NeoPhotonics Intros Integrated Coherent Receiver with an Integrated Polarizing Beam Splitter

NeoPhotonics, a leading designer and manufacturer of photonic integrated circuit, or PIC, based modules and subsystems for bandwidth-intensive, high-speed communications networks, has released new PIC-based Integrated Coherent Receiver (ICR) for 40 and 100 Gbps DWDM transmission systems that incorporates an integrated polarizing beam splitter (PBS).

The company has brought in these new ICR series to eliminate the need for system designers to place a PBS externally, decreasing circuit board footprint requirements. The product supports the OIF (News - Alert) Implementation Agreement for Integrated Dual Polarization Intradyne Coherent Receivers.

It also offers advanced demodulation to analyze the state-of-polarization and optical phase of a phase-modulated signal relative to an externally supplied optical reference signal, enabling recovery of the phase-polarization constellation of 100 Gbps Dual Polarization Quadrature Phase Shift Keyed (DP-DQPSK) format signals.

“Key benefits of the NeoPhotonics (News - Alert) ICR with an integrated PBS include that it allows customers to eliminate an external beam splitter from line cards and simplifies fiber routing,” said Tim Jenks, chairman and CEO of NeoPhotonics. “By using our photonic integration technology, we are able to integrate the PBS without changing the ICR form factor, streamlining the design-in process for our customers,” he concluded.

The company has recently announced that its PIC products had accumulated more than 3 billion hours of operation without a reported field failure. The company claims that since 2003, it has shipped more than 240,000 PIC modules for deployment in telecommunications networks around the world, including thermally stabilized AWGs, Athermal AWGs, Coherent Mixers for 40 and 100Gbps coherent systems and splitters for FTTH PON networks.

Together, these products have operated in the field for more than 3 billion hours. Without reported field failures, the upper limit on the FIT rate of NeoPhotonics PIC products is 0.3. A FIT rate of 1 represents one failure in a billion hours of operation.
