Monga chipangizo chosinthira chithunzi chamagetsi, gawo la optical ndi chinthu chofala kwambiri pa intaneti yolumikizirana. Pakati pa mawonekedwe a ma modules optical, mphamvu yotumizira ndi imodzi mwazinthu zofunika kwambiri komanso zokhudzidwa kwambiri. Kuonjezera apo, mtunda wotumizira wa module optical ndi chinthu china chachikulu chomwe sichikhoza kunyalanyazidwa. M'magawo osiyanasiyana ndi maulalo a transmission optical communication network, mawonekedwe a optical modules amasiyananso.
Malingana ndi mtunda wotumizira wa optical module, ukhoza kugawidwa m'magulu atatu: short-distance optical module, medium-distance optical module, ndi mtunda wautali optical module. Njira yotalikirapo yotalikirapo imatanthawuza gawo la optical lomwe lili ndi mtunda wopitilira 30 km kapena kupitilira apo. Kufunika kotumiza mtunda wautali wa data ya netiweki.
Pakugwiritsa ntchito kwenikweni kwa mtunda wautali wa optical module, mtunda wothamanga kwambiri wa module sungapezeke nthawi zambiri. Izi ndichifukwa choti kufalikira kwamtundu wina kumachitika panthawi yopatsira chizindikiro cha optical mu fiber fiber. Kuti athetse vutoli, mtunda wautali wa Optical module umatengedwa. Utali umodzi wokha waukulu ndi laser yanga ya DFB monga gwero la kuwala, motero ndikupewa vuto la kubalalikana.
Ma module aatali amtundu wa optical akupezeka mu SFP optical modules, SFP + optical modules, XFP optical modules, 25G optical modules, 40G optical modules, ndi 100G optical modules. Pakati pawo, mtunda wautali wa SFP + optical module umatenga gawo la laser la EML ndi chigawo cha photodetector, chomwe chimachepetsa kugwiritsa ntchito mphamvu ya optical module ndikuwongolera kulondola; mtunda wautali wa 40G optical module umatenga dalaivala ndi unit modulation mu transmitting link, ndipo amalandira Ulalowu umagwiritsa ntchito amplifier optical ndi photoelectric conversion unit kuti akwaniritse mtunda wopita kumtunda wa 80 km.
Komabe, mtunda wotumizira wa module optical suli momwe mungathere, ndipo yankho loyenera liyenera kutengedwa ngati kuli koyenera. Mapulogalamu akutali ali makamaka m'magawo a ma seva,kusinthamadoko, madoko a makhadi a netiweki, kuyang'anira chitetezo, kulumikizana ndi matelefoni, Ethernet, ndi ma synchronous Optical network.
