Umehluko phakathi kwe-dual fibre optical module kanye ne-single fibre optical module

1. Ukubukeka okuhlukile:

I-double fiber optical module: Kunamasokhethi amabili efiber optical, ngokulandelanayo, ukuthumela (TX) kanye nokwamukela (RX) izimbobo zokubuka. Kudingeka kufakwe imicu emibili ye-optical, futhi izimbobo ze-optical ezahlukene kanye nemicu yokubona isetshenziselwa ukudluliswa kwedatha nokwamukela; Uma kusetshenziswa amamojula we-fiber optical amabili, ubude be-wavelength bamamojula optical kuzo zombili iziphetho kufanele buhambisane.

I-Single fiber optical module: kunesokhethi eyodwa kuphela ye-fiber optical, eyabiwa ngokuthumela nokwamukela. I-optical fibre eyodwa idinga ukufakwa, futhi imbobo ye-optical efanayo kanye ne-optical fiber transmission isetshenziselwa ukwamukela nokuthumela idatha; Uma usebenzisa i-fiber optical module eyodwa, ubude be-wavelength bamamojula optical kuzo zombili iziphetho kufanele bufane, okungukuthi, i-TX/RX iphambene.

2. Amaza amaza avamile ahlukene: i-fiber module eyodwa inamaza amaza amabili ahlukene okuthumela nokwamukela, kuyilapho i-dual fiber module inobude obubodwa kuphela;

Ubude obujwayelekile be-fiber kabili: 850nm 1310nm 1550nm

Amaza amaza avamile we-fiber eyodwa ikakhulukazi ahlanganisa okulandelayo:

I-Gigabit fiber eyodwa:

TX1310/RX1550nm

TX1550/RX1310nm

TX1490/RX1550nm

TX1550/RX1490nm

TX1310nm/Rx1490nm

TX1490nm/Rx1310nm

I-10 Gigabit fiber eyodwa:

TX1270nm/RX1330nm

TX1330nm/RX1270nm

TX1490nm/RX1550nm

TX1550nm/RX1490nm

3. Isivinini esihlukile: uma kuqhathaniswa ne-dual fiber optical module, i-single fibre optical module inezinhlobonhlobo zezinhlelo zokusebenza ku-100 megabit, i-gigabit kanye nesivinini se-gigabit engu-10; Akuvamile ku-40G kanye ne-100G yokudlulisela ngesivinini esikhulu.
