Nonzero Dispersion-shifted SM Fiber Spool

It is Truewave Reduced Slope (TWRS) fiber, see test data at the 9th photo. See year 1998 datasheet in 1st pdf link and year 2003 datasheet in 2nd pdf link below. 

Based on following tested zero dispersion wavelength and slope data, we verified that it is G.655 fiber, more specifically it is truewave RS fiber: Zero dispersion wavelength: 1467.93nm, dispersion slope at zero dispersion wavelength: 0.0524 ps /(nm2*km), spool length: 17.754km, tested by our local dispersion-test contractor at last pdf link below (see spool 8 in test report, there is typo error in dispersion slope), with GN Nettest dispersion receiver FD440 RX and transmitter FD440 TX, in July 2013. 

It is made in late 1999 or 2000. 

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 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.

Sample dispersion test data from manufacturer Lucent at the 4th pdf link below shows it is Truewave “-“ fiber, the zero dispersion wavelength is around 1558nm, maximum negative dispersion in 1525nm-1575nm is around -4.5ps/nm/km, the 2nd spool (20.451km) in this test sheet was verified by our dispersion test contractor in July 2013 at 3rd pdf link below (see spool 9 in test report). See more sample dispersion test data at last 4 pdf links from AT&T in 1999, they show dispersion over 1525nm-1575nm are negative. It 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. 

Slightly used with lead cables at each fiber spool end. It is made in late 1996.

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 3rd pdf link below.

Only one spool left.

Based on following tested zero dispersion wavelength data of different samples of same model, we conclude that it is G.655 fiber, more specifically it should be truewave "-" (truewave-negative) fiber : Zero dispersion wavelength: 1583.95nm or 1584.09nm, dispersion slope at zero dispersion wavelength: 0.0697 ps /(nm2*km) or 0.0774 ps /(nm2*km), tested by our local dispersion-test contractor at last pdf link below (see spool 5 and spool 6 in test report), with GN Nettest dispersion receiver FD440 RX and transmitter FD440 TX, in July 2013. 

We believe this “DXB” type fiber made in 1995 is same but earlier model of “DXC’ fiber (made in 1996), see “DXC” fiber details at Store product code: FSC-NZDSF-SPOOL-007C and FSC-NZDSF-SPOOL-007D. 

It 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.

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 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.
