The yellobrik OBD 1510 E Ethernet to 1Gbit Fiber Bi-directional Transceiver Pair from Lynx Technik AG is a matched pair of compact Ethernet switches designed to extend the reach of electrical Ethernet signals over long distances. The two switches are linked via a single bi-directional fiber link, which operates at a constant 1Gb speed.

This pair of modules uses WDM fiber technology in a closed loop arrangement and essentially functions as an Ethernet extender solution. The fiber link supports distances up to 6.2 mi (10km) and provides a single, high-speed 1Gb error-free optical connection between the two locations.

Each OBD 1510 E module has two standard RJ-45 electrical Ethernet ports and the complete system functions as a 4-port Ethernet switch, providing two standard RJ-45 Ethernet ports at each location bridged with fiber. For legacy systems, each electrical Ethernet port can be set for automatic speed detection (10/100/1000 Mb/s) or forced to 10Mb. Each port uses auto crossover detection or can be forced manually if needed. These functions are available using the dip switch.
