SL-CT1

The SL-CT1 full 1.218 GHz RF spectrum DWDM transmitters incorporate Sealight’s Chromadigm chirp cancellation and clipping mitigation technology, significantly advancing the performance of analog optical DWDM systems. The technology allows up to 40 consecutive, 100 GHz spaced ITU channels, while delivering exceptional MER and error-free, pre-FEC BER performance. Being void of distance tuning provides the flexibility to simply split the optical output into route diverse fiber rings without performance degradation or having to retune the transmitter when switched between different lengths of fiber. The SL-CT1 transmitter with its innovative technology sets the performance standard for DWDM full band systems offering a unique set of benefits:

• Chirp cancellation eliminates distance tuned pre-distortion, immunity to filter ripple induced distortions, and improved MER performance
• Adaptive clipping mitigation for error-free QAM performance and a high OMI for superior MER performance
• Reduces optical launch power requirement to avoid four-wave mixing and crosstalk issues

The SL-CT1 is offered with either a +6 dBm fixed or a variable (+9 to +15 dBm) output to support a wide variety of applications with one module. The SL-CT1 delivers very high MER/BER performance for redundant links or applications where a single wavelength per module is desired. Integrated, optical express ports can be added for extracting return path wavelengths along with an optical test point. The SL-CT1 occupies a single-width module providing eight transmitters in an SL-ChromaFlex 2RU chassis.
