    Isesengura rirambuye rya SFP optique module yerekana ibipimo nibigize

    Igihe cyo kohereza: Jun-02-2020

    Umuvuduko wa module optique SFP + ni: 10G SFP + transceiver optique ni ukuzamura SFP (rimwe na rimwe bita "mini-GBIC"). SFP yakoreshejwe cyane kuri Gigabit Ethernet na 1G, 2G, na 4G Fibre. Kugirango uhuze n’ibipimo biri hejuru yamakuru, SFP + yateguye uburyo bwogukingira amashanyarazi hamwe no kubungabunga ibimenyetso kuruta SFP, kandi yashyizeho uburyo bushya bwo gukoresha amashanyarazi.

    Imigaragarire yimbere ya SFP optique module

    2. Imbaraga za optique zakiriwe Imbaraga za optique zisobanura imbaraga za optique zakiriwe kumpera yakira ya module optique, unit: dBm.

    3. Kwakira ibyiyumvo Kwakira ibyiyumvo byerekana imbaraga nkeya yakiriwe ya optique ya optique ya module ya optique ku gipimo runaka nigipimo cyamakosa, muri dBm. Mubihe bisanzwe, uko igipimo kiri hejuru, niko birushaho kuba bibi kwakira sensibilité, ni ukuvuga, nini nini yakiriye imbaraga za optique, niko bisabwa kubikoresho byakira ibikoresho bya optique.

    4. Imbaraga zuzuye za optique, zizwi kandi kwizina rya optique, bivuga imbaraga nyinshi zinjiza optique mugihe igipimo runaka cyamakosa (10-1010-12) ikomezwa ku gipimo runaka cyo kohereza.

    Twabibutsa ko Photodetector izuzuza fotokore munsi yumucyo ukomeye. Iyo ibi bibaye, detector ikenera igihe runaka kugirango ikire. Muri iki gihe, kwakira ibyiyumvo biragabanuka kandi ibimenyetso byakiriwe birashobora gufatwa nabi. Itera amakosa bito, kandi biroroshye cyane kwangiza imashini yakira. Mugukoresha, igomba kugerageza kwirinda kurenza imbaraga zuzuye za optique.

    Menya ko kubirebire birebire bya optique, kubera ko impuzandengo isohora ingufu za optique muri rusange iruta imbaraga zayo zuzuye, nyamuneka witondere uburebure bwa fibre mugihe uyikoresheje kugirango umenye neza ko imbaraga za optique zakiriwe zigera kuri optique ni munsi yububasha bwuzuye bwa optique. Moderi ya optique yangiritse.

    Ibigize SFP optique module

    Ibigize moderi ya optique ya SFP ni: laser: harimo na transmitter TOSA hamwe niyakira ROSA ikibaho cyumuzunguruko IC, hamwe nibikoresho byo hanze ni: shell, base, PCBA, gukurura impeta, buckle, gufungura igice, reberi. Mubyongeyeho, kugirango byoroshye kumenyekana, Mubisanzwe, ibipimo byubwoko bwa module bigaragazwa nibara ryikurura. Kurugero: impeta yumukara ikurura nuburyo bwinshi, uburebure bwumurongo ni 850nm; ubururu ni module ifite uburebure bwa 1310nm; umuhondo ni module ifite uburebure bwa 1550nm; ibara ry'umuyugubwe ni module ifite uburebure bwa 1490nm.

    Isano ya SFP, SFF na GBIC optique module

    SFP ni impfunyapfunyo ya Ntoya-Ibintu Byoroshye, ni ukuvuga, paki ntoya ya optique module. SFP irashobora gufatwa nkuburyo bworoshye bwa SFF. Imigaragarire yamashanyarazi ni urutoki rwa zahabu 20-pin. Imigaragarire yamakuru yamakuru arasa cyane na module ya SFF. Module ya SFP itanga kandi interineti igenzura I2C, ihujwe na SFP-8472 isanzwe ya optique yo gusuzuma. Byombi SFF na SFP ntabwo bikubiyemo igice cya SerDes, kandi bitanga gusa urutonde rwamakuru. Indishyi zo gukwirakwiza CDR n'amashanyarazi zishyirwa hanze ya module, bigatuma ingano nto hamwe no gukoresha ingufu nke bishoboka. Bitewe no kugabanuka kwubushyuhe, SFF / SFP irashobora gukoreshwa gusa intera ndende-ndende, intera ngufi hamwe nintera yo hagati ya 2.5Gbps na munsi.

    SFP optique module ubu ifite umuvuduko ntarengwa wa 10G, kandi benshi bakoresha interineti ya LC. Birashobora kumvikana gusa nka verisiyo yazamuye GBIC. Ingano ya optique ya SFP yagabanutseho kimwe cya kabiri ugereranije na GBIC optique ya module, kandi inshuro zirenga ebyiri umubare wibyambu urashobora gushyirwaho kumwanya umwe. Kubijyanye nindi mirimo, shingiro rya module ya SFP ni kimwe na GBIC. Kubwibyo, bamwehinduraababikora bita SFP optique modules miniaturized GBIC.
