Ndeipi fiber optical inoshandiswa kutapurirana network kuvaka?
Kune marudzi matatu makuru: G.652 yakajairika-mode fiber, G.653 dispersion-shifted single-mode fiber and G.655 isiri-zero dispersion-shifted fiber.
G.652 single-modhi faibhaine kupararira kukuru muC-bhendi 1530 ~ 1565nm uye L-bhendi 1565 ~ 1625nm, kazhinji 17 ~ 22psnm • km, kana chiyero chehurongwa chasvika 2.5Gbit / s kana kupfuura, kuparadzirwa muripo kunodiwa, pa10Gbit / s Kupararira muripo mutengo weiyo sisitimu wakakwira, uye ndiyo yakajairika mhando yefiber yakaiswa mune yekutumira network parizvino.
Kupararira kweG.653 dispersion-shifted fibermuC-band neL-band inowanza -1～3.5psnm•km, ine zero dispersion pa1550nm, uye system rate inogona kusvika 20Gbit/s uye 40Gbit/s, inova imwe-wavelength ultra-long-distance. kutapurirana Iyo yakanakisa fiber.Zvisinei, nekuda kwe zero-dispersion feature, apo DWDM inoshandiswa pakuwedzera, zvisingabatsiri zvichaitika, zvinotungamirira kuchiratidzo chemuchinjikwa, zvichiita kuti ina-wave mixing FWM, saka DWDM haina kukodzera.
G.655 isiri-zero dispersion-shifted faibha: G.655 isina-zero dispersion-shifted fiber ine dispersion ye1 kusvika 6 psnm•km muC-band, uye kazhinji 6-10 psnm•km muL-band.Kupararira kudiki uye kunodzivirira zero.Iyo nzvimbo yekuparadzira haingodzvanyiriri iyo mana-wave kusanganisa FWM, inogona kushandiswa pakuwedzera kweDWDM, asi zvakare inogona kuvhura yakakwirira-kumhanya masisitimu.Iyo itsva G.655 fiber inogona kuwedzera nzvimbo inoshanda kusvika 1.5 kusvika 2 nguva yefiber yakajairika, uye nzvimbo huru inoshanda inogona kuderedza simba remagetsi!
