Fiber Optic Remote Antenna Distribution System

The Optix™ remote antenna distribution system eliminates the need for expensive, fragile, and lossy coaxial cable by converting RF signal into light. Unprecedented runs of up to 10,000 meters are possible with nearly lossless transmission over 1310nm singlemode fiber cable. Optix works with any simplex (one-way) 50 ohm radio device between 100 MHz and 1000 MHz.

Each system includes a transmitter and receiver (or two of each for the diversity SKU). The transmitter is deployed at the remote antenna site and converts incoming RF from the antenna into optical signal. The signal travels via fiber optic cable to the Optix receiver module placed near the rack. The receiver converts the optical signal back to RF, and outputs to a BNC connector.

Optix, which is an RFoF technology, is designed for wireless audio receive applications. It has been used in multiple industries in a wide range of signal chain configurations. With appropriate in-line attenuation and re-amplification, it can be used for transmit applications as well.

Quite simply, OPTIX expands the possibilities of what wireless audio can do.


Use RF Optix for single channel or diversity reception. 

Can I use the RF Optix with IEMs and intercoms?
The RF Optix can be used with nearly any device so long as the bandwidth remains inside 100-1000 MHz, and the input to the transmitter does not exceed 0 dBm/1 mW. Comms and IEMs will exceed this input power threshold. Therefore, to use the RF Optix with coms and IEMs, you must pad/attenuate the incoming RF to below 0 dBm/1 mW and, depending on your application, amplify the signal back up on the other side. Many of our customers have done just this with great success, but in general using the Optix for transmit applications is considered “off-label,” and should be performed by experienced techs or with our help. See the User Guide for more information. 

How many channels of RF can the RF Optix handle?
The RF Optix has been demonstrated to carry up to 24 wideband FM wireless microphone signals.

At what distance does it become cost to effective to use F/O instead of coax?
If you’re playing a purely numbers game, RG8-X coaxial becomes more expensive than a single channel RF Optix kit with FC/APC terminated 1910 nm at about 250’. However, cost is not the only factor to consider. RG8X runs longer than 100’ are tricky without in-line amplification. Runs over 300’ are extremely difficult due to loss (30dB+), and noise introduced into the system from amplification. Coaxial cable is also very heavy, bulky, and vulnerable to damage. Fiber optic cable loses only .003 dB per foot, is more durable, and much lighter. Signal-to-noise ratios will always be vastly superior to coax runs when using fiber.
