    Tlhaloso e qaqileng ea SFP optical module interface indicators le likarolo

    Nako ea poso: Jun-02-2020

    Lebelo la SFP + ea optical module ke: 10G SFP + transceiver optical ke ntlafatso ea SFP (ka linako tse ling e bitsoa "mini-GBIC"). SFP e sebelisitsoe haholo ho Gigabit Ethernet le 1G, 2G, le 4G Fiber Channel. E le ho ikamahanya le litekanyetso tse phahameng tsa data, SFP + e ntlafalitse ts'ireletso ea motlakase ea motlakase le litšobotsi tsa tlhokomelo ea matšoao ho feta SFP, 'me e thehile litlhaloso tse ncha tsa motlakase.

    Lenane la sefahleho sa SFP optical module

    1. Matla a ho hlahisa matla a matla a matla a optical a bolela matla a optical a hlahisoang ke mohloli oa leseli qetellong ea ho romela mochine oa optical, unit: dBm.

    2. Matla a optical a amohetseng Matla a optical a amohetseng a bolela matla a optical a amohetseng qetellong ea mochine oa optical, unit: dBm.

    3. Amohela kutlo Amohela kutlo e bolela matla a bonyane a amohetsweng a optical a module optical ka sekhahla se itseng le sekgahla sa phoso, ho dBm. Tlas'a maemo a tloaelehileng, tekanyo e phahameng, e mpe le ho feta ea kutloisiso ea ho amohela, ke hore, matla a fokolang a amohelehang a optical, a phahamisa litlhoko tsa mochine o amohelang mochine oa optical.

    4. Saturated optical power, eo hape e tsejoang e le optical saturation, e bolela boholo ba matla a optical a kentsoeng ha sekhahla se itseng sa phoso (10-10).10-12) e bolokiloe ka sekhahla se itseng sa phetiso.

    Re lokela ho hlokomela hore photodetector e tla tlatsa photocurrent tlas'a leseli le matla. Ha ketsahalo ena e etsahala, detector e hloka nako e itseng ea ho hlaphoheloa. Ka nako ena, kutloisiso ea ho amohela e ea fokotseha mme lets'oao le amoheloang le ka ahloloa hampe. E baka liphoso tse nyenyane, 'me ho bonolo haholo ho senya mochine oa ho amohela. Ha e sebelisoa, e lokela ho leka ho thibela ho feta matla a eona a saturated optical.

    Hlokomela hore bakeng sa li-module tsa nako e telele tsa optical, kaha karolelano ea matla a optical e matla ka kakaretso e kholo ho feta matla a eona a saturated optical, ka kopo ela hloko bolelele ba fiber ha u e sebelisa ho netefatsa hore matla a optical a amohetseng a fihla ho optical module. e ka tlase ho matla a eona a mahlo a tletseng. Optical module e senyehile.

    Likarolo tsa SFP optical modules

    Sebopeho sa SFP optical module ke: laser: ho kenyelletsa le transmitter TOSA le moamoheli ROSA boto ea potoloho IC, le lisebelisoa tse kantle ke: khetla, setsi, PCBA, selikalikoe sa ho hula, buckle, sengoathoana sa ho notlolla, plug ea rabara. Ho phaella moo, bakeng sa boitsebiso bo bonolo, Ka kakaretso, mofuta oa parameter ea mojule o khetholloa ka 'mala oa lesale la ho hula. Mohlala: selikalikoe se ntšo sa ho hula se na le mefuta e mengata, bolelele ba maqhubu ke 850nm; boputsoa ke module e nang le wavelength ea 1310nm; mosehla ke module e nang le wavelength ea 1550nm; pherese ke mojule o nang le bolelele ba 1490nm.

    SFP, SFF le GBIC optical module kamano

    SFP ke khutsufatso ea li-Pluggables tsa Small Form-factor, ke hore, mojule o monyane oa pluggable optical optical package. SFP e ka nkuoa e le mofuta o ka khonehang oa SFF. Sebopeho sa eona sa motlakase ke monoana oa khauta oa 20-pin. Sebopeho sa lets'oao la data ha e le hantle se tšoana le mojule oa SFF. SFP module e boetse e fana ka sebopeho sa taolo ea I2C, se lumellanang le SFP-8472 standard optical interface diagnostics. Ka bobeli SFF le SFP ha li kenyelle karolo ea SerDes, 'me li fana feela ka sebopeho sa serial data. CDR le matšeliso a phallo ea motlakase li behiloe ka ntle ho mojule, ho etsa hore boholo bo fokolang le tšebeliso e tlaase ea matla e khonehe. Ka lebaka la ho fokotsa mocheso oa mocheso, SFF/SFP e ka sebelisoa feela bakeng sa sebaka se khuts'oane haholo, sebaka se sekhuts'oane le lits'ebetso tsa sebaka se mahareng ho 2.5Gbps le tlase.

    Li-module tsa SFP optical hona joale li na le lebelo le phahameng la 10G, 'me boholo ba tsona li sebelisa li-interface tsa LC. E ka utloisisoa habonolo e le mofuta o ntlafalitsoeng oa GBIC. Molumo oa SFP optical modules o fokotsehile ka halofo ha o bapisoa le GBIC optical modules, 'me ho feta habeli palo ea likou e ka lokisoa phanele e le 'ngoe. Mabapi le mesebetsi e meng, motheo oa SFP module o tšoana le GBIC. Ka hona, ba bangswitjhabaetsi ba bitsa SFP optical modules miniaturized GBIC.
