Lynx Technik yellobrik OET 1544 Ethernet to Fiber Transceiver (switch) - CWDM

The OET 1544 is a compact CWDM-compatible Ethernet 3-port switch designed to extend the reach of electrical Ethernet signals over long distances using a fixed high-speed 1 Gbit/s optical transceiver. It offers 18 selectable CWDM wavelengths, enabling integration into multiplexed CWDM environments. When paired with another OET 1544 at the receiving end (using two fiber links), it provides a cost-effective Ethernet extender system for distances up to 80 km (49.7 miles), ensuring a stable, high-speed, error-free optical connection between locations.
