Product Highlights
1. 100G CWDM4 Mid-Reach Transmission This is a 100GBASE-CWDM4 QSFP28 transceiver designed for data center and enterprise applications. It delivers 100Gbps full-duplex transmission over standard G.652 single-mode fiber (SMF) using a 4-channel CWDM architecture, with wavelengths in the 13xx nm band. The module supports a maximum reach of 2km, making it ideal for leaf-spine architectures and short-range data center interconnects. 2. Standard QSFP28 Form Factor & Features It uses the industry-standard QSFP28 (Quad Small Form-factor Pluggable 28) package, widely adopted in high-density 100G switches and routers. Built-in Digital Optical Monitoring (DOM) allows real-time monitoring of key parameters including TX/RX optical power, module temperature, supply voltage, and laser bias current. The hot-pluggable design allows for easy installation, replacement, and capacity expansion without disrupting network operations. 3. Reliable Performance & Compliance Certified as a Class 1 Laser product under 21CFR1040.10 standards, and compliant with CE safety regulations. Manufactured in China, it undergoes rigorous factory testing to ensure stable performance in the commercial temperature range.
