  • Product Description

    The 100G QSFP28 LWDM is a medium-reach optical transceiver module for high-speed data networks, adopting the QSFP28 form factor to deliver 100 Gbps (100GbE) via four parallel 25 Gbps lanes. Operating with LWDM wavelengths over single-mode fiber (SMF) with a Dual LC connector, it supports transmission distances up to 10km. Featuring high density and low power consumption, it is widely used in data center interconnections, metropolitan area networking, and telecommunications transmission scenarios.With advanced optical performance and stable signal transmission, the 100G QSFP28 LWDM helps network operators meet increasing bandwidth demands while maintaining efficient operation. Its compact design enables flexible deployment in high-density environments, reducing rack space requirements and improving network scalability. The module is compatible with various optical networking devices, making it an ideal choice for upgrading existing infrastructure. By combining long-distance transmission capability, energy efficiency, and reliable connectivity, it supports the continuous expansion of cloud computing, 5G networks, and next-generation communication systems.
