Product information "PFA Attenuating SM Patch Cables"
Single Mode Patchcords; 440 to 1625 nm; Attenuation 0.5 to 20 dB; Return Loss 50, 60 dB; Power Handling ≤2 W
OZ Optics’ PFA series of low cost fixed attenuating single mode fiber patchcords are ideal for high power applications and can be easily installed into fiber splice enclosures. The Attenuating Fiber Advantage: OZ Optics has recently enhanced its fixed attenuator product line by developing a new technology to precisely attenuate signals in fibers. This patent pending, fully automatable technique allows one to create fixed attenuators within any standard fiber, with low polarization dependent loss (PDL) and high power handling. The resultant attenuating fiber is physically identical in appearance and behaviour to the original fiber, allowing it to be used to build attenuating fiber patchcords. As the process used does not require the manufacture of special fiber, fixed attenuators can be constructed in small batch quantities economically. At the same time the automation aspect of the techniques allows large quantity orders to be manufactured at a reasonable cost.
Attenuating fiber is capable of handling up to 2 W of optical power at 1550 nm. The attenuating section is only a couple of millimetres to a couple of centimeters long, depending on the attenuation. The fiber used in OZ attenuators features a double cladding, with an absorbing dopant in the inner cladding layer. This double cladding structure effectively suppresses light scattering into the cladding. Thus the readings will not significantly depend on the application.
Attenuating patchcords are available with between 0.5 and 20 dB attenuation, in 0.1 dB increments. Higher attenuation levels and higher resolution attenuation steps are possible. Prototype and custom designs can be made quickly and in small volumes economically.
