Waa kuwee fiber indhaha loo isticmaalo dhismaha shabakada gudbinta?
Waxaa jira saddex nooc oo waaweyn: G.652 fiber hal-mode caadiga ah, G.653 kala firdhiyey hal-hab fiberd G.655 fiin aan eber ahayn oo kala firdhiyey.
G.652 hal qaab fiberwuxuu leeyahay kala firir weyn C-band 1530 ~ 1565nm iyo L-band 1565 ~ 1625nm, guud ahaan 17 ~ 22psnm•km, marka heerka nidaamka gaaro 2.5Gbit / s ama ka badan, kala firdhinta magdhowga ayaa loo baahan yahay, at 10Gbit/s Magdhawga Faafinta Qiimaha nidaamku waa mid aad u sarreeya, waana nooca ugu badan ee fiber-ka ee la dhigo shabakada gudbinta hadda.
Kala firdhiyeyG.653 firir-kala firdhiyeyC-band iyo L-band guud ahaan waa -1～3.5psnm•km, iyadoo eber kala firidhsan tahay 1550nm, heerka nidaamka wuxuu gaari karaa 20Gbit/s iyo 40Gbit/s, taas oo ah hal-mawjadaha ultra-dheer gudbinta Fiberka ugu fiican.Si kastaba ha ahaatee, iyada oo ay ugu wacan tahay sifadeeda kala firdhisan eber, marka DWDM loo isticmaalo balaadhinta, saamaynta aan tooska ahayn ayaa dhici doonta, taasoo horseedaysa calaamad isdhaafsi, taasoo keentay in afar-mawjadaha isku dhafan ee FWM, markaa DWDM kuma habboona.
G.655 aan eber ahayn fiber kala firdhisan oo beddeshay: G.655 aan eber kala firdhin-wareejin fiber wuxuu leeyahay kala firidhsan 1 ilaa 6 psnm•km ee C-band, iyo guud ahaan 6-10 psnm•km ee L-band.Kala firdhintu waa yar tahay waxayna ka fogaanaysaa eber.Aagga kala firidhsan ma aha oo kaliya inuu xakameeyo afarta-mawjadaha isku dhafka ah ee FWM, waxaa loo isticmaali karaa ballaarinta DWDM, laakiin sidoo kale waxay furi kartaa hababka xawaaraha sare leh.Fiber-ka cusub ee G.655 wuxuu ballaarin karaa aagga waxtarka leh ilaa 1.5 ilaa 2 jeer ka mid ah fiber-ka caadiga ah, iyo aagga weyn ee waxtarka leh wuxuu yarayn karaa cufnaanta awoodda!
