The Thor 20GHz Transmitter F-RFoF-20GHZ-TX is a high-performance Lightwave Transmitter Module designed for analog photonics applications from DC to 20 GHz. This unit includes an 18 GHz optical intensity modulator and an Automatic Bias Control (ABC) board with four different operating modes. The external laser source can be any polarization-maintaining device, such as tunable laser, narrow linewidth laser, making it a versatile solution for RFoF system integration. Contact Optilab for more information.
The F-RFoF-20GHZ-RX is a 20 GHz photodiode module designed for RF over Fiber, antenna remoting, and broadband RF transmission applications using single mode optical. The F-RFoF-20GHZ-RX can accept input power of up to 35 mW. The F-RFoF-20GHZ-RX utilizes a high input power, low distortion PIN photodiode that provides optical to RF conversion out to the frequency range beyond 20 GHz. This compact, cost-effective receiver module can provide users with status monitoring through the use of an on-board processor that communicates to a host computer over an RS-232 I/O interface via a standard USB 2.0 port. When the F-RFoF-20GHZ-RX RF over fiber receiver module is linked with the TX series of RF over fiber transmitter modules, the combination provides an excellent solution for ultra-wideband RF to fiber conversion applications, go to optilab.com for more details
