*Required field


These modules for the High-Density Media Converter System II belong to a large family of modular media converter and communications options for your managed enterprise network. With many modules to choose from, this system can adapt to even the most demanding network configurations.

They convert the incoming electrical signal from one cable type and then transmit it over another type. The media converters are totally transparent to network operation, having no effect on the data being sent across the link. What's more, all of the modules are hot-swappable—you never need to power down a chassis to change a module.

The High-Density Media Converter System II DS3/E3/STS-1 to Duplex Fiber Modules featured here provide conversion from BNC coax cable to duplex fiber for extending DS3, E3, or STS-1 applications. They're ideal in Municipal Area Network (MAN) access applications, for linking buildings over a campus area network, or anywhere incoming coax circuits need to be converted to fiber for distribution. Use fiber to extend high-speed coax circuits at greater distances—as far as 80 kilometers (49.7 mi.) with our single-mode Long modules—and never worry about interference!

The modules are selectable for DS3 (45 Mbps), E3 (34 Mbps), or STS-1 (52 Mbps). Advanced line conditioning and jitter removal features ensure maximum throughput. Fiber loopback and coax loopback test capabilities enable you to troubleshoot remote units from a central location. The modules also feature a transmit data source diagnostic feature and FiberAlert™ for troubleshooting the fiber link.
