Frequently Asked Questions


Q): Does this fiber converter can support 12G-SDI?


A): This device only supports 3G-SDI. but we offer two versions: 3G-SDI and 12G-SDI fiber converter. The 12G-SDI version is compatible with 6G-SDI and 3G-SDI. Please select your required 3G-SDI to fiber converter or 12G-SDI to fiber converter version in the corresponding section.

Q): What is the transmission distance of this 3G-SDI fiber converter? Does it support multi-mode fiber?


A): This device is equipped with a single-mode optical module, with a standard configuration of 20km transmission over single-mode fiber. For longer transmission distances, we can use higher optical power modules to support 40km and 60km transmission as needed. In addition, we do not recommend using multi-mode fiber. Please contact us if multi-mode fiber has already been laid in your system.

Q): Can a 19 inch 1U rack be chosen for the control room side?


A): Yes, this is a widely adopted configuration. The broadcast camera side can be a standalone unit (V-mount is also optional), and the control room side can be fitted with a 19-inch 1U rack, this design eases installation and management. This option is totally available; just inform us of your requirements before placing an order.
