FCmea hoʻokuʻu fiber optiche mea hoʻohana ʻia e hoʻemi i ka amplitude o kahi hōʻailona māmā me ka hoʻololi ʻole ʻana i ke ʻano nalu ponoʻī.He koi pinepine kēia i nā noi Dense Wave Division Multiplexing (DWDM) a me Erbium Doped Fiber Amplifier (EDFA) kahi i hiki ʻole ai i ka mea hoʻokipa ke ʻae i ka hōʻailona i hana ʻia mai kahi kumu kukui mana kiʻekiʻe.
FC attenuatore hōʻike ana i kahi ʻano proprietary o ka metala-ion doped fiber e hōʻemi ana i ka hōʻailona māmā i kona hele ʻana.ʻO kēia ʻano o ka attenuation e ʻae ai i ka hana ʻoi aku ka maikaʻi ma mua o ka fiber splices a i ʻole ka fiber offsets a i ʻole ka hoʻomaʻemaʻe fiber, e hana ana ma ke kuhi hewa ʻana ma mua o ka lawe ʻana i ka hōʻailona māmā.Hiki i nā attenuators FC ke hana i ka 1310 nm a me 1550 nm no Single-Mode a me 850nm no Multi-Mode.
FC attenuatorshiki iā lākou ke pale aku ma luna o 1W o ka ʻike kukui mana kiʻekiʻe no nā manawa lōʻihi, e kūpono ana iā EDFA a me nā noi mana kiʻekiʻe.Haʻahaʻa Polarization Dependent Loss (PDL) a me ka paʻa a kūʻokoʻa hawewe lōʻihi e hoʻolilo iā lākou kūpono no DWDM.
