Description

Product feature:

  1. Adapt to standard single mode optical fiber G.652, 1525~1565nm transmission channel
  2. Excellent dispersion compensation feature can eliminate the influence to system’s index, because of residual dispersion.
  3. Dispersion compensation value range is 10~100Km optional.
  4. Low insertion loss, low polarized mode dispersion.
  5. Features Telcordia GR-2854-CORE qualified
  6. Reliability Telcordia GR-1221-CORE qualified

Different package styles, connector types and pigtail lengths available
