, uburyo bwo kugera kuri fibre ya PON, kongera ingufu z'urumuri n'ibintu byo gupima fibre y'urumuri. Hari itandukaniro ritandukanye mu buryo bwo kugabanya ingufu, gukwirakwira kwa chromatic, intera ntarengwa yo kohereza, guhuza ibice bya optoelectronic n'uburyo fibre itoranywamo hagati y'imigozi itandukanye, ibi bikaba ari ibipimo by'ibanze byo guhitamo fibre, igishushanyo mbonera cy'ubuhanga n'ubushakashatsi ku bice bya optical. Iyi nyandiko igizwe n'ibice bitatu by'ingenzi: imiterere irambuye y'imigozi itandatu, kugereranya imiterere ya tekiniki y'imigozi, no guhuza fibre n'uburyo bwo gushyira mu byiciro buri mugozi.
Igice cya 1 Ibiranga Ijwi ryimbitse ry'Imirongo itandatu y'itumanaho rya Fiber Classic
1.1 850 nm (Idirishya rigufi, Idirishya rya mbere ry'itumanaho ry'urumuri)
850 nm ni wo mubare wa mbere w’uburebure bw’itumanaho wakoreshejwe mu bucuruzi gusa kuri fibre optique ya multimode. Inkomoko yayo ikomeye y’igihombo ikomoka kuri Rayleigh scattering, aho igabanuka ryayo ringana n’ingufu za kane z’uburebure bw’uburebure. Bitewe n’uburebure bw’uburebure bw’uburebure bw’urumuri, igabanuka ry’urumuri risanzwe riri hagati ya 2.5 na 3.0 dB/km, urwego rwo hejuru rw’igihombo mu miyoboro itandatu y’urumuri. Nta gice cyo gutatanya kiri kuri 850 nm; ikwirakwira ry’ibintu hamwe n’ikwirakwira hagati y’imiyoboro bigabanya cyane impumuro z’urumuri kandi bikagabanya kugera ku ihererekanya. Kuri fibre multimode ya OM1 na OM2, intera ntarengwa ya Gigabit Ethernet ni metero 550 na metero 220 kuri 850 nm, mu gihe 10G Ethernet ishyigikira metero 33 (OM1) na metero 82 (OM2) gusa.
Laser zisohora ubuso zihagaze neza (VCSELs) ni isoko ry’urumuri risanzwe kuri uyu mugozi ufite ipaki nto, igiciro gito kandi nta kindi gisabwa mu gukonjesha. Uburemere buke bwo guhuza bugabanya cyane ikiguzi cyo kubaka sisitemu. Kubera ko ifite ubushobozi bwo kugabanya no gukwirakwiza ibintu, 850 nm igarukira ku nsinga zo mu nzu zigenda n'intera ngufi, zikoreshwa cyane mu guhuza ububiko bw'amakuru no mu buryo bw'insinga.
1.2 1310 nm (Idirishya rya Zero-Dispersion, Idirishya rya Kabiri ry'itumanaho)
Igenzurwa n’ibipimo ngenderwaho bya ITU-T, 1310 nm ni wo mubare w’uburebure bwa zero-dispersion kuri fibre ya G.652 imwe. Ikwirakwizwa ry’ibikoresho rirwanya ikwirakwizwa ry’umuraba kuri uyu mugozi, rigatanga ikwirakwizwa rya chromatic hafi ya zero hafi ya 0 ps/(nm·km) kandi rigakuraho ihindagurika ry’imitsi riterwa no gukwirakwizwa nta modules ziyongeraho zo gukwirakwizwa. Igabanuka ry’umuraba rigabanuka kuri 0.33 ~ 0.38 dB/km nta kintu kigaragara cyo gufata amazi ya hydroxyl, bigatuma iba amahitamo meza yo kohereza amakuru adafite aho ahuriye n’ingingo kugeza ku ngingo.
Laser ya Fabry-Perot (FP) niyo ikoresha ikoranabuhanga rya 1310 nm kandi igura ibice biciriritse. Ariko, ubu bunini bw'umurambararo burarenga urugero rwa EDFA (Erbium-Doped Fiber Amplifier), bityo kohereza amakuru mu ntera ndende bishingiye ku gukoresha amashanyarazi-optical relay aho gukoresha amashanyarazi yose. Uretse kohereza amakuru, 1310 nm ni bwo bunini bw'umurambararo bwa OTDR (Optical Time Domain Reflectometer), bukoreshwa ku isi hose mu kwakira insinga za fibre no kumenya aho ikibazo giherereye.
1.3 1383 nm (Idirishya ripima amazi, umugozi woroshye upima amazi make)
Fibre isanzwe ya G.652A/B ifite ions za OH⁻ zisigaye zavuye mu gukora preform, bigatuma uburebure bukomeye bwo kwinjiza bugera kuri 1383 nm hamwe no kugabanya uburebure bwa dB/km, byatumye ubu burebure bw'umurambararo butaboneka mu bucuruzi mu myaka ibarirwa muri za mirongo ishize. Kubera amazi menshi arenze urugero n'ikoranabuhanga rya synthetic preform kuri fibre ya G.652C/G.652D ifite amazi make, ubwinshi bwa ion za hydroxide zisigaye bugenzurwa ku rwego rwa ppb, bigagabanya igihombo cy'amazi kiri munsi ya 0.4 dB/km kandi bigatuma ubucuruzi bukwirakwira mu buryo bunini.
Umuvuduko uboneka ugizwe na 1360 ~ 1410 nm, wuzuza icyuho kiri hagati ya 1310 nm na 1490 nm kugira ngo umuyoboro wa CWDM wongererwe. Kimwe na 1310 nm, 1383 nm ntishobora kongerwa na EDFA, bigatuma ikoreshwa mu kwagura CWDM mu mujyi mu buryo buciriritse no mu kugenzura umutekano w’abikorera ku giti cyabo. Ubusanzwe, kugabanya umuvuduko biguma kuri 0.38 ~ 0.42 dB / km.
1.4 1490 nm (Aho batangira S-band, Uburebure bw'Umuraba wo munsi wa FTTH PON)
Ibarizwa muri S-band (1460 ~ 1530 nm), 1490 nm isobanurwa nk'uburebure bw'umurambararo busanzwe bwa EPON / GPON hakurikijwe protocole ya ITU-T G.984: OLT yohereza amakuru yo hasi kuri 1490 nm, mu gihe ONU yohereza ikimenyetso cyo kugaruka hejuru kuri 1310 nm, bigatuma habaho kohereza kwa fibre imwe mu cyerekezo kimwe binyuze mu gukwirakwiza umurambararo wa wavelength.
Ubusanzwe, ubushobozi bwo kugabanya 1490 nm buri hagati ya 0.26 na 0.30 dB/km, buri hejuru ya 1310 nm mu gutakaza umusaruro; ikoranabuhanga rya chromatic riguma kuri 10 ps/(nm·km), rigashyigikira icyuma gisanzwe cya PON ODN cya kilometero 20 nta ngaruka zo gukwirakwiza. Laser ya DFB ifite ubugari buto bwa spectral linewide hamwe n'ubushyuhe buhoraho ifite ibikoresho byo kohereza ibimenyetso bidakomeye nyuma yo gutandukanya optique. Akayunguruzo ka WDM gahuye gatandukanya ibimenyetso byo hejuru n'ibyo hasi, bigatuma 1490 nm iba uburebure bw'umurambararo bukoreshwa cyane mu kugera kuri internet ya internet ku isi hose.
1.5 1550 nm (C-band Core, Idirishya rya gatatu ry'itumanaho rigabanuka cyane)
Izwi nka "golden window of optique communication", 1550 nm iherereye muri C-band (1530 ~ 1565 nm), aho fibre silica igera ku rugero rwo hasi rwa 0.19 ~ 0.22 dB / km kuri wavebands esheshatu. Ubu bunini bw'umurambararo buhuye neza na gain spectrum ya EDFA; ubwinshi bwa DWDM optical carriers bushobora kongererwa icyarimwe hatabayeho kuvugururwa kwa optoelectronic, bigatuma ibirometero ibihumbi n'ibihumbi byoherezwa mu buryo burambye bidasubiramo.
Fibre isanzwe ya G.652 igaragaza uburyo bwo gukwirakwiza neza chromatic hafi ya 17 ps/(nm·km) kuri 1550 nm, bisaba DCF (Dispersion Compensation Fiber) kuri DWDM backbone ndende cyane. Fibre ya G.655 idahinduka ikomeza gukwirakwiza guto (2 ~ 6 ps/(nm·km)) kugira ngo ihagarike ingaruka za Four-Wave Mixing nonlinear effect, yakozwe neza kugira ngo sisitemu ya DWDM ikoreshwe ku bushobozi bwinshi. Uretse backbone intera ndende, 1550 nm ni wo mubare w'uburebure ukora gusa wo kohereza optique ya analog CATV RF; sisitemu ya DWDM igabanya C-band mo imiyoboro irenga 80 isanzwe ku ntera ya 0.8 nm kugira ngo ikore network ya backbone ndende cyane ndetse n'insinga za optique zo munsi y'amazi.
1.6 1625 nm (L-band, Uburebure bw'umuraba ugenzura fibre)
1625 nm igera kuri L-band (1565 ~ 1625 nm), ahanini yagenewe kugenzura fibre optique kuri interineti mu buryo bwihuse no kwagura ubushobozi bwa DWDM mu gice cya L-band. Ubusanzwe igabanuka ni 0.23 ~ 0.25 dB / km nta ntera y'amazi ibangamira, kandi ikwirakwira rya chromatic rigera kuri 22 ps / (nm · km).
Inyungu nyamukuru iri mu kwitandukanya kwa spectrum n'uburebure bw'umurambararo wa serivisi (1310/1490/1550 nm). Binyuze kuri passive WDM coupler, urumuri rukurikiranwa ruhuzwa na fibre ikora nta guhagarika serivisi y'amakuru; OTDR yo kuri interineti ishingiye kuri 1625 nm ibasha kubona mu buryo bwihuse ubusaza bw'insinga, aho zihagarara n'igihombo kidasanzwe, biba ikoranabuhanga ry'ingenzi ku miyoboro y'ubuhanga ya O&M y'insinga z'umugongo. EDFA ya L-band ihuye ishyigikira kwaguka kwa DWDM iyo umutungo wa C-band spectrum urangiye.
