SWDM Technology for 40G and 100G Ethernet Solutions

This white paper details the implementation of Shortwave Wavelength Division Multiplexing (SWDM) technology as a cost-effective solution for upgrading enterprise data centers to 40G and 100G Ethernet. It outlines the challenges faced by enterprises transitioning from 10G Ethernet, particularly the need to replace existing duplex multimode fiber infrastructure with parallel optics or single mode fiber, both of which present significant capital and operational expenditures. The paper presents SWDM as an alternative that allows the use of existing multimode fiber infrastructure while maintaining familiar LC connectors. It explains how SWDM technology operates using multiple VCSELs at different wavelengths to transmit 40G and 100G Ethernet over standard duplex multimode fiber. The supported reach for SWDM4 transceivers is also discussed, highlighting their compatibility with existing standards and their operational advantages over proprietary solutions. Additionally, the paper emphasizes the multi-vendor approach of the SWDM Alliance to promote interoperability among various vendors' products.
