3998 Series 1550 nm Externally Modulated Transmitter DATASHEET | AUGUST 2012 FIBER OPTICS The L-type/D-type/S-type/H-type/F-type/N-type 3998 Series Applications High Performance Supertrunking Links High Power Distribution Networks Redundant Ring Architectures FTTx Networks RFOG Applications This product line is a family of state-of-the-art high performance 1550 nm externally modulated CATV fiber optic transmitters optimized for varying network applications. Packaged in convenient 1RU housing, this line of optical transmitters couples high optical output powers, up to 11.0 dBm, with low optical line width 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. 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. SAT-IF Transport DWDM Node Splitting 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 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 H-type series transmitters are optimized for single EDFA fiber links in the 70 to 90 kilometer range. These transmitters take advantage of our advanced fiber dispersion compensation circuitry to provide exceptional CATV performance. 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.
