The F-8SDI-3G-LOOP-TX/RX is an 8-channel 3G SDI fiber optic multiplexer with SDI loop-outs on the optical transmitter (TX) and dual outputs on the optical receiver

There are devices allowed to instantly move uncompressed SDI signals up to 3G 1080p/60Hz from place to place over only one single-mode fiber up to 20 km. With an additional very desirable option, the transmitter with 8 SDI inputs has loop output, and the optical receiver has dual outputs allowing to utilize one output and also has the ability to monitor on the second mirrored output .

It supports the following optical transport signals:

• 8 channels of HD/SD 3G-SDI signals over one single-mode fiber.
• 4 channels of 4K/UHD signals at 30 fps over one single-mode fiber.
• 2 channels of 4K/UHD signals at 60 fps over one single-mode fiber."

• CWDM optical multiplexing technology, Each SDI signal has its own laser and its beeing convert to the different optical wavelength
• Compliant with SMPTE ST 425-3, ST 425-5, 259M-2006, 292-2006, 424M-2006
