一,Kuwunikira mwachidule kwa ma module optical
Optical module, yomwe imadziwikanso kuti optical transceiver Integrated module, ndiye chigawo chachikulu mu optical fiber communication system. Amazindikira kutembenuka pakati pa ma siginecha owoneka ndi ma siginecha amagetsi, kulola kuti deta itumizidwe pa liwiro lalikulu komanso mtunda wautali kudzera mu ma network optical fiber. Ma module a Optical amapangidwa ndi zida za optoelectronic, mabwalo, ndi ma casings, ndipo ali ndi mawonekedwe othamanga kwambiri, kugwiritsa ntchito mphamvu zochepa, komanso kudalirika kwambiri. M'magulu amakono oyankhulana, ma modules optical akhala chigawo chofunikira kwambiri kuti akwaniritse kutumizirana mauthenga othamanga kwambiri ndipo amagwiritsidwa ntchito kwambiri m'malo opangira deta, cloud computing, metropolitan area networks, backbone networks ndi zina. Mfundo yogwira ntchito ya optical module ndiyo kutembenuza zizindikiro zamagetsi kukhala zizindikiro za kuwala, kuzitumiza kudzera muzitsulo za optical, ndikusintha zizindikiro za kuwala kukhala zizindikiro zamagetsi pamapeto olandira. Mwachindunji, mapeto otumizira amasintha chizindikiro cha deta kukhala chizindikiro cha kuwala ndikuchipititsa kumalo olandirira kupyolera mu fiber optical, ndipo mapeto olandira ndiye amabwezeretsa chizindikiro cha kuwala ku chizindikiro cha deta. Mwanjira iyi, gawo la optical limazindikira kufalikira kofananira komanso kutumiza kwakutali kwa data.
1.25Gbps 1310/1550nm 20km LC BIDIDDMSFP Module
二,Mitundu ya ma module a kuwala
1.Gulu ndi liwiro:
Malinga ndi liwiro, pali 155M/622M/1.25G/2.125G/4.25G/8G/10G. 155M ndi 1.25G amagwiritsidwa ntchito kwambiri pamsika. Tekinoloje ya 10G ikukula pang'onopang'ono, ndipo kufunikira kukukulirakulira.
2.Kugawikana ndi kutalika kwa mafunde:
Malinga ndi kutalika kwa mafunde, imagawidwa kukhala 850nm/1310nm/1550nm/1490nm/ 1530nm/1610nm. Kutalika kwa 850nm ndi SFP multi-mode, ndipo mtunda wotumizira ndi wochepera 2KM. Kutalika kwa 1310 / 1550nm ndi njira imodzi, ndipo mtunda wotumizira ndi woposa 2KM.
3.Kugawa ndi mode:
(1）Multimode: Pafupifupi makulidwe onse a multimode fiber ndi 50/125um kapena 62.5/125um, ndipo bandwidth (kuchuluka kwa chidziwitso chofalitsidwa ndi fiber) nthawi zambiri ndi 200MHz mpaka 2GHz. Multimode optical transceivers amatha kutumiza mpaka 5 kilomita kudzera mu Multimode optical fibers.
(2）Njira imodzi: Kukula kwa fiber single-mode ndi 9-10 / 125μm, ndipo ili ndi bandwidth yopanda malire komanso kutayika kochepa kuposa ulusi wamitundu yambiri. Ma transceivers opanga mawonekedwe amodzi amagwiritsidwa ntchito kwambiri pakutumizira anthu mtunda wautali, nthawi zina mpaka 150 mpaka 200 kilomita.
三、 Magawo aumisiri ndi zizindikiro zogwirira ntchito
Mukasankha ndikugwiritsa ntchito ma module a Optical, muyenera kuganizira zotsatirazi zaukadaulo ndi zizindikiro zogwirira ntchito:
1. Kutayika kolowetsa: Kutayika kumatanthauza kutayika kwa zizindikiro za kuwala panthawi yopatsirana ndipo ziyenera kukhala zazing'ono momwe zingathere kuti zitsimikizire mtundu wa chizindikiro.
2. Kubwereranso kutayika: Kubwerera kutayika kumatanthauza kutayika kwa chiwonetsero cha ma siginecha owoneka panthawi yopatsira. Kutayika kwakukulu kobwerera kudzakhudza khalidwe la chizindikiro.
3. Kubalalika kwa Polarization mode: Kubalalika kwa polarization kumatanthawuza kubalalitsidwa komwe kumachitika chifukwa cha ma liwiro osiyanasiyana amagulu a ma siginecha owoneka m'maiko osiyanasiyana. Iyenera kukhala yaying'ono momwe ingathere kuti zitsimikizire mtundu wa chizindikiro.
4. Chiŵerengero cha kutha: Chiŵerengero cha kutha chimatanthawuza kusiyana kwa mphamvu pakati pa mlingo wapamwamba ndi mlingo wochepa wa chizindikiro cha kuwala. Ziyenera kukhala zazing'ono momwe zingathere kuti zitsimikizire mtundu wa chizindikiro.
5. Digital diagnostic monitoring (DDM): Ntchito yowunikira matenda a digito ikhoza kuyang'anira momwe ntchito ikugwirira ntchito ndi magawo a ntchito ya module mu nthawi yeniyeni kuti athandize kuthetsa mavuto ndi kukhathamiritsa ntchito.
四、Kusamala posankha ndi kugwiritsa ntchito
Mukasankha ndikugwiritsa ntchito ma module optical, muyenera kulabadira izi:
1. Mawonekedwe a fiber fiber: Ma module omwe amafanana ndi fiber yeniyeni yomwe imagwiritsidwa ntchito ayenera kusankhidwa kuti atsimikizire kuti njira yabwino yopatsirana.
2. Docking njira: Gawoli liyenera kusankhidwa kuti lifanane ndi mawonekedwe enieni a chipangizo kuti zitsimikizidwe kuti docking yoyenera ndi kufalitsa kokhazikika.
3. Kugwirizana: Ma modules omwe amagwirizana ndi chipangizo chenichenicho ayenera kusankhidwa kuti atsimikizire kugwirizana bwino ndi kukhazikika.
4. Zinthu zachilengedwe: Zotsatira za zinthu zachilengedwe monga kutentha ndi chinyezi m'malo enieni omwe amagwiritsidwa ntchito pa ntchito ya module ziyenera kuganiziridwa.
5. Kusamalira ndi kukonza: Gawoli liyenera kuyang'aniridwa ndi kusungidwa nthawi zonse kuti liwonetsetse kuti likugwira ntchito mokhazikika kwa nthawi yayitali.
