The ETU-LINK 10G CWDM SFP+ optical module is a 10G coarse wavelength division multiplexing (CWDM) optical module. It features a hot-swappable SFP+ packaging and a duplex LC optical port, capable of achieving a maximum rate of up to 11.3Gbps. It is typically used in conjunction with single-mode optical fibers. By utilizing CWDM technology, this optical module conserves optical fiber resources, enhancing the flexibility, economy, and reliability of network deployment, while maintaining a very low power consumption. Furthermore, it complies with various standards, including SFP+ MSA, 10G Ethernet, CPRI, Fibre Channel, SONET/SDH, and OTN OTU2e. With an optional wavelength range of 1270nm to 1610nm (with a 20nm spacing), it also incorporates a built-in DDM (Digital Diagnostic Monitoring) function and meets the RoHS environmental protection standard. This optical module finds widespread application in metropolitan area networks (MANs) and 10G Ethernet networks.
