Selling EXFO FLS-235P – We Buy New Used FLS-235PA (‘s) Top Dollar Paid!

If you’re looking to Sell EXFO FLS-235P Pocket Pal Visual Fault Locator

EXFO FLS-235 Pocket Pal Visual Fault Locator
The Pocket Pal is EXFO’s easiest way to perform end-to-end fiber identification or to pinpoint breaks, macrobends, faulty connectors or splices, and other causes of signal loss, up to a distance of 5km. Compatible with singlemode and multimode fibers, this convenient loss finder emits bright red light at the exact location of the fault, often visible even through the orange or yellow jacket of a single fiber cable.

Thanks to its small size, light weight, and simple but proven design, the Pocket Pal can accompany you anywhere. In your pocket or in the supplied belt pouch, carry your FLS-235 along to the most demanding environment. To ensure ruggedness, it features rubber seals, fully enclosed laser head, and long-lasting mechanical switch which has been tested to provide a minimum of 100,000 operations without failure of apparent wear. The Pocket Pal has also been designed to withstand an accidental drop of 1 m (3 ft).

The standard Pocket Pal is equipped with a 635-nm source. Due to the spectral sensitivity of the human eye, this wavelength is about seven times more visible than a 670-nm wavelength. On the other hand, the 635-nm signal is attenuated almost twice as fast in a fiber. That is why you can also purchase a junior version of the Pocket Pal with a 670-nm source.

The choice of a particular version of the Pocket Pal depends on the distance range at which the unit will be most frequently used. The 635-nm version is more visible than the 670-nm version for a short distance but becomes less visible after a certain distance. For example, in an undamaged sinlgemode fiber, the estimated distance at which a 670-nm source becomes more visible than a 635-nm source is 1.76 km (about 1.1 mi).

Buying, Selling, Trading EXFO FLS-235P

The Pocket Pal features either a 2-Hz pulsed source (FLS-235P) or a continuous wave (CW) source (FLS-235C).
