一,Va'aiga fa'atekinisi o modules fa'apitoa
Optical module, e lauiloa foi o le optical transceiver integrated module, o le vaega autu lea i le faiga o fesoʻotaʻiga fiber optical. Latou te iloa le liua i le va o faʻailoga mataʻutia ma faʻailoga eletise, faʻatagaina faʻamatalaga e tuʻuina atu i le saoasaoa maualuga ma mamao mamao e ala i fesoʻotaʻiga fiber optical. Optical modules e aofia ai masini optoelectronic, circuits, ma casings, ma ei ai uiga o le saoasaoa maualuga, maualalo le faʻaaogaina o le eletise, ma le maualuga o le faʻatuatuaina. I fesoʻotaʻiga fesoʻotaʻiga faʻaonaponei, ua avea masini faʻapipiʻi ma mea autu e ausia ai le televave o faʻasalalauga faʻamatalaga ma faʻaaogaina lautele i nofoaga autu o faʻamatalaga, faʻasologa o ao, fesoʻotaʻiga eria, fesoʻotaʻiga i tua ma isi faʻalapotopotoga. O le ta'iala galue o le masini fa'apipi'i o le fa'aliliuina lea o fa'ailo eletise i fa'ailo fa'apitoa, fa'asalalau atu e ala i filo fa'apitoa, ma fa'aliliu fa'ailoga opitika i fa'ailoga eletise i le pito e maua ai. Aemaise lava, o le faʻaiʻuga e faʻaliliuina le faʻailoga faʻamatalaga i se faʻailoga mataʻutia ma tuʻuina atu i le pito e maua mai e ala i le fiber opitika, ma le faʻaiʻuga e toe faʻafoʻi ai le faʻailoga opitika i se faʻamatalaga faʻamatalaga. I lenei faiga, e iloa ai e le module opitika fa'asalalauga tutusa ma fa'asalalauga mamao o fa'amaumauga.
1.25Gbps 1310/1550nm 20km LC BIDIDDMSFP Module
二,Ituaiga o modules opitika
1.Fa'avasegaga ile saoasaoa:
E tusa ai ma le saoasaoa, e iai le 155M/622M/1.25G/2.125G/4.25G/8G/10G. 155M ma le 1.25G e masani ona faʻaaogaina i le maketi. O le tekonolosi o le 10G o loʻo faasolosolo malie ona matua, ma o loʻo faʻatupulaia le manaʻoga i se tulaga maualuga.
2.Fa'avasegaga ile umi ole galu:
E tusa ai ma le umi galu, ua vaevaeina i 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. Ole umi ole galu ole 850nm ole SFP multi-mode, ma ole mamao ole felauaiga e itiiti ifo ile 2KM. Ole umi ole galu ole 1310 / 1550nm e tasi le auala, ma o le mamao faʻasalalau e sili atu i le 2KM.
3.Fa'avasegaga ile faiga:
(1）Multimode: Toeitiiti lava o lapopoa uma multimode fiber o le 50 / 125um poʻo le 62.5 / 125um, ma o le bandwidth (le aofaʻi o faʻamatalaga e tuʻuina atu e le fiber) e masani lava 200MHz i le 2GHz. Telemode optical transceivers e mafai ona fa'asalalau atu ile 5 kilomita e ala ile Multimode fiber optical.
(2）Tusa-faiga: O le tele o le fiber tasi-mode o le 9-10 / 125μm, ma e le faʻatapulaʻaina le bandwidth ma maualalo ifo nai lo le tele-mode fiber. E masani ona fa'aogaina fa'aliliu mata'itusi tasi-mode mo felauaiga mamao, o nisi taimi e o'o atu i le 150 i le 200 kilomita.
三、 Fa'ata'ita'iga fa'apitoa ma fa'ailoga fa'atinoga
Pe a filifilia ma faʻaogaina modules opitika, e tatau ona e mafaufau i mea faʻapitoa faʻapitoa ma faʻailoga faʻatinoga:
1. Fa'aofi gau: Fa'aofi gau e fa'atatau i le leiloa o fa'ailo fa'apitoa a'o fa'asalalauina ma e tatau ona la'ititi e mafai ai ina ia mautinoa le lelei o fa'ailoga.
2. Fa'afo'i gau: Fa'afo'i gau e fa'atatau i le fa'afoliga gau o fa'ailo fa'apitoa a'o fa'asalalauina. O le tele o tupe leiloa o le a afaina ai le lelei o faailo.
3. Polarization mode dispersion: Polarization mode dispersion e faasino i le taʻape e mafua mai i le saoasaoa o vaega eseese o faailoilo opitika i setete polarization eseese. E tatau ona laʻititi pe a mafai e faʻamautinoa le lelei o faʻailoga.
4. Fuafuaga faʻaumatia: O le fua faʻaumatia e faʻatatau i le eseesega o le mana i le va o le maualuga ma le maualalo o le faʻailoga mata. E tatau ona laʻititi pe a mafai e faʻamautinoa le lelei o faʻailoga.
5. Digital diagnostic monitoring (DDM): E mafai ona mataʻituina e le numera o le suʻesuʻega faʻamaonia le tulaga faigaluega ma faʻataʻitaʻiga faʻatinoga o le module i le taimi moni e faʻafaigofie ai le faʻafitauli ma le faʻatinoina o galuega.
四, puipuiga mo le filifilia ma le faʻaaogaina
Pe a filifilia ma faʻaogaina modules opitika, e tatau ona e gauai atu i mea nei:
1. Fa'amatalaga o le fibre Optical: Modules e fetaui ma le fiber opitika sa'o na fa'aaogaina e tatau ona filifilia ina ia mautinoa ai le sili atu o le fa'asalalauga.
2. Auala fa'apipi'i: E tatau ona filifilia le module e fetaui ma le fa'aoga tonu o le masini e fa'amautinoa ai le sa'o o le fa'amau ma le mautu o le felauaiga.
3. Fesoʻotaʻiga: Modules e fetaui ma le masini moni e tatau ona filifilia ina ia mautinoa le fetaui lelei ma le mautu.
4. Fa'alesiosiomaga: Ole a'afiaga ole si'osi'omaga e pei ole vevela ma le susū ile fa'aoga moni ole si'osi'omaga ile fa'atinoga ole module e tatau ona iloiloina.
5. Tausiga ma le tausiga: E tatau ona asiasia ma tausia le module i taimi uma ina ia mautinoa ai lona faʻagaioiga tumau tumau.
