Product: NT-2020 Single-/Multi-mode Converter Series 

Model: NT-2020 Series 


The NT-2020 series single-/multi-mode converters are applied in 1000Mbps fast Ethernet Network, which is wired with both single mode fibers and multi-mode fibers. It can not only fulfill the conversion of single mode and multi mode at 1310nm wavelength, but also that of 850nm/1310nm and 1550nm wavelengths, which functions as a relay and then makes multi-mode fibers transmit farther. It supports transmission in multi-mode dual fiber, single mode dual fiber and single mode single fiber.


  • Supporting IEEE802.3z 1000Base-SX/LX standards
  • Supporting full-duplex/half-duplex
  • Supporting conversion between 850nm multi-mode fibers and 1310nm/1550nm single mode fibers
  • Supporting direct and transparent transmission of packets at different lengths
  • Supporting the transmission of extra-long VLAN packets
  • Supporting Quality of Service (QoS) and ensuring the transmission of VoIP packets;
  • Supporting STP to form a redundant network;
  • Low power consumption, low heat, reliable and stable performance, and long lifetime;
  • Options in single mode in dual fiber, multi-mode in dual fiber, and single mode in single fiber
