How much does a 40km optical module cost

40km optical modules range from approximately €508 for 100G QSFP28 modules to factory-priced 1G CWDM SFP modules, depending on speed and type.

Pricing Examples

• 100G QSFP28 40km Module: EdgeOptic lists the 100G-4WDM-QSFP40KM compatible module at €508, designed for 100GBASE-4WDM-40 applications over single-mode fiber with LC connectors and host RS-FEC support for full 40 km reach .
• 1.25G CWDM SFP 40km Module: Optcore offers a 1G CWDM SFP EX transceiver module for 40 km transmission over single-mode fiber. This module supports 1270–1610 nm wavelengths, LC duplex connectors, and digital diagnostic monitoring. Pricing is factory-level and cost-effective, typically lower than high-speed 40G or 100G modules .
• 40G QSFP+ Modules: FS provides a range of 40G QSFP+ optical transceivers with distances up to 80 km. Prices vary depending on vendor, model, and features such as DOM (Digital Optical Monitoring) and wavelength, but 40 km modules are generally mid-range in cost compared to shorter or longer reach modules .

Key Considerations

• Data Rate: Modules are available in 1G, 40G, and 100G speeds. Higher-speed modules (40G/100G) are more expensive than 1G modules.
• Connector Type: Most 40 km modules use LC duplex connectors for single-mode fiber.
• Wavelength: CWDM modules cover 1270–1610 nm, while LAN-WDM modules for 100G use multiple channels around 1295–1310 nm.
• Compatibility: Ensure the module matches your switch or router platform (e.g., Extreme Networks, Cisco, or generic QSFP28).
• Warranty and Support: Many vendors offer lifetime or multi-year warranties, which can affect pricing.

Summary

For a 40 km optical module, prices typically range from affordable 1G CWDM SFP modules to €500+ for 100G QSFP28 modules. The exact cost depends on speed, vendor, and features. For bulk purchases or specific vendor compatibility, contacting suppliers like FS, Optcore, EdgeOptic, or Alibaba distributors is recommended to obtain a precise quote .
