Description
Model OTOT-EM55XL 1550nm High Performance Externally Modulated optical transmitter is a high performance, dual optical output transmitter for analog and digital CATV signals and digital data. A continuous-wave (CW), 1550nm low RIN, high power, DFB source laser is used in conjunction with a Mach-Zendher lithium niobate electro-optic modulator, where the light is intensity modulated by the RF input signal. This external modulation technique produces a very low chirp signal which allows robust, high quality 1550nm transmission over conventional 1310nm non-dispersion shifted fiber such as SMF-28. The OTOT-EM55XL offers variable SBS suppression to +19dBm, bandwidth from 48-1,000 MHz and a sophisticated SNMP & web software interface. The Model OTOT-EM55XL is available in DWDM ITU wavelengths and has the unique ability to tune the DWDM channel ±100GHz from the front panel
