Mehato ea ho kenya
1. Pele o kenya lisebelisoa, ka kopo bala ka hloko 'me u kenye lisebelisoa ho ea ka .Tlhokomeliso: Bakeng sa tšenyo e entsoeng ke motho le litlamorao tse ling tse bakiloeng ke ho kenya liphoso tse sa lumellaneng le , re ke ke ra ba le boikarabello ebile re ke ke ra fana ka tiisetso ea mahala.
2. Ntša sesebelisoa lebokoseng;e lokise ka rack le ka tšeptjoang fatše.(Ho hanyetsa fatše ho tlameha ho ba <4Ω).
3. Sebelisa multimeter ea digital ho hlahloba motlakase oa phepelo, etsa bonnete ba hore motlakase oa phepelo o lumellana le litlhoko le senotlolo sa ho fetola se sebakeng sa "OFF".Ebe o hokahanya phepelo ea motlakase.
4. Kenya letshwao la optical ho latela molaetsa wa pontsho.Tobetsa konopo ho "ON" 'me u shebe boemo ba phanele ea LED.Ka mor'a hore pontšo ea boemo ba pompo e fetohe e tala, sesebelisoa se sebetsa ka mokhoa o tloaelehileng.Ebe o tobetsa konopo ea menu ho phanele e ka pele ho hlahloba li-parameter tse sebetsang.
5. Kopanya meter ea matla a optical ho ea qetellong ea pontšo ea optical ka jumper e tloaelehileng ea optical fiber test, ebe o lekanya matla a optical output.Netefatsa matla a optical a lekantsoeng le matla a bonts'itsoeng a ts'oana mme a fihletse boleng ba lebitso.(Tiisa hore meter ea matla a optical e boemong ba teko ea 1550nm wavelength; jumper optical fiber test jumper ke e ts'oanang 'me holim'a sehokelo ha ho na tšilafalo.) Tlosa jumper e tloaelehileng ea optical fiber test le meter ea matla a optical;hokela sesebediswa ho netweke.Ho fihlela joale, sesebelisoa se kentsoe ka ho feletseng le ho lokisoa.
