T-DCF13 - Double-Clad Fiber, 1250 - 1600 nm, Ø105 µm / Ø125 µm Cladding, Pricing Per Meter

Product Drawing

• Double-Clad Fiber for Simultaneous SM and MM Transmission 
  
  • Single Mode: 0.12 NA, 1250 - 1600 nm
  • Multimode: 0.2 NA, 400 - 2200 nm
• Cut-Off Wavelength of < 1250 nm

The DCF13 Double-Clad Fiber features a single mode core and dual cladding structure that allows both single mode and multimode light to propagate through the fiber. Single mode light travels in the Ø9 µm core of the fiber, while multimode light propagates in the Ø105 µm inner "1^st cladding".

Double-clad fiber is used in our Double-Clad Fiber Couplers,  where the core carries a single-mode signal and the 1^st cladding is used to efficiently transfer a multimode signal to the coupled multimode fiber. Other applications include CATV pump/signal couplers and light delivery/collection in fluorescence imaging. This double-clad fiber is not intended to be used with any of our active doped fibers. For applications that require matched active and passive double-clad fibers, we offer Yterbium doped fibers with matching passive double-clad fibers
