3998 Series 1550 nm

Externally-Modulated Transmitter

DATASHEET | OCTOBER 2013

CATV

The L-Type/D-Type/S-Type/F-Type/N-Type 3998 Series

The 3998 series 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 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.

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 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.
