Product Overview
The Huawei QSFP28 100G CWDM4 optical transceiver module is designed for high-speed 100G Ethernet applications over single-mode fiber (SMF). Supporting transmission distances up to 2km through duplex LC connectors, this module delivers reliable, low-latency, and high-efficiency optical connectivity for modern data centers, enterprise core networks, cloud computing platforms, and telecom infrastructures.
Utilizing advanced CWDM4 wavelength multiplexing technology, the module integrates four independent optical channels to achieve stable 100Gbps transmission while significantly reducing fiber deployment costs. It complies with IEEE 802.3bm and QSFP28 MSA standards, ensuring broad compatibility with Huawei, Cisco, Juniper, H3C, Arista, and other mainstream networking devices.
The 100G QSFP28 CWDM4 transceiver features low power consumption, hot-pluggable capability, excellent thermal performance, and Digital Optical Monitoring (DOM/DDM) support for real-time operational diagnostics and maintenance.
