Product Overview

The QAMnet rEDFA series of Erbium Doped Fiber Amplifiers (EDFA) are reliable and cost-effective optical amplifiers for use in HFC, FTTH, PON and deep fiber applications. By combining 980 nm/1480 nm pump laser modules and a high efficiency Erbium doped fiber, the rEDFA amplifiers deliver output up to +24 dBm, while maintaining a low noise figure (NF).

Depending on pump lasers configuration, the rEDFA amplifier produces optical output level from +17 dBm to +24 dBm. In conjunction with other QAMnet transmitter products, the rEDFA can be used for transmitting forward 1550 nm analog channels and/or 100% QAM256 modulated signal channels. The rEDFA is housed in a standard 19” 1RU rack mount unit.
