Background Loss @ 1100 nm (dB/km)
Low background losses.
-
260 ± 20
Coating Diameter (µm)
Outer diameter of the protective polymer coating.
Description
Passive components are usually manufactured with a passive fiber that matches the gain fiber as it greatly reduces splicing losses and maximizes transfer efficiency. The DCF-UN-20/125-100 is designed to perfectly match the DCF-YB 20/128P-FAC and is used for manufacturing the output isolator of high peak power pulsed fiber lasers.
Features & Benefits
- Compatible with industry standards
- Low background losses
- Excellent geometrical properties
Applications
- Passive component manufacturing
- Pulsed fiber laser systems
