Passave Adds Forward Error-Correction to EPON

Passave, a supplier of FTTH chipsets, releasing a sophisticated forward error-correction (FEC) mechanism for Ethernet-based passive optical networks (EPONs). The FEC capability enables the use of low-cost, low-power lasers for delivering Ethernet over low-quality transmission lines, such as lines using aging fiber.

Passave said the use of FEC doubles the reach of a FTTH network and doubles the number of customers that can be served from a single optical line terminal (OLT) in the central office. It also improves the cost-performance curve for FTTH.

FEC is a mechanism by which a transmitting system encodes data, enabling the receiving system to use redundant data to correct transmission errors. http://www.Passave.com
