Zita rakazara reoptical module ndereoptical transceiver, iyo yakakosha mudziyo mu optical fiber communication system.Iyo ine basa rekushandura iyo yakagamuchirwa optical chiratidzo muchiratidzo chemagetsi, kana kushandura chiratidzo chemagetsi chekupinza muchiratidzo chakagadzikana chemaziso pamwero unoenderana.
TheOptical module inoumbwa ne optoelectronic madivayiri, anoshanda maseketi uye optical interfaces.Iyo optoelectronic zvishandiso zvinosanganisira zvikamu zviviri: kutumira (TOSA) uye kugamuchira (ROSA).
Iwo akakosha tekinoroji maparamendi eiyo optical module anosanganisira avhareji inofambiswa optical simba, kupera kwechiyero, kugamuchira senitivity, uye saturated optical simba.
1. Avhareji inofambiswa simba rekuona inoreva masvomhu zvinoreva simba rekuona kana chiratidzo chechiratidzo chiri 1 uye simba rekuona kana iri 0.
2. The extinction ratio inoreva chiyero cheavhareji inofambiswa optical power yeese "1" macode kune avhareji inofambiswa optical simba reese "0" macode.Ichakanganisa kugamuchira kunzwa.Kutsakatika kwereshiyo kunofanirwa kudzorwa mukati mechikamu chinonzwisisika.Chiyero chakakura chekutsakatika chinobatsira kudzikisa chirango cheSimba, asi chakakurisa chinozowedzera jitter ine chekuita nelaser.
3. Kugamuchira senitivity kunoreva muganhu wediki iyo iyo yekugamuchira yekupedzisira inogona kugamuchira chiratidzo.Apo simba rechiratidzo chekuguma kwekugamuchira iri shoma pane yakajairwa kugamuchira senitivity, iyo yekupedzisira yekugamuchira haigamuchire chero data.
4. Iyo yakazara optical simba kukosha inoreva iyo yakanyanya detectable optical simba pamugumo wekugamuchira we optical module, kazhinji -3dBm.Kana iyo yakagamuchirwa optical simba yakakura kupfuura saturated optical simba, bit zvikanganiso zvinogadzirwa zvakare.Naizvozvo, kana iyo optical module ine yakakwirira transmitting optical simba yakaedzwa pasina attenuation uye loopback, zvikanganiso zvishoma zvichaitika.
