The FiberMania 100G QSFP28 CWDM4 Transceiver is a high-performance, long-reach optical module engineered for modern data center interconnects (DCI), enterprise backbones, and metro networks. Using coarse wavelength-division multiplexing (CWDM) technology, it transmits data over four parallel 25Gbps lanes, delivering an aggregate 100Gbps bandwidth over single-mode fiber for distances up to 10 kilometers. This compact QSFP28 module reduces cabling complexity while providing reliable high-speed connectivity.

Equipped with a duplex LC connector interface and integrated Digital Diagnostic Monitoring (DDM), the transceiver enables real-time monitoring of optical power, temperature, and voltage. Its hot-pluggable design, low power consumption (<3.5W), and energy-efficient operation make it an ideal solution for 100G Ethernet uplinks, cloud infrastructure, and high-density networking applications.

Fully compliant with QSFP28 MSA, IEEE 802.3bm, and 100G CWDM4 optical standards, this module offers plug-and-play deployment and seamless interoperability with multi-vendor network equipment, ensuring a scalable and cost-effective optical solution.
