LD4B-1510-DFB-2.5G-20

Laser Diode by LD4B

Note: Your Quotation Request will be directed to LD4B.

Check out our 1510 nm 20 mW (CW) 2.5 Gbps DFB laser diodes. You can pick from Single-Mode (SM) and Multimode (MM) optical fibers, depending on your needs. Great coupling stability vs temperature variation.

Choose the right package for you:

- Compact Coaxial with Bracket (COAXB), without Bracket (COAX) or compatible to Thorlab's mount (TH): This one is small and easy to mount.

- DIL-14-Pins Case (DIL or DILRAD): It comes with a built-in cooler and temperature control, so your laser works reliably in different conditions.

- BTF-14-Pins Type 1 (Pump): Standard 14-Pins Butterfly case, it includes an integrated TEC and thermistor to ensure temperature regulation, essential for the diode's stable performance.

You can also ask for specific fiber lengths or connector types to match your needs.

Our fiber-coupled laser diodes are great for both equipment makers and researchers.
