Singlemode Optical Fiber

For Visible and Near IR Transmission, EDFA Pigtailing, Acoustic Sensors and De-polarised FOGs

Specialty Single Mode Fibers Seven standard wavelengths, 488 nm to 1550 nm
Specialty Single Mode Fibers Exceptional bend-insensitivity
Specialty Single Mode Fibers 80 µm for high reliability and reduced form-factor

Fibercore Limited's Singlemode Optical Fibers have been proven to perform in a wide range of challenging applications including laser-doppler velocimeters, holography probes, EDFA pump pigtails, acoustic sensors and de-polarised FOGs.

The latest additions to the range responds to specific demands from the Telecommunications and Sensor Industries. SM980(4.5/80) and SM1250(9/80) address the need for reduced diameter fibers for the manufacture of small form-factor components for telecoms - SM1250(5.4/80) and SM1500(5.3/80) further increase the options available for hydrophones and de-polarised FOG. Just like all of our SM products, these new fibers are optimised for the fabrication of low-loss, fused-taper components and reliability tested to Telcordia™ standards.

SM980 is compatible with other fibers used in EDFA pump-laser pigtails and, when used to fabricate 980/1550 WDMs will effectively guide both pump and signal wavelengths. SM1500(6.4/80) and SM1500(4.2/125) may be used in any application in which low bend-induced loss is of paramount importance - both exhibit negligible excess loss, even when deployed in 100 m hydrophone coils only 10 mm in diameter. The increased germania content of SM1500(4.2/125) also enhances photosensitivity - facilitating the fabrication of certain types of fiber bragg gratings (FBGs).

1. The Design Wavelength is the wavelength (for 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. At the design wavelengths of 488nm and 514nm, the launched power must be considered carefully as these fibres have germanosilicate cores, and as such are susceptible to color center generation. For more information on this, please request a copy of Factnote 4.1.5.
