Ndi mitundu ingati ya 100G Optical modules

Miyezo yokhudzana ndi makampani olumikizana ndi kuwala makamaka imachokera kumabungwe monga IEEE, ITU, ndi MSA Viwanda Alliance.Pali miyezo ingapo yama module a 100G.Makasitomala amatha kusankha mtundu wa module wotchipa kwambiri malinga ndi zochitika zosiyanasiyana zogwiritsira ntchito.Pogwiritsa ntchito mtunda waufupi mkati mwa 300m, ma multimode fiber ndi ma lasers a VCSEL amagwiritsidwa ntchito kwambiri, ndipo pakutumiza kwa 500m-40km, fiber single-mode, DFB kapena EML lasers amagwiritsidwa ntchito kwambiri.

Poyerekeza ndi 2.5G, 10G kapena 40G wavelength division transmission systems, 100G optical transmission imagwiritsa ntchito zolandirira zamakono kuti zipange mapu onse a kuwala kwa magetsi kudera lamagetsi kupyolera mu kusiyana kwa magawo ndi kusiyana kwa polarization, ndipo amagwiritsa ntchito luso lamakono lopangira ma digito pamagetsi. .Derali limagwiritsa ntchito polarization demultiplexing, chipukuta misozi chofanana ndi njira, kuchira nthawi, kuyerekezera gawo laonyamula, kuyerekezera zizindikiro ndi kumasulira mizere.Pamene mukuzindikira 100G optical transmission, kusintha kwakukulu kwaukadaulo kwachitika mu 100G optical modules, kuphatikizapo polarization multiplexing phase modulation technology, digital coherent reception technology, third-generation super error correction coding technology, etc., motero kukwaniritsa zosowa za ogwiritsa ntchito. ndi nthawi.Zofuna patsogolo.

1. 100G Optical module

Maphukusi akuluakulu a 100G optical modules makamaka akuphatikizapo CXP, CFP, CFP2, CFP4, CFP8, ndi QSFP28.Ndi chitukuko cha m'zaka zaposachedwa, kutumiza kwa CFP mndandanda wazinthu zatsika pang'onopang'ono, ndipo phukusi la QSFP28 lapambana chigonjetso chonse chifukwa cha kukula kwake kochepa komanso kugwiritsa ntchito mphamvu zochepa, ndipo ambiri omwe angoyamba kumene 200G ndi 400G phukusi amagwiritsanso ntchito QSFP- DD phukusi.Pakadali pano, makampani ambiri opanga ma module ali ndi zinthu za 100G mu phukusi la QSFP28 pamsika.

1.1 100G QSFP28 gawo la kuwala

QSFP28 optical module ili ndi lingaliro lofanana la mapangidwe monga QSFP optical module.Kwa QSFP28, njira iliyonse imatha kutumiza ndi kulandira deta mpaka 28Gbps.Poyerekeza ndi CFP4 optical modules, QSFP28 optical modules ndi ang'onoang'ono kukula kuposa CFP4 optical modules.QSFP28 optical module ili ndi kachulukidwe kachulukidwe ka CFP4 optical module, ndipo kugwiritsa ntchito mphamvu panthawi ya ntchito nthawi zambiri sikudutsa 3.5W, pamene mphamvu yogwiritsira ntchito ma modules ena optical imakhala pakati pa 6W ndi 24W.Kuchokera pamalingaliro awa, kugwiritsa ntchito mphamvu kumakhala kotsika kwambiri kuposa ma module ena a 100G optical.

1.2 100G CXP gawo la kuwala

Kutumiza kwa module ya CXP optical ndipamwamba kwambiri mpaka 12 * 10Gbps, ndipo imathandizira plugging yotentha."C" imayimira 12 mu hexadecimal, ndipo nambala yachiroma "X" imayimira kuti njira iliyonse ili ndi mlingo wotumizira wa 10Gbps."P" amatanthauza pulagi yomwe imathandizira mapulagi otentha.The CXP Optical module imayang'ana kwambiri msika wamakompyuta othamanga kwambiri, ndipo ndiwowonjezera wa CFP optical module mu Ethernet data center.Mwaukadaulo, ma CFP optical modules amagwiritsidwa ntchito limodzi ndi ma multimode optical fibers pakutumiza deta mtunda wautali.Chifukwa msika wa multimode fiber umafuna mapanelo olimba kwambiri, kukula kwake sikunakwaniritsidwe kwenikweni pamsika wa fiber multimode.

The CXP optical module ndi 45mm kutalika ndi 27mm m'lifupi, ndipo ndi yaying'ono kusiyana ndi XFP optical module ndi CFP optical module, kotero ikhoza kupereka mawonekedwe apamwamba a network network.Kuonjezera apo, CXP optical module ndi njira yolumikizira yamkuwa yotchulidwa ndi Wireless Broadband Trade Association, yomwe ingathe kuthandizira 12 10GbE kwa 10GbE, 3 10G yotumizira mauthenga a 40GbE kapena 12 10G Ethernet Fiber Channel kapena opanda waya 12 * QDR kutumiza mauthenga a Broadband zizindikiro.

1.3 100G CFP/CFP2/CFP4 optical module

Mgwirizano wa CFP Multi-Source Agreement (MSA) umatanthawuza zofunikira zomwe ma modules otentha otentha amatha kugwiritsidwa ntchito ku 40G ndi 100G kutumiza kwa intaneti, kuphatikizapo Ethernet yothamanga kwambiri (40GbE ndi 100GbE).CFP optical module imathandizira kufalitsa pamtundu umodzi komanso ulusi wamitundu yambiri ndi mitengo yosiyanasiyana, ma protocol ndi kutalika kwa maulalo, kuphatikiza mawonekedwe onse otengera media (PMD) omwe akuphatikizidwa mu IEEE 802.3ba muyezo, ndipo netiweki ya 100G ili ndi ma PMD atatu: 100GBASE -SR10 imatha kutumiza 100m, 100GBASE-LR4 imatha kutumiza 10KM, ndipo 100GBASE-ER4 imatha kutumiza 40KM.

CFP optical module imapangidwa pamaziko a mawonekedwe ang'onoang'ono opangidwa ndi pluggable optical module (SFP), koma ndi yaikulu kukula ndipo imathandizira kutumiza deta ya 100Gbps.Mawonekedwe amagetsi ogwiritsidwa ntchito ndi CFP optical module amagwiritsa ntchito 10 * 10Gbps njira zotumizira mbali iliyonse (RX, TX), kotero imathandizira kutembenuka kwa 10 * 10Gbps ndi 4 * 25Gbps.CFP optical module ikhoza kuthandizira chizindikiro chimodzi cha 100G, OTU4, chizindikiro cha 40G, OTU3 kapena STM-256 / OC-768.

Ngakhale kuti CFP optical module imatha kuzindikira 100G deta yogwiritsira ntchito, chifukwa cha kukula kwake kwakukulu, sikungathe kukwaniritsa zosowa za malo opangira deta.Pankhaniyi, komiti ya CFP-MSA yafotokozera mitundu ina iwiri: CFP2 ndi CFP4 optical modules.
