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 21
st
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.

Laser Safety Information
CAUTION – use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous laser exposure.
CAUTION - invisible laser energy is present at the output(s) of the optical connectors. AVOID DIRECT EXPOSURE TO
THE BEAM. Laser output is invisible and eye damage may result.
CAUTION - do not attempt to open any optical connections with the laser enabled. Laser power up to 17.5 mW at
approximately 1550 nm could be accessible with optical connectors open.
One or both of the following precautionary labels can be found on the fiber optic connector bulkhead assembly located at
the rear of the transmitter.
DANGER
CAUTION
