GVM-1220 Version: 1
RJ45 to SC Managed Gigabit Media Converter,
Single-Mode Fiber, 20km
GVM-1220 series is remote Managed Gigabit Ethernet fiber media converter with OAM functions
developed by our company. It can convert Ethernet signal between 10/100/1000Base-T and 1000Base-X, It
supports both half-duplex and full-duplex operations and a variety of fiber options. It is double fiber, single
mode, 20km media converter
Remote devices can be managed by fiber-connected OAM media converter or OAM switch when deployed
as a stand-alone solution. It incorporates an easy to use Web user interface for operation, administration
and maintenance, both locally and remotely. By offering IEEE802.3ah OAM compliance, this converter can
be linked to any IEEE802.3ah compliant fiber switch and support loop back and dying gasp functions. All
functions of this converter and the remotely connected converter can be configured and monitored via Web
management, including bandwidth control, duplex, speed and VLAN configuration.
