EMCORE’s DEMT/SEMT/HEMT/FEMT 2100 series product line is a family of state-  
of-the-art high performance 1550 nm externally modulated CATV fiber optic  
transmitters. Packaged in a convenient 1U 19” rack housing, this line of transmitters  
couples high optical output powers, up to 11.0 dBm, with low optical linewidth  
resulting in unmatched performance. The characteristics of the EMCORE transmitter  
design exhibit high CNR when coupled with one or more EDFAs over 100km, or used  
stand alone up to 80km. The optical modulator, combined with the proprietary  
predistortion circuit, provides superior CTB and CSO performance with SBS  
suppression levels of greater than 20 dBm. Newly introduced 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. All of these  
characteristics together provide a line of high quality; industry-leading transmitters  
that have the versatility needed to support HFC networks far into the 21st century.

The DEMT series transmitters are designed to be employed 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 expensive and performance degrading  
EDFAs. This unique externally modulated transmitter technology allows the DEMT  
series of transmitters to be used in many novel HFC applications and architectures.  
The SEMT series transmitters are designed to be the most versatile model within the  
2100 series family of 1550nm externally modulated transmitters. 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. In  
addition, they will perform optimally in systems that require multiple optical splits and  
fiber branching incorporating unequal fiber lengths.  
The HEMT series transmitters are high performance, 1550nm externally modulated  
transmitters optimized for single EDFA fiber links in the 70 to 90 kilometer range.  
These transmitters take advantage of the 2100 series advanced fiber dispersion  
compensation circuitry to provide exceptional CATV performance. The HEMT series  
of transmitters provide a cost efficient, transport solution for medium to long  
distances  
The FEMT series transmitters are intended for use in FTTx 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) that  
normally limit performance in conventional externally modulated products.
