    GIGALIGHT Launches Industrial-Grade 50G SFP56 PAM4 Portfolio for 5G Fronthaul
    Shenzhen, China, Nov 30, 2022 – After several months of rigorous client testing and trials, GIGALIGHT has successfully developed a full range of industrial-grade 50G SFP56 PAM4 optical modules and plans to put them into production.
    Compared with the 25G SFP28 optical module currently used in 5G fronthaul, the 50G SFP56 optical module has the same package size, but the rate is increased to 50Gb/s, so it can save 50% of the ports, thereby further improving the density and bandwidth of 5G fronthaul, helping the 5G fronthaul network of O-RAN and vRAN architecture smoothly evolve to the next generation.
    For most industry manufacturers, the 50G SFP56 PAM4 optical module adopts the traditional SFP package, which has great difficulties in terms of power consumption, heat treatment and high-density design of hardware. However, GIGALIGHT has overcome many difficulties, completed the established design tasks in terms of software and hardware, and launched a series of rich 50G SFP56 PAM4 optical modules.

    GIGALIGHT Launches a Series of 400G Long-Reach 8-lane Transceivers to Provide Metro Telecom and DCI within 40km a Definite Solution
    Shenzhen, China, Nov 23, 2022 – As an 8-lane optics advocate, GIGALIGHT launches a series of new products to boost its market application. The company believes that this family of products will inject long-term reliability into metro telecom transport network and metro DCI network with its high performance and low latency.
    From 200G to 800G, GIGALIGHT insisted on taking a different approach, focusing on the development of 8-lane optics architecture based on 25G NRZ, 50G PAM4 and 100G PAM4, and formed a rich product line.
    The newly launched 400G long-reach 8-lane optical transceivers adopt the optoelectronic integrated design based on 50G PAM4 DSP to ensure excellent signal integrity and performance. These modules support both 400G Ethernet and OTN, suitable for data center and telecommunications networks.
