980/1550nm WDM

The 980/1550nm-pumped WDM is used specially in C-band Erbium Doped fiber Amplifiers(EDFA). This kind of WDMs can enable the combination of 980nm pump laser and 1550nm optical in Erbium Doped fiber to amplify. Fused 980/1550nm WDMs are designed with the special optical fiber.they have high isolation and good performance in applications.

  • Low Insertion Loss
  • High Isolation
  • Low PDL
