Product: NT-2020 Single-/Multi-mode Converter Series
Model: NT-2020 Series
Overview
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.
Features
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
Application
1000Mbps optical Ethernet long-distance transmitting system
