Sechigadziriso chephotoelectric, iyo optical module ndiyo inonyanya kuwanikwa chigadzirwa mune optical communication network.Pakati pemaitiro e optical modules, simba rekutapurirana ndeimwe yeakanyanya kukosha uye ane hanya ma paramita.Uye zvakare, kureba kwekufambisa kweiyo optical module ndiyo imwe core parameter isingagoni kuregererwa.Muminda yakasiyana uye zvinongedzo zve optical communication network transmission, hunhu hwe optical modules hwakasiyanawo.
Zvinoenderana nedanho rekufambisa reiyo optical module, inogona kukamurwa kuita mhando nhatu: pfupi-kure optical module, yepakati-kure optical module, uye kure-kure-kure optical module.Iyo yakareba-refu optical module inoreva optical module ine nhambwe yekufambisa yemakiromita makumi matatu kana kupfuura.Iko kudiwa kwekureba-kure kuendesa data network.
Mukushandiswa chaiko kweiyo kureba-kure optical module, iyo yakakura yekufambisa kureba kweiyo module haigone kuwanikwa muzviitiko zvakawanda.Izvi zvinodaro nekuti imwe dhigirii yekupararira inoitika panguva yekufambiswa kweiyo optical chiratidzo mune optical fiber.Kugadzirisa dambudziko iri, iyo yakareba-kure optical module inogamuchirwa.Imwe chete inotonga wavelength ndiyo yangu DFB laser semwenje sosi, nekudaro kudzivirira dambudziko rekupararira.
Marefu-range optical modules anowanikwa muSFP optical modules, SFP + optical modules, XFP optical modules, 25G optical modules, 40G optical modules, uye 100G optical modules.Pakati pavo, iyo yakareba SFP + optical module inotora EML laser component uye photodetector chikamu, iyo inoderedza kushandiswa kwesimba re optical module uye inovandudza kururama;iyo yakareba-kure 40G optical module inotora mutyairi uye modulation unit mumutambo wekutumira, uye inogamuchira Iyo link inoshandisa an optical amplifier uye photoelectric conversion unit kuti iwane nzvimbo yakakura yekuendesa kure kwe80 km.
Nekudaro, kureba kwekufambisa kweiyo optical module haisi kure sezvinobvira, uye mhinduro yakakodzera inofanira kutorwa pazvinenge zvakakodzera.Iwo marefu maapplication ari kunyanya muminda yeserver ports, switch ports, network kadhi ports, chengetedzo yekutarisa, telecommunications, Ethernet, uye synchronous optical network.
