Optical modules le optical fiber transceivers ke lisebelisoa tse etsang phetoho ea photoelectric.Phapano ke efe pakeng tsa tsona?Matsatsing ana, phetiso ea data ea nako e telele e sebelisoang mererong e mengata e bohlale e sebelisa phetiso ea fiber ea optical.Khokahano lipakeng tsa sena e hloka li-module tsa optical le li-transceivers tsa fiber optic.Kahoo, tse peli tsee li lokela ho hokahanngoa joang, ’me ke eng e lokelang ho eloa hloko?
1. Optical module
Mosebetsi oa mochine oa optical hape ke phetoho pakeng tsa matšoao a photoelectric.E sebelisoa haholo-holo bakeng sa mojari pakeng tsa switjha le sesebelisoa.E na le molao-motheo o tšoanang le optical fiber transceiver, empa optical module e sebetsa hantle ebile e sireletsehile ho feta transceiver.Li-module tsa optical li arotsoe ho latela foromo ea sephutheloana.Tse tloaelehileng li kenyelletsa SFP, SFP +, XFP, SFP28, QSFP +, QSFP28, joalo-joalo.
2. Transceiver ea fiber ea optic
Optical fiber transceiver ke sesebelisoa se fetolang mats'oao a motlakase a sebaka se khuts'oane le mats'oao a mahlo a malelele.Ka kakaretso e sebelisoa phetisong ea sebaka se selelele, e fetisa ka likhoele tsa optical, ho fetola matšoao a motlakase hore e be lipontšo tsa optical le ho li romella.Letšoao la optical le amoheloang le fetoloa letšoao la motlakase.E boetse e bitsoa Fiber Converter libakeng tse ngata.
Li-transceivers tsa fiber optic li fana ka tharollo e theko e tlaase bakeng sa basebelisi ba hlokang ho ntlafatsa tsamaiso ho tloha terata ea koporo ho ea ho fiber optics, empa ba haelloa ke chelete, basebetsi kapa nako.
3. Phapang pakeng tsa optical module le optical fiber transceiver
① E sebetsang le e sa sebetseng: Mojule oa optical ke mochini o sebetsang, kapa sesebelisoa, ke sesebelisoa se ke keng sa sebelisoa se le seng, 'me se sebelisoa feela ho li-switches le lisebelisoa tse nang le optical module slots;optical fiber transceivers ke lisebelisoa tse sebetsang.Ke sesebelisoa se sebetsang se arohaneng, se ka sebelisoang se le seng ha se kenngoa;
②Ho ntlafatsa tlhophiso: Mojule oa optical o tšehetsa phetoho e chesang, tlhophiso e batla e fetoha;optical fiber transceiver e batla e tsitsitse, 'me ho nkela sebaka le ho ntlafatsa ho tla ba thata haholoanyane;
③Theko: Li-transceivers tsa fiber optical li theko e tlase ho feta li-module tsa optical mme li batla li na le chelete ebile lia sebetsa, empa hape li hloka ho nahana ka lintlha tse ngata joalo ka adaptara ea motlakase, boemo bo bobebe, boemo ba thapo ea marang-rang, joalo-joalo, mme tahlehelo ea phetisetso e baka hoo e ka bang 30%;
④Kopo: Li-module tsa Optical li sebelisoa haholo ho lisebelisoa tsa puisano tsa marang-rang, tse kang li-interfaces tsa optical tsa li-switches, li-router tsa mantlha, DSLAM, OLT le lisebelisoa tse ling, tse kang: video ea k'homphieutha, puisano ea data, puisano ea lentsoe la mohala le mokokotlo o mong oa fiber optical network;optical fiber transceiver E sebelisoa sebakeng sa sebele sa marang-rang moo mohala oa Ethernet o ke keng oa koahela 'me o tlameha ho sebelisa fiber ea optical ho atolosa sebaka sa phetisetso,' me hangata e behiloe e le ts'ebeliso ea lera la ho fihlella la marang-rang a marang-rang a marang-rang a marang-rang;
4. Ke eng e lokelang ho lefshoa ha u kopanya mochine oa optical le transceiver optical fiber?
① Lebelo la optical module le transceiver ea fiber ea optical li tlameha ho tšoana, megabyte tse 100 ho isa ho 100 megabytes, gigabit ho gigabit, le 10 megabytes ho 10 trillion.
② Bolelele ba maqhubu le sebaka sa phetiso e tlameha ho ts'oana, mohlala, bolelele ba maqhubu ke 1310nm kapa 850nm ka nako e le 'ngoe,' me sebaka sa phetiso ke 10km;
③ Mofuta oa leseli o tlameha ho tšoana, fiber e le 'ngoe ho fiber e le' ngoe, fiber e habeli ho ea ho tse peli.
④ Li-jumpers kapa li-pigtails li tlameha ho hokahanngoa ka sebopeho se tšoanang.Ka kakaretso, li-transceivers tsa fiber optic li sebelisa likou tsa SC le li-module tsa optical li sebelisa likou tsa LC.
