Product Overview
The 100G QSFP28 SWDM4 optical transceiver module is designed for high-speed 100 Gigabit Ethernet connectivity over multimode fiber (MMF) networks. Utilizing advanced Shortwave Wavelength Division Multiplexing (SWDM4) technology with operating wavelengths ranging from 850nm to 940nm, this optical module enables stable 100Gbps transmission up to 100 meters over OM4 multimode fiber infrastructure.
Compared with traditional parallel optical solutions, the QSFP28 SWDM4 transceiver significantly improves fiber utilization efficiency by transmitting multiple optical wavelengths through duplex LC multimode fiber. This helps data centers and enterprise networks reduce cabling complexity and infrastructure costs while supporting high-density 100G network deployments.
The module complies with QSFP28 MSA and IEEE Ethernet standards and is fully compatible with mainstream networking equipment from Cisco, Huawei, Juniper, Arista, Mellanox, H3C, and other major brands. Featuring low power consumption, hot-pluggable capability, and Digital Optical Monitoring (DOM/DDM) support, the 100G SWDM4 optical module provides reliable and cost-effective optical interconnect solutions for modern cloud computing and AI networking environments.
