I-Fiber yemodi eyodwa: G652D vs G657A2

1/ Iyini i-fiber yemodi eyodwa?

+ I-fiber yemodi eyodwa iyi-fiber ebonakalayo eyenzelwe ukuthwala imodi eyodwa yokukhanya - imodi ephambeneyo.

+ I-fiber optical ejwayelekile yemodi eyodwa inobubanzi obuphakathi kuka-8 kuya ku-10.5 μm (okuvamile kungu-9μm) kanye nobubanzi bokumboza obungu-125 μm.

+ OS1 kanye ne-OS2 ziyi-fiber optical ejwayelekile engu-9/125 μm enemodi eyodwa. Zombili zisetshenziswa ngamaza obubanzi angu-1310 nm kanye no-1550 nm.

+ I-fiber yemodi eyodwa yenzelwe ukudluliselwa kwebanga elide, okushesha kakhulu, ngokuvamile okusekela amabanga ukusuka ku-2 km kuya ku-100–160 km.

+ Isakhiwo sefayibha ejwayelekile yemodi eyodwa:

Umongo:Ububanzi obungu-8–9 μm

Ukubopha:Ububanzi obungu-125 μm

I-Buffer:Ububanzi obungu-250 μm

Ijakethi:Ububanzi obungu-600 noma 900 μm

2/ G652D I-Fiber yemodi eyodwa:

+ I-G652D I-Fiber yemodi eyodwa uhlobo oluvame kakhulu lwe-fiber optical yemodi eyodwa ejwayelekile (i-SMF), ebekwe yi-ITU-T yokuxhumana okusheshayo nokude.

+ Ifaka ubuchwepheshe "be-low water peak", okunciphisa ukulahleka kwesiginali ebangeni lamaza obubanzi obungu-1383 nm.

+ Yaziwa nge-bandwidth ephezulu, ukuncipha okuphansi, kanye nokuhambisana emuva, ilungele amanethiwekhi okuxhumana, amanethiwekhi eMetropolitan Area (MAN), kanye nezinhlelo zokusebenza ze-Fiber to the Home (FTTH).

3/ G657A2 I-Fiber yemodi eyodwa:

+ I-G.657A2 I-Fiber yemodi eyodwa iyi-fiber engazweli kakhulu ekugobeni, ehambisana nezindinganiso ze-ITU-T, eyenzelwe ukusebenza ngokulahlekelwa okuncane kwesiginali kuma-radii agobile aqinile (aphansi njengo-7.5mm).

+ Ihambisana ngokugcwele nefayibha ye-G.652D, okwenza ifaneleke kakhulu kumakhebula okudonsa e-FTTH aqinile, izintambo zangaphakathi, kanye nokufakwa kwe-radius enesikhala esincane negobile kakhulu.
