1 Ch Mini HD/SD - SDI Fiber Optic Extender with return RS485 Data

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 converter  compact, rugged, and portable converter boxes. Super-easy to use,  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 broadcasting 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 any cable is 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 singlemode or multimode fiber, and a range of transmitter power options can be selected.

Question and Answers

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 large core, so small pipes are going to the larger
ones so the light can pass through smoothly.
The opposite way would not work at all, MM to SM is an absolute no.
Iit would be better if you would have SM all the way, but since this
is only 600 feet it might work, we did 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.
