SDI Over Fiber Solution
For Signal Transmission

Send your Production Signals over Remote
Locations without Quality Loss

Coaxial copper cables have the serious disadvantage of very limited distance when transmitting SDI or other broadcast production signals. This even gets more severe when the production signals are higher in quality and need wider bandwidths to be converted and sent. 

The best solution for this problem is using fiber optic cables plus SDI to fiber converter as an effective platform for signal transmission.

SAMIM solution of SDI over fiber, helps broadcasters to send their pre-recorded, taped, or live production signals to remote sites and distant TV broadcast studios easily, without quality loss.

To broadcast live from a distant studio, or OB vehicle, … the SDI video signals must first be transmitted to the central broadcast studio in the TV station's main building. To do so, broadcasters have a couple of options including satellite (SNG), microwave radio, bonded cellular, and also fiber optics (SDI to optical fiber converters). Fiber optics has many advantages over the other options especially if there has already been a fiber infrastructure available.
Using SDI over Fiber solution , broadcasters send and receive the SDI videos as they are; without any encoding, decoding, compression, processing, …. and this preserves the quality of the transmitted videos at the highest rate possible.
Moreover, SDI to Fiber signal conversion and transmission is a low-cost solution compared to other approaches for transmitting the signals to distant locations. In addition, sending more than one line of signals is much easier using fiber optics.
As in the above picture, (in the departure location) two or more lines of SDI signals are converted to Fiber optic signals by EOD, then multiplexed in a single line by OMD equipment. Next, (in the destination) the single fiber line is de-multiplexed by OMD into two or more fiber lines and then converted to SDI signals back again by Samim OED equipment. The good point is that OED equipment provides distribution capabilities to duplicate the desired signal lines.

Fiber Optic Multiplexers and De-Multiplexers

Another important piece of equipment in Samim SDI over Fiber Solution is CWDM modules. They can merge several input optic signals with different wavelengths into a single line of data packets to be transmitted over a fiber optic channel. Conversely, the de-multiplexer modules receive the signal line and split it into several optic outputs. As very adaptive and scalable tools, CWDM modules are usually able to transmit live signals to desired remote points without the need to expand the signal contribution infrastructure; even if the audio/video input sources increase.
