Itandukaniro riri hagati ya transceivers za fiber optic zo mu buryo bumwe n'izikoresha uburyo bwinshi Uburyo 3 bwo gutandukanya transceivers za fiber optic zo mu buryo bumwe n'izikoresha uburyo bwinshi

1. Itandukaniro riri hagati ya transceivers za fiber optique zo mu bwoko bumwe n'izo mu buryo bwinshi

Umurambararo w'ibanze wa fibre ya multimode ni 50 ~ 62.5μm, umurambararo w'inyuma wa fibre ni 125μm, n'umurambararo w'ibanze wa fibre ya single-mode ni 8.3μm, naho umurambararo w'inyuma wa fibre ya cladding ni 125μm. Uburebure bw'uburebure bw'imirasire ya optique ni 0.85 μm ku burebure bw'izuba bugufi, 1.31 μm na 1.55 μm ku burebure bw'izuba bunini. Ubusanzwe igihombo cya fibre kigabanuka bitewe n'uburebure bw'umurambararo, igihombo cya 0.85μm ni 2.5dB/km, igihombo cya 1.31μm ni 0.35dB/km, naho igihombo cya 1.55μm ni 0.20dB/km, ari na cyo gihombo gito cya fibre, umurambararo w'uburebure wa 1.65. Igihombo kiri hejuru ya μm gikunze kwiyongera. Bitewe n’ingaruka za OHˉ zo kwinjiza, hari uburebure bw’igihombo buri hagati ya 0.90 ~ 1.30μm na 1.34 ~ 1.52μm, kandi izi ntera zombi ntizikoreshwa neza. Kuva mu myaka ya 1980, insinga zo mu bwoko bumwe zakunze gukoreshwa, kandi uburebure bw’umurambararo bwa 1.31 μm ni bwo bwa mbere bwakoreshejwe.
Fibre ya Multimode

Fibre ya Multimode: Ikirahure cyo hagati ni kinini (50 cyangwa 62.5μm), gishobora kohereza urumuri mu buryo bwinshi. Ariko ikwirakwira ryacyo hagati y’imirongo ni rinini, rigabanya inshuro zo kohereza ibimenyetso bya digitale, kandi rizaba rikomeye cyane iyo intera yiyongereye. Urugero: fibre ya 600MB/KM ifite bandwidth ya 300MB gusa kuri 2KM. Kubwibyo, intera yo kohereza fibre ya multimode ni ngufi, muri rusange ni kilometero nke gusa.

fibre imwe
Fibre y'uburyo bumwe (Fibre y'uburyo bumwe): Ikirahure cyo hagati ni gito cyane (umurambararo w'ibanze muri rusange ni μm 9 cyangwa 10), kandi uburyo bumwe gusa bw'urumuri bushobora koherezwa. Kubwibyo, ikwirakwira ryayo hagati y'ikirere ni rito cyane, rikwiriye itumanaho rya kure, ariko hari n'ikwirakwira ry'ibikoresho n'ikwirakwira ry'amaza, bityo fibre y'uburyo bumwe ifite ibisabwa byinshi ku bugari bwa spectral n'ubudahangarwa bw'isoko ry'urumuri, ni ukuvuga ko ubugari bwa spectral bugomba kuba buto kandi buhamye. Bibe byiza. Nyuma, byagaragaye ko ku bunini bwa 1.31 μm, ikwirakwira ry'ibikoresho n'ikwirakwira ry'amaza rya fibre y'uburyo bumwe ari byiza na bibi, kandi ingano ni imwe rwose. Ibi bivuze ko ku bunini bwa 1.31 μm, ikwirakwira ryose rya fibre y'uburyo bumwe ni zeru. Ukurikije imiterere y'igihombo cya fibre, 1.31μm ni idirishya rito ry'igihombo cya fibre. Muri ubu buryo, agace k'uburebure bwa metero 1.31 kabaye idirishya ryiza ryo gukoreramo itumanaho rya fibre optique, kandi ni na ryo tsinda rikuru rikora muri sisitemu z'itumanaho rya fibre optique. Ibipimo by'ingenzi bya fibre isanzwe ya metero 1.31 bigenwa n'Ihuriro Mpuzamahanga ry'Itumanaho ITU-T mu nama ya G652, bityo iyi fibre yitwa fibre G652.

Ese ikoranabuhanga rya "single-mode" na "multi-mode" rikorwa icyarimwe? Ese ni ukuri ko "multi-mode" igezweho cyane na "multi-mode" ari yo igezweho cyane? Muri rusange, "multi-mode" ikoreshwa mu ntera ngufi, kandi "single-mode" ni yo ikoreshwa mu ntera za kure, kuko "transmission" na "multi-mode" byakira "multi-mode" Igikoresho gihendutse cyane ugereranyije na "single-mode".

Fibre y'uburyo bumwe ikoreshwa mu kohereza amakuru kure, naho fibre y'uburyo bwinshi ikoreshwa mu kohereza amakuru imbere. Ni yo yonyine ikoreshwa mu kohereza amakuru kure, ariko si ngombwa ko ikoreshwa mu kohereza amakuru imbere.

Niba imigozi y'urumuri ikoreshwa muri seriveri n'ibikoresho byo kubika ari iy'uburyo bumwe cyangwa iy'uburyo bwinshi. Inyinshi muri zo zikoresha uburyo bwinshi, kuko nkora gusa ku migozi y'urumuri kandi ntabwo nzi neza iki kibazo.

Ese imigozi y'urumuri igomba gukoreshwa mu buryo bwa kabiri, kandi hari ibikoresho nka "single-hole single-mode fiber signal converters"?

Ese fibre optique igomba gukoreshwa mu buryo bwa kabiri? Yego, mu gice cya kabiri cy'ikibazo, urashaka kohereza no kwakira urumuri kuri fibre optique imwe? Ibi birashoboka. Umuyoboro wa fibre optique wa China Telecom wa 1600G umeze utya.

Itandukaniro ry'ingenzi hagati ya transceivers za fiber optique zo mu buryo bumwe na transceivers za fiber optique zo mu buryo bwinshi ni intera yo kohereza ubutumwa. Transceiver ya fiber optique yo mu buryo bwinshi ni transceiver y'ibimenyetso ifite node nyinshi na port nyinshi mu buryo bw'akazi, bityo transceiver y'ibimenyetso ni ngufi, ariko biroroshye cyane, kandi ntabwo ari ngombwa gukoresha imiterere ya intranet yo mu gace. Fibre imwe ni transceiver y'inode imwe, bityo ikaba ikwiriye kohereza imirongo miremire y'imirongo kandi ikaba ikora umushinga w'itumanaho ryambukiranya uturere tw'umujyi.

2. Uburyo bwo gutandukanya transceivers za fiber optique zo mu bwoko bumwe n'izo mu buryo bwinshi

Hari igihe tuba tugomba kwemeza ubwoko bwa transceiver ya fiber optique, none se twamenya dute niba transceiver ya fiber optique ari imwe cyangwa nyinshi?

?

1. Gutandukanya umutwe w'umusatsi, gukuraho umupfundikizo w'umusatsi wa fiber optic transceiver, hanyuma urebe ibara ry'ibice by'umusatsi biri mu mutwe w'umusatsi. Uruhande rw'imbere rw'umusatsi wa single-mode TX na RX rutwikiriwe n'ibumba ryera, kandi umusatsi wa multi-mode ni umukara.

2. Gutandukanya na moderi: muri rusange reba niba hari S na M muri moderi, S bivuga uburyo bumwe, M bivuga uburyo bwinshi.

3. Niba yashyizweho kandi ikoreshwa, ushobora kubona ibara rya fibre jumper, orange ifite uburyo bwinshi, umuhondo ni uburyo bumwe
