Features
Telecordia TechnologiesTM 468 Compliant Industrial Temperature Range – Stable Even in Harsh Environments The 1615A 1310 nm DFB laser modules are designed for both wireless and distributed antenna system applications. This highly-linear OC-48 pinout compatible device delivers superior distortion performance over an enhanced temperature range of -40C to +85C. Performance Highlights Parameter Min Typical Max Units Wavelength 1300 - 1320 nm Slope Efficiency 0.30 - - mW/mA Temperature Range -40 - +85 C Frequency Range 5 - 2700 MHz nd Order IMD 62 - - dB rd Order IMD 70 - - dB Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
