DATASHEET| FEBRUARY 20, 2008 Model 1933F CATV Coaxial DFB Laser Diode 1310nm, Wide Bandwidth 5MHz – 2700MHz Emcore’s Model 1933F DFB lasers offer a low cost solution for linear fiberoptic links. These components can be cooled with external thermoelectric coolers for high stability, or run without TEC’s to reduce power consumption. The DFB laser builds upon Ortel’s long history of high performance, leading edge designs in CATV, wireless, and high speed digital applications. The laser diode devices are packaged in a compact hermetic assembly together with monitor photodiode and isolator, for Applications Video signal distribution in HFC and FTTx nodes flexible integration into various transmitter configurations. Performance Highlights High linearity, low power fiber links Operating Case Temperature Range Min Typical Max Units -40 - 80 °C 3 - 5.8 6 - 8.8 9 - 9.8 10 - 11.8 Features Linear DFB laser design Output power up to 10 dBm available Optical Output Power Bandwidth > 2700 MHz dBm RoHS compliance Frequency Range 5 - 2700 MHz Optical Isolator Carrier-to-Noise Ratio (79 channels) 51 - - dB Low power consumption Composite Second Order (79 channels) Standard Linearity - - -57 dBc Enhanced Linearity - - -60 Standard Linearity - - -65 Enhanced Linearity - - -68 Center Wavelength 1300 - 1320 nm Optical Return Loss 35 - - dB Side Mode Suppression Ratio, CW 30 - - dB Monitor photodiode Composite Triple Beat (79 channels) See following pages for complete specifications and conditions.
