SDI Video SFP optical module is different from other types of optical modules in the market. It is dedicated to high-definition SDI optical transceivers, which eliminates the phenomenon of no splash screen or black screen during high-definition image transmission. However, many people have very little knowledge of SDI Video SFP modules. C-Light gives a detailed introduction to the SDI Video SFP optical module and hopes to help you.
What is a digital video SDI interface?
The SDI interface is an acronym for the serial digital interface and is a digital video interface standard developed by the SMPTE organization. The serial interface is an interface that sequentially transmits individual bits of a data word and corresponding data through a single channel. Since the serial digital signal has a high data rate, it must be processed before transmission, which is a digital baseband signal.
SDI SFP modules can be divided into different categories according to different factors. For example, depending on the operating wavelength, they can be classified into three types: 1310 nm, 1490 nm, and 1550 nm. According to different types of transceivers, SDI SFP modules can be classified into five types: single-receiving,dual-receiving, single-transmitting, dual-transmitting, and transmitting and receiving. According to the transmission rate, they can be divided into three types: 3G-SDI, 6G-SDI and 12G-SDI SFP optical modules.
(1) 3G SDI Video SFP Optical Module
Transceiver-integrated 3G SDI Video SFP, supports data ill-conditioned frame transmission, conforms to SMPTE 297-2006 standard, supports SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M series working speed, widely used in high-definition audio-visual system, 3G SDI high-definition video matrix system .
(2) 6G-SDI SFP
The 6G-SDI SFP module has twice the data rate of the 3G-SDI module, which means it has a higher transmission rate. Therefore, the 6G-SDI SFP optical module is not only designed for SMPTE 259M/SMPTE 344M/SMPTE 292M/SMPTE 424M Serial digital video signal, and digital interface for SMPTE 2081. In addition, 6G-SDI SFP modules are also commonly used in camera, video, security surveillance applications and 4K/HDTV/SDTV service interfaces.
(3) 12G-SDI SFP
12G-SDI SFP modules with transfer rates up to 12Gbps can be used for SMPTE 259M, SMPTE 344M, SMPTE 292M, SMPTE 424M, ST2081 and ST-2082 serial digital video signals. In addition, 12G-SDI SFP optical modules are mainly used for SMPTE ST-297-2006, ST2081 and ST-2082 compatible optical interfaces and UHDTV/HDTV/SDTV service interfaces.
Conclusion
3G-SDI, 6G-SDI and 12G-SDI are digital video signals, they are bound to be limited in long-distance transmission, and 3G-SDI, 6G-SDI and 12G-SDI SFP optical modules can solve this problem.
