Covega's 12.5 Gb/s Intensity Modulator is part of the Mach-10™ product line, a family of high performance, superior quality 10+ Gb/s External Optical Modulators. The 12.5 Gb/s Intensity Modulator was specifically designed for OC-192 customers requiring greater bandwidth to implement FEC. Increased bandwidth to 12.5 GHz at 3dB down is critical to effectively implement advanced encoding schemes such as Super FEC and Digital Wrapper (G.709).

Like all modulators in the Mach-10™ product line, the 12.5 Gb/s Intensity Modulator is based on the Mach-Zehnder interferometric architecture, using titanium-indiffused lithium niobate substrates, making it ideally suited for Super FEC applications. The 12.5 Gb/s Intensity Modulator is available bias trimmed for near-zero volt operation at quadrature.

Key features of COVEGA's 12.5 Gb/s Intensity Modulator include:

• Superior Frequency Performance

• Low Drive Voltage

• Long-Term Bias Stability

• Hermetic Packaging

• Zero Chirp

• High Reliability

• C&L Band Operation

• Tested to Telcordia GR-468
