PACKING AND MARKING: The material shall be supplied in unsplice lengths in multiple of 2.1/2.2 Kms (i.e 10.5/12.6/25.2/50.4) or as per P.O , in plastic spools of dimensions:

Flange Diameter 240 mm +/- 10 %

Barrel diameter 150 mm +/- 10 %

Traverse diameter 100 mm +/- 10 % & 210 mm � 10 %

Overall diameter 110 mm +/- 10 % & 220 mm � 10 %

Bore Diameter 25.4 mm +/- 2 %

The material shall be packed in dust and moisture free packing., preferably with a plastic case. The packing should be good enough to withstand the rough handling during transportation. Temperature variation during transportation should not degrade the optical fiber properties. Each test report should have the following information

Manufacturers Name

Material Grade

Batch Number

PO Number

Each of the fiber spool shall has the following marking

Manufacturers Name

Material Grade

Spool ID

Length of the fiber

Attenuation at 1310 and 1550 nm
