Qhov no transceiver yog ib qho kev ua tau zoo module rau luv luv-ntu duplex cov ntaub ntawv kev sib txuas lus thiab interconnect daim ntaub ntawv. Nws koom ua ke plaub txoj kab hluav taws xob cov ntaub ntawv nyob rau hauv txhua qhov kev taw qhia rau hauv kev sib kis ntawm ib leeg LC duplex fiber ntau optic cable. Txhua txoj kab hluav taws xob ua haujlwm ntawm 10.3125 Gbps thiab ua raws li 40GE XLPPI interface. Lub transceiver sab hauv multiplexes XLPPI 4x10G interface rau hauv ob lub 20Gb / s hluav taws xob raws, xa thiab tau txais txhua qhov optically dhau ib qho yooj yim LC fiber ntau siv ob-directional optics. Qhov no ua rau muaj kev sib sau bandwidth ntawm 40Gbps rau hauv duplex LC cable. Qhov no tso cai rov qab siv lub LC duplex cabling infrastructure rau 40GbE daim ntawv thov. Txuas txuas mus txog 100 m siv OM3 thiab 150m siv OM4 optical fiber tau txais kev txhawb nqa. Cov qauv no tau kos npe los ua haujlwm dhau los ntawm ntau hom fiber ntau siv lub nominal wavelength ntawm 850nm ntawm ib kawg thiab 900nm ntawm qhov kawg. Cov hluav taws xob sib txuas siv 38 tiv tauj QSFP + hom ntug txuas. Lub optical interface siv cov pa LC duplex connector. Transceiver Block Diagram • Tsis Txaus Siab Qhov Ntsuas Parameter Cim Min.
