Types of SDI Video SFP Optical Transceiver


SDI optical transceivers are known to many people, initially applied in the radio and television industry. SDI series optical modules include many types, such as SDI SFP optics(mainly includes 3G-SDI Video SFP, 6G-SDI Video SFP, 12G-SDI Video SFP), SDI SFP+ optical module(mainly includes 3G-SDI Video SFP+, 6G-SDI Video SFP+, 12G-SDI Video SFP+), etc. Then today we will talk about types of SDI video SFP optical transceivers.

What Is SDI Video SFP Optical Transceiver?

SDI SFP optical module and its related products are initially designed for the radio and television industry, applied for the television studio, animal filming, film shooting, large sports events live. It is extended to the 1080 PHD monitoring field. SDI SFP optical module is usually used on the SDI interface of the HD-SDI terminal device. The transmission rate and frequency for each different SDI interface are different.

An Introduction to Types of SDI Video SFP Optical Transceiver

SDI Video SFP transceivers can be divided into various types according to different factors. For example, on the basis of operating wavelength, they can be divided into 1310nm, 1490nm, 1550nm and CWDM wavelengths video SFP transceivers; based on transmission distance, there are 300m, 2km, 10km, 20km, 40km; based on operating rate, there are usually 3G-SDI, 6G-SDI and 12G-SDI video SFP optical transceivers.

3G-SDI transceiver module3G-SDI video SFP optical transceivers have a data rate up to 3Gbps, which are specifically designed for high performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M, and SMPTE 424M serial rates. They are generally used for television broadcasting. However, as technology advances, they are now also widely applied in global security applications such as high-end surveillance or unmanned systems, allowing simple designs or upgrades with full HD cameras.


6G-SDI video SFP optical transceivers’ data rate is intended to be twice as fast as 3G-SDI optical modules, which means it is supposed to deliver a payload of 6Gbps. Therefore, they are not only designed for SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M, and SMPTE 424M serial rates but also for SMPTE 2081. 6G-SDI video SFP optical transceivers are often used in the camera, video, security monitoring applications, and 4K /HDTV/SDTV service interfaces.

Speed up to 12Gbps, 12G-SDI video SFP transceivers are specifically designed for high performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M, SMPTE 424M, ST2081 and ST-2082 serial rates. They are mainly used for SMPTE ST-297-2006, ST-2081 and ST-2082 compatible electrical-to-optical interfaces and UHDTV/HDTV/SDTV service interfaces.

Above all is about the introduction to types of SDI video SFP optical transceiver.
