1.Laser waeʻano
ʻO ka laser ka mea nui loa o kahi module optical e hoʻokomo i kēia manawa i loko o kahi mea semiconductor a hoʻokuʻu i ke kukui laser ma o nā oscillations photon a me nā loaʻa i loko o ka lua.I kēia manawa, ʻo nā lasers i hoʻohana pinepine ʻia ʻo FP a me DFB lasers.ʻO ka ʻokoʻa, ʻokoʻa ka mea semiconductor a me ke ʻano o ka lua.ʻOi aku ke kumukūʻai o ka laser DFB ma mua o ka laser FP.Hoʻohana maʻamau nā modula Optical me nā mamao hoʻouna a hiki i 40KM i nā lasers FP;hoʻohana maʻamau nā modula optical me nā mamao hoʻouna ≥40KM i nā lasers DFB.
2.Loss a me ka hoopuehu
ʻO ka poho ka nalowale o ka ikehu māmā ma muli o ka absorption a me ka hoʻopuehu ʻana o ka mea waena a me ka leakage o ka mālamalama i ka wā e hoʻouna ʻia ai ke kukui i loko o ka fiber.Hoʻopau ʻia kēia ʻāpana o ka ikehu ma kekahi ʻano e like me ka piʻi ʻana o ka mamao o ka hoʻouna ʻana. ʻO ka hoʻopuehu ʻia ma muli o ka like ʻole o ka wikiwiki o nā hawewe electromagnetic o nā lōʻihi hawewe like ʻole e hoʻolaha ana i loko o ke ʻano like ʻole, ka mea e hoʻopiʻi ai i nā ʻāpana hawewe like ʻole o ka hōʻailona optical a hiki i ka ka loaʻa ʻana o ka hopena i nā manawa like ʻole ma muli o ka hōʻiliʻili ʻana o ka mamao o ka hoʻouna ʻana, ka hopena o ka hoʻonui ʻana i ka pulse a no laila hiki ʻole ke ʻike i ka waiwai o nā hōʻailona.Ma ke kaʻina hana noi maoli, ʻo ka 1310nm optical module e helu maʻamau i ka nalowale o ka loulou ma 0.35dBm/km, a me ka 1550nm optical module e helu maʻamau i ka nalowale o ka loulou ma .20dBm/km, a helu i ka waiwai dispersion.Paʻakikī loa, maʻamau no ka ʻike.
3.Transmitted ka mana optical a me ka loaʻa ʻana o ka naʻau
ʻO ka mana optical i hoʻouna ʻia e pili ana i ka mana optical output o ke kumu kukui ma ka hopena hoʻouna o ka module optical.ʻO ka naʻau o ka loaʻa ʻana e pili ana i ka liʻiliʻi loa i loaʻa i ka mana optical o ka module optical ma kahi helu a me ka hapa hapa hapa.ʻO nā ʻāpana o kēia mau ʻāpana ʻelua he dBm (ʻo ia hoʻi ka decibel milliwatt, ka logarithm o ka mana mana mw, ka helu helu ʻana he 10lg, 1mw ua hoʻololi ʻia i 0dBm), ka mea i hoʻohana nui ʻia e wehewehe i ka mamao o ka lawe ʻana o ka huahana, nā hawewe like ʻole, ʻOkoʻa ka mana hoʻouna a me ka loaʻa ʻana o ka naʻau o ka module optical, inā hiki ke hōʻoia ʻia ka mamao o ka lawe ʻana.
4.Optical module ola
Nā kūlana hoʻohui honua, 50,000 mau hola o ka hana mau, 50,000 mau hola (e like me 5 mau makahiki).
ʻO nā modula optical SFP he mau kikowaena LC āpau.ʻO nā modules optical GBIC he mau kikowaena SC āpau.ʻO nā mea hoʻopili ʻē aʻe me FC a me ST.
