Notes

*1. The parameters of transmission are given for standard single-mode fiber type SMF 28 CPC 6 CORNING. The manufacturing of cables with a lower attenuation constant is possible through special order.

  1. The manufacturing of cables with other types of optic fibers of CORNING:
  • Single-mode with the non-zero dispersion shifted fiber — type LEAF CPC 6
  • Multimode fiber 50/125 СРС6 or 62,5/125
  1. On demand of the customer, manufacturing cables with a sheath from flame retandant polyethylene is possible
