The model 914-GBE Gigabit Ethernet Media Converter converts 10/100/1000 BASE-T(X) Ethernet from a single RJ-45 to optics, and vice versa, all within a small credit-card size form-factor. The 914-GBE may be used as a standalone card or optically integrated into a 914 system stack via CWDM modules. Optical power budgets are typically 20-24 dB over 10 km of singlemode fiber. Diagnostics are provided by on-board LEDs for power, optical, and data link status. A 12-pin header is also provided to drive LED diagnostics on a front panel or enclosure of a system.



  • Low latency (no switch buffer delays)
  • Compatible with 10/100/1000 Mbps copper links per IEEE 802.3
  • Interchangeable SFP transceivers
  • Rugged design for harsh environment, including 6000 psi pressure tolerant version


  • Provides fast response for time-critical links
  • Backwards compatible with legacy 10/100 Mbps links
  • Supports a wide range of optical options, including CWDM wavelengths for combining multiple cards on a single optical fiber
