10/100M Fast Ethernet Media Converter BT31E1F-SM- 20KM series

The BT31E1F-SM- 2KM series are media converter with the DIP Switch. The DIP Switch can set the Link Fault Pass-through (LFP) and Flow-Control function. LFP (LLCF/LLR) can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net. LLCF (Link Loss Carry Forward) means when a device connected to the converter and the TP line loss the link, the converter's fiber will disconnect the link of transmit. LLR (Link Loss Return) means when a device connected to the converter and the fiber line loss the link, the converter's TP port will disconnect the link of transmit. Both can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net.

  • 10/100Mbps auto-sensed, facilitating network upgrade
  • Built-in efficient switching core to implement flow control and reduce broadcast packets
  • Full-duplex and half-duplex auto-sensed
  • Supporting auto-sense of MDI/MDI-X, facilitating system commissioning and installation
  • LFP(Link Fault Pass-through) function
  • Supporting the transmission of 100Base-FX or STM-1, compatible with other devices
  • Supporting low-time lag transmission
  • Supporting the transmission of extra-long packets up to 2048 bytes
  • Extremely low power consumption (less than 2W), reliable and stable performance
  • Options in single mode dual fiber or Multi-mode dual fiber.
