100G QSFP28

Lightx’s 100G QSFP28 transceiver is a compact, industry-standard module designed for high-speed 100 Gigabit Ethernet, data center interconnects, and telecom networks. Utilizing 4x25G NRZ or 4x28G PAM4 modulation, it delivers 100Gbps aggregate bandwidth through parallel fiber channels (e.g., SR4 for multimode or LR4/ER4 for single-mode applications). Built in the QSFP28 form factor, it ensures backward compatibility with QSFP+ ports and supports breakout configurations (4x25G or 2x50G) for flexible integration into legacy systems. Optimized for low power consumption and high-density deployments, it enables cost-effective upgrades in hyperscale data centers, 5G transport, and enterprise core networks. Its robust design and standardized interoperability make it a cornerstone for scalable, future-ready infrastructure, bridging the gap to 400G/800G architectures.
