openGear 2-Channel 3G-SDI to Single-Mode LC
Fiber Transmitter for CWDM

The OG-FIBER-2T-X is a state of the art, openGear compatible, 2-channel 3G-SDI to Fiber converter with CWDM SFP options, enabling 3G-SDI signals to be extended up to 10 km (32,808 ft) over standard single-mode fiber optic cable. The two 3G-SDI inputs are completely independent allowing different 3G-SDI rates to be carried on each channel.

openGear Compatibility

The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rackframe products.


The 3G-SDI inputs are re-clocked with best-in-class input jitter tolerance. 3G-SDI rates of 270Mb, 1.5Gb, and 3Gb are supported. The fiber connector is attached to the main card for added reliability and cost savings.


  • Automatic detection and re-clocking of 270Mb, 1.5Gb, and 3Gb SDI data rates
  • “Input Present” and “Input SMPTE Lock” LEDs
  • Hot-swap capable
  • Compatible with DFR-8321 and OG3 openGear frames
