TheQSFP+ ma transceiver modules adapangidwa kuti azigwiritsidwa ntchito mu 40 Gigabit pa sekondi imodzi pama fiber multimode.Amagwirizana ndi QSFP + MSA ndi IEEE 802.3ba 40GBASE-SR4. Gawo la optical transmitter la transceiver limaphatikizapo 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) gulu, 4-channel input input buffer ndi laser driver, control and bias. midadada.Gawo lolandila kuwala la transceiver limaphatikizapo 4-channel PIN photodiode array, 4-channel TIA array, 4 channel output buffer, control blocks.
