    Nhazi na ule nke 400G modul anya

    Oge nzipu: Ọgọst-24-2019

    Modul ngwa anya bụ isi akụrụngwa akụrụngwa iji ghọta njikọ netwọkụ anya na etiti data. Site na mmụba nke ọnụ ọgụgụ ọdụ ụgbọ mmiri na njupụta, ọnụahịa nke modul ngwa anya ga-aza ihe fọrọ nke nta ka ọ bụrụ ọkara nke ọnụ ahịa netwọk anya na data center. Ka ọ dị ugbu a, 100G interconnection technology ejiriwo ọtụtụ ebe na ebe data e wuru ọhụrụ nke nnukwu ụlọ ọrụ Ịntanetị, na teknụzụ njikọ njikọ 400G ga-ejikarị na-esote afọ 1-2. Ya mere, teknụzụ mmejuputa nke 400G optical modul aghọwo ihe na-elekwasị anya nke ụlọ ọrụ ahụ.

    N'ihe gbasara ogologo ebili mmiri ọkụ, 400G modul ọkụ nwere ike kewaa n'ime multi-mode (MM) na otu-mode (SM) .N'ihe gbasara ọnọdụ mgbanwe mgbaàmà, enwere ike kewaa ya na NRZ na PAM4 modulation (PAM4 bụ isi. ugbu a) .N'ihe gbasara nnyefe nnyefe, 400G modul optical nwere ike kewaa n'ime SR, DR, FR na LR. Site na ụdị nkwakọ ngwaahịa, 400G optical module nwere ike kewaa CDFP, CFP8, OSFP, qsfp-dd na ndị ọzọ. N'okpuru ebe a bụ nhazi teknụzụ nke modul ngwa anya 400G.

    Modul ngwa anya 400G nke mbụ jiri 16-channel 25Gbps NRZ mmejuputa (dị ka 400g-sr16), na-eji CDFP ma ọ bụ CFP8 ngwugwu. Uru nke NRZ bụ na enwere ike ịgbaziri ya site na teknụzụ 25G NRZ tozuru oke na modul ngwa anya 100G, mana ọghọm ya bụ na ọ chọrọ ọwa akara ngosi 16 maka nnyefe yiri ya, yana oke oriri na olu, nke na-adabaghị maka ngwa nke data center.

    Na nke ugbu a 400G ngwa anya modul, 8-channel 53GbpsPAM4 (400g-sr8,FR8,LR8) ma ọ bụ 4-channel 106GbpsPAM4 (400g-dr4, FR4, LR4) na-tumadi iji nweta 400G mgbaàmà nnyefe n'akụkụ anya ọdụ ụgbọ mmiri, na 8. A na-eji akara ọkụ eletrik 53GbpsPAM4 chanel n'akụkụ ọdụ ụgbọ mmiri eletrik, na-ewere ụdị nkwakọ ngwaahịa OSFP ma ọ bụ qsfp-dd. Ma ngwugwu OSFP na QSFP-DD na-enye 8 - ọwa eletrik eletrik interfaces. N'iji ya tụnyere, nha ngwugwu qsfp-dd dị ntakịrị (dị ka 100G optical module QSFP28 ngwugwu), nke dabara adaba maka ngwa data center. Ogo ngwungwu OSFP dị ntakịrị ibu, n'ihi na ọ nwere ike inyekwu oriri ike, yabụ dabara adaba maka ngwa nkwukọrịta.

    Ọnụ ọgụgụ na-esonụ na-egosi mmejuputa 400g-fr8 /LR8 na 400g-fr4 n'otu n'otu.

    (Ntụaka:Nkọwa OSFPMSA maka OSFP OCTAL SMALLFORM FACTOR PUGGABLE MODULE.)Enwere ike ịhụ na akụkụ interface bụ 8-channel 53Gbps PAM4. Maka 400g-sr8 / FR8 / LR8 na modul ndị ọzọ,

    CDR (mweghachi elekere) na ntughari eletrọnịkị / ngwa anya ma ọ bụ anya / eletrik ka a na-eme naanị n'ime modul ngwa anya. Ya mere, akụkụ ọdụ ụgbọ mmiri anya bụkwa akara ngosi 8-ọwa 53Gbps PAM4, dị ka nha ọdụ ụgbọ mmiri eletrik. Maka 400g-dr4 / FR4 / LR4 na modul ndị ọzọ, e nwere Gearbox ibe n'ime modul ngwa anya nke na-ebuwanye ntinye nke abụọ ahụ. ọdụ ụgbọ mmiri n'ime otu mgbaàmà ma gbanwee ya na ìhè, ya mere ọsọ nke ọdụ ụgbọ mmiri anya bụ okpukpu abụọ nke ọdụ ụgbọ mmiri, ya bụ, 106GbpsPAM4 mgbaàmà.
