    DDM ke eng mojulung oa optical?

    Nako ea poso: Dec-28-2022

    DDM (Digital Diagnostic Monitoring) ke theknoloji e sebelisoang ho li-module tsa optical. E sebelisetsoa ho hlahloba boemo ba ho sebetsa ba optical modules. Ke mokhoa oa 'nete oa ho lekola paramethara ea li-module tsa optical. E lumella basebedisi ho shebella litekanyetso tsa optical modules ka nako ea sebele, ho kenyelletsa le matla a optical a amoheloang, matla a optical a fetisitsoeng, mocheso o sebetsang, motlakase oa motlakase le laser bias current. Ebe, bapisa boleng bo shebiloeng le boleng ba boleng bo hlokoang ke optical module tlas'a maemo a tloaelehileng a ho sebetsa. Haeba e se sebakeng se hlokahalang, ho tla fanoa ka alamo. Haeba optical module e bontšoa e le boemong bo bobe, theswitjhae tla emisa ho romela data, 'me e ke ke ea romela kapa ea amohela data hape ho fihlela mochine oa optical o le boemong bo tloaelehileng.

    DDM ea optical module e sebetsa ho latela litekanyetso tse tloaelehileng tsa parameter tse hlalositsoeng ke protocol ea SFF-8472. Protocol ea SFF-8472 e totobatsa litekanyetso kapa mekhahlelo e tloaelehileng e lokelang ho lateloa ke software le hardware ea optical modules le lisebelisoa tsa marang-rang (tse kang li-switches), ho netefatsa ho sebelisana ha lihlahisoa tse fanoeng ke bafani ba thepa ea marang-rang ba fapaneng le bafani ba lisebelisoa tsa optical module. Ka bokhutšoanyane, sete sa li-parameter tsa OAM tse akaretsang li ka arolelanoa ke indasteri eohle ea puisano. Ke habohlokoa ho hlokomela hore ho nepahala ha lihlahisoa tse ling ho fetisitse litlhoko tsa tumellano. Tafole e latelang e bonts'a litekanyetso tsa parameter tsa protocol ea SFF-8472 bakeng sa li-module tsa optical.
