Na nchịkọta nke netwọk ozi ọgbara ọhụrụ, nzikọrịta ozi fiber optical na-ewere ọnọdụ kachasị.Site na mkpuchi na-arịwanye elu nke netwọk na mmụba na-aga n'ihu nke ikike nkwurịta okwu, mmelite nke njikọ nkwurịta okwu bụkwa mmepe a na-apụghị izere ezere.Ngwa anya modulnweta akara ngosi optoelectronic na netwọk nkwukọrịta anya.Ntughari bụ otu n'ime ihe ndị bụ isi nke nkwurịta okwu eriri anya.Otú ọ dị, anyị na-ekwukarị banyere modul anya.Yabụ, kedu ihe parampat nke modul anya?

Mgbe ọtụtụ afọ nke mmepe gasịrị, modul anya agbanweela nke ukwuu ụzọ nkwakọ ngwaahịa ha.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200/3000pin, XPAK, QAFP28, wdg bụ niile ụdị nkwakọ ngwaahịa modul;mgbe obere ọsọ, 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G na ọbụna 400G bụ nnyefe ọnụego nke ngwa anya modul.
Na mgbakwunye na paramita modul anya nkịtị, enwere ihe ndị a:

1. Ogologo ogologo nke etiti
Akụkụ nke ogologo wavele nke etiti bụ nanometer (nm), ugbu a enwere ụdị isi atọ:
1) 850nm (MM, multi-mode, ọnụ ala dị ala ma dị mkpirikpi nnyefe anya, n'ozuzu naanị 500m nnyefe);
2) 1310nm (SM, otu ọnọdụ, nnukwu ọnwụ ma obere mgbasa ozi n'oge nnyefe, nke a na-ejikarị maka nnyefe n'ime 40km);
3) 1550nm (SM, otu-mode, obere ọnwụ ma nnukwu mgbasa ozi n'oge nnyefe, a na-ejikarị eme ihe maka nnyefe dị anya n'elu 40km, na nke kachasị anya nwere ike ibunye ozugbo na-enweghị ọsọ ọsọ maka 120km).

2. Ogologo nnyefe
Ogologo nnyefe na-ezo aka n'ebe dị anya na enwere ike ibunye akara ngosi ozugbo na-enweghị nkwalite ọsọ agba anọ.Nkeji a bụ kilomita (a na-akpọkwa kilomita, km).Optical modul n'ozuzu nwere ndị a nkọwa: multi-mode 550m, otu-mode 15km, 40km, 80km, 120km, wdg Chere.

3. Mfu na mgbasa: Ha abụọ na-emetụta ebe nnyefe nke modul anya.N'ozuzu, a na-agbakọ ọnwụ njikọ ahụ na 0.35dBm / km maka 1310nm optical module, na njikọ njikọ na-agbakọọ na 0.20dBm / km maka 1550nm ngwa anya modul, na dispersion uru na-agbakọ dị nnọọ mgbagwoju anya, n'ozuzu maka ntụaka naanị;

4. Ọnwụ na mgbasa chromatic: A na-ejikarị paramita abụọ a kọwaa ebe nnyefe nke ngwaahịa ahụ.Ike nnyefe anya na ịnata uche nke modul anya nke dị iche iche nke ogologo wavelength dị iche iche, ọnụego nnyefe na anya nnyefe ga-adị iche;

5. Ụdị laser: Ugbu a, lasers ndị a na-ejikarị eme ihe bụ FP na DFB.Ihe semiconductor na usoro resonator nke abụọ dị iche iche.Laser DFB dị oke ọnụ ma na-ejikarị eme ihe maka modul anya nwere ebe nnyefe nke ihe karịrị 40km;mgbe FP lasers dị ọnụ ala, a na-ejikarị eme ihe maka modul anya nwere ebe nnyefe nke na-erughị 40km.

6. Optical fiber interface: SFP ngwa anya modul bụ ihe niile LC interfaces, GBIC ngwa anya modul bụ niile SC interfaces, na ndị ọzọ interfaces gụnyere FC na ST, wdg;

7. Ndụ ọrụ nke modul ngwa anya: ọkọlọtọ edo edo nke mba ụwa, awa 7 × 24 nke ọrụ na-akwụsịghị akwụsị maka awa 50,000 (nke dabara na afọ 5);

8. Environment: Ọnọdụ okpomọkụ na-arụ ọrụ: 0 ~ + 70 ℃;Nchekwa okpomọkụ: -45 ~ + 80 ℃;Voltage na-arụ ọrụ: 3.3V;Ọkwa ọrụ: TTL.
