Alphion Corp. has announced two semiconductor optical amplifiers targeted for FTTx networks. Based on the proprietary QLight photonics technology platform, the QLight 1310- and 1490-nm amplifiers are designed to amplify upstream and downstream traffic, respectively. Both are protocol and data-rate independent and can be used as a transmitter power amp, a receiver preamp or an inline amplifier. The company says that the devices expand the limits of current technology, allowing PON systems to support greater numbers of users per node and faster data rates. They come in an industry-standard 14-pin butterfly package.
