Based on following tested zero dispersion wavelength data of other 2 samples of same model, we conclude that it is G.653 fiber (see G.653 fiber info at 2nd pdf link and also at page 20 of 1st pdf link below), more specifically it is Lucent dispersion-shifted fiber :
Zero dispersion wavelength: 1552.80nm or 1560.61.10nm, dispersion slope at zero dispersion wavelength: 0.0720 ps /(nm2*km) or 0.0717 ps /(nm2*km), tested by our local dispersion-test contractor at last pdf link below (see spool 10 and spool 11 in test report), with GN Nettest dispersion receiver FD440 RX and transmitter FD440 TX, in July 2013.

It seems this “DCB” type fiber is same as or similar to Corning DSF fiber.

Dispersion-shifted fiber (DSF), specified in ITU-T G.653, is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica-glass fibers to the minimum-loss window at 1550 nm. The group-velocity or intramodal dispersion which dominates in single-mode fibers is comprised of both material and waveguide dispersion. Waveguide dispersion can be made more negative by changing the index profile and thus be used to offset the fixed material dispersion, shifting or flattening the overall intramodal dispersion. This is advantageous because it allows a communication system to possess both low dispersion and low attenuation. However, when used in wavelength division multiplexing systems, dispersion-shifted fibers can suffer from four-wave mixing which causes intermodulation of the independent signals. As a result nonzero dispersion shifted fiber is often used.

DSF: To minimize chromatic dispersion at 1550 nm, a new fiber called dispersion-shifted fiber (DSF) was introduced in the early 1980's. By changing the index profile and reducing the core radius, fiber designers were able to move WL0 from the 1310 nm window to the 1540 to 1560 nm window. Though effective in greatly reducing chromatic dispersion effects, which limits bandwidth, the positioning of WL0 in close proximity to the operating wavelengths resulted in a tendency to a nonlinear distortion effect called four wave mixing (FWM). This is especially troublesome in DWDM applications with more than eight wavelengths. Typical losses range from 0.25 to 0.30 dB/km.

Note: Zero dispersion wavelength of standard DSF fiber is 1557.5 ±12.5 nm (i.e. 1544.5 nm to 1569.5 nm).

Condition Fiber roll looks a little loose, but the spool is still good for general transmission test. With attenuation test data from manufacturer(see 2nd and 5th photos). With original fiber length. Fiber attenuation and length is tested from fiber internal end by OTDR at our lab, see 2nd and 5th photos below. Without actual dispersion test data, see dispersion test data of different samples of same model at last pdf link above (spool 10 and spool 11 in test report).
