Description

The OBD 1514 E 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 single bidirectional fiber link which operates at a constant 1Gbit/s speed.

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

Each OBD 1514 E module has two standard RJ45 electrical Ethernet ports and the complete system functions as a 4 port ethernet switch, providing two standard RJ45 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) or forced to 10Mbit/s. Each port uses auto crossover detection or can be forced manually if needed. These functions are available using the dip switch.

Note: This system uses WDM and should only be used in point to point
applications. WDM cannot be integrated into a CWDM system.

*Distance is an approximation. Actual distances achieved can be longer or shorter depending on the type of cable. Determine link losses and perform optical budget calculations to ensure correct operation.
