1764

1764 1550 nm C-Band DWDM DFB Laser Module DATASHEET | JULY 2013 FIBER OPTICS The 1764 laser module is a Dense Wavelength Division Multiplexing (DWDM) laser for analog wireless and distributed antenna system (DAS) applications. It features a distributed-feedback (DFB) device that has been designed specifically for radio frequency (RF) and wireless applications. The 1764 laser has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. Applications Wireless Networks DAS Applications Architectures Using Separate Optical Wavelengths to Carry Targeted Services The 1764 is available in all C-band ITU grid wavelengths.
