Series Overview
SFNT Overview
Unmanaged switches are extremely reliable and easy to maintain, suitable for low-cost and reliable Ethernet networks.
For long-distance or high-interference application scenarios, various types of products with fiber optic interfaces are provided for your choice. You can choose switches that have both electrical ports and SC or ST fiber optic interfaces.
The SFNT series switches are designed for extreme environmental conditions and high-demand application scenarios, such as the oil and gas industry, shipbuilding, and other outdoor application scenarios. In addition, all SFNT switches provide an alarm contact and link monitoring, and realize relevant functions through important diagnostic options.
Features:
- Operating temperature range: -40°C - +75°C
- Status display LEDs and standard alarm contacts
- Cable locking and port locking accessories can be installed on the switch
- Redundant power supply
Advantages:
- Speed auto-negotiation and port auto-crossing technology make network creation and expansion easier
- Optional gigabit products are suitable for large-traffic data transmission
- Electrical isolation technology and optional fiber optic output function enable trouble-free operation in industrial environments
