Eoptolink’s 800G-DR8 Linear-Drive Pluggable Optics (LPO) transceiver is available in OSFP and QSFP112-DD form factors. The 800G-DR8 LPO transceiver supports 800Gbps links up to 500m single-mode fibers. The 800G-DR8 LPO transceiver has eight independent electrical input/output channels at the host interface, operating up to 106.25Gb/s per channel. The 800G-DR8 LPO transceiver only uses linear drivers with gain and equalization control on the TX side and trans-impedance amplifiers (TIA) with output amplitude and equalization control on the RX side. Since the PAM4 DSP (Digital Signal Processor) chip is not used in the 800G-DR8 LPO transceiver, the power consumption of the 800G-DR8 LPO transceiver can be reduced by about 35% compared with existing 800G-DR8 transceivers that use DSP chips.
Judge’s Comment: “An important product that will reduce power dissipation and cost of optical interconnect while maintaining the flexibility of plug-gable transceivers.”
