NeoPhotonics announces integrated PLC triplexer

Mar. 3, 2006 – NeoPhotonics announced a planar lightwave circuit (PLC) triplexer module in a standard 2 x 2-inch package. Triplexer transceiver modules, located in customer equipment known as optical network terminals, are components of “fiber-to-the-home” networks.

NeoPhotonics said in a news release that the company believes achieving a standard form factor will provide network equipment manufacturers a simpler “plug and play” design process.

Like other triplexers, the NeoPhotonics PT8815 features a digital transmitter for signal transmission at 1310 nm upstream, a digital receiver for downstream reception at 1490 nm, and an analog receiver for video overlay at 1550 nm.

While conventional triplexers feature discrete components, the PT8815 integrates transmitter, receiver and filter functions into a single PLC chip, potentially reducing production costs in high volume.
