・Wavelength Converters - to interface 1310 nm short-haul data transmission to optically amplified systems. Data rates from E2 to STM-16 are available.

・Power Amplifiers - for post amplification before launching the signal into the link. Power amplifiers are available with saturated output powers from 7 to 21 dBm for both single channel and DWDM applications.

・Preamplifiers - to enhance effective receiver sensitivity; these preamplifiers provide one of the lowest noise figures in the industry.

・Raman Pump Sources - to provide distributed Raman amplification for long reach requirements.

・Raman Pump Source, Amplifier, PreAmplier and Transponder Cards, and Alarm and Monitoring Units are configured into our subrack. These PIUs are ‘hot-swappable’ for maintenance and repairs with the minimum disturbance to traffic on the network.

・The Remote Equipment Management (REM) - Series, provides the RMH subrack with local and remote monitoring and control. From 200 km to 500 km and beyond, the RMH-Series has the equipment that will support your complete telecom system needs.
