Inventory DFB Distributed Feedback Laser OSFP

Fiber-coupled DFB lasers, including wavelengths from 1030 nm to 1550 nm, are available in stock and compatible with OSFP modules for high-speed optical applications.

Overview of DFB Lasers

Distributed Feedback (DFB) lasers are single-frequency, narrow-linewidth lasers where the optical feedback is provided by a periodic Bragg grating integrated into the gain medium, rather than discrete mirrors . This design ensures stable single-mode operation, minimal mode hopping, and high spectral purity, making them ideal for telecommunications, LiDAR, gas sensing, and quantum applications . DFB lasers can be temperature- and current-tuned over a small range (typically ±1 nm) to match specific system requirements .

OSFP-Compatible DFB Lasers

OSFP (Octal Small Form-factor Pluggable) modules are designed for high-speed optical transceivers, supporting data rates up to 400 Gbps. DFB lasers in OSFP packages are typically fiber-coupled, ensuring efficient integration into optical networks and sensor systems . Stock availability includes:

• Wavelengths: 1030 nm, 1064 nm, 1310 nm, 1550 nm, and any wavelength between 1250 nm and 1650 nm .
• Laser types: CW (continuous wave) or pulsed operation, compatible with ultra-narrow linewidth single-frequency emission.
• Packaging: Free-space or fiber-coupled, suitable for OSFP modules and high-speed drivers.
• Applications: Dense Wavelength Division Multiplexing (DWDM), high-speed fiber-optic communications, gas sensing, and precision measurement systems .
