SL-DSA EDFA

The SL-DSA EDFA family of optical amplifiers are optimized for extending the reach of analog and/or QAM DWDM multi-wavelength systems to over 100 km. In long-distance applications, chromatic dispersion causes the broadening of the optical signals. This broadening impacts the receiver’s ability to reproduce the original signal which manifests itself as an increased BER for digital signals and CSO for analog signals. The very low noise figure ensures meeting the most stringent Carrier-to-Noise (CNR) requirements that are encountered in RF video signal delivery. Unparalleled distance and performance are achieved when combined with the SL-Chromadigm chirp-free high OMI transmitters to reach outlying serving areas. The SL-DSA is a dual-stage EDFA with dispersion compensation to cancel the effects of chromatic dispersion in SMF-28 single-mode fiber enabling error-free transmission over greater distances especially when combined with the SL-Chromadigm series of multi-wavelength full spectrum transmitters. Dispersion compensation is available for 20, 30, 40, and 50 of SMF-28 fiber. The chassis is equipped to support two modular power supply modules working in a load share configuration with the option of a universal AC or -48 VDC powering for high network reliability. Status monitoring is provided through a local craft interface, CLI and SNMP (V4) based element management systems.
