Ka kakaretso ea marang-rang a mehleng ea kajeno, puisano ea fiber optical e nka boemo bo ka sehloohong.Ka khaso e ntseng e eketseha ea marang-rang le keketseho e tsoelang pele ea matla a puisano, ntlafatso ea likhokahano tsa puisano le eona ke nts'etsopele e ke keng ea qojoa.Li-module tsa Opticalhlokomela matšoao a optoelectronic ho marang-rang a puisano a optical.Phetoho ke e 'ngoe ea likarolo tse ka sehloohong tsa puisano ea fiber ea optical.Leha ho le joalo, hangata re bua ka optical modules.Joale, li-parameter tsa optical modules ke life?

Kamora lilemo tsa nts'etsopele, li-module tsa optical li fetotse mekhoa ea tsona ea ho paka haholo.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200/3000pin, XPAK, QAFP28, joalo-joalo ke mefuta eohle ea liphutheloana tsa optical module;athe low-speed , 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G esita le 400G ke litekanyetso tsa phetisetso ea li-module tsa optical.
Ntle le li-parameter tse tloaelehileng tsa optical module, ho na le tse latelang:

1. Bophahamo ba maqhubu
Karolo ea bolelele ba sebaka sa bohareng ke nanometer (nm), hajoale ho na le mefuta e meraro ea mantlha:
1) 850nm (MM, mefuta e mengata, theko e tlaase empa sebaka se sekhutšoanyane sa phetisetso, hangata ke 500m feela ea phetisetso);
2) 1310nm (SM, mokhoa o le mong, tahlehelo e kholo empa ho hasana ho fokolang nakong ea phetisetso, ka kakaretso e sebelisetsoa phetisetso ka hare ho 40km);
3) 1550nm (SM, mokhoa o le mong, tahlehelo e tlase empa ho hasana ho hoholo nakong ea phetisetso, hangata e sebelisetsoa phetiso ea sebaka se selelele ka holimo ho 40km, 'me e hōle ka ho fetisisa e ka fetisoa ka ho toba ntle le relay bakeng sa 120km).

2. Sebaka sa phetiso
Sebaka sa phetiso se bolela sebaka seo mats'oao a optical a ka fetisetsoang ka kotloloho ntle le ho phahamisa matla.Sehlopha ke lik'hilomithara (hape li bitsoa kilometers, km).Li-module tsa Optical ka kakaretso li na le litlhaloso tse latelang: mefuta e mengata ea 550m, mokhoa o le mong 15km, 40km, 80km, 120km, joalo-joalo Ema.

3. Tahlehelo le ho hasana: Ka bobeli li ama haholo sebaka sa phetisetso ea mojule oa optical.Ka kakaretso, tahlehelo ea li-link e baloa ho 0.35dBm / km bakeng sa 1310nm optical module, 'me tahlehelo ea khokahanyo e baloa ho 0.20dBm / km bakeng sa 1550nm optical module,' me boleng ba ho hasana bo baloa bo rarahane haholo, ka kakaretso bakeng sa ho buuoa feela;

4. Tahlehelo le phallo ea chromatic: Litekanyetso tsena tse peli li sebelisoa haholo ho hlalosa sebaka sa phetisetso ea sehlahisoa.Matla a phetisetso ea optical le ho amohela kutloisiso ea li-module tsa optical tsa wavelengths tse fapaneng, litefiso tsa phetisetso le libaka tsa phetisetso li tla fapana;

5. Sehlopha sa Laser: Hajoale, lisebelisoa tsa laser tse sebelisoang haholo ke FP le DFB.Lisebelisoa tsa semiconductor le sebopeho sa resonator tsa tse peli li fapane.Li-laser tsa DFB li theko e boima 'me hangata li sebelisetsoa li-module tsa optical tse nang le sebaka sa phetisetso se fetang 40km;ha li-lasers tsa FP li le theko e tlase, Ka kakaretso li sebelisetsoa li-module tsa optical tse nang le sebaka sa phetisetso se ka tlase ho 40km.

6. Optical fiber interface: SFP optical modules kaofela ha LC interfaces, GBIC optical modules ke SC interfaces kaofela, 'me li-interfaces tse ling li kenyelletsa FC le ST, joalo-joalo;

7. Bophelo ba tšebeletso ea mochine oa optical: tekanyetso ea machaba ea junifomo, lihora tse 7 × 24 tsa mosebetsi o sa sitisoeng bakeng sa lihora tsa 50,000 (tse lekanang le lilemo tse 5);

8. Tikoloho: Mocheso o sebetsang: 0~+70℃;Mocheso oa polokelo: -45 ~ + 80 ℃;Matla a sebetsang: 3.3V;Boemo ba ho sebetsa: TTL.
