Price of a 20km optical module

20km optical modules typically range from around €12 for 10G SFP+ modules to higher prices depending on brand and specifications.

For example, EdgeOptic offers a 10G-SFP-20 20km SFP+ transceiver starting at €12, supporting 10 Gigabit Ethernet over single-mode fiber at 1310nm with LC duplex connectors and DDM diagnostics . These modules are hot-pluggable, multi-vendor compatible, and suitable for campus or inter-site links up to 20km. Other options include 1.25G SFP 20km modules for Gigabit Ethernet, which are widely used in enterprise networks and typically have similar single-mode 1310nm operation with LC duplex connectors and built-in DDM . Prices for these 1G modules are generally in the same low-cost range but can vary depending on manufacturer and vendor. High-performance 10G CWDM SFP+ modules for 20km links, such as Optcore's OPC10G-xx20DCR, may cost more due to additional features like multiple CWDM wavelengths and enhanced digital diagnostic monitoring . Key factors affecting price include:

• Data rate (1G vs 10G)
• Brand and vendor
• Additional features like CWDM support or enhanced diagnostics
• Warranty and support options In summary, a standard 20km SFP or SFP+ optical module can start from approximately €12, with higher-end or specialized modules costing more depending on features and vendor .
