Ortel’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 Ortel 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 19 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

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.
