Part Number: SWLD-1273X-X

Select Wavelength Laser Diodes (SWLD) from LAN/M/CWDM/DWDM: SWLD


Description:

The SWLD series laser is specifically developed fbr wavelength division multiplexing (WDM) systems. Selected wavelengths comply with ITU recommendations, both in channel definition of CWDM Wavelengths( 1270 to 1610nm),thus adhering to the 20nm grid and in channel definition of DWDM Wavelengths( 1527.22 to 1610.92nm),thus adhering to the 100GHz grid(0.8nm) relative to a frequency. It is available in a hermetic sealed 14-pin butterfly package. The laser diodes contain thermoelectric cooler (TEC), thermistor, monitor PD and optical isolator to secure high quality laser performance. We also have full customer selection of output powers, package types and output fibers of SM fibers, PM fibers and other special fibers. Our laser products are Telcordia GR-468 qualified, and in compliance with RoHS directives.
