CNGE20FX4TX16MS
All Gigabit Managed Ethernet Switch
with (16) 10/100/1000TX + (4) 100/1000FX SFP Ports
The ComNet CNGE20FX4TX16MS Managed Ethernet Switch provides robust
transmission of (16) 10/100/1000BASE-TX and (4) 100/1000FX SFP ports, of gigabit
Ethernet data. Unlike most Ethernet switches, these environmentally hardened units
are designed for direct deployment in difficult out-of-plant or roadside operating
environments, and are available for use with either conventional CAT-5e copper or
optical transmission media. Diverse media selection allows for easy implementation
of point-to-point, linear add-drop, drop-and-repeat, star, or true self-healing ring and
mesh network system architectures. The 16 electrical ports support the 10/100/1000
Mbps Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/ MDIX features
are provided for simplicity and ease of installation. All SFP ports utilize ComNet SFP
modules for fiber and connector type and distance. These network managed layer 2
switches are optically (100/1000 BASE-FX) and electrically compatible with any IEEE
802.3 compliant Ethernet devices. Plug-and-play design ensures ease of installation,
and no electrical or optical adjustments are ever required. The CNGE20FX4TX16MS
incorporates LED indicators for monitoring the operating status of the managed
switch and network. These units are DIN-rail or wall mountable.
