Triple-Clad Doped Fiber
Fibercore’s triple-clad doped fibers aredesigned for fiber lasers and high power CATV and telecoms amplifiers. Theirunique triple cladding structure is designed to encapsulate the octagonal modemixing pump guide within a circular outer cladding, enabling lower splicelosses and lower splice variability associated with fibers with octagonal outerregions. This triple cladding structure also gives an additional modeconfinement structure to reduce the amount of pump light at thecladding-coating interface to aid coating reliability.
Fibercore’s triple-clad erbium/ytterbiumdoped fibers (TC1500Y) are designed as single-mode, high-power CATV andtelecommunications amplifier fibers. The TC1500Y(6/125)HD offers a smaller ModeField Diameter (MFD) for higher efficiency levels at output signal power around1W. The TC1500Y(11/125)HD is designed for output signal power at 5W and above.
The TC1060Y(10/125)0.08HD is a ytterbiumdoped fiber designed for use in pulsed and CW fiber lasers. The composition isoptimized to avoid the effects of photodarkening to ensure long lifetime andhigh reliability.
TypicalApplications:
· High Power Erbium Doped Fiber Amplifiers (EDFAs)
· Ytterbium/Erbium Doped Fiber Amplifier (YEDFA)
· Fiber Lasers
· Light Detection and Ranging (LIDAR)
· Cable Television (CATV)
