Mwachidule cha maukonde amakono azidziwitso, optical fiber communication imatenga malo apamwamba.Chifukwa cha kuchuluka kwa ma netiweki komanso kuchuluka kwa njira zolumikizirana mosalekeza, kuwongolera kwa maulalo olumikizirana ndichinthu chomwe sichingalephereke.Ma module a Opticalkuzindikira ma optoelectronic ma sign mu ma network olumikizana.Kutembenuka ndi chimodzi mwa zigawo zikuluzikulu za kuwala CHIKWANGWANI kulankhulana.Komabe, nthawi zambiri timalankhula za ma module optical.Ndiye, ndi magawo otani a ma module optical?

Pambuyo pazaka za chitukuko, ma module optical asintha kwambiri njira zawo zopangira.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200/3000pin, XPAK, QAFP28, etc. ndi mitundu yonse yopangira ma module optical;pamene low-speed , 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G ngakhale 400G ndi maulendo opatsirana a ma modules optical.
Kuphatikiza pa magawo omwe ali pamwambawa optical module, pali awa:

1. Kutalika kwapakati
Gawo la kutalika kwapakati ndi nanometer (nm), pakadali pano pali mitundu itatu yayikulu:
1) 850nm (MM, Mipikisano mode, otsika mtengo koma lalifupi kufala mtunda, zambiri kufala 500m);
2) 1310nm (SM, mode limodzi, kutaya kwakukulu koma kubalalitsidwa kochepa panthawi yopatsirana, yomwe imagwiritsidwa ntchito pofalitsa mkati mwa 40km);
3) 1550nm (SM, single-mode, kutayika kochepa koma kubalalitsidwa kwakukulu panthawi yopatsirana, komwe kumagwiritsidwa ntchito kufalitsa mtunda wautali pamwamba pa 40km, ndipo kutali kwambiri kumatha kufalikira popanda kutumizirana ma 120km).

2. Mtunda wotumizira
Kutalikirana kumatanthawuza mtunda womwe ma siginecha amawu amatha kutumizidwa mwachindunji popanda kukulitsanso.Chigawocho ndi makilomita (amatchedwanso makilomita, km).Ma module a kuwala nthawi zambiri amakhala ndi zotsatirazi: 550m mode, single-mode 15km, 40km, 80km, 120km, etc. Dikirani.

3. Kutayika ndi kubalalitsidwa: Zonsezi zimakhudza kwambiri mtunda wotumizira wa module optical.Kawirikawiri, kutayika kwa ulalo kumawerengedwa pa 0.35dBm / km kwa 1310nm optical module, ndipo kutayika kwa chiyanjano kumawerengedwa pa 0.20dBm / km kwa 1550nm optical module, ndipo mtengo wobalalika umawerengedwa Wovuta kwambiri, kawirikawiri kuti afotokoze kokha;

4. Kutayika ndi kubalalitsidwa kwa chromatic: Magawo awiriwa amagwiritsidwa ntchito makamaka kutanthauzira mtunda wotumizira wa chinthucho.Mphamvu yotumizira kuwala ndi kulandira kukhudzidwa kwa ma modules optical a wavelengths osiyana, maulendo opatsirana ndi maulendo opatsirana adzakhala osiyana;

5. Gulu la laser: Pakali pano, ma laser omwe amagwiritsidwa ntchito kwambiri ndi FP ndi DFB.Zida za semiconductor ndi mawonekedwe a resonator a awiriwa ndi osiyana.Ma laser a DFB ndi okwera mtengo ndipo amagwiritsidwa ntchito kwambiri pama module owoneka ndi mtunda wopitilira 40km;pomwe ma laser a FP ndi otsika mtengo, Amagwiritsidwa ntchito ngati ma module owoneka bwino okhala ndi mtunda wosakwana 40km.

6. Mawonekedwe a fiber optical: SFP optical modules ndi LC interfaces, GBIC optical modules ndi SC interfaces, ndi mawonekedwe ena akuphatikizapo FC ndi ST, etc.;

7. Moyo wautumiki wa module ya optical: yunifolomu yapadziko lonse, 7 × 24 maola osasokonezeka kwa maola 50,000 (ofanana ndi zaka 5);

8. Chilengedwe: Kutentha kwa ntchito: 0 ~ + 70 ℃;Kutentha kosungira: -45 ~ + 80 ℃;Mphamvu yogwira ntchito: 3.3V;Mulingo wogwira ntchito: TTL.
