Mangani marudzi e100G optical modules

Iwo zviyero zvine chekuita neindasitiri yekukurukurirana yemaziso anonyanya kubva kumasangano akaita seIEEE, ITU, uye MSA Industry Alliance.Kune akawanda maitiro e100G modules.Vatengi vanogona kusarudza iyo inonyanya kudhura-inoshanda module mhando zvichienderana neakasiyana mashandisirwo mamiriro.Kune mapfupi-kure maapplication mukati me300m, multimode fiber uye VCSEL lasers anonyanya kushandiswa, uye 500m-40km kutapurirana, single-mode fiber, DFB kana EML lasers anonyanya kushandiswa.

Kuenzaniswa ne2.5G, 10G kana 40G wavelength division transmission systems, 100G optical transmission inoshandisa digital coherent receivers kuti iite mepu yose yemaziso emagetsi emagetsi kumagetsi emagetsi kuburikidza nechikamu chakasiyana-siyana uye polarization kusiyana, uye inoshandisa teknolojia yakakura yekugadzirisa zviratidzo mumagetsi emagetsi. .Iyo domain inoshandisa polarization demultiplexing, chiteshi kukanganisa kuenzana muripo, kudzoreredza nguva, fungidziro yechikamu chemutakuri, fungidziro yechiratidzo uye mutsara decoding.Ndichiri kuona 100G optical transmission, ruzhinji rwekuchinja kukuru kwetekinoroji kwakaitika mu100G optical modules, kusanganisira polarization multiplexing phase modulation tekinoroji, digital coherent reception tekinoroji, yechitatu-chizvarwa super kukanganisa kugadzirisa coding tekinoroji, nezvimwewo, nokudaro kugutsa zvinodiwa nevashandisi. uye nguva.Zvido zvinofambira mberi.

1. 100G Optical module

Iwo makuru mapakeji e100G optical modules anonyanya kusanganisira CXP, CFP, CFP2, CFP4, CFP8, uye QSFP28.Nekuvandudzwa mumakore achangopfuura, kutumirwa kweCFP series products kwakaderera zvishoma nezvishoma, uye QSFP28 package yakakunda kukunda kwese nekuda kwehukuru hwayo uye kuderera kwesimba rekushandisa, uye mazhinji ezvichangobva kubuda 200G uye 400G mapakeji anoshandisawo QSFP- DD mapakeji.Parizvino, makambani mazhinji optical module ane 100G akateedzera zvigadzirwa muQSFP28 package pamusika.

1.1 100G QSFP28 optical module

Iyo QSFP28 optical module ine yakafanana dhizaini pfungwa seQSFP optical module.YeQSFP28, chiteshi chega chega chinogona kutumira uye kugamuchira data kusvika ku28Gbps.Kuenzaniswa neCFP4 optical modules, QSFP28 optical modules iduku muhukuru kupfuura CFP4 optical modules.Iyo QSFP28 optical module ine density advantage pamusoro peCFP4 optical module, uye kushandiswa kwesimba panguva yekushanda kazhinji hakupfuuri 3.5W, asi kushandiswa kwesimba kwemamwe ma modules optical kunowanzo pakati pe6W ne24W.Kubva pakuona uku, kushandiswa kwesimba kwakaderera zvikuru kupfuura mamwe 100G optical modules.

1.2 100G CXP optical module

Mwero wekutumira weCXP optical module wakakwira se12 * 10Gbps, uye inotsigira kupisa plugging."C" inomiririra gumi nemaviri muhexadecimal, uye nhamba yeRoma "X" inomiririra kuti chiteshi chega chega chine mwero wekutumira we10Gbps."P" inoreva pluggable inotsigira kupisa kupisa.Iyo CXP optical module inonyanya kunangwa pamusika wekombuta inomhanya, uye ndiyo yekuwedzera yeCFP optical module muEthernet data center.Nehunyanzvi, CFP optical modules inoshandiswa pamwe chete nemultimode optical fibers kupfupi-kure kufambisa data.Nekuti iyo multimode fiber musika inoda yakakwira-density mapaneru, saizi haina kunyatso gadziridzwa kumusika wemultimode fiber.

Iyo CXP optical module ndeye 45mm kureba uye 27mm yakafara, uye idiki pane XFP optical module uye CFP optical module, saka inogona kupa yakakwirira density network interface.Mukuwedzera, iyo CXP optical module imhangura yekubatanidza system inotsanangurwa neWireless Broadband Trade Association, iyo inogona kutsigira 12 10GbE ye10GbE, 3 10G link transmission for 40GbE channels kana 12 10G Ethernet Fiber Channel kana wireless 12 * QDR link transmission ye broadband. zviratidzo.

1.3 100G CFP/CFP2/CFP4 optical module

The CFP Multi-Source Agreement (MSA) inotsanangura zvinodiwa izvo zvinopisa-swappable optical modules zvinogona kushandiswa ku40G uye 100G network transmission, kusanganisira chizvarwa chinotevera high-speed Ethernet (40GbE uye 100GbE).Iyo CFP optical module inotsigira kutapurirana pane imwe-mode uye akawanda-mode mafiber ane akasiyana mazinga, maprotocol uye link kureba, kusanganisira ese e media-dependent (PMD) interfaces inosanganisirwa muIEEE 802.3ba chiyero, uye 100G network ine matatu PMDs: 100GBASE. -SR10 inogona kutumira 100m, 100GBASE-LR4 inogona kutumira 10KM, uye 100GBASE-ER4 inogona kutumira 40KM.

Iyo CFP optical module yakagadzirirwa pahwaro hwediki pluggable optical module (SFP) interface, asi yakakura muhukuru uye inotsigira 100Gbps data transmission.Iyo yemagetsi inoshandiswa neCFP optical module inoshandisa 10 * 10Gbps migero yekutumira kune imwe neimwe nzira (RX, TX), saka inotsigira kutendeuka kwe10 * 10Gbps uye 4 * 25Gbps.Iyo CFP optical module inogona kutsigira imwechete 100G chiratidzo, OTU4, chiratidzo che40G, OTU3 kana STM-256 / OC-768.

Kunyange zvazvo CFP optical module inogona kuona 100G data applications, nekuda kwehukuru hwayo, haigoni kuzadzisa zvinodiwa zve data data data.Muchiitiko ichi, komiti yeCFP-MSA yakatsanangura mamwe maitiro maviri: CFP2 uye CFP4 optical modules.
