Product Overview

The Optilab LR-30-M is a 30 GHz bandwidth PIN receiver module designed for RF over fiber, antenna remoting, and broadband RF transmission applications using single mode optical. The LR-30-M can accept input power of up to 40 mW. The LR-30-M utilizes a high input power, low distortion PIN photodiode that provides optical to RF conversion out to the frequency range beyond 30 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. When the LR-30 RF over fiber receiver module is linked with the LT 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/LL for more detail.
