Antaira FCU-100W Fast Ethernet to WDM A/B Fiber Media Converter

Media converters form the final link that gives your fiber network its true capacity. For the most complicated designs, standardizing your converters improves reliability and expectations. For simpler systems, customizing your converter(s) to exact needs can often save considerable money. For either case, Antaira Technologies has the FCU-100W. Impressively low in cost, this single Fast Ethernet converter is available for virtually any WDM configuration you could need.

Choose from WDM-A or WDM-B signals to attach to multi-mode or single-mode fiber lines that range from 2 km to 80 km. Once fitted to your design, you can use this converter to employ traditional Ethernet devices in industrial work that ranges from Wi-Fi access to pipeline monitoring. You can trust that your devices will have the broadband access they need with absolutely minimal downtime.

Redundant features make it easy for your IT team to keep this converter hard at work. Link alarm support actively monitors connections while LED indicators provide single-glance analysis that add speed to deployment and diagnostics. Secure mounting options make sure the compact design isn’t susceptible to heavy vibrations, and the 5-year warranty supports using this device in the most demanding environments.
