Sesebelisoa sa CWDM
Tlhaloso ea Sehlahisoa
CWDM-55 ke 1550nm CWDM mux kapa sesebelisoa sa demux se nang le filthara e hahelletsoeng ka 1550nm e eketsang lets'oao la 1550nm boema-kepeng kapa ho theola lets'oao la 1550nm ho tsoa boema-kepeng. Sesebelisoa sa letoto la CWDM-xx se loketse ho eketsa kapa ho theola mocha oa xx CWDM ho sistimi ea fiber optic. Leqhubu le tloaelehileng la CWDM ho tloha 1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1450nm, 1450nm, 40m1 1530nm, 1550nm, 1570nm, 1590nm ho isa 1610nm, moo 1310nm le 1490nm e leng GPON 2-way optical wavelengths bakeng sa fiber ho ea lapeng, 1550nm ke mokhoa o tloaelehileng oa ho hasanya oavelength ka ts'ebeliso ea amplifier ea optical fiber. Sesebediswa sa kamehla sa Nch CWDM mux kapa de-mux ke ho bokella lisebelisoa tsa filthara e le 'ngoe ea N-1 ea cascading CWDM.
Puisano ea fiber optic e fetotse polanete ena ho tloha ka bo-1980. Fiber ea mode e le 'ngoe e na le melemo ea tlhokomelo e bonolo, ho fokotseha ho tlaase, sebaka se sephara sa optical wavelength le data ea lebelo le phahameng ho leqhubu le leng le le leng la optical. Ho phaella moo, fiber e na le botsitso bo phahameng ho fetoha ha mocheso le libaka tse sa tšoaneng. Likhokahano tsa fiber optic li bapala karolo ea bohlokoa ho tloha ho phapanyetsano ea tlhahisoleseling ho isa ho boithabiso ba lelapa. Lisebelisoa tsa WDM, li-splitter tsa Fiber le li-patchcords tsa fiber ke likarolo tsa bohlokoa ho passive optical network (PON), e tšehetsang maqhubu a mangata a marang-rang a sebetsang ho tloha ntlheng e le 'ngoe ho isa lits'ebetsong tse peli tse fapaneng. Hammoho le lintlafatso tse mabapi le likarolo tse sebetsang tse kang laser, photodiode, APD le amplifier ea optical, likaroloana tsa fiber optic tse etsang hore thapo e fumanehe monyako oa lehae la ba ngolisitseng ka theko e tlase. Marang-rang a lebelo le phahameng, likhaso tse kholo tsa video tsa HD ka fiber li etsa hore polanete ena e be nyane.
Sesebelisoa sa CWDM se ka sebelisoa e le sesebelisoa se ikemetseng kapa se kenngoa ka har'a laser le photodiode. Sephutheloana se tsebahalang ke li-fiber pigtail tube tse tharo, lebokose la polasetiki la cassette, LGX housing le 19” 1RU chassis.

Likarolo tse ling:
• Bandwidth ea kanale e pharalletseng.
• Botsitso bo Phahameng le Botšepehi.
• Epoxy-Free ho Optical Path.
