  Lightwavestore.com :: Fiber/Cable Spools :: Nonzero Dispersion-shifted SM Fiber Spool :: 25km or 30km Lucent/AT&T Truewave "-" fiber spool. With negative dispersion around 1550nm. Without fiber connectors. 'UFO' Fiber. Without actual dispersion test data.

  25km or 30km Lucent/AT&T Truewave "-" fiber spool. With negative dispersion around 1550nm. Without fiber connectors. 'UFO' Fiber. Without actual dispersion test data.. Store Product Code: FSC-NZDSF-SPOOL-006K
25km or 30km Lucent/AT&T Truewave "-" fiber spool. With negative dispersion around 1550nm. Without fiber connectors. 'UFO' Fiber. Without actual dispersion test data.  Store Product Code: FSC-NZDSF-SPOOL-006K

Based on following tested dispersion data of other 2 samples (Store Product Code: FSC-NZDSF-SPOOL-006J), we conclude that it is G.655 fiber, more specifically it is truewave "-" (truewave-negative) fiber:
Zero dispersion wavelength: 1585.38nm or 1607.82nm, dispersion slope at zero dispersion wavelength: 0.0510 or 0.0552 ps /(nm2*km), tested by our local dispersion-test contractor at last pdf link below (see spool 12 and spool 13 in test report), with GN Nettest dispersion receiver FD440 RX and transmitter FD440 TX, in July 2013.

Truewave “-“ fiber can work with truewave plus fiber together for average zero dispersion in ultra long haul fiber transmission, this fiber combination is also called dispersion-management fiber.

Some spools are labeled ‘UFO Fiber’. The photos below show 14 spools in sequence, 1st to 7th photos are for Sample A and Sample B, rest photos are for Sample C to Sample N.

We do not know the manufacture year, but we guess they were made between 2003 -2006, since they came with 'DXC', 'DXB', and 'DXD' fibers together which were made in 2003-2006. See truewave "-" fiber of another model ('DXC' fiber) at Store Product Code: FSC-NZDSF-SPOOL-007C.

The following message is from http://www.olson-technology.com/mr_fiber/Fiber_Types.htm
NZ-DSF was developed to counteract the FWM limitations of DSF. The idea is to move lambda0 to either end of the 1550 nm band, thus ensuring that all of the wavelength channels have slightly different optical speeds in the fiber. Common brands are TrueWave Classic (Lambda0 < 1530 nm), TrueWave Plus (Lambda0 = 1497 nm), TrueWave RS (Lambda0 < 1452 nm) by Lucent, and SMF-LS (Lambda0 > 1560 nm) by Corning. The advantage that these fibers have over DSF is a compromise solution of a slightly lower degree of integrated dispersion compensation for a higher tolerance to non-linear distortion effects. Available with positive dispersion (+D) NZ-DSF and negative dispersion (-D) NZ-DSF.


The following message is from 2nd pdf link below:
--------------------------------------------------------------------------------------
The first generation of Truewave fiber was originally developed in 1993 by ATT. Since then, the Truewave family has evolved under the Lucent brand.

After the TW-AT&T, the next member of the family was named Truewave Classic (TW-C). In the data
sheet below, we notice a slightly higher CD coefficient and a slightly reduced dispersion slope compared to the TW-AT&T.

Following the TW-C, Lucent introduced the Truewave Plus (TW+). Even in this case the CD properties
have been modified. The rest of the optical parameters are left unchanged.

The Truewave evolution continued with the introduction of major changes in the Truewave Reduced Slope (TW-RS), which, according to Lucent, represent the largest part of installed Truewave. The TW-RS is characterized by a higher CD and shows a decrease of about 36% in the dispersion slope. These two
properties translate in a performance improvement for high-density DWDM applications.

The latest member of Truewave family, the Truewave Reach, has been introduced in 2002. The TW Reach is a fiber optimized for application in the S, C and L band and for Raman assisted amplification. (The datasheet is currently not available).
---------------------------------------------------------------------------------------

It is ITU G.655 fiber, see ITU G.655 fiber info at 1st pdf link below.

Details
 
Quantity14 item(s) available (total)
Condition Very good cosmetic condition, fiber roll is like new or very good. Without attenuation test data from manufacturer. With original full fiber length. For 9 samples of total 16 spools including Store Product Code FSC-NZDSF-SPOOL-006J, by OTDR measurement, fiber attenuation is verified good from internal fiber end of spool (from 0.199 to 0.209dB/km), and spool fiber length is verified matching product data label at our lab, see photos below. So rest 7 untested spools (with better or same cosmetic condition) should have same attenuation results. At the top of spool drum, the internal fiber is several meters long, so you can do optical transmission test. Without actual dispersion test data, see dispersion test data of different samples of same model (Store Product Code: FSC-NZDSF-SPOOL-006J) at last pdf link above (spool 12 and spool 13 in test report).
