Marka la soo koobo shabakadaha macluumaadka casriga ah, isgaarsiinta fiber optic-ga ayaa ku jirta booska ugu sarreeya.Iyada oo la kordhinayo daboolida shabakada iyo kororka joogtada ah ee awoodda isgaarsiineed, hagaajinta isku xirka isgaarsiinta sidoo kale waa horumar lama huraan ah.Qaybaha indhahaku ogaan calaamadaha indhaha ee shabakadaha isgaarsiinta indhaha.Beddelku waa mid ka mid ah qaybaha ugu muhiimsan ee isgaarsiinta fiber optic.Si kastaba ha ahaatee, waxaan inta badan ka hadalnaa modules indhaha.Haddaba, waa maxay cabbirrada modules-yada indhaha?

Sannado badan oo horumarineed ka dib, modules-yada indhaha ayaa si weyn u beddelay hababka baakadaha.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200/3000pin, XPAK, QAFP28, iwm waa dhammaan noocyada baakadaha moduleka indhaha;halka xawaaraha hoose, 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G iyo xataa 400G yihiin heerka gudbinta ee modules indhaha.
Marka lagu daro cabbirada moduleka indhaha ee kor ku xusan, waxaa jira kuwan soo socda:

1. Mawjada dhexe
Unugga hirarka dhererka dhexe waa nanometer (nm), hadda waxaa jira saddex nooc oo waaweyn:
1) 850nm (MM, qaab-badan, qiimo jaban laakiin fogaanta gudbinta gaaban, guud ahaan kaliya gudbinta 500m);
2) 1310nm (SM, hal hab, khasaaro weyn laakiin kala firdhisan yar inta lagu guda jiro gudbinta, guud ahaan loo isticmaalo gudbinta gudahood 40km);
3) 1550nm (SM, hal-mode, khasaare hoose, laakiin kala firidhsan weyn inta lagu guda jiro gudbinta, guud ahaan loo isticmaalo gudbinta fogfog ka sarreeya 40km, iyo ka fog waxaa si toos ah la isugu gudbin karaa iyada oo aan Relay ah 120km).

2. Fogaanta gudbinta
Fogaanta gudbinta waxaa loola jeedaa fogaanta in calaamadaha indhaha si toos ah loo gudbin karo iyada oo aan la kordhinin gudbinta.Unuggu waa kiiloomitir (sidoo kale loo yaqaan kiiloomitir, km).Qaybaha indhaha guud ahaan waxay leeyihiin tilmaamo soo socda: qaab-badan 550m, hal-mode 15km, 40km, 80km, 120km, iwm. Sug.

3. Khasaare iyo kala firdhisanaan: Labaduba waxay inta badan saameeyaan fogaanta gudbinta ee moduleka indhaha.Guud ahaan, luminta isku xirka waxaa lagu xisaabiyaa 0.35dBm/km ee moduleka indhaha ee 1310nm, luminta isku xirka waxaa lagu xisaabiyaa 0.20dBm / km ee moduleka indhaha ee 1550nm, qiimaha kala firdhinta waxaa loo xisaabiyaa Aad u adag, guud ahaan tixraaca kaliya;

4. Khasaaraha iyo kala firdhisanaanta chromatic: Labadan xad waxaa inta badan loo isticmaalaa si loo qeexo fogaanta gudbinta alaabta.Awoodda gudbinta indhaha iyo helitaanka dareenka moodooyinka indhaha ee mawjadaha dhererka kala duwan, heerka gudbinta iyo fogaanta gudbintu way kala duwanaan doontaa;

5. Qaybta Laser: Waqtigan xaadirka ah, laser-yada ugu badan ee la isticmaalo waa FP iyo DFB.Qalabka semiconductor-ka iyo qaab-dhismeedka resonator-ka ee labaduba way kala duwan yihiin.Laysarka DFB waa qaali waxaana inta badan loo isticmaalaa modules indhaha oo leh masaafada gudbinta oo ka badan 40km;halka lasers-ka FP uu yahay mid raqiis ah, Guud ahaan loo isticmaalo modules-ka indhaha oo masaafo gudbineed ka yar 40km.

6. interface fiber indhaha: SFP modules indhaha waa dhammaan LC interfaces, GBIC modules indhaha waa dhammaan SC interfaces, iyo interfaces kale ka mid ah FC iyo ST, iwm;

7. Nolosha adeegga ee moduleka indhaha: heerka lebiska caalamiga ah, 7 × 24 saacadood oo shaqo aan kala go 'lahayn saacadaha 50,000 (oo u dhiganta 5 sano);

8. Deegaanka: Heerkulka shaqada: 0 ~ + 70 ℃;Heerkulka kaydinta: -45 ~ + 80 ℃;Korantada shaqada: 3.3V;Heerka shaqada: TTL.
