Optical multiplexer ToPGATE-16E1-2FG

  • Support for CSFP (Compact Small Form-factor Pluggable) modules. 2 optic-fiber lines can be connected through a single CSFP module
  • Opportunity to view IDProm and DDM (Digital Diagnostics Monitoring) of SFP/CSFP modules
  • DyingGasp
  • Transmission of 16 structured or unstructured E1 streams through data network without quality deterioration
  • Unique algorithms of frequency recovery which provide stable operation on real networks
  • Unified interface with ToPGATE series devices for combination of 100M, 1G and 10G networks based on cooper, optical and wireless technologies
  • Local traffic mirroring
  • MVR (Multicast VLAN Registration) – multicast VLANs registration, which allows to transmit multicast stream in a single VLAN, while end users are capable to obtain it being in different VLANs
  • Support for RSTP protocols for networks with complicated topology with redundancy, e.g. ring with spurs, tree
  • Support for SNMP, Web, Telnet, SSH, RADIUS, TACACS+
  • Local and remote management and diagnosis
  • Opportunity to control devices through Eltex-EMS management system
