TRX-40G
The transmission link is intended for connection of measurement equipment (network analyzers, spectrum analyzers) to remote units under test especially in large-scale anechoic chambers. It can be used as a universal instrument for high-fidelity transmission of radio signals over long distances with low losses and as an alternative of legacy coaxial cable systems. The link features enhanced stability of frequency characteristics for metrologicalgrade applications.

TRX-40G consists of an optical transmitter, an optical receiver and a fiber optic cable (optional) with a single-mode optical fiber. The transmitter and receiver have two channels, which allows simultaneous and independent transmission of two radio signals using optical spectral multiplexing (CWDM) technology.
The transmission line has three variants:
— LN: equipped with an LNA at the optical transmitter’s input to provide low noise figure;
— HL: equipped with an LNA at the optical receiver’s output for better linearity;
— EA: without RF amplifiers which allows the consumer to independently choose the optimal amplifiers for different applications.
The receiver and transmitter are made in a dust- and moisture-proof housing, designed for use in harsh environment. TRX-40G has a built-in automatic control and diagnostic system that ensures optimal operating modes and monitoring of the operability of all components. The transmission line does not require adjustment and setup, and is ready for turn key operation.
