Product Description
The Arista QSFP-100G-SWDM4 is a high-density 100 Gigabit Ethernet (100GbE) transceiver that leverages Short Wavelength Division Multiplexing (SWDM4) technology. This innovative approach allows for 100Gb/s transmission over a standard duplex LC connector using multimode fiber (MMF). It operates at an 850nm wavelength, making it compatible with existing MMF infrastructure, and offers a cost-effective solution for upgrading to 100GbE speeds without requiring parallel fiber optics (like MPO/MTP). The SWDM4 standard enables four different wavelengths within the 850nm range to transmit data simultaneously over two fibers (one for transmit, one for receive). This technology significantly simplifies cabling management and reduces costs associated with deploying 100GbE networks. The reach capabilities typically extend up to 70 meters on OM3 multimode fiber and 100 meters on OM4 multimode fiber. Arista Networks designs these transceivers to meet the demanding requirements of modern data centers, cloud providers, and enterprise networks. The QSFP-100G-SWDM4 provides a seamless upgrade path for organizations looking to increase bandwidth density and performance. Its compatibility with standard LC connectors ensures broad interoperability with existing network equipment and cabling plants.
