Optical eye image debugging

Optical eye image debugging Target:
Extinction ratio
Tsvagiridzo uye danho rekusimudzira: pakati pe10-15 (huru iri nani pane diki), zvinoenderana nemamiriro chaiwo anogona kuve akakodzera kuvandudza reshiyo yekutsakatika, asi kwete yakaderera. Zvinoenderana nekunzwa.
Quiver
Tsvagiridzo uye nhanho yekusimudzira: inodzorwa mukati me20PS. Izvo zvishoma zviri nani, zviri nani kuita kukanganisa.
Kuyambuka
Tsvagiridzo uye nhanho yekusimudzira: 48% -55%. Icho chiyero chenguva yekuverenga ye0 uye 1 mazinga. Kubatanidza neiyo yekuwedzera frequency ndiyo inofananidzira yekuita kwekuyananisa kurasikirwa.
Optical simba
Tsvagiridzo uye nhanho yekusimudzira: Kudzora pakati -3dbm~-9dbm. Tora kukosha kwepakati kusvika pazvinobvira, uye iwe unofanirwa kuyera reshiyo yekutsakatika uchipesana nehukoshi uhu kuti uite sarudzo yakanaka. Icho chiyero chesimba rechiratidzo.
Optical eye image debugging - Nzira:
1. Overshoot
Mufananidzo weziso unoratidza kubuda kwepakati pepamusoro; Mushonga wacho ndewekuvandudza muganhu unokwira
2. Undershoot
Chiratidzo cheziso chinoratidza kunonoka kwepasi; Mhinduro yekuvandudza kumucheto kunowira
3. Cross points
Kukosha uku kunogona kuverengwa zvakananga kubva kumepu yeziso ruzivo. Inogona kuenzaniswa nekugadzirisa voltage yeLD +, iyo voltage yeLD-, iyo Imod yazvino, uye inosiyanisa mutsara impedance.
4. Kushatirwa
Kukosha uku kunogona kuverengwa zvakananga kubva kumepu yeziso ruzivo. Inogona kuenzaniswa nekugadzirisa voltage yeLD +, iyo voltage yeLD-, iyo Imod yazvino, uye inosiyanisa mutsara impedance.
