Product Overview

LR-45-M is a general purpose 45 GHz bandwidth Lightwave Receiver module designed for optical communication, instrumentation, laboratory testing, ultra-broadband RF over fiber. Each unit of LR-45-M will be delivered with a complete calibration report, which is measured by a calibrated Agilent (NIST traceable) lightwave component analyzer.

LR-45-M utilizes a high sensitivity, wide bandwidth PIN photodiode and linear pre-amplifier that provides optical to electrical (O/E) conversion to frequency range up to 50 GHz. This compact module can be used in conjunction with the LT-40 to make an ultra-wideband RFoF link.
