DWDM (dense wavelength division multiplexing) is the preferred technology in today's optical fiber applications, but the price is relatively expensive. In comparison, CWDM (sparse wavelength division multiplexing) is a low-cost WDM transmission technology for the access layer of man. Now ETU-Link will introduce 10g SFP+ CWDM / DWDM optical module.

10G SFP+ CWDM optical module:

10G SFP+ CWDM optical module is a kind of coarse wavelength division multiplexing optical module, which is usually used with single-mode fiber. This optical module uses CWDM Technology to save optical fiber resources, which can significantly improve the flexibility, economy and reliability of networking, And the power consumption of this optical module is very small, which is 12.5% of 10G SFP+ DWDM optical module.

10G SFP+ DWDM optical module:

10g SFP+ DWDM optical module is a rare high-speed, high-capacity dense wavelength division multiplexing optical module in China. It is usually used together with single-mode optical fiber. The maximum transmission distance is 80km, which is suitable for long-distance data transmission. This optical module can meet the needs of large capacity and long-distance transmission to the greatest extent, providing a stable guarantee for multi service operation and future network upgrading and expansion. It also supports a variety of networking modes and wavelength scheduling among nodes, with the advantages of easy capacity expansion, flexible service access, high bandwidth utilization and high reliability.

10G SFP+ CWDM/DWDM optical module:

10G SFP+ CWDM/DWDM optical module application:

Nowadays, 10G network technology and market are very mature. ETU-Link can provide different wavelength and wavelength simultaneous interpreting wavelength division (CWDM/DWDM) optical modules. The solution of 10G data center is usually 10G switch matched with SFP+ 10G Optical module and LC patch cord. Switches of different speeds should match with optical modules of corresponding speeds.
