    Matanho mana akakosha ekuyedza optical modules

    Nguva yekutumira: Aug-14-2019

    Mushure mokunge optical module yakaiswa, kuedza kushanda kwayo inhanho inokosha.Kana zvikamu zvemaziso muhutano hwese network zvinopiwa nemutengesi mumwe chete, kana network network inogona kushanda zvakanaka, hapana chikonzero chekuedza zvakasiyana-siyana zvikamu zviduku. of the system.Zvisinei, mazhinji ezvidiki-zvikamu mune akawanda network masisitimu anobva kune vakasiyana vatengesi. Naizvozvo, kuyedza zvinhu zvemaziso, kunyanya mashandiro uye kudyidzana kweimwe neimwe optical module kwakakosha. Saka iwe unoyedza sei mashandiro eiyo optical module?

    Iyo optical module inoumbwa neanotumira uye anogamuchira.Apo iyo transmitter yakabatana kune anogamuchira kuburikidza neoptical fiber, kana iyo yekukanganisa mwero weiyo system yese isingaite zvinotarisirwa, idambudziko rekutumira kana dambudziko rekugamuchira? Iyo test optical module inowanzo patsanurwa kuita matanho mana, ayo anonyanya kukamurwa kuita bvunzo dzeanotumira uye anogamuchira.

    Transmitter test

    Paunenge uchiyedza, iwe unofanirwa kutarisisa kune wavelength uye chimiro cheiyo transmitter inobuda waveform, pamwe neiyo jitter kushivirira uye bandwidth yeanogamuchira. Paunenge uchiyedza transmitter, unofanirwa kutarisisa kune anotevera mapoinzi maviri: Chekutanga: Hunhu hwechiratidzo chekuisa chinoshandiswa kuyedza transmitter hunofanirwa kunge hwakakwana. Pamusoro pezvo, mhando yezviyero zvemagetsi zvinofanirwa kusimbiswa nezviyero zvejitter uye. kuyerwa kwedhiyagiramu yeziso.Kuyera dhayagiramu yeziso inzira yakajairika yekutarisa kubuda kwewaveform yeanotumira nekuti dhayagiramu yeziso ine hupfumi hweruzivo runoratidza kushanda kwese kweiyo transmitter.

    Chechipiri: Iyo inoburitsa chiratidzo cheiyo transmitter inofanirwa kuyerwa nemhando yemhando zviratidzo seyeye dhiyagiramu yeziso, optical modulation amplitude uye kupera kwechiyero.

    Receiver test

    Paunenge uchiyedza anogamuchira, iwe zvakare unofanirwa kuterera kune anotevera mapoinzi maviri:

    Chekutanga:Kusiyana nemuyedzo wekutepfenyura, mhando yechiratidzo chemaziso inofanirwa kuve yakashata zvakakwana kana uchiyedza anogamuchira. Naizvozvo, dhiyabhorosi yeziso rakareruka rinomiririra chiratidzo chakaipisisa chinofanira kugadzirwa. Iyi yakaipisisa chiratidzo chemaziso chinofanira kupfuura jitter. Kuyera uye optical simba bvunzo dzinoshandiswa pakuenzanisa.

    Chechipiri: Chekupedzisira, iwe unofanirwa kuyedza iyo inogamuchira yemagetsi inobuda chiratidzo. Kune marudzi matatu makuru ebvunzo:

    Muedzo wedhiyagiramu yeziso: Izvi zvinovimbisa kuti "meso" eiyo dhizaini yeziso akavhurika. Kuongororwa kwedhiyagiramu yeziso kunowanzo kuwanikwa nekudzika kweiyo bit kukanganisa mwero

    Jitter bvunzo: edza marudzi akasiyana ejitter

    Jitter yekutevera uye kushivirira: Edza kuteedzera kwejitter neyemukati wachi yekudzoreredza wedunhu

    Iyo light test module ibasa rakaoma, asi zvakare inhanho yakakosha kuti ive nechokwadi chekuita kwayo. Senzira yekuyera yakashandiswa zvakanyanya, kuyerwa kwedhiyagiramu yeziso kunogona kunyatso kuyedza emitter yeiyo optical module. Iyo yekugamuchira bvunzo yeOptical module yakanyanya kuomarara uye inoda dzimwe nzira dzekuyedza.
