AVARA TECHNOLOGIES. Optical FEC

Brochure

The Avara Forward Error Correction product is a rack mountable device for use in long haul optical links to improve the optical signal to noise ratio, increase Line power budget, and to increase transmission distances. It is a bidirectional OEO device with the FEC encoding and decoding functions designed specifically for SDH STM-4 / SONET OC-12 optical transmission systems. This device provides transmit-receive optical interfaces of client side and line side.

This product is compliant to ETSI and Telcordia standards.
