An optical module ine photoelectronic component, inoshanda dunhu, uye yekuona interface. A photoelectronic component ine yekutumira uye kugamuchira zvikamu.
Kuzvitaura zviri nyore, basa re optical module is photoelectric conversion. Mhedzisiro yekutumira inoshandura zviratidzo zvemagetsi kuita zviratidzo zvemaziso, uye kuguma kwekugamuchira kunoshandura zviratidzo zvemaziso mumagetsi emagetsi mushure mekutumira kuburikidza nemagetsi emagetsi.
Single mode inomiririrwa ne SM, inokodzera kuendesa kure kure, nepo multi-mode inomiririrwa neMM, inokodzera kupfupika kwekufamba. iri 1310nm uye 1550nm.
Single-mode optical modules inoshandiswa pakufambisa kure-kure, uye kureba kwekufambisa kunosvika 150 kusvika 200km. Multi-mode optical modules inoshandiswa pakufamba kwenguva pfupi, nekufamba kure kusvika ku5km. Single-mode optical modules inoshandiswa kureba kureba, nekufamba kure kunosvika 150 kusvika 200km. Multi-mode optical modules inoshandiswa pakufamba kwenguva pfupi, nekufambisa kure kusvika ku5km.
Chiedza chemulti-mode optical module ndeye light-emitting diode kana laser, nepo chiedza che single-mode optical module iLD kana LED ine nhete inotaridzika.
Multi-mode optical modules inonyanya kushandiswa kupfupi-kure kufambisa, senge SR. Kune akawanda node uye majoini mumhando iyi yetiweki. Naizvozvo, akawanda-modhi optical modules anogona kuderedza mutengo.
Single-mode optical modules inonyanya kushandiswa mumitsara ine mwero wakanyanya wekutapurirana, senge MAN (Metropoliitan area network)
Uye zvakare, michina yemhando dzakasiyana-siyana inogona kungoshanda zvinobudirira pa-multi-mode fibers, nepo-single-mode madivayiri anogona kushanda zvinobudirira pane ese ma-single-mode uye akawanda-mode fibers.
Imwe-mode optical module inoshandisa zvakapetwa kaviri zvikamu se-multi-mode optical module. Nokudaro, iyo yose mari ye-single-mode optical module yakakwira zvikuru kupfuura ye-multi-mode optical module.
A high-rate optical module haigoni kushandiswa seyakaderera-chiyero optical module. A high-rate optical module inogona kushandiswa seyakaderera-chiyero optical module. Kunyangwe mamwe ma module optical achienderana nemamwe ma module optical, mamwe haaenderane.
Iro laser inobudiswa ne-single-mode optical module inogona kupinda yose mu optical fiber, asi mufiber optical ine-multi-mode transmission, kupararira kwakakura, kupfupika kwekufamba kwepakati kwakanaka. inowedzera, simba remaziso rekuguma kwekugamuchira rinogona kunge rakaremerwa. Nokudaro, unorayirwa kushandisa single-mode optical fibers panzvimbo ye-multi-mode optical fibers ye single-mode optical modules.
Optical modules inofanira kushandiswa mune peer mode. Semuenzaniso, chiyero chekufambisa, kureba kwekufambisa, nzira yekufambisa, uye kushanda kwewavelength yemamodule optical pakutumira nekugamuchira migumo inofanira kufanana. Interface tsanangudzo ye optical modules ine madhigirii akasiyana-siyana ekufambisa anosiyana zvikuru, uye optical modules ane marefu ekufambisa marefu ane mitengo yakakwirira.Kubatana kunogona kuitika kuburikidza nekufananidza zvakakodzera optical attenuation maererano nemamiriro chaiwo emambure.
Kana iyo yekutumira simba remaziso ekupedzisira kwevezera rakakura kudarika muganhu wepamusoro wekugamuchira optical simba remunharaunda optical module, unoda kubatanidza optical attenuate chiratidzo che optical pane chinongedzo, uye wozobatanidza nzvimbo ye optical module. optical module Kwemapfupi maapplication, shandisa optical attenuation, kunyanya kune-self-loop application, kudzivirira kupisa iyo optical module.
