The CS-1000C series are small size Gigabit Ethernet - fiber converters designed to be media interfaces between 10/100/1000Base-T Ethernet copper pairs cable and 1000Base-X fiber optics cable. They feature a RJ-45 connector, and a pair of fiber optic connectors. The Gigabit Fiber Converters give you the freedom to extend your 10/100/1000 Mbps cabling distance by allowing connectivity 2 kilometers for multimode optical fiber and 20 kilometers using single mode optical fiber. 
LED indicators signal the power status of the converter, the Ethernet port and the FX port activity.
 

CS-G01F02M is a high-performance fiber media converter designed to facilitate seamless conversion between Ethernet twisted pair and optical signals. It features 1x1000M SFP port and 2x10/100/1000M RJ45 ports, enabling robust network connectivity with extended transmission distances of up to 100 km.
Engineered for exceptional reliability,
CS-G01F02M includes link fault alarms, a wide operating temperature range, and integrated lightning protection for both ports and power supply. These advanced features make it particularly well-suited for outdoor monitoring applications in rail transit, smart cities, and intelligent transportation systems.
 

Mini Converter Optical Fiber 12G converts SDI to optical fiber and optical fiber to SDI in both directions at the same time, you can even have different video standards going in each direction! The 12G‑SDI connections are multi rate, which makes it compatible with all SD, HD and Ultra HD formats and equipment up to 2160p60, including Level A and B devices. You can install any standard 3G, 6G or 12G‑SDI SFP optical fiber module so you can send SDI using the same low cost optical fiber cables that are commonly used for computer networks.
