This product is a 1.58µm (L-Band) DFB-LD module with polarization maintaining optical fiber pigtail, suitable for use in 2.5Gb/s and 10Gb/s digital optical communication systems.
The FU-68PDF-V520MxxxB is a 1.58 µm (L‑Band) DFB‑LD module that includes a polarization‑maintaining optical fiber pig‑tail. It is designed for digital optical communication systems up to 10 Gb/s and can be used to expand wavelength channels into the L‑Band for Dense‑WDM transmission.
Key features include multi‑quantum‑well DFB laser diode, built‑in optical isolator, thermoelectric cooler, butterfly package, and an integrated photodiode for output monitoring. The module supports a selectable wavelength range of 1565 nm–1625 nm and provides detailed electrical, optical and thermal specifications for system designers.
