ANN ARBOR ? Advanced Photonix said Monday it has won a $625,000 initial purchase commitment from an unnamed Chinese telecom systems provider to supply its 40-gigabit-per-second high-speed optical receiver, the BR-40D, for long haul data communications.

All API would say is the provider is a key supplier to rapidly growing telecom markets such as China, India, Brazil and Russia. The sale will come through API subsidiary Picometrix.

API said the initial purchase commitment that will be delivered over the next three months exceeds $625,000 and has the potential to bear significant additional revenue during the coming fiscal year with follow on commitments.

Picometrix general manager Rob Risser, who is also CFO of API, said the sale ?confirms that our efforts at penetrating the China OEM market are beginning to bear fruit and could provide significant future revenue. This design win is only one of several design wins with tier 1 OEMs based in China that were are pursuing.?

Risser said API expects more sales of both its 40 gigabit-per-second and 100-gigabit-per-second products ?that will move to volume production status during the next fiscal year.?

Picometrix offers optical receivers in a wide variety of modulation formats. The company?s products use patented photodiode arrays to limit timing skew, which is important for DPSK modulation schemes that are used in dense wavelength division multiplexing systems. DPSK modulation takes advantage of phase modulation to extend transmission distances with high tolerance to crosstalk. This lowers cost for systems implementation and decreases power consumption.
