SFP Transceiver - ib qho tseem ceeb ua haujlwm hauv 10G Ethernet
Yuav kom ua tau raws li qhov kev txwv tsis pub xaus rau kev ceev tshaj ntawm cov ntaub ntawv xa tawm, Ethernet technology tau pheej hloov txij xyoo 1970 los. 10 Gigabit Ethernet, uas yog ib pawg ntawm kev sib txuas lus hauv computer txuas rau Ethernet thav ntawv ntawm tus nqi ntawm 10 gigabits thib ob (10 × 109 los yog 10 billion khoom rau ib pliag), yuav yog ib qho zoo technology tsim rau cov tuam txhab uas xav xav hloov lawv cov chaw zov me nyuam cov ntaub ntawv kom tau raws li kev tsim cov lag luam tshiab. Txhawm rau xa lub cab rau lub network, tej yam khoom siv yuav tsum tau muab los ua tibzoo. Transceivers muab qhov nruab nrab ntawm cov khoom xa thiab tau txais cov ntaub ntawv thiab cov cabling thauj nws. SFP cov hloov suab npe yog cov ntawm ntau yam khoom siv rau 10 G Ethernet.
Muaj plaub hom kev hloov ntawm cov neeg siv rau 10 G Ethernet-XENPAK, XPAK, XFP thiab SFP +. XENPAK yog thawj 10 G pluggable transceiver nyob rau hauv kev ua lag luam los txhawb kev sib txuas lus 802.3ae standard optics. Tam sim no nws xav hais tias yuav tsum yog overly loj rau kev ceev ntim daim ntawv sau npe. XPAK yog siv hauv Network Interface Card (NIC) thiab Cov Npav Nqus Siab Huv Hla (HBA) kev lag luam rau kev siv hauv Servers thiab NAS. XFP yog qhov tseeb tshaj plaws hauv lub lag luam tawm hauv lub khw. Nws relies rau lub siab ceev interface, siab-muag serializer / deserializer (SERDES) uas yog kim. Yog li XFP ntxiv ib qho tsis tsim nyog rau lub hauv paus system. SFP + transceiver yog siv 10 G optics siv lub Gigabit SFP. Nws muab kev ywj pheej thiab cov nqi kho kom yooj yim rau cov tuam txhab lag luam, cov chaw zov me nyuam, thiab lwm yam. Li no nws yog nrov nta.
SFP Transceiver yog ib tug me me transceiver uas ntsaws rau qhov chaw nres nkoj ntawm SFP ntawm lub voj voog thiab txuas mus rau cov channel thiab Gigabit Ethernet (G) optical fiber cables ntawm lwm kawg. SFP Cov Kev Tshaj Tawm yog siv dav hauv CWDM system thiab DWCM system. DWDM SFP cov kev sib tw tau raws li SFP daim ntawv ceeb toom uas yog tus qauv tsim MSA. Nws muaj ib qho kev ua kom muaj laser uas tawm suab "xim" uas tau txhais hauv DWDM ITU kab sib chaws. Muaj ntau hom SFP kev sib tw rau DWDM system hauv kev ua lag luam. DWDM SFP10G 58.98, uas yog cov DWDM SFP kev sib txuas lus, yog tsim los ua haujlwm hauv DWDM kev sib txuas lus hauv chaw siv xov tooj thiab cov tub ntxhais lub ntsiab. Nrog lub wavelength ntawm 1558.98 nm, nws muaj nyob rau hauv tag nrho cov C-Band Wavelengths ntawm 100GHz.
SFP + Transceivers, uas yog thawj zaug luam tawm rau lub Tsib Hlis 9, 2006, yog cov qauv zoo ntawm SFP transceiver uas txhawb cov ntaub ntawv txog 16 Gbit / s. Lawv muab cov neeg tuaj yeem muaj ntau yam kev sib koom tes. 10G SFP + transceiver tau siv dav rau 10G Ethernet thiab lwm cov kev kub ceev transmissions nrog kev loj hlob sai ntawm fiber ntau optic yees. 10G CWDM SFP + transceiver, piv txwv li, yog ib qho qauv me me ntawm cov khoom siv pluggable rau kev sib txuas ntawm cov ntaub ntawv sib txuas lus xws li IEEE 802.3ae 10GBASE-LR / LW / ER / ZR. Nws tuaj yeem siv nrog ib tus kabmob CWDM lossis ib lub tshuab fiber ntau CWDM. Cisco DWDM SFP + transceiver yog lwm hom SFP + transceiver uas tsim los ntawm Cisco. Kev txhawb nqa 10-Gigabit cov ntaub ntawv los ntawm 9.9G rau 11.1G kom haum raws li cov kev siv sib txawv, Cisco DWDM SFP + transceiver pub rau cov chaw lag luam thiab cov chaw muab kev pab cuam kom muab kev lag luam thiab siv yooj yim-10-Gbps LAN, WAN, thiab optical thauj network (OTN) kev pab hauv lawv tes hauj lwm.
10 G muaj peev xwm ua tau rau cov txiaj ntsig zoo tam sim thiab tiv thaiv ib lub tuam txhab kev lag luam zoo rau yav tom ntej. Los ua kom siv tag nrho 10 G Ethernet, SFP transceiver plays lub luag haujlwm tseem ceeb hauv kev txuas lub cabling mus rau lub network. FOCC manufactures thiab khoom siv ntau yam ntawm optical transceiver modules uas tau customized, nrog rau cov 10g CWDM SFP +, Cisco DWDM SFP + thiab DWDM SFP10G 58.98.
