Notes

*1. The parameters of transmission are given for a 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 optical fibers of CORNING:
  • Single-mode non-zero dispersion shifted fiber — type LEAF CPC 6
  • Multimode fiber 50/125 СРС6
  1. On demand of the customer, manufacturing cables with a sheath from flame retardant polyethylene is possible
