Mumakore achangopfuura, mhando itsva yefiber ye optical, G.654E, yave ichishandiswa mune dzimwe nzira dzemusana dzinoshanda kure uye dzakawana mhedzisiro yakanaka. Saka, chii chinonzi fiber ye optical yeG.654E? Fiber yeG.654E ichatsiva fiber yeG.652D yechinyakare here?
Pakati pemakore ekuma1980, kuti zvienderane nezvinodiwa zvekutaurirana kure kwetambo dzemugungwa dzefiber optic, fiber ye single-mode optical ine pure silica core uye wavelength ye1550 nm yakagadzirwa. Kudzikira kwayo pedyo newavelength iyi kwakaderera ne10% pane kwe Fiber optics G.652 pamusoro apa.
Rudzi urwu rwefayibha runotsanangurwa sefayibha yeG.654, uye zita rayo panguva iyoyo raive "fayibha yemhando imwe chete ine urefu hwemafungu e1550 nm".
Mumakore ekuma1990, tekinoroji yeWDM yakatanga kushandiswa mumasisitimu ekutaurirana kwemaziso pasi pemvura. Tekinoroji yeWDM inobvumira kutapurirana panguva imwe chete kwemachiteshi akawanda kana kunyange mazana emagetsi pamusoro pefiber imwe chete, uye nekushandisa maamplifiers efiber optic, masaini emagetsi ane simba guru, akawanda-wavelength anobatanidzwa kuita fiber imwe chete uye anosanganiswa pane imwe interface diki. Masaini aya anoratidza hunhu husina kurongeka.
Nekuda kwekusashanda kwe fiber ye optical, kana simba re optical richipinda mu fiber rikadarika kukosha kwakati, mashandiro e transmission ye system anodzikira zvishoma nezvishoma nekuwedzera kwe simba re optical richipinda mu fiber.
Mhedzisiro isiri yemutsara we fiber ye optical ine chekuita nehukuru hwesimba re optical re fiber core. Kana simba re optical rinopinda rikaramba riripo, kuwedzera nzvimbo inoshanda ye cross-sectional ye fiber ye optical uye kuderedza hurefu hwesimba re optical re fiber core kunogona kuderedza simba re nonlinear effect pakushanda kwe transmission. Saka, G.654 optical fiber yakatanga kukonzera gakava nekuda kwekuwedzera kwayo kushanda kwe cross-sectional area.
Kuwedzera nzvimbo inoshanda yefiber kuchaita kuti pave nekuwedzera kwe cutoff wavelength, asi kuwedzera kwe cutoff wavelength kunofanira kudzorwa kuitira kuti kusakanganisa kushandiswa kwefiber muC band (1530nm ~ 1565nm), saka, cutoff wavelength ye fiber yeG.654 yakaiswa pa1530nm.
Muna 2000, apo ITU yakagadzirisa G.654 optical fiber standard, yakachinja zita iri kuita "cut wavelength-shifted single-mode optical fiber".
Kusvika pari zvino, fiber yeG.654 yagara ichizivikanwa nekuderera kwesimba remagetsi uye nzvimbo yakakura inoshanda. Zvadaro, fiber yeG.654 inoshandiswa pakutaurirana netambo dzemugungwa yakagadziriswa zvakanyanya kuti iwedzere simba remagetsi uye nzvimbo inoshanda, uye zvishoma nezvishoma yakazokura kuita zvikamu zvina: A, B, C, naD.
