The L-type/D-type/S-type/H-type/F-type/N-type 3998 Series
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.
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.
