Notes
- The parameters of cables in each separate case settle up according to specifications of the customer, depending on significances of intervals, sag and service conditions
- *Parameters of the transmissions are given for a standard monomode fiber of the type SMF 28 CPC 6 » CORNING Inc. » Manufacturing cable with a lower attenuation constant is possible through special order.
- The manufacturing of cable with another type of an optic fiber of CORNING—
.By single-mode with the unzero displaced dispersion of the type LEAF CPC 6
.Single-mode with boosted durability by the characteristics of the type SMF-28 with Duraclad CPC6
