Li-fiber optic receiverle baamoheli ba module ya optical ke disebediswa tsa bohlokwa puisanong ya optical, empa di fapana ka mesebetsi, maemo a tshebediso le dibopeho.
1. Transceiver ea optic ea fiber:
Transceiver ea fiber optic ke sesebelisoa se fetolelang matšoao a optical hore e be matšoao a motlakase (pheletso e fetisang) kapa se fetolang matšoao a motlakase hore e be matšoao a optical (pheletso e amohelang). Li-transceiver tsa fiber optic li kopanya likarolo tse kang li-module tsa laser transmitter, li-converter tsa photoelectric, le bakhanni ba potoloho. Hangata li kenngoa ka har'a li-slots tsa module ea optical tsa lisebelisoa tsa marang-rang (joalo ka li-switch, li-router, li-server, jj.) ka har'a sephutheloana se tloaelehileng. Li-transceiver tsa fiber optic li sebelisoa ho fana ka phetoho ea matšoao pakeng tsa leseli le motlakase, 'me li bapala karolo ea ho fetisa matšoao nakong ea phetisetso ea data.
2. Transceiver ea module ea optical:
Transceiver ea module ea optical ke sesebelisoa sa optical se kopanyang transceiver ea fiber optic. Transceiver ea module ea optical hangata e na le sebopeho sa fiber ea optical, module ea ho romela lets'oao la optical (transmitter), le module ea ho amohela lets'oao la optical. Transceiver ea module ea optical e na le boholo bo tloaelehileng le sebopeho 'me e ka kenngoa ka har'a sekoti sa module ea optical lisebelisoa tsa marang-rang tse kang li-switch le li-routers. Transceiver ea module ea optical hangata e fanoa ka mokhoa oa module e ikemetseng bakeng sa ho e nkela sebaka habonolo, tlhokomelo le ntlafatso.
Melemo ea transceiver ea fiber optic le module ea optic
1. Transceiver ea optic ea fiber
Sebaka sa mosebetsi
E sebediswa bakeng sa phetoho ya matshwao a photoelectric (jwalo ka kou ya motlakase ya Ethernet ho ya kou ya optical), ho rarolla bothata ba kgokelo ya diphatlalatso tse fapaneng (thapo ya koporo ↔ faeba ya optical).
Hangata sesebelisoa se ikemetseng, se hloka phepelo ea motlakase ea kantle, 'me se fana ka likou tsa optical tse 1 ~ 2 le likou tsa motlakase (tse kang RJ45).
Boemo ba kopo
Atolosa sebaka sa phetiso: nkela thapo e hloekileng ea koporo sebaka, roba moeli oa limithara tse 100 (faeba ea optical ea mode e le 'ngoe e ka fihla ho feta 20km).
Katoloso ea marang-rang: hokela likarolo tsa marang-rang tsa mecha ea litaba e fapaneng (joalo ka marang-rang a khamphase, sistimi ea ho beha leihlo).
Tikoloho ea indasteri: ikamahanya le maemo a mocheso o phahameng le a matla a tšitiso ea motlakase (mehlala ea maemo a indasteri).
Melemo
Ho kenya le ho bapala: ha ho hlokahale tlhophiso, e loketse marangrang a manyane kapa phihlello e ka thoko.
Theko e tlase: e loketse lebelo le tlase le sebaka se sekhutšoanyane (joalo ka 100M/1G, fiber ea optical ea mekhoa e mengata).
Ho tenyetseha: e tšehetsa mefuta e mengata ea faeba (mokhoa o le mong/mokhoa o mongata) le bolelele ba maqhubu (850nm/1310nm/1550nm).
Meeli
Tshebetso e fokolang: Hangata ha e tshehetse lebelo le phahameng (jwalo ka ka hodimo ho 100G) kapa diprothokholo tse rarahaneng.
Boholo bo boholo: Lisebelisoa tse ikemetseng li nka sebaka.
2. Mojule oa Optical
Sebaka sa Mosebetsi
Di-interface tsa optical (tse kang di-slots tsa SFP le QSFP) tse kentsweng ka hara di-switch, di-router le disebediswa tse ding di phethela ka ho toba phetoho ya letshwao la optical-electrical.
Tšehetsa li-protocol tse lebelo le phahameng le tse nang le li-multi-speed (tse kang Ethernet, Fiber Channel, CPRI).
Maemo a kopo
Setsi sa data: khokahano e nang le bongata bo phahameng, e potlakileng haholo (joalo ka li-module tsa optical tsa 40G/100G/400G).
Marangrang a bajari ba 5G: ditlhoko tsa lebelo le phahameng le latency e tlase bakeng sa fronthaul le midhaul (jwalo ka di-module tsa optical tse putswa tsa 25G/50G).
Marangrang a mantlha: phetiso ya sebaka se selelele (jwalo ka di-module tsa DWDM tse nang le disebediswa tsa OTN).
Melemo
Tshebetso e phahameng: e tšehetsa sekhahla ho tloha ho 1G ho isa ho 800G, e fihlela maemo a rarahaneng a kang SDH le OTN.
E ka fetoloang ka ho tjhesa: e ka nkeloang sebaka ka mokhoa o tenyetsehang (joalo ka di-module tsa SFP+) bakeng sa ntlafatso le tlhokomelo e bonolo.
Moralo o monyane: kenya sesebelisoa ka ho toba ho boloka sebaka.
Meeli
Ho itshetlehile ka sesebediswa sa moamoheli: e tlameha ho tsamaellana le sebopeho le protocol ya switch/router.
Litšenyehelo tse phahameng: Li-module tse lebelo le phahameng (tse kang li-module tse kopaneng tsa optical) li theko e boima.
Ha re phethela
Li-transceiver tsa optic tsa fiberke disebediswa tse fetolelang matshwao a optical hore e be matshwao a motlakase kapa matshwao a motlakase hore e be matshwao a optical, mme hangata di kenngwa dibakeng tsa module ya optical;
Li-transceiver tsa module ea optical ke lisebelisoa tsa optical tse kopanyang li-transceiver tsa fiber optic, hangata li na le li-interface tsa fiber optic, li-transmitter le li-receiver. Moralo o ikemetseng oa li-transceiver tsa module ea optical. Li-transceiver tsa module ea optical ke foromo ea ho paka le mokhoa oa ts'ebeliso ea li-transceiver tsa fiber optic tse sebelisetsoang ho nolofatsa kopanyo le tsamaiso ea lisebelisoa tsa puisano ea optical.
