Zolandirira za fiber opticndi ma module optical receiver ndi zida zofunika kwambiri pakulankhulana kwa kuwala, koma zimasiyana mu ntchito, zochitika zogwiritsidwa ntchito, ndi makhalidwe.
1. Chosinthira kuwala kwa fiber:
Chosinthira ma fiber optic ndi chipangizo chomwe chimasintha ma signal optic kukhala ma signal amagetsi (kumapeto kotumizira) kapena kusintha ma signal amagetsi kukhala ma signal optical (kumapeto kolandira). Ma fiber optic transceivers amaphatikiza zinthu monga ma laser transmitter modules, ma photoelectric converters, ndi ma circuit driver. Nthawi zambiri amaikidwa m'malo olumikizira ma optical module a zida za netiweki (monga ma switch, ma routers, ma servers, ndi zina zotero) mu phukusi lokhazikika. Ma fiber optic transceivers amagwiritsidwa ntchito popereka kusintha kwa ma signal pakati pa kuwala ndi magetsi, ndipo amagwira ntchito yotumiza ma signal panthawi yotumizira deta.
2. Chotumizira ma module optical:
Chosinthira ma module optical ndi chipangizo chosinthira ma module chomwe chimaphatikiza chosinthira ma fiber optic. Chosinthira ma module optical nthawi zambiri chimakhala ndi mawonekedwe a fiber optical, module yotumiza ma signal optical (transmitter), ndi module yolandira ma signal optical (receiver). Chosinthira ma module optical chili ndi kukula kofanana ndi mawonekedwe ake ndipo chimatha kuyikidwa mu malo a optical module mu zida za netiweki monga ma switch ndi ma router. Chosinthira ma module optical nthawi zambiri chimaperekedwa ngati module yodziyimira payokha kuti chikhale chosavuta kusintha, kukonza, komanso kukweza.
Ubwino wa transceiver ya fiber optic ndi module ya optic
1. Chosinthira kuwala kwa fiber
Kuyika ntchito
Amagwiritsidwa ntchito posintha chizindikiro cha photoelectric (monga Ethernet electrical port kukhala optical port), kuthetsa vuto la kulumikizana kwa media zosiyanasiyana (copper cable ↔ optical fiber).
Kawirikawiri chipangizo chodziyimira pawokha, chimafuna magetsi akunja, ndipo chimapereka madoko owunikira 1 ~ 2 ndi madoko amagetsi (monga RJ45).
Chitsanzo cha ntchito
Wonjezerani mtunda wotumizira: sinthani chingwe cha mkuwa choyera, phwanyani malire a mamita 100 (ulusi wa kuwala wa single-mode ukhoza kufika pamtunda woposa 20km).
Kukula kwa netiweki: kulumikiza magawo a netiweki azinthu zosiyanasiyana (monga netiweki ya kusukulu, njira yowunikira).
Malo a mafakitale: amasintha malinga ndi kutentha kwambiri komanso zochitika zamphamvu zosokoneza ma elekitiromagineti (mitundu ya mafakitale).
Ubwino
Pulagi ndi kusewera: palibe makonzedwe ofunikira, oyenera ma netiweki ang'onoang'ono kapena mwayi wolowera m'mphepete.
Mtengo wotsika: woyenera kuthamanga pang'ono komanso mtunda waufupi (monga 100M/1G, fiber yamagetsi yamitundu yambiri).
Kusinthasintha: kumathandiza mitundu yosiyanasiyana ya ulusi (mode imodzi/mode yambiri) ndi ma wavelengths (850nm/1310nm/1550nm).
Zoletsa
Kugwira ntchito kochepa: Nthawi zambiri sikuthandizira kuthamanga kwambiri (monga kupitirira 100G) kapena ma protocol ovuta.
Kukula kwakukulu: Zipangizo zodziyimira pawokha zimatenga malo.
2. Module Yowunikira
Malo Ogwirira Ntchito
Ma interfaces a kuwala (monga SFP ndi QSFP slots) ophatikizidwa mu ma switch, ma rauta ndi zida zina amamaliza mwachindunji kusintha kwa ma signali a kuwala ndi magetsi.
Thandizani ma protocol othamanga kwambiri komanso ambiri (monga Ethernet, Fibre Channel, CPRI).
Zochitika zogwiritsira ntchito
Deta: kulumikizana kwamphamvu kwambiri, kuthamanga kwambiri (monga ma module a 40G/100G/400G optical).
Netiweki yonyamula 5G: zofunikira pa liwiro lapamwamba komanso latency yotsika ya fronthaul ndi midhaul (monga ma module a 25G/50G imvi).
Netiweki yayikulu: kutumiza kwakutali (monga ma module a DWDM okhala ndi zida za OTN).
Ubwino
Kuchita bwino kwambiri: kumathandizira mitengo kuyambira 1G mpaka 800G, kukwaniritsa miyezo yovuta monga SDH ndi OTN.
Zosinthika: zosinthika mosavuta (monga ma module a SFP+) kuti zisinthe mosavuta komanso kukonza.
Kapangidwe kakang'ono: kolumikizidwa mwachindunji mu chipangizocho kuti musunge malo.
Zoletsa
Zimadalira chipangizo cholandirira: chiyenera kugwirizana ndi mawonekedwe ndi protocol ya switch/rauta.
Mtengo wokwera: Ma module othamanga kwambiri (monga ma module opangidwa ndi coherent optical) ndi okwera mtengo.
Pomaliza
Ma transceiver a fiber opticndi zipangizo zomwe zimasintha zizindikiro zamagetsi kukhala zizindikiro zamagetsi kapena zizindikiro zamagetsi kukhala zizindikiro zamagetsi, ndipo nthawi zambiri zimayikidwa m'malo olumikizira ma module amagetsi;
Ma transceivers a module ya kuwala ndi zida zolumikizira ma transceivers a fiber optic, nthawi zambiri zimakhala ndi ma fiber optic interfaces, ma transmitters, ndi ma receivers. Kapangidwe ka modular kodziyimira pawokha. Ma transceivers a module ya kuwala ndi njira yogwiritsira ntchito ma transceivers a fiber optic omwe amagwiritsidwa ntchito pothandizira kuphatikiza ndi kuyang'anira zida zolumikizirana ndi kuwala.
