    8-Channel LAN-WDM: A New Benchmark for Low-Dispersion Long-Haul Transmission

    In this era of information explosion, the speed and efficiency of data transmission have become crucial forces driving technological progress. As a pioneer in open optical network components, GIGALIGHT proudly introduces its flagship product – the 8-Channel LAN-WDM optical transceiver. This innovative masterpiece, integrating eight channels into one, is rewriting the future of optical communication at an astonishing pace.

    Why Choose 8-Channel Optics?

    Once regarded as a niche area within the industry due to manufacturing complexities and costs, 8-channel optics is now a milestone in optical technology development and a necessary path to the future. Despite attempts to bypass 8-channel optics through technologies like 100G/200G PAM4, the latter approach may not be as wise in the long run. Optical wavelength division multiplexing (WDM) offers unlimited potential, whereas electrical wavelength division multiplexing is inherently limited. For countries with less advanced semiconductor technologies, prioritizing analog-thinking-led wavelength-division optical technologies is advisable.

    Currently, the mainstream optical transceivers in data centers, be it 100G, 200G, or 400G, primarily adopt a 4-channel architecture, which is also extending into telecommunication networks. Even for 800G, the industry proposes a 4×200G PAM4 design. This trend stems from the ease of design implementation with 4-channel optics combined with DSP. However, GIGALIGHT, an industry design innovator, has taken a different route, developing an extensive product line based on 8-channel optical transceiver architectures, including 8×25G NRZ, 8×50G PAM4, and 8×100G PAM4, from 200G to 400G and now 800G.

    Advantages of 8-Channel LAN-WDM

    1. Low Dispersion: Utilizing LAN-WDM wavelengths, it enables simultaneous data transmission across multiple wavelengths, with each channel operating in a low-dispersion region. This ensures high stability and consistency of optical signals, significantly reducing signal distortion and attenuation caused by dispersion, thereby preserving data integrity and accuracy over long distances. This feature is crucial for enhancing network performance and data transmission quality.
    2. Long-Haul Capability: Integrated with 8-channel cooled EML lasers and photodetectors, GIGALIGHT’s 8-Channel LAN-WDM optical transceivers offer LR8 options for 10km/20km long-haul transmission, ideal for data centers, telecommunication networks, and 5G mid-haul applications.
    3. High Reliability: Featuring GIGALIGHT’s proprietary 8-channel WDM optical engine design, these transceivers boast high manufacturability. Designed with meticulous consideration for the complexity and variability of network environments, they employ high-quality optical components and precise manufacturing processes, ensuring stable operation across various conditions.

    Highlighting Three Star Products

    200G QSFP-DD LR8

    400g-qsfp-dd-lr8

    Based on 8×25G NRZ modulation, the 200G QSFP-DD LR8 achieves a zero bit error rate (BER) of 1E-12 over a transmission distance of 20km. In contrast, industry benchmark products, such as 200G QSFP-DD LR4 with 50G PAM4 modulation, exhibit a BER of 2E-4, a significant difference. For high-reliability 5G mid-haul systems, PAM4 signals might face bandwidth limitations during long-term transmission. The 200G QSFP-DD LR8, however, offers a high-performance, low-latency, and highly reliable channel solution.

    400G QSFP-DD LR8

    400g-qsfp-dd-lr8

    Employing 8×50G PAM4 modulation and a single PCB design, GIGALIGHT’s 400G QSFP-DD LR8 consumes less than 12W of power under various temperature conditions, leading the industry. Compliant with IEEE 802.3bs 400GBASE-LR8 specifications and CMIS 4.0, it boasts exceptional signal integrity and an optoelectronic integration design. Powered by DSP-based 50G PAM4 CDR, it performs superbly, fully satisfying 10km single-mode dual-fiber G.652 transmission applications.

    800G QSFP-DD LR8

    Compatible with GIGALIGHT’s 800G WDM product line, the pre-released 800G QSFP-DD LR8 also utilizes EML lasers and 8×100G PAM4 modulation, supporting 10km transmission distances, ideal for data center and metropolitan area network (MAN) interconnects.

    With superior performance, flexible configuration, and stable transmission capabilities, GIGALIGHT’s 8-Channel LAN-WDM optical transceivers are gradually emerging as stars in the optical communication field. Choosing GIGALIGHT is choosing a future of faster, more efficient, and reliable optical communication!
