Optical multiplexer ToPGATE-SFP

  • Compact size, no separate power supply
  • Up to 2 structured or unstructured E1 streams transmission through data network without quality deterioration
  • Unique algorithms of frequency recovery which provide stable operation on real networks
  • Advanced monitoring and logging means
  • Management via SNMP, Web, Telnet, SSH
  • Opportunity to transmit separate time slots of E1 streams over Ethernet networks
  • Management restrictions by IP, VLAN, operators actions logging
  • Opportunity to control devices through Eltex-EMS management system
Main features
ToPGATE-SFP multiplexer provides transmission of structured or unstructured E1 streams over packet networks. The device is implemented in SFP form-factor (Small Form Factor Pluggable). The multiplexer is designed for fast and easy connection to standard SFP port of any switch. Compact size and lack of separate power supply allows fast and effective E1 streams output at any point of existing network with minimal time spending on mounting, separate power supply connection and management. Having full function set of the ToPGATE line, ToPGATE-SFP is a cost-effective alternative to separate devices for E1 stream transmission over Ethernet and IP networks on endpoints.
