I-Fiber yemowudi enye: G652D vs G657A2

1/ Yintoni ifayibha yemowudi enye?

+ I-fiber yemowudi enye yi-fiber ye-optical eyenzelwe ukuthwala imowudi enye yokukhanya - imowudi enqamlezileyo.

+ Ifayibha ye-optical eqhelekileyo yemowudi enye inobubanzi obuphakathi kwe-8 ukuya kwi-10.5 μm (eqhelekileyo yi-9μm) kunye nobubanzi be-cladding obuyi-125 μm.

+ i-OS1 kunye ne-OS2 ziifayibha ezibonakalayo ze-optical ze-9/125 μm eziqhelekileyo. Zombini zisetyenziswa ngamaza obude obuyi-1310 nm kunye ne-1550 nm.

+ Ifayibha yemowudi enye yenzelwe ukudluliselwa komgama omde, ngesantya esiphezulu, ngokuqhelekileyo ixhasa umgama ukusuka kwi-2 km ukuya kwi-100–160 km.

+ Ulwakhiwo lwefayibha eqhelekileyo yemowudi enye:

Umongo:Ububanzi obuyi-8–9 μm

Ukubopha:Ububanzi obuyi-125 μm

I-Buffer:Ububanzi obuyi-250 μm

Ijakethi:Ububanzi obuyi-600 okanye i-900 μm

2/ G652D Ifayibha yemowudi enye:

+ G652D I-Single-mode Fiber lolona hlobo luqhelekileyo lwe-standard single-mode optical fiber (SMF), emiselwe yi-ITU-T yokunxibelelana ngesantya esiphezulu nomgama omde.

+ Isebenzisa iteknoloji "yokufikelela emanzini aphantsi", inciphisa ukulahleka kwesiginali kuluhlu lwamaza obude be-1383 nm.

+ Yaziwa ngokuba ne-bandwidth ephezulu, ukuncipha okuphantsi, kunye nokuhambelana okungasemva, ilungele iinethiwekhi zonxibelelwano, iiMetropolitan Area Networks (MAN), kunye nezicelo zeFiber to the Home (FTTH).

3/ G657A2 Ifayibha yemowudi enye:

+ G.657A2 I-Single-mode Fiber yi-fibre engagobiyo kakhulu, i-single-mode fiber ehambelana nemigangatho ye-ITU-T, eyenzelwe ukusebenza ngokulahleka okuncinci kwesignali kwi-tight bending radii (ephantsi njenge-7.5mm).

+ Ihambelana ngokupheleleyo nefayibha ye-G.652D, nto leyo eyenza ukuba ilungele iintambo ze-FTTH ezixineneyo, iintambo zangaphakathi, kunye nokufakelwa okuncinci, okune-radius ephezulu.
