Tucson, AZ, September 10, 2003. NP Photonics has developed an Optical Performance Monitoring (OPM) module that combines exceptional accuracy and an industry-standard platform. Based on the company's unique Compliant MEMS Fabry-Perot tunable filter, the OPM module measures optical signal-to-noise-ratio at 50 GHz to >25 dB with accuracy better than ± 0.5 dB.
A single detector covers both the C- and L-Bands (1528 nm to 1610 nm) with a resolution down to 2 pm, and an onboard wavelength calibrator ensures an absolute wavelength accuracy of ± 15 pm. Power accuracy is ± 0.5 dB across a 60-dB dynamic range. Polarization dependent loss is <0.1 dB.
The module features a standard DPRAM interface and includes a command set compatible with those used by major OPM suppliers. To further facilitate integration by system manufacturers, NP Photonics has designed the OPM module to fit into an industry-standard package that measures 220 mm x 110 mm x 32 mm.
"System manufacturers can easily integrate our OPM engine into their systems with little or no modification, allowing them to streamline product development and accelerate time to market," said Mike Blake, general manager of NP Photonics, UK. "This is also a lower cost alternative compared to other offerings on the market today, yet it delivers superior performance."
The OPM module fills the void left by component manufacturers who are no longer supporting legacy product lines. The standard form, fit and function ensures continuity for system manufacturers while an onboard digital signal processor allows the easy addition of new functions in the future. Reliable and cost-efficient, the OPM module is Telcordia compliant.
Founded in 1998, NP Photonics is the originator of Erbium Micro Fiber (EMF) technology and is dedicated to the design, manufacture and marketing of compact, low-cost, intelligent fiber-based products for the sensing and telecommunications industries. The company has developed a broad family of products based on its EMF and Compliant MEMS technology, including tunable filters, Optical Spectrum Analyzer Engines, fiber lasers, ASE Sources and fiber amplifiers.
