Extend HD-SDI or SD-SDI digital video signals over single-mode or multimode fiber optic cable
Thor compact SDI fiber extender kits are designed to increase the range of digital SD-SDI or HD-SDI video signals over single mode 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 this distance to more than 80 miles by using lasers to send the data over fiber cable.
TX/RX kit F-M1SDI-TX/RX with ST/PC connector supports single mode fiber up to 20Km or 2000 feet over multimode fiber
Cabled (coax-to-fiber) throw-down converters: compact, rugged, and portable converter boxes. Super-easy to use, it supports SMPTE 424M, 292M, and 259M as well as ASI and MADI audio. Its wide operating range, from 5Mbps to 1.5Gbps (3G-SDI 3Gbps model available*), supports most professional digital serial communications. Full error-free pathological pattern operation is fully compatible with professional fiber video interfaces. Single channel SDI fiber links are the smallest micro units that are suitable for a wide range of applications identical to where rattlers are used.
Single channel SDI fiber links are highly compact units that are suitable for a wide range of applications identical to where rattlers are used. Common uses include mounting on broadcast cameras to simplify cable distribution. Another common application is for high-end security systems. The F-M1SDI platform is ideal for security applications where the RS-485 serial data channel can be used to control pan, tilt, and zoom controllers at the camera mount. This also simplifies cabling.

Thor F-M1SDI fiber optic SDI transmitters and receivers use locking type ST fiber connectors and BNC video cables to ensure that cables are not accidentally pulled out of the device once the equipment is installed. Adapter jumpers are available by request for most types of fiber cables if a different fiber connector type is required. Options are available for both single-mode or multimode fiber, and a range of transmitter power options can be selected.

You might not need to pass through a media converter; we can't guarantee it, but it might work. Single-mode fiber has a very small core, multimode has a large core, so the light can pass through the larger one more smoothly. The opposite way would not work at all; MM to SM is an absolute no. It would be better if you had SM all the way, but since this is only 600 feet it might work; we have done it in the past. If that doesn't work, you might use 2 sets of the F-MSDI-Tx/rx back to back as a worst-case scenario.
3G-SDI and Ethernet over Fiber Extender - Video + Data Transmission up to 1080p60
1 Channel forward 3G SDI with loop out and Gigabit Ethernet (RJ45) over a single fiber (single mode) up to 20/40/80/120 km transceiver. The unit allows transmission of SD/HD/3G SDI up to 1080p/60 from the transmitter to the receiver while simultaneously extending Gigabit Ethernet connectivity between the two locations. The 12G 4K version is available (model dependent).
