| PRELIMINARY DATA SHEET | MARCH 17, 2008 Applications High performance supertrunking links High power distribution networks Redundant ring architectures FTTx networks 2100 Series 1550 nm Externally Modulated Transmitter Features Single or Dual Optical Outputs Front Panel RF Test Point RS232 Control Interface Electro-Fluorescence Status Display OMI / RF Gain Adjustment AGC Select: CW, Video, Manual (No AGC) Industry Leading Field Adjustable SBS Suppression Field Adjustable Electronic Dispersion Compensation (EDC) EMCORE's DEMT/SEMT/HEMT/FEMT 2100 series product line is a family of stateof-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. 1 of 5 For more information on this and other products: Contact EMCORE Sales at 626-293-3400, or visit www.emcore.com. xEMT 2100 Series 1550nm Transmitter PRELIMINARY DATA SHEET | MARCH 17, 2008 Optical / Electrical Characteristics DEMT PROPERTY PERFORMANCE (note 1,2,3,4) Specified Link Length Channel Plan Output Power Noise Bandwidth SBS Suppression Carrier to Noise Ratio Composite Second Order Composite Triple Beat Composite Triple Beat UNITS L (km) Po (dBm) BW (MHz) (dBm) CNR (dB) CSO (dBc) CTB (dBc) CTB (dBc) DEMT2101 40 NTSC 80-Ch 11.0 4 > 12.0 54.0 -65 -65 -64 MODELS DEMT2102 40 PAL 60-Ch 11.0 5 >12.0 54.0 -65 -65 -64 DEMT2103 40 NTSC 110-ch 11.0 4 >12.0 51.0 -65 -65 -64 DEMT2104 40 PAL 89-Ch 11.0 5 >12.0 51.0 -65 -65 -64 COMMENTS Min.
