3998 Series 1550 nm Externally-Modulated Transmitter DATASHEET | OCTOBER 2013 FIBER OPTICS The L-Type/D-Type/S-Type/F-Type/N-Type 3998 Series Applications High-Performance Supertrunking Links High Power Distribution Networks Redundant Ring Architectures FTTx Networks The 3998 series is a family of state-of-the-art high-performance 1550 nm externallymodulated CATV fiber optic transmitters optimized for varying network applications. Packaged in convenient 1 RU housing, this line of optical transmitters couples high optical output powers, up to 11.0 dBm, with low optical linewidth resulting in unmatched performance. The optical modulator, combined with proprietary predistortion circuitry, provides superior CTB and CSO performance with SBS suppression levels of greater than 21 dBm. Advanced features such as built-in field adjustable SBS control and electronic dispersion compensation allow these transmitters to be quickly optimized in the field for any link or application without the need to procure specifically tuned transmitters. This affords the system designer a level of flexibility previously unknown in the CATV market place. The L-Type series are designed as a high-performance solution for applications where the simultaneous transport of CATV and SAT-IF FM signals is required. The SAT-IF signals can be applied anywhere in the 950 to 2800 MHz band. RFoG Applications SAT-IF Transport DWDM Node Splitting The D-Type series are designed as a low cost, high-performance solution for applications where the required fiber length is in the range of 20 to 50 kilometers. Advanced, high power, DFB laser technology allows these transmitters to be fielded without the use of EDFAs. Features Single or Dual Optical Outputs QAM Loading to 1003 MHz Dual Power Supplies and Fans, Redundant & Hot Swapplable Front Panel RF Test Point SNMP Control Interface WEB GUI Vacuum Fluorescent Status Display OMI / RF Gain Adjustment AGC Select: CW, Video, Manual (No AGC) The S-Type series transmitters are designed to be the most versatile model within the 3998 series family. They can easily be configured to meet most HFC network solutions requiring link lengths in the range of 50 to 70 kilometers with one EDFA as well as links utilizing multiple EDFA’s. The F-Type series transmitters are intended for use in FTTx and RFoG architecture designs requiring high-quality transmission over varying transmission lengths and EDFA output powers. These transmitters successfully support very high optical launch powers while controlling the detrimental effects of Stimulated Brillouin Scattering (SBS), group velocity dispersion (GVD), and self phase modulation (SPM). The N-Type series transmitters are intended for use in node-splitting architecture designs requiring cost effective DWDM transmission over medium length fiber distances.
