    Ihe omuma nke modul Optical

    Oge nzipu: Ọktoba 23-2019

    Nke mbụ, ihe ọmụma bụ isi nke modul anya
    1.Nkọwa:
    Modul anya: ya bụ, modul transceiver anya.
    2.Nhazi:
    Modul transceiver optical bụ nke ngwaọrụ optoelectronic, sekit na-arụ ọrụ na interface anya, na ngwaọrụ optoelectronic gụnyere akụkụ abụọ: nnyefe na ịnata.

    Akụkụ na-ebufe bụ: mgbama ọkụ eletrik na-etinye ụfọdụ ọnụọgụ koodu ka a na-ahazi ya site na mgbawa ịnya ụgbọ ala iji kwọọ semiconductor laser (LD) ma ọ bụ ọkụ na-emitting diode (LED) iji wepụta akara ọkụ gbanwere nke ọnụego kwekọrọ, yana ngwa anya. ike akpaka akara sekit bụ esịtidem nyere n'ime ya. Ike mgbama ngwa anya na-arụpụta ihe ka kwụsiri ike.

    Akụkụ na-anata bụ: modul ntinye mgbama ngwa anya nke ụfọdụ ọnụọgụ koodu ka agbanwere ka ọ bụrụ akara eletrik site na diode fotodetecting. Mgbe preamplifier ahụ gasịrị, a na-emepụta akara ọkụ eletrik nke ọnụọgụ koodu kwekọrọ, na mgbama mmepụta bụ ọkwa PECL n'ozuzu. N'otu oge ahụ, mgbaama mkpu na-apụta mgbe ike ngwa anya ntinye erughị otu uru.

    3.the parameters na mkpa nke ngwa anya modul

    Modul anya nwere ọtụtụ paramita teknụzụ optoelectronic dị mkpa. Agbanyeghị, maka modul ngwa anya abụọ na-ekpo ọkụ, GBIC na SFP, paramita atọ ndị a kacha echegbu mgbe ị na-ahọrọ:

    (1) Ogologo ikuku etiti

    Na nanometers (nm), enwere ụdị isi atọ ugbu a:

    850nm (MM, multimode, ọnụ ala dị ala mana anya nnyefe dị mkpụmkpụ, n'ozuzu naanị 500M); 1310nm (SM, otu ọnọdụ, nnukwu ọnwụ n'oge nnyefe ma obere mgbasa, nke a na-ejikarị maka nnyefe n'ime 40KM);

    1550nm (SM, otu ọnọdụ, obere ọnwụ n'oge nnyefe mana nnukwu mgbasa ozi, nke a na-ejikarị eme ihe maka nnyefe dị anya n'elu 40KM, ma nwee ike ibunye 120KM ozugbo na-enweghị ntụgharị);

    (2) Ọnụego nnyefe

    Ọnụọgụ nke bits (bits) nke data ekesara kwa sekọnd, na bps.

    Enwere ụdị anọ a na-ejikarị: 155 Mbps, 1.25 Gbps, 2.5 Gbps, 10 Gbps, na ihe ndị yiri ya. Ọnụego nnyefe na-adakọkarị azụ azụ. Ya mere, a na-akpọ 155M ngwa anya modul FE (100 Mbps) ngwa anya modul, na 1.25G modul anya na-akpọkwa GE (Gigabit) modul anya.

    Nke a bụ modul kacha eji eme ihe na ngwa nnyefe anya. Na mgbakwunye, ọnụego nnyefe ya na sistemụ nchekwa fiber (SAN) bụ 2Gbps, 4Gbps na 8Gbps.

    (3) Ogologo nnyefe

    Ọ dịghị mkpa ka ebufe akara ngosi anya n'ebe dị anya nke enwere ike ibunye ya ozugbo, na kilomita (nke a na-akpọkwa kilomita, km). Modul anya n'ozuzu nwere nkọwa ndị a: multimode 550m, otu ọnọdụ 15km, 40km, 80km, na 120km, na ndị ọzọ.
