Optical Booster Amplifier | OBA-17

Supplier: Avara Technologies

Avara RAMAN- and EDFA-based Optical Amplifiers provide an efficient, cost-effective and reliable way to deliver long-haul PDH, SDH and Giga bit Ethernet transmission solutions

Price Guide: POA

The Avara optical pre-amplifier product is rack mountable RAMAN Amplifier with integrated EDFA pre-amp and DCM modules for use in long haul optical transmission applications.

These units are designed for PDH, SDH, SONET and optical Ethernet transmission applications, and has been developed to integrate with optical telecommunication equipment manufactured by any vendor.

The products provide integrated RAMAN and EDFA technologies, compliant to ETSI and Telcordia standards.


The Avara optical amplifiers can be used in applications to extend the range of equipment operating at 1550nm (C-band).

Assuming a fibre loss of 0.22 dB/km, the booster in conjunction with the preamp can extend the range of a typical transmission system by up to 200km once typical losses are factored in.
