Thor 3G SDI over fiber, 3G SDI Fiber Extender with RS485 control for data  

Optical Transmitter Receiver kit - F-1MSDI-3G-TX/RX  

Extend 3G, HD-SDI or SD-SDI digital video signals over single-mode fiber optic cable

3G SDI over fiber optic extender ST PC

Thor Fiber ultra compact 3G SDI fiber extender kits are designed to increase the range of digital 3G, SD-SDI or HD-SDI video signals over singlemode or multimode fiber optic cable. SDI is normally carried over coax cable on BNC connectors, however the maximum cable distance is limited to around 100 meters. Thor SDI extenders increase the distance to more than 80 miles by using lasers to send data over the fiber cable. 

F-M1SDI-3G-TX/RX kit with ST/PC fiber connector, supports single mode fiber up to 20Km  or 2000 feet over multimode fiber
