40KM 40G QSFP+ Optical Transceiver Module
TheHUAQ40Endi module ya transceiver yopangidwira ntchito zolumikizirana zamagetsi za 40Km. Kapangidwe kake kakugwirizana ndi 40GBASE-ER4 ya muyezo wa IEEE P802.3ba. Module iyi imasintha njira 4 zolowera (ch) za data yamagetsi ya 10Gb/s kukhala zizindikiro 4 za CWDM, ndikuzichulukitsa kukhala njira imodzi yotumizira magetsi ya 40Gb/s. Mosiyana ndi zimenezi, kumbali ya wolandila, module iyi imachotsa ma multiplexes a 40Gb/s mu zizindikiro 4 za CWDM, ndikuzisintha kukhala deta yamagetsi yotulutsa ma channel 4.
Mafunde apakati a njira zinayi za CWDM ndi 1271, 1291, 1311 ndi 1331 nm monga ziwalo za gridi ya mafunde a CWDM yomwe yafotokozedwa mu ITU-T G694.2. Ili ndi cholumikizira cha LC cha duplex cha mawonekedwe a kuwala ndi cholumikizira cha ma pin 38 cha mawonekedwe amagetsi. Kuti muchepetse kufalikira kwa kuwala mu dongosolo la kutalika, ulusi wa single-mode (SMF) uyenera kugwiritsidwa ntchito mu gawoli.
Chogulitsachi chapangidwa ndi mawonekedwe, kulumikizana kwa kuwala/magetsi komanso mawonekedwe owunikira digito malinga ndi QSFP Multi-Source Agreement (MSA). Chapangidwa kuti chikwaniritse zovuta kwambiri zakunja monga kutentha, chinyezi ndi kusokoneza kwa EMI.
Moduleyi imagwira ntchito kuchokera ku mphamvu imodzi ya +3.3V ndipo ma siginecha olamulira padziko lonse lapansi a LVCMOS/LVTTL monga Module Present, Reset, Interrupt ndi Low Power Mode amapezeka ndi ma module. Pali mawonekedwe awiri olumikizirana omwe angagwiritsidwe ntchito kutumiza ndi kulandira ma siginecha ovuta kwambiri komanso kupeza zambiri zokhudzana ndi matenda a digito. Ma channels amodzi ndi amodzi amatha kulumikizidwa ndipo ma channel osagwiritsidwa ntchito amatha kutsekedwa kuti pakhale kusinthasintha kwakukulu pakupanga.
Chogulitsachi chimasintha deta yamagetsi ya 10Gb/s ya njira 4 kukhala zizindikiro za CWDM (kuwala), pogwiritsa ntchito makina a Distributed Feedback Laser (DFB) oyendetsedwa ndi mafunde 4. Kuwalako kumaphatikizidwa ndi zigawo za MUX ngati deta ya 40Gb/s, ndikufalikira kuchokera ku module yotumizira kuchokera ku SMF. Module yolandila imalandira kulowetsedwa kwa zizindikiro za CWDM za 40Gb/s, ndikuzichotsa mu njira zinayi za 10Gb/s zokhala ndi mafunde osiyanasiyana. Kuwala kulikonse kwa mafunde kumasonkhanitsidwa ndi diode ya discrete avalanche (APD), kenako nkutulutsidwa ngati deta yamagetsi pambuyo powonjezeredwa koyamba ndi TIA kenako ndi post amplifier.
TheHUAQ40EYapangidwa ndi mawonekedwe, kulumikizana kwa kuwala/magetsi komanso mawonekedwe owunikira digito malinga ndi QSFP Multi-Source Agreement (MSA). Yapangidwa kuti ikwaniritse zovuta kwambiri pakugwira ntchito kwakunja kuphatikizapo kutentha, chinyezi ndi kusokonezeka kwa EMI. Module iyi imapereka magwiridwe antchito apamwamba kwambiri komanso kuphatikiza mawonekedwe, komwe kumapezeka kudzera pa mawonekedwe awiri otsatizana.
Mawonekedwe Mapangidwe a njira 4 za CWDM MUX/DEMUX Mpaka 11.2Gbps pa bandwidth ya njira iliyonse Bandwidth yokwanira ya > 40Gbps Cholumikizira cha LC cha Duplex Kugwirizana ndi 40G Ethernet IEEE802.3ba ndi 40GBASE-ER4 Standard Kutsatira malamulo a QSFP MSA Kutumiza kwa magalimoto mpaka 40km Kugwirizana ndi mitengo ya data ya QDR/DDR Infiniband Mphamvu yamagetsi imodzi +3.3V ikugwira ntchito Ntchito zowunikira za digito zomwe zamangidwa mkati Kutentha kwapakati pa 0°C mpaka 70°C Kutsatira RoHS
Kuwala Makhalidwe (T)OP = 0 mpaka 70°C, VCC = 3.135 mpaka 3.465 Ma Volti) -21.2 0.5
