Description:
The DEMT/SEMT/HEMT/FEMT 2100 series products are 1550 nm externally modulated CATV fiber optic transmitters with high optical output powers, up to 11.0 dBm, and low optical linewidth resulting in unmatched performance.
The DEMT series transmitters are designed 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.
The SEMT series transmitters are easily 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 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 FEMT series transmitters are intended for use in FTTx architecture designs. 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. |
