QSFP-100G-SWDM4 Arista 100GBASE-SWDM4 QSFP Transceiver OM3/OM4 Fiber

The Arista QSFP-100G-SWDM4 transceiver enables 100 Gigabit Ethernet connections using SWDM4 technology, which sends multiple wavelengths over a single multi-mode fiber. This module is often found in data centers and enterprise networks where high-speed, short-range communication is essential.

Built for environments requiring reliable and efficient connectivity, it caters to network engineers and IT professionals looking to maximize fiber infrastructure without sacrificing speed. Its compact QSFP form makes it a straightforward choice for modern switches and routers.

Key Features

• Delivers 100Gbps data rates via four wavelengths on duplex multi-mode fiber
• Compatible with OM3 fibers up to 70 meters and OM4 fibers up to 100 meters
• Plug-and-play QSFP module simplifies deployment and maintenance
• Improves fiber utilization by using SWDM4 technology instead of multiple fibers
• Supports low power consumption suitable for dense networking environments

This transceiver is typically deployed in data centers aiming to upgrade to higher speeds without extensive fiber rewiring. It fits well in setups connecting servers, switches, or storage systems where space and fiber count reduction matter. Its real-world benefits include cost-efficient scaling and easier network upgrades while maintaining high performance.
