Mawonekedwe: ◊ Kugwirizana ndi 40GbE XLPPI mafotokozedwe amagetsi pa IEEE 802.3ba-2010 ◊ Kugwirizana ndi QSFP+ SFF-8436 Specification ◊ Aggregate bandwidth > 40Gbps ◊ Imagwira pa 10.3125 data yamagetsi perncod6 Gb6 Gb ◊ QSFP MSA imagwirizana ◊ Yotha kutumiza kupitilira 100m pa OM3 Multimode Fiber (MMF)ndi 150m pa OM4 MMF ◊ Mphamvu yamagetsi Imodzi +3.3V ikugwira ntchito ◊ Popanda ntchito zowunikira digito ◊ Kutentha kosiyanasiyana 0 °C mpaka 70 °C Gawo ◊ RoHS ◊ Amagwiritsa ntchito LC yokhazikika Chingwe cha duplex chololeza kugwiritsanso ntchito zida zomwe zilipo kale Mapulogalamu: ◊ 40 Gigabit Ethernet zolumikizira ◊ Kusintha kwa Datacom/Telecom & kulumikizana kwa rauta ◊ Kuphatikizira kwa data ndi kugwiritsa ntchito ndege zam'mbuyo Fiber-Optic QSFP+ Transceiver ya 40 Gigabit Ethernet Mapulogalamu. Transceiver iyi ndi gawo lochita bwino kwambiri lolumikizana ndi data lachidule la duplex komanso kugwiritsa ntchito kulumikizana. Imaphatikizira mayendedwe anayi amagetsi amagetsi mbali iliyonse kupita kumayendedwe kudzera pa chingwe chimodzi cha LC duplex fiber optic. Njira iliyonse yamagetsi imagwira ntchito pa 10.3125 Gbps ndipo imagwirizana ndi mawonekedwe a 40GE XLPPI. Transceiver mkati mwake imachulukitsa mawonekedwe a XLPPI 4x10G m'njira ziwiri zamagetsi za 20Gb / s, kutumiza ndi kulandira aliyense optically pa simplex LC fiber pogwiritsa ntchito bi-directional optics. Izi zimabweretsa bandwidth ya 40Gbps kukhala chingwe cha duplex LC. Izi zimalola kugwiritsanso ntchito zida zoyika za LC duplex cabling za 40GbE application. Lumikizani mtunda mpaka 100m pogwiritsa ntchito OM3 ndi 150m pogwiritsa ntchito OM4 optical fiber imathandizidwa. Ma modulewa adapangidwa kuti azigwira ntchito pamakina opangira ma multimode fiber pogwiritsa ntchito mawonekedwe amtundu wa 850nm mbali imodzi ndi 900nm mbali inayo. Mawonekedwe amagetsi amagwiritsa ntchito cholumikizira chamtundu wa 38 QSFP +. Mawonekedwe owoneka amagwiritsa ntchito cholumikizira wamba cha LC duplex.
