IUS-3080/3062 series are managed Redundant Ring Ethernet switches with 6x10/100Base-T(X) & 2x100Base-FX, 1000Base-T, 1000Base-SX or 1000Base-LX ports. With its most advanced g-Ring technology, IUS-3080/3062 series can protect your mission-critical applications from network interruptions or temporary malfunctions with its maximum 1ms ultra fast recovery g-Ring technology. g-Ring is a ASIC based redundant ring that almost reach zero packet loss while networking is failure. It guarantees the recovery time less than 1ms even in gigabit Ethernet connection. Another innovative Open-Ring technology is also supported which can be applied for other vendor's proprietary ring technology. In addition, IUS-3080/3062 series can be managed centralized and convenient by a powerful windows utility X Open-Vision. In addition, the wide operating temperature range from -40XC to 70XC can satisfy most of operating environment. Therefore, the IUS- 3080/3062 series are the most reliable choice for highly-managed and Fiber Ethernet application.
