FETURES

• DWDM transmission
  The WDM-CASTER can be established the thirty two channels bi-directional Wavelength Division Multiplex (WDM) transmission networks with an optical fiber pair.
• Production for video, audio and Ethernet
  CU-173 is the WDM-CASTER unit which multiplex video, audio and Giga Ethernet to one wavelength for WDM transmission system.
• High optical sensitivity for long distance transmission
  The minimum receiving sensitivity of each unit is -25 dBm which will be established for long distance transmission. And optical amplifier unit CU-542 presents to design and to establish the very long distance wide aria network very easily.
• Suitable for every network topology
  The WDM CASTER is suitable for every network topology, that are Point to point, Ring and AWG-STAR. AWG-STAR is a full mesh optical network with star-type optical fiber connections.
• Hot swap available management unit
  All the interface units and the double power supply units are supported hot swap functions for easy and quick maintenance. The SNMP can manage the network.
