G.652D Hal-hab fiber indhaha (B1.3)-Fasalka B

G.652D Hal-mode fiber indhaha ah (B1.3) -Darajada B Sawirka leh

Sharaxaad Gaaban:

Biyo hooseeya oo aan kala firdhin barakicin hal-qaab fiber ah ayaa ku habboon nidaamka gudbinta ee band buuxa 1280nm ~ 1625nm, kaas oo aan kaliya ilaalinayn kala firdhinta hoose ee kooxda dhaqameed ee 1310nm, laakiin sidoo kale waxay leedahay khasaare hoose 1383nm, taasoo ka dhigaysa E band (1360nm ~ 1460nm) si buuxda ayaa loo isticmaalay. Luminta iyo kala firdhinta kooxda oo dhan laga bilaabo 1260nm ilaa 1625nm ayaa la wanaajiyey, luminta luminta hirarka dhererka 1625nm waa la dhimay, taas oo bixisa ilaha bandwidth ee shabakada laf dhabarta, MAN iyo marin u helka.

Tilmaamaha Alaabta

● Tusmada ugu sarreysa biyaha hoose ee aan kala firdhin-wareejin hal-hab fiber ayaa ka wanaagsan ITU-T oo lagu taliyay G.652D iyo IEC B1.3 tifaftirka farsamada fiber;

● Waxqabadka indhaha ee heer sare ah, wuxuu qancin karaa waxtarka sare ee DWDM iyo gudbinta shuruudaha nidaamka CWDM;

● Cabbirka joomatari ee heer sare ah, si loo hubiyo alxanka khasaaraha hooseeya iyo waxqabadka xidhidhiyaha sare;

● Isku-dhafka hooseeya ee PMD, qanciya nidaamka gudbinta fogaanta dheer iyo waxtarka sare.

Wax soo saarka alaabta

Codsiga Alaabta

1. Ku habboon dhammaan noocyada qaab dhismeedka fiilada fiber optic: nooca tube beam dhexe, lakabka gacanta dabacsan nooca xayiran, nooca qalfoofka, qaab-dhismeedka fiilada fiber optic;

2. Codsiyada fiber indhaha waxaa ka mid ah: nidaamyada fiber indhaha u baahan khasaare hoose iyo bandwidth sare, sida isgaarsiinta fogfog, khadadka jirridda, feederayaasha loop, khadadka qaybinta iyo cable TV, iwm, gaar ahaan ku haboon 1383nm band qalafsan kala dhufashada kala qaybinta hirarka dhererka. CWDM), multiplexing qaybinta mowjadda cufan (DWDM) iyo isticmaalka deegaan gaar ah oo kala duwan (tusaale, Hillaac-caddayn OPGW cable indhaha, ADSS cable indhaha, iwm), fiber indhaha iyada oo qalab daahan iftiin gaar ah iyo habka daahan iyo ka dib processing, si waxay leedahay wax qabad aad u sarreeya oo ku saabsan sifooyinka farsamada iyo heerkulka sare ee waxqabadka deegaanka.
