Introduction
Thank you for choosing the Metrobility “twister” media converter.
Metrobility “twister” media converters represent the hottest technology available for
extending Ethernet and Fast Ethernet networks. Since Metrobility first developed
“twister” media conversion, it has become a standard for providing a cost-effective
means of integrating a mixed media environment. As LANs grow and evolve, this
technology provides an ideal solution for building effective migration strategies.
These IEEE 802.3u compliant media converters are compatible with Fast Ethernet
devices from other leading network technology providers. This increases the flexibility of your network configuration by ensuring reliable data transmission in multivendor as well as mixed media environments.
The information in this guide will help you to install and start using your “twister”
media converter.
“twister” 2131 Multimode-to-Singlemode Media Converter 5
Overview
The Metrobility “twister” 2131 multimode-to-singlemode (MM-to-SM) media
converters provide seamless high-speed integration of multimode and singlemode
fiber optic segments in Fast Ethernet environments. The “twister” 2131 supports
remote fiber optic links up to 2km over multimode and up to 15km over singlemode
fiber optic cable.
To optimize your Fast Ethernet network, this innovative media converter provides
seamless operation in half-duplex or full-duplex environments. Full signal restoration —with a low bit delay — ensures accurate data transmission to and from LANs
within an organization. All signal activity is completely converted ensuring accurate
communication and collision detection in connected segments and allowing maximum media length to be achieved on either side of the device.
The “twister” 2131 provides the following key feature:
• A Link Loss Carry Forward (LLCF) enable/disable switch to provide an easy
means for troubleshooting a remote network connection. Refer to the section
of this guide titled “Link Loss Carry Forward” for more information.
Whether you are updating or expanding your existing network, the Metrobility line
of “twister” media converters supports a wide range of configuration needs. The
“twister” multimode-to-singlemode media converters include the following media
conversion combinations:
2131-34-01______ FX multimode SC to FX singlemode SC
2131-36-01______ FX multimode SC to FX singlemode ST
2131-54-01______ FX multimode ST to FX singlemode SC
2131-56-01______ FX multimode ST to FX singlemode ST
