About 2.5km SM fiber spool. 'Sell As Is', no Warranty.

As shown at the product label on the drum at 2nd and 3rd photos below, NA=0.97/0.100; Atten=0.454dB/km; Core/Clad diameter: 8.847/123.8um (top), 8.872/124.1um (bottom). This is very old fiber, 250um-coating bare fiber, in big drum, about 2.5km long. The note on the box shows (see 4th photo below): SMF spool for 1.55um application, total loss of two cascaded spools is 3.4dB at 1557nm. It seems old dispersion shifted fiber, or old regular SMF. There is SMF/DSF order sheet in the box, see last photo below, but we cannot guarantee this sheet is for this fiber spool.
