10G CWDM SFP+ module uses CWDM technology to save fiber resources, which can significantly improve the flexibility, economy, and reliability of networking, and the power consumption of this optical module is very low. The 10G CWDM SFP+ optical module solution can simultaneously transmit up to 18 wavelengths on a single optical fiber, and fully complies with SFP+MSA SFF+and IEEE 802.3ae protocol specifications and requirements. It enables enterprises and service providers to increase the capacity of their existing 10 Gb Ethernet fiber infrastructure without installing new fiber bundles.
