Xponent Photonics Announces First Optical CATV Receiver

Xponent Photonics, the leading innovator of PLC optical components today announced the market release, and initial production of its XP7-0100 optical CATV receiver, an integrated high-linearity photodiode and RF amplifier for CATV HFC networks.

The receiver is based on the company's proprietary Surface Mount Photonics platform which allows the production of optical components that deliver exceptional performance and reduced footprint at a vastly lower price.

"Our initial products, triplexers and diplexers, are driving significant cost reductions for FTTx systems vendors," said Ramzi Sawires, Xponent's Director of Marketing. "Now we are able to provide the same benefits to the CATV market." Sawires went on to say, "With this product, the ability to extend the Xtreme package to a variety of applications has been demonstrated in production. Our first production customer is thrilled with the performance of this component."

Surface Mount Photonics is a superior technical platform for integrating optical receivers with RF amplifiers. With no hermetic seals or wire leads to manage, the interface between the photodiode and the RF circuit can be controlled by design, resulting in highly repeatable performance without the need for tuning or adjustment.

The Xponent XP7-0100 is designed for distribution optical nodes in HFC networks. It has a bandwidth from 50 - 1000 MHz, very low noise and excellent distortion performance. The RF amplifier is a balanced design to minimize second order distortion. An internal BALUN transformer converts the signal to a single-ended output.

Typical performance of the XP7-0100 CATV receiver is:

  • Gain variation over 50-1000 MHz, < +0.5 dB
  • Return loss at 1000 MHz, > 15 dB
  • Amplifier gain, 17 dB

Xponent is now accepting orders for the XP7-0100. Samples are available upon request. The Xponent CATV receiver is on display in Xponent's booth #3547 at OFC/NFOEC.
