Kuumbwa kwe optical communication devices

The composition ofoptical communication devices

Iyo yekutaurirana sisitimu ine mwenje wave sechiratidzo uye iyo Optical faibha senzira yekufambisa inonzi Optical fiber communications system. Zvakanakira zve optical fiber kutaurirana kana zvichienzaniswa neyechinyakare tambo yekukurukurirana uye isina waya kutaurirana ndeiyi: yakakura yekutaurirana kugona, yakaderera kutapurirana kurasikirwa, yakasimba anti-electromagnetic kupindira kugona, kuvanzika kwakasimba, uye mbishi ye optical fiber transmission medium isilicon dioxide ine yakawanda yekuchengetedza. Pamusoro pezvo, optical fiber ine zvakanakira saizi diki, huremu huremu uye mutengo wakaderera uchienzaniswa netambo.
Iyo inotevera dhizaini inoratidza zvikamu zveiyo nyore photonic yakabatanidzwa sedunhu:laser, kushandiswa zvakare kwemaziso uye demultiplexing mudziyo,photodetectoruyemodulator.

Iyo yakakosha chimiro che optical fiber bidirectional communication system inosanganisira: yemagetsi transmitter, optical transmitter, transmitter fiber, optical receiver uye yemagetsi inogamuchira.
Chiratidzo chemagetsi chepamusoro-soro chakavharidzirwa nemagetsi emagetsi kune transmitter ye optical, inoshandurwa kuita zviratidzo zvemagetsi ne electro-optical madivayiri akadai seLaser device (LD), yozobatanidzwa kune yekufambisa fiber.
Mushure mekufambisa kureba kwechiratidzo chemaziso kuburikidza ne-single-mode fiber, erbium-doped fiber amplifier inogona kushandiswa kukwidziridza chiratidzo chemaziso uye kuenderera mberi nekutapurirana. Mushure mekuguma kwekugamuchira maziso, chiratidzo chemaziso chinoshandurwa kuva chiratidzo chemagetsi nePD uye mamwe madivayiri, uye chiratidzo chinogamuchirwa nemagetsi anogamuchira kuburikidza nekugadzirisa kwemagetsi kunotevera. Nzira yekutumira nekugamuchira zviratidzo kune imwe nzira yakafanana.
Kuti uwane iyo yakamisikidzwa yemidziyo mune chinongedzo, iyo optical transmitter uye yekuona inogamuchira munzvimbo imwechete inosanganiswa zvishoma nezvishoma muOptical Transceiver.
The high-speedOptical transceiver moduleinoumbwa neReceiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) inomiririrwa neanoshanda optical midziyo, passive devices, functional circuits uye photoelectric interface zvikamu zvakaiswa. optical chips.

Mukutarisana nekunetseka kwemuviri uye matambudziko ehunyanzvi akasangana nawo mukuvandudza tekinoroji yemicroelectronics, vanhu vakatanga kushandisa mafotoni sevatakuri veruzivo kuti vawane bandwidth yakakura, kumhanya kwepamusoro, kuderera kwesimba rekushandisa, uye kuderera kunonoka photonic inteated circuit (PIC). Chinangwa chakakosha chephotonic integrated loop ndechekuona kubatanidzwa kwemabasa echizvarwa chechiedza, kubatanidza, modulation, kusefa, kutapurirana, kuona uye zvichingodaro. Simba rekutanga rekutyaira rephotonic integrated circuits rinobva pakukurukurirana kwedata, uyezve rakagadziridzwa zvakanyanya mumicrowave photonics, quantum information processing, nonlinear optics, sensors, lidar nemamwe minda.
