Fibercore Advanced Singlemode Fiber Optics - Product Catalogue

Pump WDM and Laser Pigtailing Fibers

	SM fibers have perfectly matched refractive index profiles for low-loss tap couplers and WDMs
	All 980 nm fibers have dual wavelength (980/1550 nm) capability
	Bend-insensitive 80 µm SM980(4.5/80) for small form-factor 'Metro' packages
	Interchangeable with other manufacturers’ 980 nm fibers

Fibercore Limited now offers a range of singlemode and polarisation maintaining fibers designed specifically for the manufacture of EDFA components.

SM980 will guide both 980 nm pump and 1550 nm signal wavelengths, has a perfectly matched-clad structure and excellent geometry, facilitating both the fabrication of low-loss 980/1550 WDMs, fusion-splicing and laser-pigtailing operations. New SM980(4.5/80) has been introduced for 'Metro' or for any application in which small form-factor is important - it is ideal for use in conjunction with Fibercore MetroGain™ M12/980/80

HB980T and HB1480T are polarisation maintaining fibers designed specifically for the polarisation multiplexing of 980 nm and 1480 nm pump-diodes for high-power EDFAs. Both fibers offer excellent geometry and mode-field diameters matched to those of comparable non-PM fibers, to facilitate laser pigtailing.

1. The Design Wavelength is the wavelength (or wavelengths) at which the fiber is typically used. In practice, the fiber will transmit the TEM₀₀ mode at wavelengths of up to approximately 200 nm longer than the cut-off wavelength.
2. The Mode Field Diameter is a nominal, calculated value, estimated at the operating wavelength(s) using typical value of numerical aperture and cut-off wavelength.
3. Attenuation is a worst-case value, quoted for the shortest design wavelength.
4. Beat Length is measured at 633 nm for all HB fiber types. To a first approximation, beat-length scales directly with operating wavelength.
